RESUMEN
BACKGROUND: After arthroscopic Bankart repair (ABR) for anterior glenohumeral instability (GHI), adolescent athletes have higher rates of subsequent recurrent GHI than any other subpopulation. Elucidating which adolescents are at highest risk of postoperative recurrent GHI may optimize surgical decision-making. PURPOSE: To identify prognostic factors associated with subsequent recurrent GHI requiring revision stabilization surgery (RSS) after ABR. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: The study included patients 12 to 21 years old who had undergone ABR for anterior GHI at a pediatric tertiary care hospital by 1 of 5 sports medicine fellowship-trained surgeons between 2000 and 2020. A multivariate Cox proportional hazards model, with percentage of patients with recurrent GHI undergoing subsequent RSS, was used with a time-to-event outcome analysis. The Cox model effects were expressed as the hazard ratio (HR). All tests were 2-sided, with an alpha of .05. RESULTS: Records of 488 adolescent patients with ABR (78% male; mean age, 16.9 ± 1.98 years) were analyzed. Of these, 86 patients (17.6%) underwent subsequent RSS for recurrent GHI, yielding a cumulative risk of 8.8% at 2 years, 16.5% at 5 years, and 20% at 15 years. RSS occurred at a mean of 2.6 ± 2.1 years after ABR. Risk factors for RSS included >1 preoperative dislocation (2 dislocations: HR = 7.4, P = .0003; ≥3 dislocations: HR = 10.9, P < .0001), presence of a Hill-Sachs lesion (small: HR = 2.5, P = .0114; medium-large: HR = 4.2, P = .0004), younger age (1-year decrease: HR = 1.2, P = .0015), and participation in contact sports (HR = 1.8, P = .01). Adolescents with only 1 preoperative dislocation had a cumulative incidence of RSS (3.2%), which was significantly lower than those with 2 (24.2%) or ≥3 preoperative dislocations (33.5%). CONCLUSION: The number of dislocations before index ABR was the strongest risk factor for recurrent GHI requiring RSS in adolescents with anterior GHI, with 2 dislocations conferring >7-fold increased risk compared with a single preoperative dislocation. Other significant risk factors included the presence of a Hill-Sachs lesion, younger age, and participation in contact sports.

The aim of this study was to compare early clinical and radiographic results of single- versus double-pin fixation of unstable pediatric distal radius fractures. A total of 103 consecutive closed distal radius fractures treated with either single or double percutaneous pinning at a tertiary level I pediatric hospital were analyzed. All patients had open physes and had fractures that failed initial closed reduction and casting. Postoperative fracture displacement was assessed by measuring the difference in angulation of the radius in the anteroposterior and lateral views from intraoperative fluoroscopic images to postoperative radiographs taken on the day of pin removal. Complications were identified from the medical record review. In 103 operative distal radius fractures in 101 patients (70 males, 31 females), 52 and 51 distal radius fractures were treated with single and double pinning, respectively. The median [interquartile range (IQR)] age at the time of surgery was 12.1 (9.0-14.0) years, with the single-pinning group being younger by 1.9 years (Pâ <â 0.01). Median (IQR) postoperative angulation in the anteroposterior radiograph (coronal plane) was 2° (1-7°) with one pin versus 1° (0-2°) with two pins (Pâ <â 0.01). Median (IQR) postoperative angulation in the lateral radiograph (sagittal plane) was 3° (1-10°) with one pin versus 1° (0-2°) with two pins (Pâ <â 0.01). There were no significant differences in complications between the single- and double-pinning groups. Double-pin fixation resulted in a statistically significant, but clinically negligible, reduction in postoperative fracture displacement compared with single-pin fixation. Complication rates were similar in both groups. These findings suggest that either single- or double-pinning techniques can be effective, provided appropriate reduction and postoperative immobilization are achieved.
RESUMEN
Distal radius fractures are the most common skeletal injuries requiring intervention in children. These injuries are classified by fracture pattern, location, displacement, and angulation. While each unique fracture pattern warrants slightly modified treatment plans and follow-up, the goals of treatment remain constant. Successful outcomes depend on restoration of motion and function, and attaining acceptable sagittal and coronal alignment is a necessary first step. For displaced fractures, closed reduction is often necessary to restore alignment; well-molded cast application is important to maintain fracture alignment. Fractures with bayonet apposition, if well aligned, may not need formal reduction in some patients. Special attention should be paid to the physis-not only for physeal-involving fractures but also for all distal radius fractures-given that the proximity to the physis and amount of remaining skeletal growth help guide treatment decisions. Casting technique is essential in optimizing the best chance in maintaining fracture reduction. Surgical intervention may be indicated for a subset of fractures when acceptable alignment is not achieved or is lost at subsequent follow-up. Even among experts in the field, there is little consensus as to the optimal treatment of displaced metaphyseal fractures, illustrating the need for prospective, randomized studies to establish best practices.
