Background:
This study compared the 5-year outcomes of isolated proximal femoral varus osteotomy (FO) and combined proximal femoral varus and pelvic osteotomy (FPO) for the treatment of hip displacement in children with cerebral palsy (CP) in Sweden, focusing on the number of reoperations and residual hip displacement.
Methods:
The study included 163 children with a 5-year follow-up after FO or FPO in the national Swedish CP surveillance program, CPUP. Descriptive statistics and univariate and multivariate Cox regression analyses were used to identify whether the age at surgery, sex, Gross Motor Function Classification System level, CP dominant symptom, hip migration percentage (MP), type of surgery (unilateral/bilateral), and history of soft tissue hip surgery were related to the 5-year outcomes after surgery. Failure after hip surgery was defined as a skeletal reoperation involving the hip and/or MP >50%.
Results:
During the period 2001 to 2017, 163 children (65 girls) underwent 246 femoral and/or pelvic osteotomies (154 FO, 47 bilaterally; 92 FPO, 16 bilaterally) and had a 5-year follow-up; 95 and 74 children had ≥1 FO or FPO as the primary skeletal surgery, respectively. The mean preoperative MP (51%±18% for FO and 59%±17% for FPO, P=0.001) and age at surgery (6.2±2.5 years for FO and 7.3±2.8 years for FPO, P=0.014) differed between procedures. At the 5-year follow-up, 5 hips (5%) had reoperations and 5 hips (5%) had radiological failure among the 92 FPOs, and 33 (21%) had reoperations and 14 (9%) radiological failure among the 154 FOs. The difference in outcome failure rate was significant (P<0.001). Multivariate Cox regression analysis showed a lower risk for failure with FPO [hazard ratio (HR)=0.32, 95% CI: 0.15-0.68] compared with FO. A higher preoperative MP increased the risk for outcome failure (HR=1.21, 95% CI: 1.15-1.36 for each 5% increment).
Conclusions:
FPO had a higher mean preoperative MP but a lower 5-year outcome failure rate compared with FO. A higher preoperative MP was associated with an increased risk of failure.

Background:
There are now recognized standards of care published by the British and American Orthopaedic Associations which detail key areas of evidence-based recommendations for the treatment of children with displaced supracondylar humerus fractures. Although many aspects of treatment are covered in these recommendations, both the American and British Orthopaedic Associations do not recommend the exact duration of immobilization postoperatively.
Methods:
This study retrospectively compared outcomes of operatively managed supracondylar fractures immobilized postoperatively for short immobilization (SI) defined as 28 days or less, with long immobilization (LI) defined as more than 28 days. The outcomes measured were clinical (deformity, range of motion, and pin site infection) and radiologic (loss of position after the removal of K-wires, Baumann’s angle, anterior humeral line, refracture, and signs of osteomyelitis). Demographic data were recorded to evaluate and ensure satisfactory matching of the 2 groups for analysis.
Results:
The study included 193 pediatric supracondylar fractures over a 4-year period which were treated with manipulation under anesthetic and K-wire fixation. The difference in average time in plaster between the 2 groups was statistically significant (SI: n=27.5 d, SD 1.23; LI: n=43.9 d, SD 15.29, P=0.0001). Data for operative techniques—closed or open reduction (SI: n=66, LI: n=78, P=0.59), and crossed wires (SI: n=37, LI: n=50, P=0.57) between the two groups showed no statistical significance. There was no statistical difference between the groups for the average number of days postoperatively at which wires were taken out (SI: n=28.9 d, SD 5.95, LI: n=30.1 d, SD 5.57, P=0.15), number of pin site infections requiring antibiotic treatment (SI: n=3, LI: n=5, P=0.70), or children from each group who were recorded to have regained full range of motion symmetrical to their contralateral arm (SI: n=79, LI: n=99, P=0.74).
Conclusions:
Our study therefore suggests that shorter immobilization of these patients (SI group) does not yield a higher rate of complications including refracture and malunion.

Background:
Little is known about the prevalence of intraspinal pathology in children who toe walk, but magnetic resonance imaging (MRI) may be part of the diagnostic workup. The purpose of this study was to examine the role of MRI for children who toe walk with a focus on the rate of positive findings and associated neurosurgical interventions performed for children with said MRI findings.
Methods:
A single-center tertiary hospital database was queried to identify a cohort of 118 subjects with a diagnosis of toe walking who underwent spinal MRI during a 5-year period. Patient and MRI characteristics were summarized and compared between subjects with a major abnormality, minor abnormality, or no abnormality on MRI using multivariable logistic regression. Major MRI abnormalities included those with a clear spinal etiology, such as fatty filum, tethered cord, syrinx, and Chiari malformation, while minor abnormalities had unclear associations with toe walking.
Results:
The most common primary indications for MRI were failure to improve with conservative treatment, severe contracture, and abnormal reflexes. The prevalence of major MRI abnormalities was 25% (30/118), minor MRI abnormalities was 19% (22/118), and normal MRI was 56% (66/118). Patients with delayed onset of toe walking were significantly more likely to have a major abnormality on MRI (P=0.009). The presence of abnormal reflexes, severe contracture, back pain, bladder incontinence, and failure to improve with conservative treatment were not significantly associated with an increased likelihood of major abnormality on MRI. Twenty-nine (25%) subjects underwent tendon lengthening, and 5 (4%) underwent neurosurgical intervention, the most frequent of which was detethering and sectioning of fatty filum.
Conclusions:
Spinal MRI in patients who toe walk has a high rate of major positive findings, some of which require neurosurgical intervention. The most significant predictor of intraspinal pathology was the late onset of toe walking after the child had initiated walking. MRI of the spine should be considered by pediatric orthopedic surgeons in patients with toe walking who present late with an abnormal clinical course.

Background:
The management of first-time patellar dislocation remains variable, with limited evidence to support or compare different operative and nonoperative modalities. The primary aim was to establish consensus-based guidelines for different components of nonoperative treatment following a first-time patellar dislocation. The secondary aim was to develop guidelines related to management after failed nonoperative treatment. The tertiary aim was to establish consensus-based guidelines for the management of first-time patellar dislocation with a concomitant osteochondral fracture.
Methods:
A 29-question, multiple-choice, case-based survey was developed by 20 members of the Patellofemoral Research Interest Group of the Pediatric Research in Sports Medicine Society. The survey consisted of questions related to demographic information, management of first-time patellar dislocation without an osteochondral fracture, and management of first-time patellar dislocation with a 2 cm osteochondral fracture. The survey underwent 2 rounds of iterations by Patellofemoral Research Interest Group members and the final survey was administered to Pediatric Research in Sports Medicine members, using REDCap. Consensus-based guidelines were generated when more than 66% of respondents chose the same answer.
Results:
Seventy-nine of 157 (50%) eligible members responded. Sixty-one were orthopaedic surgeons and 18 were primary sports medicine physicians. Eleven consensus-based guidelines were generated based on survey responses. Those that met the criteria for consensus included initial knee radiographs (99% consensus), nonoperative treatment for first-time patellar dislocation without an osteochondral fracture (99%), physical therapy starting within the first month postinjury (99%), with return to sport after 2 to 4 months (68%) with a brace (75%) and further follow-up as needed (75%). Surgical treatment was recommended if there were patellar subluxation episodes after 6 months of nonoperative treatment (84%). Patellar stabilization should be considered for a first-time dislocation with an osteochondral fracture (81.5%).
Conclusion:
Consensus-based guidelines offer recommendations for the management of first-time patellar dislocation with or without an osteochondral fracture. Several changing trends and areas of disagreement were noted in clinical practice.
Clinical Relevance:
In the absence of high-level evidence, consensus-based guidelines may aid in clinical decision-making when treating patients following a first-time patellar dislocation. These guidelines highlight the evolving trends in clinical practice for the management of first-time patellar dislocation. Areas not reaching consensus serve as topics for future research.

