RESUMO
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: The long-term prognosis of baseball and softball players diagnosed with Little League elbow (LLE) and Little League shoulder (LLS) is unknown. Many of these athletes are potentially at risk of developing future shoulder and elbow injuries that may require surgical intervention. This study's purpose is to retrospectively assess 5-year patient-reported outcomes and career progression of a series of youth baseball and softball players diagnosed with LLE and LLS. METHODS: This institutional review board-approved, single-center, retrospective study evaluated 5-year outcomes of a cohort of youth baseball and softball players diagnosed with LLE and LLS between 2013 and 2017. Demographic and clinical data was recorded including age, gender, primary position, and months played per year. A standardized phone survey was obtained approximately 5 years post-treatment to assess upper extremity function, career progression, and pain recurrence. RESULTS: Sixty-one patients (44 LLE, 17 LLS) met the inclusion criteria and participated in a standardized phone survey. The mean age at the time of diagnosis was 13.2 years and all but one of the athletes were male. On average, about 80% (34/44 LLE, 15/17 LLS) played baseball 9 months or more per year. After diagnosis and nonoperative management, more than 80% (37/44 LLE, 14/17 LLS) were able to return to competition, but up to 40% of players changed positions (9/44 LLE, 7/17 LLS). Five years later, less than half (21/44 LLE, 8/17 LLS) were playing baseball actively. The recurrence rate was >20% (9/42 LLE, 6/17 LLS) with a mean time of recurrence of 8.8 months. Patients who experienced symptom recurrence were less likely to play baseball 5 years later and had lower patient-reported outcomes. CONCLUSIONS: A diagnosis of LLE and LLS in early adolescence can be a setback for a young athlete. Fortunately, most athletes will be able to return to competition with â¼50% still competing at 5 years. Very few will progress to future arm surgery, but recurrence rates are relatively high, and these athletes are less likely to participate in their sport 5 years later. LEVEL OF EVIDENCE: Level IV-Retrospective cohort study.

Background: Destabilizing shoulder injuries are common in high school American football players; however, the rate of recurrent glenohumeral instability and return to play after arthroscopic labral stabilization surgery remains unknown. Purpose/Hypothesis: The purpose of this study was to determine the rate of recurrent instability on return to competitive high school football after arthroscopic shoulder labral stabilization and capsulorrhaphy procedures. It was hypothesized that the instability rate would be greater in players with more years of eligibility remaining (YER) to play at the high school level. Study Design: Case series; Level of evidence, 4. Methods: Consecutive male high school football players with at least 1 YER who sustained at least 1 anterior traumatic inseason shoulder instability episode and underwent arthroscopic stabilization between 2012 and 2017 were identified. Patients and/or families were contacted by phone to discuss (1) recurrent instability episodes and (2) return to competitive sport and/or recreational athletic activity. Statistical analysis was conducted using chi-square tests to compare recurrent shoulder instability with return to play and YER. Results: A total of 45 football players aged 14 to 17 years were included, with a mean follow-up of 4.1 years. Most patients (60%) chose not to return to competitive football, due mainly to fear of recurrent injury. Overall, the recurrent instability rate was 15.6% (7/45). The instability rate in players who returned to football was 16.7%, with 66.7% requiring revision surgery. The instability rate in patients who did not return to football was 14.8%, with no revision procedures required. In players who returned to football, the instability rate in YER group 4 was significantly higher than that in YER groups 1 to 3 (42% vs 10.5%, respectively, P = .03), with each year of play conferring an additional 10% risk of reinjury. There was a significant difference in the type of recurrent instability in players who returned to any sport versus those who did not (P = .029). Conclusion: High school football players who returned to competitive play after arthroscopic shoulder stabilization surgery experienced a higher rate of recurrent instability that was dependent on their YER. Over half of the players chose not to return to football, with fear of reinjury being the most common reason.