RESUMEN
Background: Most healthcare providers utilize magnetic resonance imaging (MRI) to assist in diagnosing and treating osteochondritis dissecans (OCD) of the capitellum. However, consensus on imaging features that portend clinically relevant information in the care of these lesions has not been determined. Purpose: To conduct a survey on the MRI features of a capitellar OCD that are salient for clinical decision-making using a classic Delphi protocol. Study Design: A consensus statement. Methods: Invitations to participate were sent to 33 healthcare providers identified as capitellar OCD experts. A classic 3-round survey method was used to gather agreement and consensus on the level of importance for clinical decision-making on 33 MRI features. A concise list of features that guide decision-making on the stability of an OCD lesion and the ability of an OCD lesion to heal with nonoperative care was also identified. Agreement and consensus were determined a priori as ≥66%. Results: Of the 33 identified experts, 20 agreed to participate, and 17 (52%) completed all 3 rounds. Of the 33 MRI features evaluated, 17 reached agreement as important for clinical decision-making by the experts. Consensus was reached for a concise list of MRI features that were significant to decision-making (94%), suggestive of a stable lesion (100%), had the potential to heal with nonoperative treatment (94%), were suggestive of an unstable lesion (100%), and had low potential to heal with nonoperative treatment (88%). Conclusion: This 3-round Delphi process produced consensus on clinically relevant MRI features that contribute to clinical decision-making for capitellar OCD. The results of this study will be used as the basis for an interrater reliability assessment of the identified salient features, creating the foundation for developing a reliable MRI assessment tool rooted in clinical experiences. The development of a standardized assessment of capitellar OCD is intended to improve clinical practice and patient outcomes.
RESUMEN
OBJECTIVES: To compare the clinical, radiographic, and patient-reported outcomes of nonoperative and operative treatment of adolescents with comminuted "Z-type" midshaft clavicle fractures. DESIGN: Prospective observational cohort. SETTING: Eight tertiary care pediatric centers. PATIENT SELECTION CRITERIA: Patients aged 10-18 years who were treated either operatively or nonoperatively for a diaphyseal clavicle fracture between 2013 and 2017 were screened/enrolled at the time of injury. The current subcohort analysis was derived from a larger adolescent clavicle study population of 907 patients. OUTCOME MEASUREMENTS AND COMPARISONS: Complications and validated patient-reported outcome measures (PROs):(ASES, QuickDASH, Marx Shoulder Activity Score, EQ-5D, EQ-VAS, and patient satisfaction score) were compared between operative and nonoperative cohorts. RESULTS: Eighty-one patients (69 male [85.2%], 12 female; average age 15 years [11.1-18.7]; 78 with sports participation [96.2%]) were followed through bony healing and return to sports, while 59 patients (73%) completed 2-year follow-up with PROs, 26 of whom were treated nonoperatively and 33 treated operatively. All demographic and fracture characteristics were similar (P > 0.05) between the 2-year follow-up cohorts except for fracture shortening, which was greater in the operative cohort (23 vs. 29 mm, P = 0.01). After controlling for this potential confounder through both regression and propensity matched subgroup analysis, nonoperative versus operative cohorts showed no difference in rates of nonunion (0%), delayed union (0% vs. 2.3%, P = 1.0), symptomatic malunion (2.7% vs. 0%, P = 0.4), refracture (2.7% vs. 2.2%, P = 1.0), unexpected subsequent surgery (5.4% vs. 11.4%, P = 0.45), or clinically significant complications (5.4% vs. 16%, P = 0.17). There were no differences in any PROs between cohorts, both before and after controlling for the difference in fracture shortening (all P-values >0.05). CONCLUSIONS: In this prospective comparison of complications and 2-year PROs in adolescents with comminuted Z-type clavicle fractures, nonoperative and operative treatment yielded similar outcomes. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Optimal treatment of completely displaced midshaft clavicular fractures in adolescents remains controversial, with some favoring surgical management and others favoring a nonoperative approach. Few studies have comprehensively assessed longer-term nonoperative outcomes. PURPOSE: To prospectively assess patient-reported outcomes (PROs) and radiographic remodeling ≥5 years after injury in teenagers undergoing nonoperative treatment of completely displaced clavicular fractures. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Adolescent patients previously enrolled in a prospective study from a single institution with nonoperatively treated, completely displaced midshaft clavicular fractures ≥5 years from injury were eligible for the study. Patients were clinically evaluated for scapular dyskinesia and strength deficits. Bilateral clavicular imaging assessed residual shortening, displacement, and angulation. PROs included the American Shoulder and Elbow Surgeons (ASES), the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), Marx Shoulder Activity Scale, cosmesis, and return to sports data. RESULTS: A total of 24 patients were available for the follow-up, of whom 17 (71%) consented to additional imaging. The mean cohort age at the time of injury was 14.5 ± 1.1 years, with 88% being male. At a mean follow-up of 6.1 years, all fractures had healed, with no patient requiring secondary interventions. Significant remodeling was observed across all measurements, with improvements of 70% in shortening (22.8 to 6.8 mm; P < .001), 73% in superior displacement (13.4 to 3.6 mm; P < .001), and 83% in angulation (10.4° to 1.8°; P < .001). Thirteen patients (72%) had a >2-cm initial shortening, and all remodeled to <2 cm. PROs were almost universally excellent, with mean ASES, QuickDASH, and Marx activity scores of 99 ± 3, 1 ± 3, and 20 ± 1, respectively, with 79% of patients reporting perfect scores in all 3 domains. Most patients (58%) were completely satisfied with their shoulder appearance, 38% were more satisfied than not, 1 patient (4%) was neither satisfied nor dissatisfied, and no patients were dissatisfied. All patients except 1 who were interested in sports returned to sporting activities. PROs were not associated with bony remodeling (P > .05). CONCLUSION: Teenaged patients with completely displaced clavicular fractures treated nonoperatively can expect excellent radiographic and clinical outcomes 5 years after injury.