Background:
Thoracic anterior vertebral body tethering (TAVBT) is an emerging treatment for adolescent idiopathic scoliosis. Tether breakage is a known complication of TAVBT with incompletely known incidence. We aim to define the incidence of tether breakage in patients with adolescent idiopathic scoliosis who undergo TAVBT. The incidence of tether breakage in TAVBT is hypothesized to be high and increase with time postoperatively.
Methods:
All patients with right-sided, thoracic curves who underwent TAVBT with at least 2 and up to 3 years of radiographic follow-up were included. Tether breakage between 2 vertebrae was defined a priori as any increase in adjacent screw angle >5 degrees from the minimum over the follow-up period. The presence and timing of tether breakage were noted for each patient. A Kaplan-Meier survival analysis was performed to calculate expected tether breakage up to 36 months. χ2 analysis was performed to examine the relationship between tether breakage and reoperations. Independent t test was used to compare the average final Cobb angle between cohorts.
Results:
In total, 208 patients from 10 centers were included in our review. Radiographically identified tether breakage occurred in 75 patients (36%). The initial break occurred at or beyond 24 months in 66 patients (88%). Kaplan-Meier survival analysis estimated the cumulative rate of expected tether breakage to be 19% at 24 months, increasing to 50% at 36 months. Twenty-one patients (28%) with a radiographically identified tether breakage went on to require reoperation, with 9 patients (12%) requiring conversion to posterior spinal fusion. Patients with a radiographically identified tether breakage went on to require conversion to posterior spinal fusion more often than those patients without identified tether breakage (12% vs. 2%; P=0.004). The average major coronal curve angle at final follow-up was significantly larger for patients with radiographically identified tether breakage than for those without tether breakage (31 deg±12 deg vs. 26 deg±12 deg; P=0.002).
Conclusions:
The incidence of tether breakage in TAVBT is high, and it is expected to occur in 50% of patients by 36 months postoperatively.

Background:
Congenital talipes equinovarus (CTEV) is a relatively common pediatric orthopaedic disorder and a frequent cause of disability in adult populations. The Ponseti method has emerged as the generally preferred for treating children with CTEV. Strict adherence to this technique’s basic principles is critical to achieving favorable outcomes. In 2013, our institution decided that every case of pediatric CTEV would be treated by a single dedicated medical team. The present study aimed to compare the treatment outcomes of children with CTEV treated using the Ponseti method in period I (multiple surgeons) versus those in period II (single dedicated team).
Patients and Methods:
We included respectively the children with CTEV treated using the Ponseti method in Geneva University Hospitals’ pediatric units from 2007 to 2018. Data on patient demographics, clinical characteristics, and the treatment outcomes were collected. The primary outcome was the number of relapsed feet (treatment failure) after 3 years of follow-up. The 2 periods’ outcomes were compared using χ2 and independent Student t-tests. Run charts were used to report yearly rates of complications, minor and major recurrences, treatment failure, brace noncompliance, and feet that underwent tenotomy.
Results:
A total of 48 feet (32 patients) and 42 feet (29 patients) in periods I and II were included. The periods showed similar rates for participants’ characteristics. The run charts illustrated the overall improvements in treatment outcomes in period II. A total of 8 relapsed feet (5 patients) were reported, all during period I.
Conclusions:
Since all the pediatric CTEV patients at our institution began to be treated by a single dedicated medical team, we have observed a decrease in all recurrences and complications and an absence of treatment failure. These results highlight the importance of the continuity of care and strict adherence to the Ponseti method.

Objective:
Pediatric proximal humerus fractures (PHFx) are uncommon and makeup ~2% of all pediatric fractures. Traditionally, most cases are treated nonoperatively with closed reduction (CR) or immobilization with no reduction (INR) with excellent outcomes. Indications for CR without fixation remain unclear as immobilization in the position of reduction (shoulder abduction and external rotation) is not practical. We aim to determine the need for CR among adolescents with displaced PHFx treated nonoperatively.
Methods:
We conducted an IRB-approved prospective multicenter study involving 42 adolescents aged 10 to 16 years, treated for displaced PHFx across 6 institutions between 2018 and 2022. CR was performed under conscious sedation in the emergency department, with data collected during follow-up visits at 6 weeks and 3 months. Radiographic measurements, range of motion, and patient-reported outcomes, including the Patient-Reported Outcomes Measurement Information System Upper Extremity and Physical Function, Shoulder Pain and Disability Index, and QuickDash scores, were compared between the INR and CR groups.
Results:
Among 42 fractures, 23 (55%) were treated with INR and 19 (45%) with CR, followed by placement in a hanging arm cast or sling. Of the cases, 62% were high-energy injuries. Radiographic alignment and range of motion were similar between groups at preoperative, 6 weeks, and 3 months with no significant differences noted.
Patient-Reported Outcomes Measurement Information System Upper Extremity, Physical Function, QuickDash, and Shoulder Pain and Disability Index scores at 6 weeks and 3 months showed no significant differences between cohorts. Significant improvement was observed between 6 weeks and 3 months for every patient-reported outcome in both cohorts.
Conclusions:
For displaced PHFx treated nonoperatively, our data suggests INR has a similar radiographic and clinical outcome when compared with CR. Our results question the necessity of performing CR in this group of patients.

Background:
Total hip arthroplasty (THA) in teenagers is generally avoided. Nevertheless, recent THA procedures in a very young patient show improved functional outcomes and implant survival, resulting in lower revision rates. This review aims to present an overview of the available literature on THA in teenagers and to provide evidence to inform caregivers.
Methods:
In this systematic review, studies required a primary THA method and a teenage patient population. Studies must report at least one of the following outcome measures: functional outcomes, implant survival, and complications. In addition, demographic and surgical data were collected.
Results:
Sixteen studies were analyzed, including 2040 patients and 2379 hips, with an average 7.7-year follow-up. The mean patient age was 18 years, with an average revision rate of 11.7%. The overall average relative improvement of the 2 most frequently used patient-reported (functional) outcome measures were 84.3 and 92.3% at the latest follow-up. Prosthesis, or liner loosening, was the cause of revision in 50.2% of the cases. Loosening was the most frequent complication (14.8%), together with prosthesis/liner wear (14.8%). Cementless fixation (70.7%), ceramic-on-ceramic articulation (34.7%), and the posterior surgical approach (82.3%) were the most applied techniques.
Conclusions:
The functional outcomes after THA in teenagers improved at follow-up. The average revision rate is relatively high, especially in the pre-1995 studies, with post-1995 studies reporting similar revision rates to the adult patient group. Research to further improve implant survival as well as the ease of revisions in teenagers is needed.

Background:
Lower extremity valgus is a commonly described factor associated with patellofemoral instability (PFI) and, if identified before skeletal maturity, can be treated with guided growth. The prevalence of valgus alignment in the pediatric and adolescent PFI population is largely unknown.
Purpose:
The aim of this study was to report the prevalence of valgus alignment in adolescent patients presenting with PFI; with secondary assessment of high-grade valgus (zone II or III), coronal asymmetry, and associations of these findings with body mass index (BMI).
Study design:
A retrospective cohort study.
Methods:
A total of 279 consecutive patients (349 knees) with a diagnosis of PFI presenting to a single orthopedic pediatric sport medicine surgeon were identified. A retrospective chart review was performed to collect demographic and clinical data, chronologic and bone age, sex, BMI, mechanism of injury, and the presence of osteochondral fracture. Full-length standing hip-to-ankle alignment radiographs were graded for knee alignment mechanical zone utilizing standard linear femoral head center to talar center assessment. In addition, mechanical axis deviation, mechanical lateral distal femoral angle and medial proximal tibial angle (MPTA) were also calculated.
Results:
Mean patient age was 14.0±2.5 years. There were 162 (58.1%) females and mean BMI was 24.3±6.4. Seventy patients (25.1%) had bilateral PFI. Standing alignment radiographs were available for 81.4% of knees (n=284). Valgus alignment was present in 172 knees with PFI (60.6%). High-grade valgus, defined as zone 2 or greater, was present in 66 knees (23.3%). Overall, 48.9% had asymmetry of coronal alignment (n=139). The mean mechanical lateral distal femoral angle was 85.4±2.8 and the mean MPTA was 88.2±2.6. There was a greater MPTA in female patients (88.8±2.4 vs. 87.5±2.7, P<0.001). A higher BMI (24.87±6.95, P=0.03) was associated with valgus alignment.
Conclusions:
There is a high (60%) prevalence of lower extremity valgus in adolescent patients presenting with PFI, with nearly 1 in 4 presenting with high-grade valgus. The treatment team should be aware of this association as it may be an important consideration in the pediatric and adolescent PFI populations.