RESUMO
Background: Increased posterior tibial slope angle (PTSA) has been shown to be an important risk factor for anterior cruciate ligament (ACL) injury. PTSA modulation is not utilized routinely to reduce risk of primary rupture or graft failure. Displaced tibial tubercle (TT) fractures in the skeletally immature are associated with potential growth arrest and may be used as a model to study PTSA changes in this setting. Purpose/Hypothesis: To quantify the change in PTSA (ΔPTSA) after operative treatment of displaced TT fractures in skeletally immature patients. It was hypothesized that there would be a progressive decrease in PTSA after TT injury and that rate of ΔPTSA would be highest during peak growth velocity. Study Design: Case series; Level of evidence, 4. Methods: Included were 22 patients (n = 23 knees; mean chronological and bone age at injury, 14 years; 86% male) who underwent surgery for displaced TT fracture. PTSA was measured on lateral radiographs at time of surgery and subsequent follow-up, and bone age at the time of injury was determined using radiographic standards. The rate of ΔPTSA for individual patient, total cohort, and sex-based subgroup trends were determined via linear regression (degrees per month; positive value indicates relatively anterior). Individual patient regression coefficients were averaged into bone age cohorts. Results: Average follow-up was 17 months (range, 6-52 months). The mean PTSA was -12°± 2.4° at the time of injury, and the mean ΔPTSA for the cohort was 0.30°± 0.31° per month (range, -0.27° to 0.97° per month). Linear regression demonstrated a significant relationship between months postfixation and PTSA, demonstrating a ΔPTSA of 0.31° per month (95% confidence interval [CI], 0.24° to 0.38°; P < .001). The highest ΔPTSA was seen at bone age 14 years (mean, 0.58°± 0.44° per month). The mean absolute change in PTSA from injury to final follow-up was 4.1° (range, -3.4° to 21°). Conclusion: Our data suggested that PTSA becomes more anterior after operatively treated pediatric TT fractures and that ΔPTSA may be influenced by bone age. This concept may be useful in considering surgical modulation of excessive PTSA in the pediatric ACL-deficient knee.
RESUMO
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.

Background: Glenolabral articular disruption (GLAD) lesions may occur in adolescents with anterior shoulder instability, resulting in articular cartilage loss and reduced functional glenoid surface area. Purpose/Hypothesis: To compare failure rates and patient-reported outcomes (PROs) between adolescents with versus without GLAD lesions who were treated for anterior shoulder instability with arthroscopic stabilization. It was hypothesized that the comparison would yield no significant differences. Study Design: Cohort study; Level of evidence, 3. Methods: Patients aged ≤18 years who were treated for anterior shoulder instability with arthroscopic stabilization between 2010 and 2021 were retrospectively identified. Those patients with a GLAD lesion identified at the time of surgery were compared with patients with >2 years of retrospective follow-up who were matched to the no-GLAD cohort according to pathology and management. Demographic and patient characteristics including recurrent instability, complications, and reoperations were recorded. All patients in the GLAD cohort were contacted to obtain PRO data, including the Single Assessment Numeric Evaluation; the shortened version of the Disabilities of the Arm, Shoulder, and Hand questionnaire; and the Pediatric Adolescent Shoulder Survey. Patients were also asked about recurrent instability and additional shoulder problems. Results: Of 35 included patients (mean age, 15.4 ± 1.6 years; 80% male), 15 patients (43%) with GLAD lesions and 26 patients without GLAD lesions were identified. Both cohorts had similar patient characteristics, number of anchors, and anchor constructs; the mean follow-up period was significantly different (GLAD vs no-GLAD, 6.9 ± 3.3 vs 3.4 ± 1.2 years, respectively; P < .001). Seven of 15 GLAD patients (46.7%) underwent loose body removal; 4 of 15 GLAD patients (26.6%) and 9 of 26 no-GLAD patients (34.6%) had recurrent subjective instability (P = .7). No significant group differences were found in PRO scores, reoperation rates (15% no-GLAD vs 20% GLAD), or percentage of patients with recurrent instability between cohorts (P > .05). Conclusion: Adolescent patients with and without GLAD lesions treated arthroscopically for anterior shoulder instability had similar PROs and failure rates at intermediate duration of follow-up. GLAD lesions may be managed in a similar surgical manner as isolated Bankart tears in teenagers, with expectations of similar outcomes.