BACKGROUND: Understanding the challenges and potential of telehealth visits (THVs) in a large population can inform future practice and policy discussion for pediatric orthopaedic and sports medicine (OSM) care. We comprehensively assess telehealth challenges and potential in a large pediatric OSM population based on access, visit completion, patient satisfaction, and technological challenges. METHODS: Demographics, address, insurance, visit information, patient feedback, experience with video visits, and technical challenges of all 2019 to 2020 visits at our hospital were assessed (3,278,006 visits). We evaluated the differences in rate of telehealth utilization, rate of patient adherence, disparities in care access and patient satisfaction, and technological issues. RESULTS: Compared with in-person prepandemic visits, THVs had lower ratios of non-White patients (by 5.8%; P <0.001), Hispanic patients (by 2.8%; P <0.001) and patients with public insurance (by 1.8%; P <0.001), and a higher mean distance between the patient's residence and clinic (by 18.8 miles; P <0.001). There were minimal differences in median household income (average $2297 less in THV; P <0.001) and social vulnerability index (average 0.01 points lower in THV; P <0.001) between groups. THVs had comparable patient satisfaction to in-person visits. Non-White patients, Hispanics, and those with public insurance had lower ratings for both in-person visits and THVs and had more technical difficulties during their THV. CONCLUSIONS: Telehealth is a viable method of care for a range of pediatric OSM conditions, providing a similar quality of care as in-person visits with a greater geographic reach. However, in its current format, reduced disparities were not observed in pediatric OSM THVs. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Recent evidence suggests that for completely displaced midshaft clavicular fractures, surgery offers no clear benefit over nonoperative treatment in a general adolescent population from 10 to 18 years of age. However, the comparative outcomes of comminuted and/or severely shortened clavicular fractures specifically in older adolescent athletes have not been explored in a focused, methodologically rigorous fashion. HYPOTHESIS: The study hypothesis was that outcomes would be superior in older adolescent athletes who underwent operative treatment compared with nonoperative treatment for comminuted and/or severely shortened clavicular fractures. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A level 2, multicenter, prospective cohort study investigating the outcomes of midshaft fractures in adolescents between 2013 and 2017 was filtered to analyze the subcohorts of athletes 14 to 18 years of age with either fracture comminution or fracture shortening of ≥25 mm or both. Patient characteristics, injury mechanisms, fracture characteristics, and treatments were compared. Complications, rates, timing of return to sports (RTS), and patient-reported outcomes (PROs) were analyzed. RESULTS: The 2 treatment groups, which included 136 older adolescent athletes (69 nonoperative, 67 operative), showed similar distributions of primary sport type, competition level, comminution, shortening, and 2-year PRO response rate (n = 99; 73%). The operative group demonstrated 3 mm-greater mean superior displacement, which was therefore statistically controlled for as a confounder in the comparative PRO analysis. No 2-year differences in nonunion, delayed union, symptomatic malunion, refracture, clinically significant complications, or rates of RTS were detected between treatment groups. The difference in timing of RTS (operative, 10.3 weeks; nonoperative, 13.5 weeks) was statistically significant. After controlling for the minor difference in superior displacement, regression analysis and matched comparison cohorts demonstrated no differences between the nonoperative and operative groups in mean or dichotomized PRO scores. CONCLUSION: In this prospective, multicenter cohort study investigating older adolescent athletes with comminuted and/or severely shortened clavicular fractures, contrary to the study hypothesis, there were no differences in complications, RTS, or PROs between nonoperatively and operatively treated patients at 2 years. Comparably excellent outcomes of severe clavicular fractures in adolescent athletes can be achieved with nonoperative treatment.