Objective:
Surgical treatment of congenital muscular torticollis (CMT) has been proven clinically effective in cases that fail to normalize after conservative treatment, but reports on self-reported outcome and quality of life have been scarce. This study aimed to assess health-related quality of life (HRQoL) in children, adolescents, and young adults undergoing surgical treatment for CMT, comparing HRQoL with clinical outcomes.
Methods:
We conducted a level 2 prospective observational study on a surgically treated CMT cohort at a single tertiary center. The surgeries focused on releasing all tightness, and the medial head was routinely elongated to preserve cosmetic function. Patients underwent rigorous pre/postoperative assessments and follow-up. A strict postoperative protocol entailing stretching, physiotherapy, and positional exercises was adhered to for a minimum of 6 months. The Cheng and Tang torticollis scoring system and PedsQLTM 4.0 generic core scales were used to evaluate clinical outcome and HRQoL, respectively.
Results:
The study included 31 patients, averaging 11.4 years. Significant improvements in range of motion, deformities, and overall subjective satisfaction were observed 2 years postoperatively. The Cheng and Tang score improved overall significantly from fair (9.9 points) to excellent (17.9 points) after 2 years (P<0.001). The oldest patients showed less improvement than the youngest ones, especially regarding craniofacial asymmetry (P=0.004). Patient PedsQL scores significantly improved 2 years post-surgery (P=0.040), with no discernable age differences.
Conclusion:
Our findings demonstrated significant improvements in both HRQoL and clinical outcomes after surgical treatment of CMT. The PedsQL score seemed sensitive to the clinical changes.

Background:
Low-energy lateral ankle injuries (Salter-Harris 1 distal fibula, distal fibula avulsion fractures, and radiograph-negative lateral ankle injuries) are common in pediatric patients. Patient-based outcomes for the 2 treatment options, short leg walking cast (CAST) and controlled ankle motion (CAM) boot, are unknown. This study aims to determine differences between 2 treatments of low-energy lateral ankle injuries in pediatric patients.
Methods:
A prospective, randomized controlled trial comparing the acute outcomes of CAST and CAM treatment for low-energy lateral ankle injuries in pediatric patients was completed. Patients were evaluated in-person at presentation and 4 weeks for ankle range of motion and Oxford foot and ankle score. A novel survey defining patient and parent satisfaction and time away from school/work was also completed. Treatment complications were documented. Patients were called at 8 weeks postinjury to determine other complications and the final time of return to sport. Mixed effects linear regression models evaluated change over time between the 2 treatment groups.
Results:
After 60 patients were enrolled, 28 patients in the CAST group and 27 patients in the CAM group completed the study. Males comprised 51% (28), with 38 (69%) patients identifying as Hispanic. The patient’s average age was 11.3±2.9 years and the average body mass index was 23.
At the 4-week evaluation, the CAM group had improved range of motion, higher satisfaction scores (5.26 CAM vs. 4.25 CAST, P<0.05), similar pain scores (0.32 CAST vs. 0.41 CAM, P=0.75), and lower complications (0.54/patient CAST vs. 0.04/patient CAM, P<0.0001) than the CAST group. Female patients had improved inversion with CAM treatment than males (P<0.05). Patients over age 12 in the CAST group had significantly decreased plantarflexion at week 4 (P=0.002). Improvement in Oxford scores was similar between the CAST and CAM groups between the initial presentation and 4 weeks, except for increased improvement in CAM group Oxford scores for difficulty running and symptoms with walking/walking. At the 8-week evaluation, patients in the CAST group had a higher rate of continued symptoms than the CAM group (15.4% vs. 0%)
Conclusions:
CAM boot treatment of low-energy lateral ankle injuries in pediatric patients results in improved results and lower complications than CAST treatment.

Background:
Congenital spinal anomalies represent a heterogeneous group of spinal deformities, of which only progressive or severe curves warrant surgical management. Only a limited number of studies have investigated the impact of surgery on the health-related quality of life and very limited data exists comparing these outcomes to healthy controls.
Methods:
A single surgeon series of 67 consecutive children with congenital scoliosis (mean age at surgery 8.0 y, range: 1.0 to 18.3 y, 28 girls) undergoing hemivertebrectomy (n = 34), instrumented spinal fusion (n = 20), or vertical expandable prosthetic titanium rib procedure (n = 13) with a mean follow-up of 5.8 years (range: 2 to 13 y). The comparison was made to age and sex-matched healthy controls. Outcome measures included the Scoliosis Research Society questionnaire both pre and postoperatively, radiographic outcomes, and complications.
Results:
The average major curve correction was significantly better in the hemivertebrectomy (60%) and instrumented spinal fusion (51%) than in the vertical expandable prosthetic titanium rib group (24%), respectively (P < 0.001). Complications were noted in 8 of 67 (12%) children, but all patients recovered fully during follow-up. Pain, self-image, and function domains improved numerically from preoperative to final follow-up, but the pain score was the only one with a statistically significant change (P = 0.033). The Scoliosis Research Society pain, self-image, and function domain scores remained at a significantly lower level at the final follow-up than in the healthy controls (P ≤ 0.05), while activity scores improved to a similar level.
Conclusions:
Surgery for congenital scoliosis improved angular spinal deformities with a reasonable risk of complications. Health-related quality of life outcomes improved from preoperative to final follow-up, but especially pain and function domains remained at a significantly lower level than in the age and sex-matched healthy controls.

Introduction:
Postoperative opioid prescriptions may confer a risk for subsequent opioid use disorders (OUDs). For many children, postoperative analgesia is often the first opioid exposure. The rates of anterior cruciate ligament (ACL) reconstruction in pediatric populations are rising. Here, we use an administrative claims database to describe opioid prescription patterns after ACL reconstruction and their effect on subsequent risk of OUD.
Methods:
Using International Classification of Diseases (ICD)-9, ICD-10, and CPT codes, we identified patients, with ages 10 to 18, undergoing primary ACL reconstruction between 2014 and 2016 with minimum 1 year follow-up in the Optum Clinformatics Data Mart, which is a nationally representative administrative claims database. Demographic variables and prescription patterns (in morphine milligram equivalents [MMEs]) were analyzed using univariate tests and multivariable logistic regression to determine any potential association with the appearance of anew an ICD-9 or ICD-10 code for OUD within 1 year of the initial procedure.
Results:
A total of 4459 cases were included and 29 (0.7%) of these patients were diagnosed with an OUD within 1 year of surgery. Upon univariate analysis, opioid represcriptions within 6 weeks were significantly more common among patients with OUD; 27.6% vs. 9.7% of patients that did not develop a new diagnosis of OUD (P=0.005). Multivariable logistic regression indicated an independent significant relationship between total MMEs initially prescribed and the odds of a subsequent OUD diagnosis: for each additional 100 MMEs prescribed in total, the odds of OUD increased by 13% (P=0.002). Patients with a represcription within 6 weeks of surgery had an average increase in the odds of OUD by 161% (P=0.027).
Conclusions:
In this cohort of patient ages 10 to 18 undergoing primary isolated ACL reconstruction, we found substantial variability in opiate prescribing patterns and higher initial opioid prescription volume, as well as opioid represcription within 6 weeks were predictive of the subsequent development of OUD.