RESUMO
Background: The pediatric/adolescent shoulder survey (PASS) score is a subjective measure of shoulder symptomology in younger patients. Purpose: To establish the minimal clinically important difference (MCID) and minimal detectable change (MDC) for the PASS score in adolescents after surgical treatment for shoulder instability. Study Design: Case series; Level of evidence, 4. Methods: Included were patients aged 12.5 to 23 years who underwent surgical treatment for shoulder instability and who had completed PASS forms preoperatively and at 3 months postoperatively. The MCID was established using an anchor-based approach, with the Single Assessment Numeric Evaluation (SANE) and shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) as anchors. Change in PASS score between anchor groups was determined using receiver operating characteristic curve analysis. MDC with 90% confidence (MDC90) was also calculated. Range of motion and strength data at 3-month follow-up were evaluated to identify the optimal postoperative PASS score. Factors associated with improvement in PASS score beyond the MDC90 and MCID were determined in a subset of patients with ≥6-month follow-up data. Results: A total of 95 patients were included. The mean PASS score improved significantly from preoperatively to postoperatively (57 ± 15 to 75 ± 16; P < .001). The anchor-based MCID ranged from 12.5 to 13.2 points, with an area under the receiver operating characteristic (AUC) curve of 0.87 for the SANE and 0.99 for the QuickDASH. The MDC90 was 16.5 points. The optimal PASS score at 3 months after surgery was ≥85 (AUC, 0.66). Shorter duration of symptoms, lower preoperative forward elevation, and higher preoperative external rotation were associated with improvement in PASS score above the MDC90 and/or MCID for the subset of patients (n = 25) with ≥6-month follow-up data. Increased number of suture anchors, less preoperative external rotation deficit, and number of previous dislocations had a moderate effect on improvement in outcomes. Conclusion: A postoperative increase in PASS score of ≥16.5 points had a 90% chance of being a true-positive change, while a score change of approximately 13 points was likely clinically relevant. The optimal PASS score after surgery was ≥85. Shorter duration of symptoms, preoperative range of motion, number of surgical anchors, and number of previous dislocations were associated with achieving a clinically relevant improvement in PASS score at minimum 6 months postoperatively.
RESUMO
BACKGROUND: The aim of this study was to assess the patient demographics, epidemiology, mechanism of injury, and natural history of sublime tubercle avulsion injuries. METHODS: A multicenter retrospective study was performed in which sublime tubercle avulsion injuries were identified by surgeon records and database query of radiology reports. Demographic data and imaging were reviewed for each case, and injuries were classified as type 1 (isolated injuries with a simple bony avulsion or periosteal stripping) or type 2 (complex injuries with an associated elbow fracture or dislocation). Treatment modality and evidence of radiographic healing at a minimum of 3 months were collected. RESULTS: Forty patients (78% male) with a median age of 15 years (range, 8 to 19 years) were identified with sublime tubercle avulsion injuries. Sixty-eight percent of cases (n=27) were determined to be type 1 injuries, and 32% (n=13) were classified as type 2 injuries. The majority of type 1 injuries (59%) occurred via a noncontact mechanism in overhead-throwing athletes, whereas 100% of the type 2 injuries were sustained via a contact mechanism. Type 1 injuries presented in a delayed manner in 19% of cases, whereas no type 2 injuries (0%) were delayed in presentation. Type 1 injuries infrequently underwent surgical intervention (19%), whereas 54% of type 2 injuries required surgery. Of those that did not undergo initial surgical management at a minimum of 3-month radiographic follow-up, 9/11 (82%) of type 1 injuries and 0/4 (0%) of type 2 injuries demonstrated evidence of healing. Only 1 case required reoperation (type 2 injury). CONCLUSIONS: This series of adolescents with sublime tubercle avulsion injuries expands our understanding of the epidemiology of this rare injury, which was previously only described as a noncontact injury in baseball players. Type 1 injuries are more likely to occur via a noncontact mechanism and generally demonstrate radiographic evidence of healing after a period of rigid immobilization. Conversely, type 2 injuries are more likely to undergo initial surgical intervention, and those managed nonoperatively are less likely to achieve radiographic healing. Further studies are needed to elucidate treatment protocols and long-term functional outcomes. LEVEL OF EVIDENCE: Level IV-case series.