PURPOSE: This study investigated the patterns of syndromic involvement for patients with congenital upper limb anomalies (CULAs). We hypothesize that patients with CULAs will present with predictable syndromic patterns. METHODS: This retrospective study queried the multicenter Congenital Upper Limb Differences (CoULD) Registry. Of the 4,317 patients enrolled, 578 (13%) reported one or more syndromes. Syndromes were confirmed to be recognized by the Online Mendelian Inheritance in Man. Demographics were reviewed and compared with the full CoULD registry group. Syndromes reported by five or more patients were examined to determine the type of CULA according to Oberg/Manske/Tonkin classifications. RESULTS: Of the 578 children with one or more reported syndromes, 517 had Online Mendelian Inheritance in Man recognized syndromes (cohort A), In cohort A, 58 syndromes were each represented by a single patient within the registry. Forty-eight syndromes in cohort A were reported by two or more patients, which accounted for 461 of the total patients with reported syndromes. However, VACTERL and Poland syndromes were the most commonly reported syndromes. Patients with CULAs and syndromes frequently exhibited bilateral involvement (61%), compared with the entire CoULD group (47%) and other orthopedic (50%) and medical conditions (61%) compared with the entire CoULD group (24% and 27%, respectively). Additionally, they exhibited a lower frequency of family history of a congenital orthopedic condition (21%) or a family member with the same CULA (9%) compared with the entire CoULD group (26% and 14%, respectively). CONCLUSIONS: Associated syndromes were recorded in 578 patients (13%) in the CoULD registry as follows: 58 syndromes represented by a single patient, 48 by 2 or more patients, and 23 syndromes by 5 or more patients. Rare syndromes that are only represented by a single patient are more likely to be unknown by a pediatric hand surgeon, and consultation with a geneticist is advised.

BACKGROUND: The prevalence of wrist pain among gymnasts ranges from 46% to 79%. To alleviate wrist pain, gymnasts wear wrist guards/supports (WG/S). PURPOSE: To investigate the effect of WG/S on the wrist joint through joint moment, angles, total joint range of motion (ROM) arc, and ground-reaction force (GRF). STUDY DESIGN: Controlled laboratory study. METHODS: A cross-sectional study design was used to investigate 23 female gymnasts (mean ± SD: age, 12.3 ± 1.5 years; height, 143.4 ± 7.6 cm; mass, 37.7 ± 6.6 kg; body mass index, 18.6 ± 2.9) who performed back handsprings (analyzed by first half [phase 1] and second half [phase 2]) with the following 3 conditions: no WG/S, Skids/Ultimate Wrist Supports (S/UWS), and Tiger Paws (TP). Wrist joint moments, angles, total ROM arc, and GRF were examined by the 3 conditions using analysis of variance with Bonferroni correction and effect size (Cohen d). RESULTS: For mean wrist flexion moment, both S/UWS and TP showed significantly higher values than the no-WG/S condition in landing phase 1 (S/UWS: P = .001, d = 1.30; TP: P = .019, d = 0.87). In angle comparisons in landing phase 1, no WG/S showed greater mean wrist extension angles compared with S/UWS (P = .046; d = 0.80), but no significant differences with TP (P = .096; d = 0.65). Also, in landing phase 1, total ROM arc of the right wrist was greater in the no-WG/S condition compared with S/UWS (P = .018; d = 0.88), but there were no differences with TP (P = .400; d = 0.52). CONCLUSION: These data show an increased wrist flexion moment using S/UWS and TP compared with the no-WG/S condition in landing phase 1 of back handsprings. Also, increased wrist extension angles and total arc ROM of the right wrist were found in the no-WG/S condition compared with S/UWS, but not with TP in landing phase 1. S/UWS may be helpful to reduce wrist joint angles, specifically wrist extension in landing phase 1, but both S/UWS and TP caused higher wrist flexion joint moment in landing phase 1. There were no differences found in GFG among the three variables. CLINICAL RELEVANCE: In the first half of the back handspring, wrist guards can limit wrist extension joint angles and total arc ROM; however, an increased wrist flexion moment was found when wrist guards were worn, which may potentially lead to an increased risk of injury. Injury history, especially overuse signs/symptoms, and previous surgery on the wrist joint need to be well considered before the application or use of wrist guards. Also, the amount of time/exposure wearing wrist guards should be carefully controlled in young female gymnasts.