Physician extenders and advanced practice providers (APPs) are now common in most adult and pediatric orthopaedic clinics and practices. Their utilization, with physician leadership, can improve patient care, patient satisfaction, and physician satisfaction and work/life balance in addition to having financial benefits. Physician extenders can include scribes, certified athletic trainers, and registered nurses, while APPs include nurse practitioners and physician assistants/associates. Different pediatric orthopaedic practices or divisions within a department might benefit from different physician extenders or APPs based on particular skill sets and licensed abilities. This article will review each of the physician extender and APP health care professionals regarding their training, salaries, background, specific skill sets, and scope of practice. While other physician extenders such as medical assistants, cast technicians, and orthotists/prosthetists have important roles in day-to-day clinical care, they will not be reviewed in this article. In addition, medical trainees, including medical students, residents, fellows, and APP students, have a unique position within some academic clinics but will also not be reviewed in this article. With the many different local, state, and national regulations, a careful understanding of the physician extender and APP roles will help clinicians optimize their ability to improve patient care.

Self-confidence is one of the attributes often assigned to surgeons, but surgeons do not always feel self-confident in the operating room. A lack of confidence may lead to poor performance for both the surgeon and the surgical team. The ideal qualities of a self-confident surgeon, barriers to achieving confidence and strategies for becoming a more confident surgeon and leader in the operating room are outlined in this chapter.

Background:
Congenital vertebral anomalies are a heterogeneous group of diagnoses, and studies on their epidemiology are sparse. Our aim was to investigate the national prevalence and mortality of these anomalies, and to identify associated anomalies.
Methods:
We conducted a population-based nationwide register study and identified all cases with congenital vertebral anomalies in the Finnish Register of Congenital Malformations from 1997 to 2016 including live births, stillbirths, and elective terminations of pregnancy because of major fetal anomalies. Cases were categorized based on the recorded diagnoses, associated major anomalies were analyzed, and prevalence and infant mortality were calculated.
Results:
We identified 255 cases of congenital vertebral anomalies. Of these, 92 (36%) were diagnosed with formation defects, 18 (7.1%) with segmentation defects, and 145 (57%) had mixed vertebral anomalies. Live birth prevalence was 1.89 per 10,000, and total prevalence was 2.20/10,000, with a significantly increasing trend over time (P<0.001). Overall infant mortality was 8.2% (18/219); 3.5% (3/86) in patients with formation defects, 5.6% (1/18) in segmentation defects, and 12.2% (14/115) in mixed vertebral anomalies (P=0.06). Co-occurring anomalies and syndromes were associated with increased mortality, P=0.006. Majority of the cases (82%) were associated with other major anomalies affecting most often the heart, limbs, and digestive system.
Conclusions:
In conclusion, the prevalence of congenital vertebral anomalies is increasing significantly in Finnish registers. Detailed and systematic examination is warranted in this patient population to identify underlying comorbidities as the majority of cases are associated with congenital major anomalies.

Background:
Slip progression after in situ fixation of slipped capital femoral epiphysis (SCFE) has been reported as occurring in up to 20% of patients. We review SCFE treated with in situ single screw fixation performed at 2 hospitals over a 15-year period to determine the factors associated with slip progression.
Methods:
This case-control study reviews SCFE treated with in situ single cannulated screw fixation with minimum follow up of 1 year and full closure of the affected physis. Slip progression (failure) was defined as worsening of the Southwick slip angle of 10 or more degrees or revision surgery for symptomatic slip progression. Univariate and multivariate analyses were performed comparing success and failure groups for patient characteristics, screw type and position, and radiographic measurements.
Results:
Ninety three patients with 108 slips met all criteria, with 15 hips (14%) classified as having slip progression (failure). All failures had 3 threads or fewer across the physis. Five hips had 2 threads across the physis, and 4 of the 5 were classified as failures. Lower modified Oxford bone scores were found in the failure group, though the difference was small (0.9, P=0.013). Failure was also associated with partially threaded screws (P=0.001). Failed hips were associated with lower initial Southwick angles (32.8 degrees) than successful hips (40.4 degrees) (P=0.047). In the stepwise model for multivariate regression, 4 factors were identified as significant, with lower initial number of threads (P<0.0001), mild initial Southwick category (P=0.0050), male sex (P=0.0061), and partially threaded screw type (P=0.0116) predicting failure.
Conclusion:
This study is the largest to date evaluating risk factors for slip progression after SCFE fixation, and the first to consider revision surgery for symptomatic slip progression. For stable SCFE, we demonstrate that 4 threads across the physis with a fully threaded screw of 6.5 mm diameter or greater was sufficient to avoid slip progression. We provide a risk stratification for progression of slip showing that in some cases 3 threads across the physis may be sufficient.

Background:
When operative treatment is indicated, tibial spine fractures can be successfully managed with open or arthroscopic reduction and internal fixation (ARIF). The purpose of the study is to evaluate short-term treatment outcomes of tibial spine fractures in patients treated with both open and arthroscopic fracture reduction.
Methods:
We performed an Institutional Review Board (IRB)-approved retrospective cohort study of pediatric tibial spine fractures presenting between January 1, 2000 and January 31, 2019 at 10 institutions. Patients were categorized into 2 cohorts based on treatment: ARIF and open reduction and internal fixation (ORIF). Short-term surgical outcomes, the incidence of concomitant injuries, and surgeon demographics were compared between groups.
Results:
There were 477 patients with tibial spine fractures who met inclusion criteria, 420 of whom (88.1%) were treated with ARIF, while 57 (11.9%) were treated with ORIF. Average follow-up was 1.12 years. Patients treated with ARIF were more likely to have an identified concomitant injury (41.4%) compared with those treated with ORIF (24.6%, P=0.021). Most concomitant injuries (74.5%) were treated with intervention. The most common treatment complications included arthrofibrosis (6.9% in ARIF patients, 7.0% in ORIF patients, P=1.00) and subsequent anterior cruciate ligament injury (2.1% in ARIF patients and 3.5% in ORIF, P=0.86). The rate of short-term complications, return to the operating room, and failure to return to full range of motion were similar between treatment groups. Twenty surgeons with sports subspecialty training completed 85.0% of ARIF cases; the remaining 15.0% were performed by 12 surgeons without additional sports training. The majority (56.1%) of ORIF cases were completed by 14 surgeons without sports subspecialty training.
Conclusion:
This study demonstrated no difference in outcomes or nonunion following ARIF or ORIF, with a significantly higher rate of concomitant injuries identified in patients treated with ARIF. The majority of identified concomitant injuries were treated with surgical intervention. Extensive surgical evaluation or pretreatment magnetic resonance imaging should be considered in the workup of tibial spine fractures to increase concomitant injury identification.

Introduction:
Identifying risk factors associated with developmental dysplasia of the hip (DDH) is essential for early diagnosis and treatment. Breech presentation is a major DDH risk factor, possibly because of crowding of the fetus within the uterus. In multifetal pregnancy, fetuses are generally smaller than singletons, which may obscure the effect of breech presentation on fetal hips. Only a few studies have investigated the occurrence of DDH in multifetal pregnancies. In this study, we aimed to evaluate whether the breech presentation is a major risk factor of DDH in twin pregnancies.
Methods:
This retrospective study included 491 consecutive live births (after 23+0 weeks gestation) delivered through cesarean section with at least 1 baby with noncephalic presentation in single or twin pregnancies from April 2013 to October 2018. We analyzed the incidence of DDH and its associated factors, including sex, breech, and multifetal pregnancy, with a generalized linear mixed model.
Results:
The incidence of DDH was 12.5% in singleton with breech presentation, 9.8% in twin-breech presentation, and 0.7% in twin-cephalic presentation. Multivariate analysis showed that singleton-breech presentation (P=0.003), twin-breech presentation (P=0.003), and female sex (P=0.008) were independent risk factors for DDH.
Conclusion:
Breech presentation is an independent risk factor for DDH in twin pregnancies, although twin pregnancy itself is not an independent risk factor for DDH.

Background:
While management recommendations for distal radius fractures in both young and skeletally mature patients have been generally well-established, controversy still exists regarding optimal management in adolescent patients approaching skeletal maturity. Thus, the goal of this review is to analyze relevant literature and provide expert recommendations regarding the management of distal radius fractures in this patient population.
Methods:
A PubMed search was performed to identify literature pertaining to distal radius fractures in adolescent patients, defined as 11 to 14 years in girls and 13 to 15 years in boys. Relevant articles were selected and summarized.
Results:
Distal radius fractures demonstrate significant potential for remodeling of angular deformity and bayonet apposition, even in patients older than 12 years of age. Rotational forearm range of motion and functional outcomes are acceptable with up to 15 degrees of residual angulation. Closed reduction and percutaneous pinning reduces fracture redisplacement but has a high associated complication rate. There is no literature comparing plate versus pin fixation of distal radius fractures in the pediatric population, but in adults plate fixation is associated with higher cost with no improvement in long-term functional outcomes.
Conclusions:
Remodeling can still be expected to occur in adolescent patients, and even with residual deformity functional outcomes after distal radius fractures are excellent. Up to 15 degrees of residual angulation can be accepted before considering operative management. Smooth pins should be considered over plates as first-line operative management for unstable fractures that fail nonoperative treatment.

Introduction:
The transition from pediatric to adolescent fractures can lead to uncertainty on what level of surgical correction is warranted as remodeling is limited in these older patients.
Discussion:
Adolescent diaphyseal radial shaft fractures present several unique challenges; the radial bow must be restored to preserve forearm rotation and there are several clinical scenarios where plating, even in the skeletally immature child, is strongly recommended and will have more reliable results over flexible intramedullary nails. In addition, judging how much angulation, rotation, and displacement will remodel in the older child can be a challenging decision, even for experienced pediatric orthopaedists.
Conclusion:
This overview discusses parameters for acceptable alignment in these fractures, when surgical fixation should be considered, and circumstances where plating should be considered over flexible nails.

Background:
Distal radius physeal bar with associated growth arrest can occur because of fractures, ischemia, infection, radiation, tumor, blood dyscrasias, and repetitive stress injuries. The age of the patient as well as the size, shape, and location of the bony bridge determines the deformity and associated pathology that will develop.
Methods:
A search of the English literature was performed using PubMed and multiple search terms to identify manuscripts dealing with the evaluation and treatment of distal radius physeal bars and ulnar overgrowth. Single case reports and level V studies were excluded.
Results:
Manuscripts evaluating distal radial physeal bars and their management were identified. A growth discrepancy between the radius and ulna can lead to distal radioulnar joint instability, ulnar impaction, and degenerative changes in the carpus and triangular fibrocartilage complex. Advanced imaging aids in the evaluation and mapping of a physeal bar. Treatment options for distal radius physeal bars include observation, bar resection±interposition, epiphysiodeses of the ulna±completion epiphysiodesis of the radius, ulnar shortening osteotomy±diagnostic arthroscopy to manage associated triangular fibrocartilage complex pathology, radius osteotomy, and distraction osteogenesis.
Conclusions:
Decision-making when presented with a distal radius physeal bar is multifactorial and should incorporate the age and remaining growth potential of the patient, the size and location of the bar, and patient and family expectations.

Introduction:
Adolescents undergoing pediatric orthopaedic surgery typically experience an uncomplicated postoperative course. However, adolescence represents a unique transition period from pediatric to adult physiology. As a result, the astute pediatric orthopaedic surgeon will be aware of unique medical and social scenarios which are relevant to adolescents during the perioperative course including the risk of venous thromboembolism (VTE), prevalence of mental health conditions, and rising use of electronic cigarettes or “vaping” to consume nicotine and cannibas.
Discussion:
Adolescents are at a greater risk of VTE after pediatric orthopaedic surgery. In particular, adolescent females with a family history of blood clotting disorders and those with a change in mobility after surgery should be considered for prophylaxis. The prevalence of adolescent mental health conditions including anxiety, depression, and behavioral issues is increasing in the United States. Higher levels of preoperative anxiety and the presence of mental health pathology are associated with slower recovery, higher levels of postoperative pain, and the increased likelihood for chronic pain. Several quick screening instruments are available to assess adolescents for preoperative anxiety risk, including the Visual Analogue Scale for Anxiety or the Amsterdam Perioperative Anxiety Information Scale. Unfortunately, electronic cigarettes have become increasingly popular for the consumption of nicotine and cannabis among adolescents. Preoperative use of combustive cigarettes (nicotine/cannabis) represents perioperative risks for induction/anesthesia, postoperative pain, and analgesia requirements and issues with delayed wound and fracture healing.
Conclusions:
VTE, underlying mental health conditions, and usage of nicotine and cannabis are clear detriments to the recovery and healing of adolescent patients following orthopaedic surgery. Therefore, standardized screening for adolescents before orthopaedic surgery is indicated to identify perioperative risk factors which have negative impacts on functional outcomes.

Introduction:
Tibial shaft fractures are common injuries in the adolescent age group. Potential complications from the injury or treatment include infection, implant migration, neurovascular injury, compartment syndrome, malunion, or nonunion.
Methods:
Published literature was reviewed to identify studies which describe the management options, complications, and outcome of tibial shaft fractures in adolescents.
Results:
Acceptable alignment parameters for tibial shaft fractures have been defined. Operative indications include open fractures and other severe soft tissue injuries, vascular injury, compartment syndrome, ipsilateral femoral fractures, and polytrauma. Relative indications for operative treatment are patient/family preference or morbid obesity. Closed reduction and cast immobilization necessitates radiographic observation for loss of reduction over the first 3 weeks. Cast change/wedging or conversion to operative management may be required in 25% to 40%. Flexible nailing provides relative fracture stability while avoiding the proximal tibial physis, but the fracture will still benefit from postoperative immobilization. Rigid nailing provides greater fracture stability and allows early weight bearing but violates the proximal tibial physis. Plate and screw osteosynthesis provide stable anatomic reduction, but there are concerns with delayed union and wound complications related to the dissection. External fixation is an excellent strategy for tibia fractures associated with complex wounds but also requires observation for loss of reduction.
Discussion and Conclusions:
The majority of adolescent tibia shaft fractures can be successfully managed with closed reduction and cast immobilization. Unstable fractures that have failed cast treatment should be treated operatively. Flexible intramedullary nailing, rigid intramedullary nailing, plate and screw osteosynthesis, and external fixation are acceptable treatment options that may be considered for an individual patient depending upon the clinical scenario.

Background:
The natural history of traumatic glenohumeral dislocation is well-established in young adults, but it is less clear in pediatric patients. We aimed to determine the rate of recurrent instability and medium-term functional outcome following shoulder dislocation in patients aged 14 years or younger.
Methods:
All patients aged 14 years or younger who sustained a glenohumeral dislocation from 2008 to 2019 presenting to our regional health-board were identified. Patients who had subluxations associated with generalized laxity were excluded. Data was collected regarding further dislocations, stabilization surgery, sporting activity and patient-reported outcomes using the Western Ontario Shoulder Instability (WOSI) Index and Quick Disabilities of the Arm, Shoulder, and Hand score.
Results:
Forty-one patients with a radiologically confirmed traumatic glenohumeral dislocation were suitable for study inclusion [mean age at injury 12.3 y (range: 7.2 to 14.0 y), male sex 29 (70.7%), median 7.9 y follow-up]. The incidence rate of pediatric glenohumeral dislocation was 2.5 cases per 100,000 population (aged 0 to 14 y) per year. Recurrent dislocation occurred in 43.9% (n=18/41) at a median time of 14.7 months postinjury (range: 1 to 54 mo). Skeletal maturity was associated with significantly higher proportion of recurrent instability (immature 6/24 vs. mature 12/17, P=0.01). One in 5 patients required surgical intervention for recurrent instability [mean 8 (range: 1 to 14) dislocations before surgery]. Twenty-eight patients had completed outcome questionnaires. The median modified WOSI score was 87.1% [270 (interquartile range: 65 to 795)] and the median Quick Disabilities of the Arm, Shoulder, and Hand score was 3.4 (interquartile range: 0 to 9.7). Recurrent shoulder instability was significantly associated with poorer WOSI score (unstable 71.4% vs. stable 94.3%, 95% confidence interval of the difference 6.2-36.9, P=0.04).
Conclusions:
Traumatic glenohumeral dislocation in patients aged 14 years or younger occurs rarely but is not a benign event. One in 2 patients experienced recurrent dislocation and 1 in 5 ultimately underwent surgical stabilization.