PURPOSE: Transverse deficiency (TD) and symbrachydactyly may be difficult to distinguish due to shared phenotypes and a lack of pathognomonic features. The 2020 Oberg-Manske-Tonkin classification update modified these anomalies to include "with ectodermal elements" for symbrachydactyly and "without ectodermal elements" for TD as a defining differentiating characteristic. The purpose of this investigation was to characterize ectodermal elements and the level of deficiency and to examine whether ectodermal elements versus the level of deficiency was a greater determining factor for Congenital Upper Limb Differences (CoULD) surgeons making the diagnosis. METHODS: This was a retrospective review of 254 extremities from the CoULD registry with a diagnosis of symbrachydactyly or TD by pediatric hand surgeons. Ectodermal elements and the level of deficiency were characterized. A review of the registry radiographs and photographs was used to classify the diagnosis and compare it with the diagnosis given by the pediatric hand surgeons. The presence/absence of nubbins versus the level of deficiency as the determining factor to differentiate the pediatric hand surgeons' diagnosis of symbrachydactyly (with nubbins) versus TD (without nubbins) was analyzed. RESULTS: Based on radiographs and photographs of the 254 extremities, 66% had nubbins on the distal end of the limb; of the limbs with nubbins, nails were present on 51%. The level of deficiency was amelia/humeral (n = 9), <1/3 transverse forearm (n = 23), 1/3 to 2/3 transverse forearm (n = 27), 2/3 to full forearm TD (n = 38), and metacarpal/phalangeal (n = 103). The presence of nubbins was associated with a four times higher likelihood of a pediatric hand surgeon's diagnosis of symbrachydactyly. However, a distal deficiency is associated with a 20-times higher likelihood of a diagnosis of symbrachydactyly than a proximal deficiency. CONCLUSIONS: Although both the level of deficiency and ectodermal elements are important, the level of deficiency was a greater determining factor for a diagnosis of symbrachydactyly versus TD. Our results suggest that the level of deficiency and nubbins should both be described to help provide greater clarity in the diagnosis of symbrachydactyly versus TD.

RESUMEN
BACKGROUND: Bony remodeling of displaced clavicle fractures in adolescents remains poorly understood. PURPOSE: To evaluate and quantify clavicle remodeling in a large population of adolescents with completely displaced fractures, which were treated nonoperatively, to better understand the factors that may influence this process. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients were identified from the databases of a multicenter study group investigating the functional outcomes of adolescent clavicle fractures. Patients between the ages of 10 and 19 years with completely displaced middiaphyseal clavicle fractures that were treated nonoperatively and who had further radiographic imaging of the affected clavicle at a minimum of 9 months from initial injury were included. Fracture shortening, superior displacement, and angulation were measured on the injury and final follow-up radiographs using previously validated techniques. Furthermore, fracture remodeling was classified as complete/near complete, moderate, or minimal, using an original classification system found to have good to excellent reliability (interobserver reliability = 0.78, intraobserver reliability = 0.90). Classifications were subsequently analyzed quantitatively and qualitatively to determine the factors associated with deformity correction. RESULTS: Ninety-eight patients (mean age, 14.4 ± 2.0 years) were analyzed at a mean radiographic follow-up of 3.4 ± 2.3 years. Fracture shortening, superior displacement, and angulation significantly improved during the follow-up period by 61%, 61%, and 31%, respectively (P < .001). Furthermore, while 41% of the population had initial fracture shortening >20 mm at final follow-up, only 3% of the cohort had residual shortening >20 mm. Fracture remodeling was found to be associated with follow-up time; those with longer follow-up time demonstrated more remodeling (P = .001). Eighty-five percent of patients aged <14 years and 54% of patients aged ≥14 years at time of injury with a minimum follow-up of 4 years underwent complete/near-complete remodeling. CONCLUSION: Significant bony remodeling occurs in adolescent patients with completely displaced clavicle fractures, including older adolescents, and appears to continue over longer time intervals, even beyond the adolescent years. This finding may help explain the low rate of symptomatic malunions in adolescents, even in severely displaced fractures, and particularly when compared with rates reported in adult studies.