Introduction:
The ability for teams to work together in a coordinated manner may be where the greatest improvements in health care occur in the next generation. To perform at the highest level there are several key principles that all teams must have no matter what playing field they are on, including health care.
Methods:
Several resources were used to identify the challenges we face in health care with respect to the delivery of quality care, improving outcomes and decreasing complications. A search of the lay press and scientific literature was evaluated to identify those key elements that lead to improvements in team performance. In addition, personal observations were accumulated with time and examples of strategies used at home institutions were identified.
Results:
The teams in our pediatric orthopaedic practices are many and include those in the clinic, the operating room, research, and our administrative office. The Institute of Medicine, in their influential article in 1999, defined the alarming rates of complications/harm occurring in the US health care system. In response, the Agency for Healthcare Research and Quality (AHRQ) and the Department of Defense (DOD) collaborated to create the Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) in 2006. This was implemented in military facilities and later civilian hospital settings with varied success in civilian hospital settings.
Discussion:
They defined key principles based around team structure, communication, leadership, situation monitoring, and mutual support. Other important foundational attributes of a successful team include identifying the vision of the team, hiring top-talent in the form of hard and soft skills, having open communication, being goal-focused, practicing accountability, and having an organized team. We can look to excellent examples in medicine, business, and sports to see where and how high-functioning teams have existed and to learn from them to implement similar successful teams.
Conclusions:
Team performance is a function of talented members who share a common vision, who have the opportunity to voice their thoughts/opinions, and have the ability to be accountable to each other. Surgeons need to lead by example, and provide each member of the team an opportunity to contribute in a meaningful way which ultimately will improve the lives of the patients we are honored to care for.

Background:
Annual rankings by US News and World Report are a widely utilized metric by both health care leaders and patients. One longstanding measure is time to treatment of femur shaft fractures. Hospitals able to provide at least 80% of pediatric patients with an operating room start time within 18 hours of admission to the emergency department score better as part of the overall pediatric orthopaedic ranking. Therefore, it is important to determine whether the 18-hour treatment time for pediatric femur shaft fractures is a clinically meaningful metric.
Methods:
A retrospective review of clinical outcomes of 174 pediatric patients (aged below 16 y) with isolated femur shaft fractures (Injury Severity Score=9) was conducted from 1997 to 2017 at a single level I pediatric trauma center. The 2 comparison groups were patients receiving fracture reduction within 18 hours of emergency department admission (N=87) or >18 hours (N=87).
Results:
Patient, injury, and surgical characteristics were similar between the 2 groups. Both groups had a similar mean age (treatment <18 h=7.5 y; treatment >18 h=8.1 y). Patients who received treatment within 18 hours were more often immobilized postoperatively (70.1% vs. 53.5%; P=0.0362) and had a shorter median hospital length of stay (2 vs. 3 d; P=0.0047). There were no statistically significant differences in any outcomes including surgical site infection, time to weight-bearing (treatment <18 h mean=48.1 d vs. 52.5 d), time to complete radiographic fracture healing (treatment <18 h mean=258.9 d vs. 232.0 d), decreased range of motion, genu varus/valgus, limb length discrepancy, loss of reduction, or persistent pain.
Conclusions:
Treatment of pediatric femur shaft fractures within 18 hours does not impact clinical outcomes. National quality measures should therefore use evidence-based metrics to help improve the standard of care.

Background:
Increased participation in youth sports is associated with increased rates of anterior cruciate ligament (ACL) tears in the skeletally immature. Historically, ACL reconstruction was avoided in the skeletally immature, or delayed until skeletal maturity, to avoid physeal injury and growth disturbance. Current practices and meta-analyses support early ACL reconstruction in some groups, to allow for return to activities and to avoid delayed cartilage/meniscus injury.
Purpose:
The purpose of this article was to report on the natural history of ACL injuries in the skeletally immature.
Methods:
A review of published literature on pediatric, skeletally immature ACL tears and conservative, nonoperative treatment was conducted via Pubmed articles published from 1970 to 2018. The search criteria included the key terms “anterior cruciate ligament,” “pediatric” and/or “adolescent,” and “conservative” and/or “nonoperative treatment.” A PRISMA workflow was used to narrow down the articles to those relevant to our analysis and available in full text format.
Results:
Multiple articles on the nonoperative treatment of the ACL showed secondary meniscal and cartilage damage at the time of follow-up. Some articles showed no difference between the rates of secondary injuries between the surgical and nonsurgical treatment groups; however, the nonsurgical treatment groups were often on significant activity modification. Some articles concluded that nonoperative treatment of the ACL tear may be appropriate in low risk, lower level activity patients, and those that will comply with activity restrictions. Even with bracing and PT programs, active athletes treated without surgery appear to have a concerning rate of secondary meniscus injury after the primary ACL injury event.
Conclusions:
The natural history of the ACL tear shows nonoperative treatment for the skeletally immature may be a viable treatment pathway for those who are able to comply with the physical activity restrictions. For the general population of young, active adolescents, an ACL injury treated nonoperatively often leads to secondary meniscal and/or cartilage damage, which may lead to knee degeneration and functional instability.

Introduction:
Adolescent idiopathic Scoliosis (AIS) affects 2% to 3% of the population of which only 0.3% to 0.5% of affected patients will have a curvature of >20 degrees, the curve magnitude at which treatment is generally recommended. For AIS the current natural history data is limited and most of the information comes from a small body of literature from the University of Iowa.
Methods:
The Iowa natural history studies began as retrospective reviews but beginning in 1976, the cohort was followed prospectively. Outcomes assessed in this group of patients included; mortality, pulmonary function, pregnancy-(effect of pregnancy on scoliosis and the effect of scoliosis on pregnancy), radiographic, curve progression, and osteoarthritis. In addition, validated questionnaires were used to evaluate back pain, pulmonary symptoms, general function, depression, and body image.
Results:
Patients with untreated AIS can function well as adults, become employed, get married, have children, and grow to become active older adults. Unfortunately, untreated scoliosis may lead to increased back pain and pulmonary symptoms for patients with large thoracic curves. Patients with untreated AIS can also develop substantial deformity, and the cosmetic aspect of this condition cannot be disregarded.
Conclusions:
The summary findings of this unique lifetime natural history of AIS patients provides patients and parents a solid evidence base upon which to make informed decisions.

Background:
The long-term effects of small limb length discrepancies have been poorly documented in the literature. References to low back pain, hip pathology, knee pathology, and foot problems abound in the popular literature. Health care providers frequently recommend the use of lifts for structural and functional limb length discrepancies, yet the natural history of limb length inequality as well as the effectiveness of treatments that may be recommended are obscure. The purpose of this paper is to document and evaluate the literature associated with small limb length discrepancies.
Methods:
A search of the English literature was carried out using PubMed to identify papers dealing with the effects of limb length discrepancies. Papers reporting only expert opinion or case reports were excluded.
Results:
Papers dealing with the natural history of limb length discrepancy as well as studies in which gait analysis was performed in patients with limb length discrepancy were identified. Only 10% of the population has exactly equal lower limb lengths. Approximately 90% of the population has a limb length discrepancy <1.0 cm. Hip and knee pathology is present in an increased number of patients with limb length discrepancies over 5 mm. Hip pathology is more often present in the long leg, knee pathology has been reported in various studies to be more common in either the long or short leg. Low back problems seem to be more common on the short side in patients with limb length discrepancies. A number of different compensatory mechanisms for limb length discrepancy have been identified during gait analysis.
Conclusions:
There seems to be a consensus that limb length discrepancies >2.0 cm are frequently a problem. There is some evidence that limb length discrepancies as little as 5 mm can lead to long-term pathology.

Background:
In order to determine whether treatments are effective in the treatment of meniscus tears, it is first necessary to understand the natural history of meniscus tears. The purpose of this paper is to review the literature to ascertain the natural history of meniscus tears in children and adolescents.
Methods:
A search of the Pubmed and Embase databases was performed using the search terms “meniscus tears,” “natural history of meniscus tears,” “knee meniscus,” “discoid meniscus,” and “natural history of discoid meniscus tears.”
Results:
A total of 2567 articles on meniscus tears, 28 articles on natural history of meniscus tears, 8065 articles on “menisci,” 396 articles on “discoid meniscus,” and only 2 on the “natural history of discoid meniscus” were found. After reviewing the titles of these articles and reviewing the abstracts of 237 articles, it was clear that there was little true long-term natural history data of untreated meniscus tears nor whether treating meniscus tears altered the natural history. Twenty-five articles were chosen as there was some mention of natural history in their studies.
Conclusions:
There are few long-term data on untreated meniscal tears or discoid meniscus, or tears in children and adolescents. The literature suggests that there is a higher incidence of chondral injury and subsequent osteoarthritis, but there are many confounding variables which are not controlled for in these relatively short-term papers.

Background:
Early-onset scoliosis (EOS) is defined as the diagnosis of a spinal deformity before the age of 5 years. It can be divided into idiopathic, neuromuscular/syndromic, and congenital etiologies.
Methods:
The literature on the natural history of EOS was summarized.
Results:
The natural history varies with the etiology of EOS. Idiopathic curves may benefit from early serial casting. The natural history of neuromuscular and syndromic scoliosis is highly dependent on the natural history of the underlying disorder. Congenital scoliosis has a variable prognosis depending on the location and extent of the congenital malformations.
Conclusions:
Treatment of children with EOS is customized to the particular disorder. While lack of treatment has been shown to lead to increased mortality, extensive early definitive fusion may lead to thoracic insufficiency. Delaying definitive surgery and the use of growing instrumentation may provide benefit in maintaining pulmonary health.
Clinical Relevance:
Potential disturbance of growth must be considered in the treatment of young children with scoliosis.

Optimal clinical decision making and surgical management of hip dysplasia in children with cerebral palsy (CP) requires an understanding of the underlying pathophysiology (pathomechanics and pathoanatomy), incidence, and natural history. The incidence of hip dysplasia in children with CP is directly related to the degree of motor impairment. A subluxated or dislocated hip in a child with CP can compromise the quality of life for both the child and their caregivers. The goal of this article is to highlight the events over the last 25 years that have had the greatest impact on the management of hip dysplasia in children with CP. It is my opinion that the 2 most significant advances during this time have been the development of a classification system based upon motor impairment (the Gross Motor Function Classification System), and the development of surveillance programs for hip dysplasia in children with CP. This article will contrast neuromuscular hip dysplasia with developmental dysplasia of the hip. It will be shown how the development and utilization of the Gross Motor Function Classification System has contributed to our understanding of the epidemiology and natural history of hip dysplasia in children with CP, and to the assessment of outcomes following surgical management. The impact of hip surveillance programs on early soft tissue surgeries, skeletal hip reconstructions, and the incidence of hip dislocations and salvage surgeries will be reviewed. Challenges in the implementation of hip surveillance programs in resource poor and decentralized health care delivery systems will be considered, and innovative approaches identified.

Background:
Loeys-Dietz syndrome (LDS) is a genetic connective tissue disorder. We sought to determine the incidence of scoliosis in patients with LDS, characterize the spectrum of spinal deformity, determine the results of bracing and surgery, and define surgical complications.
Methods:
Patients were selected from our institution’s database of 183 patients with LDS. Imaging measurements were performed for 141 patients whose records permitted spinal evaluation. Deformity changes and complications after intervention were recorded for patients who underwent bracing or surgery, and associations were tested using Student t tests (significance, P<0.05).
Results:
Eighty-eight of 141 (62%) patients with LDS had scoliosis, with main thoracic and thoracolumbar curves being most common. Fifteen patients were braced (mean age, 9±3 y) for a mean of 2.3 years. They had a mean postbracing curve progression of 12±21 degrees (5±9 deg./y). There were no significant differences in age, sex, curve type, or prebracing curve magnitude between successfully braced (n=4) and unsuccessfully braced (n=11) patients (P>0.05). Nine patients, (mean age, 12±3 y), underwent 24 surgical procedures (16 growing rod procedures, 8 fusions). Mean curve corrections were 61% for growing rods and 73% for fusions. Associated blood loss for these procedures was 400 mL and 1293 mL, respectively, and normalized blood loss for fusion was 2.34 mL/kg/level. Fifteen of 24 surgical procedures involved complications (63%), including cerebrospinal fluid leaks (n=7) and blood loss >20% of estimated total blood volume (n=11).
Conclusions:
Scoliosis was present in 62% of our sample of LDS patients. Bracing did not halt curves in 11 of 15 patients, whose curves progressed >5 degrees or to >50 degrees by completion of bracing. At latest follow-up, 47% of the braced patients had undergone surgery after prior bracing attempts. The high blood loss associated with these operations is believed to be related to vascular fragility in patients with LDS.

Although cubitus varus has been regarded as a purely cosmetic problem in the pediatric population, symptomatic elbow instability, and ulnar neuropathy from the mechanical axis malalignment have been reported in adults. This overview discusses the biomechanical axis disruption that leads to soft tissue and morphologic bony alterations in the elbow and offers a compelling argument for corrective osteotomy to treat pediatric cubitus varus.

Although the core principles of managing infantile Blount disease generally remain unchanged, treatment modalities have evolved over the years. Consensus has yet to be reached regarding the efficacy of bracing. Children with Blount disease commonly have advanced bone age, which may impact the timing and magnitude of (over) correction of angular deformity. Techniques of growth modulation, based on the tension band principle, continue to gain popularity. Although there are limited reports in the last decade on proximal tibial osteotomy for this developmental disorder, both acute and gradual correction remain viable treatment options in the appropriate setting. In certain older children (>7 y old) with advanced stages of the disease, a medial hemiplateau elevation combined with lateral proximal tibial hemiepiphysiodesis may be needed to address the epiphyseal deformity. Given the possibility of unpredictable proximal tibial physeal activity, all children with Blount disease should be followed at regular intervals till skeletal maturity. To provide sufficient granularity for pooled analyses and help establish evidence-based clinical guidelines, standardization of reporting clinical outcomes among children with Blount disease is encouraged.

Pediatric ankle injuries are common, especially in athletes; however, the incidence of syndesmosis injuries in children has been scarcely reported. Injuries to the ankle syndesmosis, termed “high ankle sprains,” can affect high-level and recreational athletes and have been related to delayed return to play, persistent pain, and adult injuries have been associated with long-term disability. Syndesmotic injuries do occur in children, especially those who participate in sports that involve cutting and pivoting (football, soccer) or sports with rigid immobilization of the ankle (skiing, hockey). Unstable pediatric syndesmosis injuries requiring surgical fixation are often associated with concomitant fibular fracture in skeletally mature children. Physician vigilance and careful clinical examination coupled with appropriate radiographs can determine the extent of the injury in the majority of circumstances.

Despite the increasing popularity of operative treatment in adolescent tibia fractures, casting remains a viable first-line treatment. Because the selection bias in published reports does not allow direct comparison between casting and flexible nail treatment of closed pediatric tibia fractures, it is unclear whether flexible nailing offers any advantages over casting. This overview discusses parameters of acceptable alignment, indications, techniques for successful reduction and casting, subsequent inpatient and outpatient management including wedging of casted tibia fractures, expected outcomes, and comparison of casting with flexible nailing. As with any orthopaedic procedure, careful attention to patient selection, indications, and detail facilitates successful cast treatment in this older pediatric population.

Despite advances in patient safety since the landmark Institute of Medicine Report To Err is Human was published, adverse events and medical errors remain a persistent problem throughout health care. Safety experts have examined the practices in high-risk industries that maintain outstanding safety records for strategies to address the problem. Those efforts led to the development of Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS), a patient safety program that incorporates the principles of crew resource management and teamwork successfully used by industry into the health care setting. Evidence supports that the knowledge, skills, and attitudes, that comprise the core of TeamSTEPPS program, can improve safety and outcomes when used by members of the health care team. Successful implementation should assist the transition of health care workers from functioning as individual experts to performing as members of expert teams.