PURPOSE: Conventional teaching dictates that timely diagnosis and expeditious treatment of unicondylar phalangeal fractures are essential to restore articular congruity, which allows for optimal range of motion and function. The objective of this study was to compare the radiographic and clinical results of surgical treatment of acute and chronic unicondylar phalanx fractures in pediatric patients. METHODS: Thirty-four patients with unicondylar phalangeal fractures underwent surgical intervention at a pediatric tertiary care center from 2004 to 2016. A fracture was defined as acute if an interval of 4 weeks or less had elapsed between the date of injury and date of surgery and chronic if an interval of more than 4 weeks had elapsed between the date of injury and date of surgery. Preoperative and postoperative radiographs were assessed. The joint alignment was determined by measuring the angle between the longitudinal axis of the phalanx and a line tangential to the articular condyles on anteroposterior radiographs. RESULTS: There were 24 patients (71%) with acute and 10 (29%) with chronic fractures. An oblique volar fracture pattern was most common in both the groups. The average joint alignment obtained from the anteroposterior radiographs at presentation was 6° in the acute group and 12° in the chronic group. The surgical procedures performed included closed reduction and percutaneous pinning, open reduction and internal fixation, osteoclasis or osteotomy and fixation, and corrective advancement osteotomy. The posttreatment alignment was within 3° of neutral in 21 patients (88%) with acute injury and 8 (80%) with chronic injury. The average interphalangeal joint range of motion at the final clinic visit was 1°-92° in the acute group and 4°-85° in the chronic group. One patient with chronic injury developed avascular necrosis after treatment with corrective osteotomy. CONCLUSIONS: The patterns and characteristics of unicondylar phalanx fractures are similar between pediatric patients and adults. The radiographic alignment and digital motion are improved with surgical reduction and fixation, regardless of chronicity. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
RESUMEN
BACKGROUND: Radial head and neck fracture malunion can lead to pain, stiffness, deformity, and functional limitations. This study analyzed the early radiographic and functional outcomes of corrective osteotomy for symptomatic radial head and/or neck malunion in skeletally immature patients. METHODS: Thirteen pediatric patients treated with corrective osteotomy for symptomatic radial head and/or neck malunion from 2004 to 2018 were identified. Radiographic union, range of motion, pain, and complications were recorded. Functional outcomes were assessed using the Broberg and Morrey Elbow Scale. RESULTS: The average age at the time of surgery was 12.3 years (range: 8.6 to 16.3). The mean time from injury to osteotomy was 7.5 months (range: 2 to 24.1 mo). Before osteotomy, mean radial head-shaft angulation was 23 degrees (range: 5 to 57 degrees), mean displacement was 76% (range: 0 to 55), average elbow flexion contracture was 18 degrees (range: 0 to 60 degrees), and average elbow flexion was 112 degrees (range: 95 to 135 degrees). After a mean follow-up of 14.3 months, 12 of 13 osteotomies (92%) healed; 1 patient had a painless nonunion. The number of patients reporting pain decreased from 9 to 2 ( P =0.012). Radiographic alignment and range of motion improved in all patients. Mean angulation and displacement improved to 8 degrees (range: 2 to 15 degrees, P =0.001) and 3% (range: 0 to 18 degrees, P =0.001), respectively. Mean elbow flexion contracture was reduced to 5 degrees (range: 0 to 30 degrees, P =0.008), and the average elbow flexion increased to 128 degrees (range: 100 to 135 degrees, P <0.001). Three patients underwent implant removal for complications, including heterotopic ossification and avascular necrosis. Physeal arrest did not lead to any adverse sequelae. The sole case of avascular necrosis had a reduced range of motion but no pain. The mean postoperative Broberg and Morrey score was 91.1; 7 patients had excellent postoperative scores, 4 good, and 2 fair. CONCLUSIONS: Corrective osteotomy for symptomatic malunion of the radial head and/or neck in skeletally immature patients can improve elbow alignment, motion, pain, and function. Preservation of the soft-tissue attachments to the proximal epiphysis and rigid internal fixation are critical components of this surgical technique. LEVEL OF EVIDENCE: Therapeutic Level IV.

INTRODUCTION: More than 1 in 4 pediatric fractures involves the distal radius. Most prior epidemiologic studies are limited to retrospective, single center investigations, and often include adults. This study aims to describe the contemporary epidemiology of pediatric distal radius fractures using prospectively collected data from a multicenter Pediatric Distal Radius Fracture Registry. METHODS: Patients aged 4 to 18 years diagnosed with a distal radius fracture from June 2018 through December 2019 at 4 tertiary care pediatric centers were screened and enrolled in this prospective longitudinal cohort study. Patients were excluded if they presented with bilateral distal radius fractures, polytrauma, or re-fracture. Demographic information, mechanism of injury, fracture characteristics, associated injuries, and procedural information were recorded. All radiographs were reviewed and measured. Descriptive statistics and bivariate analyses were performed. RESULTS: A total of 1951 patients were included. The mean age was 9.9±3.3 years, and 61.3% of patients were male ( P <0.001). Most injuries occurred during a high-energy fall (33.5%) or sports participation (28.4%). The greatest proportion of fractures occurred during the spring months (38.5%). Torus fractures (44.0%) were more common than bicortical (31.3%) or physeal (21.0%) fractures. Of the physeal fractures, 84.3% were Salter-Harris type II. Associated ulnar fractures were observed in 51.2% of patients. The mean age at injury was higher for patients with physeal fractures (11.6±2.9 y) than patients with torus or bicortical fractures (9.4±3.1 and 9.6±3.1 y, respectively; P <0.001). Thirty-six percent of distal radius fractures underwent closed reduction and 3.3% underwent surgical fixation. Patients treated with closed reduction were more likely to be male (68.7% vs. 57.2%; P <0.001), obese (25.3% vs. 17.2%; P <0.001), and have bicortical fractures (62.2% vs. 14.5%; P <0.001). CONCLUSIONS: Distal radius fractures in children have a male preponderance and are most likely to occur in the spring months and during high-energy falls and sports. Physeal fractures tend to occur in older children while torus and bicortical fractures tend to occur in younger children. LEVEL OF EVIDENCE: Level I-prognostic.