Surgical hip dislocation (SHD) is a versatile approach used to address both intra-articular and extra-articular pathology around the hip joint in both pediatric and adult patients. It allows anterior dislocation of the femoral head for direct visualization of the hip joint while preserving femoral head vascularity and minimizing trauma to the abductor musculature. Previously described indications for SHD include femoroacetabular impingement, deformity resulting from Legg-Calve-Perthes disease, slipped capital femoral epiphysis, periarticular trauma, benign lesions of the hip joint, and osteochondral lesions. In this review, we will describe current surgical techniques, indications, and clinical outcomes for SHD.

Background:
Much attention has been given to the relationship between various training factors and athletic injuries, but no study has examined the impact of sleep deprivation on injury rates in young athletes. Information about sleep practices was gathered as part of a study designed to correlate various training practices with the risk of injury in adolescent athletes.
Methods:
Informed consent for participation in an online survey of training practices and a review of injury records was obtained from 160 student athletes at a combined middle/high school (grades 7 to 12) and from their parents. Online surveys were completed by 112 adolescent athletes (70% completion rate), including 54 male and 58 female athletes with a mean age of 15 years (SD=1.5; range, 12 to 18 y). The students’ responses were then correlated with data obtained from a retrospective review of injury records maintained by the school’s athletic department.
Results:
Multivariate analysis showed that hours of sleep per night and the grade in school were the best independent predictors of injury. Athletes who slept on average <8 hours per night were 1.7 times (95% confidence interval, 1.0-3.0; P=0.04) more likely to have had an injury compared with athletes who slept for ≥8 hours. For each additional grade in school, the athletes were 1.4 times more likely to have had an injury (95% confidence interval, 1.2-1.6; P<0.001).
Conclusion:
Sleep deprivation and increasing grade in school appear to be associated with injuries in an adolescent athletic population. Encouraging young athletes to get optimal amounts of sleep may help protect them against athletic injuries.
Level of Evidence:
Level III.

This article reviews the current best evidence for musculoskeletal interventions in children with ambulatory cerebral palsy (CP). The effectiveness of interventions in CP must first consider what CP and its associated pathophysiology are and take into account the heterogeneity and natural history of CP to put definitions of “effectiveness” into perspective. This article reviews the current standards of the definition and classification of CP, discusses the natural history and specific goals for the management of ambulatory CP, as well as the outcome measures available to measure these goals. The current best evidence of effectiveness is reviewed for specific interventions in children with ambulatory CP including spasticity management with botulinum toxin A injections and selective dorsal rhizotomy; multilevel orthopaedic surgery to address contractures and bony deformity; and the role of gait analysis for surgical decision-making before orthopaedic surgery.

Physeal fractures of the distal tibia and fibula are common and can be seen at any age, although most are seen in the adolescent. An understanding of the unique anatomy of the skeletally immature ankle in relation to the mechanism of injury will help one understand the injury patterns seen in this population. A thorough clinical exam is critical to the diagnosis and treatment of these injuries and the avoidance of potentially catastrophic complications. Nondisplaced physeal fractures of the distal tibia and fibula can be safely treated nonoperatively. Displaced fractures should undergo a gentle reduction with appropriate anesthesia while multiple reduction attempts should be avoided. Gapping of the physis >3 mm after reduction should raise the suspicion of entrapped periosteum that will increase the risk of premature physeal closure. Open reduction of displaced Salter-Harris type III and IV fractures is critical to maintain joint congruity and minimize the risk of physeal arrest.

The majority of pediatric finger fractures can be treated by closed means with expected excellent outcomes. However, a subset of fractures can turn “ugly,” with complications such as growth arrest, malunion, and joint dysfunction if not recognized and treated appropriately. The present paper discusses several fractures in a child’s fingers that can cause substantial problems if not recognized promptly, highlighting important themes in the evaluation and treatment of a child’s injured finger.

Children’s ankle fractures are the second most common growth plate fractures in humans and one of the top 10 reasons for pediatric orthopaedic hospital admissions. Because triplane and Tillaux fractures occur during the period of distal tibial physeal closure, they are considered transitional injuries. The distal tibial physis closes in a unique, asymmetric pattern (middle, then medial, and finally lateral), and it is the portion of the physis that is open at the time of injury that is vulnerable to fracture in this age group. Triplane and Tillaux fractures occur after supination external rotation and compression stress with unpredictable multiplanar fracture patterns. The fracture may appear different on different x-ray projections, making computed tomography mandatory to determine the number of fragments. Because most of these fractures are intra-articular, anatomic or near-anatomic reduction of the joint surface is recommended to minimize future posttraumatic ankle arthritis. Because these fractures occur at the end of growth, they rarely result in growth arrest.

Legg-Calve-Perthes disease is a complex pediatric hip disorder with many uncertainties. Various theories on its etiology have been proposed but none have been validated conclusively. Through experimental studies, however, some insight into the pathogenesis of a femoral head deformity after ischemic necrosis has been gained. These studies reveal that mechanical and biological factors contribute to the development of the femoral head deformity. Better understanding of the pathobiology of Legg-Calve-Perthes disease will lead to the development of more effective treatments, which are able to specifically target the pathogenic processes.

Growth in childhood and in puberty has a major influence on the evolution of spinal curvature. The yearly rate of increase in standing height and sitting height, bone age, and Tanner signs are essential parameters. Additionally, biometric measurements must be repeated every six months. Puberty is a turning point. The pubertal diagram is characterized by two phases: the first two years are a phase of acceleration, and the last three years is a phase of decelaration. Thoracic growth is the fourth dimension of the spine. Bone age is an essential parameter. Risser 0 covers two third of the pubertal growth. On the acceleration phase, olecranon evaluation is more precise than the hand. On the deceleration phase, the Risser sign must be completed by the hand maturation. A 30 degree curve at the very beginning of puberty has 100% risk of surgery. Any spinal, if progression is greater than 10 degree per year on the first two years of puberty the surgical risk is 100%.

A small subset of serious injuries to the pediatric elbow, deemed “TRASH” lesions, are easily missed on radiograph because of their benign appearance. These lesions however, represent a group of osteochondral injuries, which if treated insufficiently result in chronic long-term consequences. Epiphyseal separations, a displaced intra-articular medial condyles before ossification of the secondary center, capitellar shear fractures, radial head fractures with radiocapitellar subluxation and osteochondral fractures of the olecranon, radial head or distal humerus with joint incongruity comprise the group of “TRASH lesions”. These injuries are usually seen in children less than 10 years of age who sustain high-energy trauma. The challenge is a prompt diagnosis requiring a high level of suspicion and early additional imaging. Many of these injuries are displaced and unstable requiring anatomic reduction, internal fixation with or without soft tissue repair for further stability. These injuries when diagnosed late, missed completely or treated improperly without aggressive surgical care can result in long-term complications. Surgical reconstruction of the late presenting malunion is difficult.

Fractures of the distal radius account for 80 percent of pediatric forearm fractures. The rapid growth of the distal radial physis and the on-going transformation of the metaphysic explain the propensity for fractures in this location and the potential for fracture remodeling. Fractures of the distal ulna are less common and usually occur in conjunction with fractures of the distal radius. In general both injuries can be managed by closed treatment and casting. Indications for skeletal fixation and/or open reduction are discussed. Complications are infrequent but not insignificant and usually treatable with early recognition and appropriate intervention.

Acceptable alignment of forearm fractures in children is controversial. An initial attempt at closed reduction in the emergency department is appropriate for the majority of these injuries. Complex or unstable fractures and those that cannot be maintained in acceptable alignment are candidates for surgical intervention. As a general guideline, fractures with complete displacement will remodel satisfactorily. However, angulation may be more critical for preservation of forearm rotation. Up to 15 degrees angulation is recommended as maximum angulation for mid-shaft and distal-shaft fractures in children younger than 8 years old. But 10 degrees is recommended as the maximum acceptable angulation for older children and proximal shaft fractures. When malunion is greater than this, remodeling is unreliable but may occur for fractures with less than 20-30 degrees of angulation.