PURPOSE: Screw fixation with iliac crest bone grafting (ICBG) is a well-studied treatment for pediatric scaphoid nonunions. Studies in adults, as well as in pediatric spine fusions, have demonstrated high rates of complications with ICBG, including longer-term donor site pain. We hypothesized that in pediatric patients undergoing ICBG for scaphoid nonunion, the donor site complication rate would be lower than that reported in other populations. METHODS: Records of patients ages 0-18 years at a single institution undergoing surgical reconstruction for scaphoid nonunion from 1995 to 2016 were reviewed. Patient and surgical variables were recorded, including how ICBG was harvested. Donor site complications were recorded, including donor site pain beyond 30 days after surgery, infection, peri-incisional or lower extremity numbness at any point after surgery and reoperation at the donor site at any time point after surgery. RESULTS: During the study period, 119 wrists in 117 patients underwent internal fixation and ICBG for scaphoid nonunion. The average age was 16 years; mean follow-up was 1 year. The majority of wrists (73, 62.9%) underwent harvest of both outer and inner tables of the iliac crest; 38 (31.9%) had only outer table harvested; 5 (4.3%) had only cancellous graft harvested. Ten wrists (8.4%) had a donor site complication. The most common donor site complication was donor site pain beyond 30 days after surgery (5, 4.2%), followed by numbness (4, 3.4%). No infections, seromas, or reoperations at the donor site occurred. In comparison to those subjects who did not experience complications, we found no difference based on the age at surgery or the type of graft used. Female patients were more likely to have a recorded complication than males. CONCLUSIONS: Donor site morbidity for iliac crest grafting in pediatric patients undergoing scaphoid nonunion surgery appears to be lower than that previously reported in adult patients. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

BACKGROUND: A primary challenge in the treatment of capitellar osteochondritis dissecans (OCD) is accurate imaging assessment. Radiographic classification consensus is not available in the current literature, and correlation of radiographs with lesion stability and resultant best treatment is lacking. PURPOSE: To determine the inter- and intrarater reliability of the presence or absence and common radiographic characteristics of capitellar OCD lesions. STUDY DESIGN: Cohort study (Diagnosis); Level of evidence, 3. METHODS: Anteroposterior, lateral, and oblique radiographs for 29 cases were reviewed by 7 orthopaedic surgeons. Images were assessed for elbow anthropometry and morphology, OCD presence, lesion characteristics, the presence of progeny bone and progeny features, and radial head abnormalities. Intra- and interrater reliability was assessed using Fleiss and Cohen kappa for nominal variables and intraclass correlation coefficients (ICCs) for continuous variables. RESULTS: Surgeons demonstrated substantial to excellent inter- and intrarater reliability when assessing elbow characteristics: anthropometric (interrater ICC, 0.94-0.99; intrarater ICC, 0.82-0.96) and morphologic (Fleiss, 0.61-0.76; Cohen, 0.68). When the OCD lesion was assessed, fair to moderate interrater agreement was found for classifying the absence or presence of a lesion (Fleiss, 0.28-0.46) and the location of the OCD (Fleiss, 0.24-0.52), poor agreement for assessing the contour of the lesion (Fleiss, 0.00-0.09), and excellent agreement for measuring the size of the lesion (ICC, 0.82-0.94). Poor to fair interrater agreement was found for radial head abnormalities (Fleiss, 0.00-0.27). Progeny bone visualization and fragmentation demonstrated moderate interrater agreement (Fleiss, 0.43-0.47) where displacement of the bone demonstrated poor interrater agreement (Fleiss, 0.11-0.16). Intrarater agreement for OCD lesion characteristics, progeny bone visualization, and progeny bone features was moderate to excellent. CONCLUSION: Given only the fair to moderate agreement among raters for identifying OCD on radiographs, this imaging modality may not serve as a dependable screening tool in isolation. Additional imaging should be obtained if the clinical presentation suggests capitellar OCD and a definitive diagnosis is not possible with radiographs. However, clinicians can reliability measure the size of radiographically apparent OCD, suggesting that radiographs may serve as an appropriate imaging modality for follow-up care.

BACKGROUND: The optimal treatment of midshaft clavicle fractures is controversial. Few previous comparative functional outcome studies have investigated these fractures in adolescents, the most commonly affected epidemiologic subpopulation. PURPOSE/HYPOTHESIS: The purpose was to prospectively compare the outcomes of operative versus nonoperative treatment in adolescents with completely displaced midshaft clavicle fractures. The study hypothesis was that surgery would yield superior outcomes. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: Patients aged 10 to 18 years treated for a midshaft clavicle fracture over a 5-year period at 1 of 8 pediatric centers were prospectively screened, with independent treatment decisions determined by individual musculoskeletal professionals. Demographics, radiographic clinical features, complications, and patient-reported outcomes (PROs) were prospectively recorded for 2 years. Regression and matching techniques were utilized to adjust for potential age- and fracture severity-based confounders for creation of comparable subgroups for analysis. RESULTS: Of 416 adolescents with completely displaced midshaft clavicle fractures, 282 (68) provided 2-year PRO data. Operative patients (n = 88; 31%) demonstrated no difference in sex (78% male) or athletic participation but were older (mean age, 15.2 vs 13.5 years; P < .001), had more comminuted fractures (49.4% vs 26.3%; P < .001), and had greater fracture shortening (25.5 vs 20.7 mm; P < .001) than nonoperative patients (n = 194; 69%). There was no difference in mean PRO scores or rates of "suboptimal" scores (based on threshold values established a priori) between the operative and nonoperative treatment groups (American Shoulder and Elbow Surgeons, 96.8 vs 98.4; shortened version of the Disabilities of the Arm, Shoulder and Hand, 3.0 vs 1.6; EuroQol [EQ] visual analog scale, 93.0 vs 93.9; EQ-5 Dimensions index, 0.96 vs 0.98), even after regression and matching techniques adjusted for confounders. Operative patients had more unexpected subsequent surgery (10.4% vs 1.4%; P = .004) and clinically significant complications (20.8% vs 5.2%; P = .001). Overall, nonunion (0.4%), delayed union (1.9%), symptomatic malunion (0.4%), and refracture (2.6%) were exceedingly rare, with no difference between treatment groups. CONCLUSION: Surgery demonstrated no benefit in patient-reported quality of life, satisfaction, shoulder-specific function, or prevention of complications after completely displaced clavicle shaft fractures in adolescents at 2 years after injury.

INTRODUCTION: This study investigates how previous simulation training and clinical experience affects trainee performance when manipulating a foot, applying a Ponseti clubfoot cast, and performing an Achilles tenotomy on a clubfoot simulator. METHODS: Sixty-four Accreditation Council for Graduate Medical Education orthopaedic trainees participated in the 2017 to 2018 Top Gun (TG) skills competition at the International Pediatric Orthopaedic Symposium. Trainees were judged by expert pediatric orthopaedic surgeons on how they manipulated a clubfoot model, applied a cast, and performed a simulated tendoachilles tenotomy (TAT). An analysis was done to correlate the test variables with a contestant's TG Ponseti score. RESULTS: Twenty-one contestants with previous residency training using synthetic clubfoot models scored higher (P = 0.007) than those trainees without training. Trainees who had applied >10 clubfoot casts and who participated in >10 TATs in training also scored higher (P = 0.038 and P = 0.01, respectively). Thirteen contestants who had previously attended an International Pediatric Orthopaedic Symposium meeting and seven contestants who attended a American Academy of Orthopaedic Surgery clubfoot workshop scored higher (P = 0.012 and P = 0.017 respectively). DISCUSSION: Clinical and previous simulation experience related to the Ponseti method correlated with improved performance on our Ponseti simulation. Trainees who had previous experience with >10 clubfoot casts and >10 TATs scored higher during TG than less experienced trainees.

BACKGROUND: This study characterizes the outcomes and complications of surgical reconstruction of distal radioulnar joint (DRUJ) instability using the extensor retinaculum (Herbert sling). Our hypothesis was that extensor retinaculum reconstruction is a reliable method of DRUJ stabilization in adolescents. METHODS: This was a retrospective study of pediatric patients treated surgically using the Herbert sling for DRUJ instability at a single institution. We identified 22 subjects who underwent surgery at an average of 16.2 years of age (range, 12-18 years). Medical records and available imaging were reviewed for all subjects, and patients were contacted to participate in the prospective completion of the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire. RESULTS: Preoperative symptoms were more commonly pain (95%) than feelings of DRUJ instability (45%), although 100% had instability on physical examination. Eight (36%) patients demonstrated limited supination preoperatively. Twenty-one subjects (95%) noted prior injury to that wrist, 15 of which were distal radius fractures. Surgery consisted of stabilization of the DRUJ using extensor retinaculum, in concert with other procedures to address all potential causes of wrist pain. Postoperatively, DRUJ stability was maintained in 21 of 22 subjects. Of the 12 patients who provided functional outcome scores, median QuickDASH score was 7.6 (range, 0-45). CONCLUSIONS: Distal radioulnar joint instability in adolescents is often preceded by fracture of the distal radius. Surgeons must maintain a high level of suspicion to appropriately diagnose DRUJ instability, which is often not an isolated pathoanatomical problem. The Herbert sling technique using extensor retinaculum can successfully confer DRUJ stability in this population.