BACKGROUND: Studies have demonstrated that pediatric patients have an increased risk of failure with allograft anterior cruciate ligament reconstruction (ACLR); however, there is no study investigating whether allograft ACLR may be safe in older adolescent patients who are not returning to competitive pivoting sports (ie, low risk). The purpose of this study was to assess outcomes for low-risk older adolescents selected for allograft ACLR. METHODS: We performed a retrospective chart review of patients younger than 18 years who received a bone-patellar-tendon-bone allograft or autograft ACLR by a single orthopaedic surgeon from 2012 to 2020. Patients were offered allograft ACLR if they did not intend to return to pivoting sports for 1 year. The autograft cohort was matched 1:1 based on age, sex, and follow-up. Patients were excluded for skeletal immaturity, multiligamentous injury, prior ipsilateral ACLR, or concomitant realignment procedure. Patients were contacted to obtain patient-reported outcomes at ≥2 years follow-up, including single assessment numerical evaluation, surgery satisfaction, pain scores, Tegner Activity Scale, and the Lysholm Knee Scoring Scale. Parametric and nonparametric tests were used as appropriate. RESULTS: Of the 68 allografts, 40 (59%) met inclusion and 28 (70%) were contacted. Among the 456 autografts, 40 (8.7%) were matched and 26 (65%) were contacted. Two allograft patients (2/40; 5%) failed at a median (interquartile range) follow-up of 36 (12, 60) months. There were 0/40 failures in the autograft cohort and 13/456 (2.9%) among the overall autografts; neither were significantly different from the allograft failure rate (both P > 0.05). Two (5.0%) patients in the autograft cohort required manipulation under anesthesia and arthroscopic lysis of adhesions. There were no significant differences between cohorts for single assessment numerical evaluation, Lysholm, Tegner, pain, and satisfaction scores (all P > 0.05). CONCLUSIONS: Although ACL allograft failure rates remain nearly two times higher than autograft failure rates in older adolescents, our study suggests that careful patient selection can potentially bring this failure rate down to an acceptable level. LEVEL OF EVIDENCE: Level III; retrospective matched cohort study.

BACKGROUND: Anterior cruciate ligament (ACL) injuries in adults are frequently accompanied by meniscal and articular cartilage damage. However, little is known regarding the association, if any, between physical maturity, hypermobility, or bone bruising and these associated injuries in skeletally immature patients with ACL tears. PURPOSE: To determine if physical maturity, hypermobility, and/or bone bruising is associated with concomitant meniscal and articular cartilage injury in skeletally immature patients with ACL tears. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: At 10 institutions in the United States, consecutive skeletally immature patients with complete ACL tears were enrolled between January 2016 and June 2020. Univariable and multivariable logistic regression analysis was used to assess the effect of variables on the likelihood of articular cartilage and meniscal injury. RESULTS: A total of 748 patients were analyzed. Of these, 85 patients (11.4%) had articular cartilage injuries. These patients had a higher bone age (13.9 vs 13.1 years; P = .001), a higher Tanner stage (P = .009), and increased height (162.9 vs 159.9 cm; P = .03) and were heavier (57.8 vs 54.0 kg; P = .02). For each additional Tanner stage, the odds of articular cartilage injury increased approximately 1.6 times (P < .001). Of the total patients, 423 (56.6%) had meniscal tears. Those with meniscal tears were older (12.6 vs 12.0 years; P < .001), had a higher bone age (13.5 vs 12.8 years; P < .001), had a higher Tanner stage (P = .002), had increased height (162.2 vs 157.6 cm; P < .001), and were heavier (56.6 vs 51.6 kg; P < .001). For each additional Tanner stage, the odds of a meniscal tear increased approximately 1.3 times (P < .001). No association was detected between hypermobility or bone bruising and the likelihood of articular cartilage or meniscal injury. Multivariable regression revealed that increasing Tanner stage was associated with an increasing risk of articular cartilage injury, while weight was associated with an increasing risk of meniscal injury. CONCLUSION: Increasing physical maturity is associated with increased risks of concomitant articular cartilage and meniscal injury in skeletally immature patients with ACL tears. Hypermobility and bone bruising are not associated with articular cartilage or meniscal injury, suggesting that physical maturity, rather than ligamentous laxity, is the primary risk factor for associated injuries in skeletally immature patients with an ACL tear.

INTRODUCTION: Forearm fractures are a common pediatric injury. Currently, there is no consensus on treatment for fractures that recur following initial surgical fixation. The objective of this study was to investigate the subsequent fracture rate and patterns and describe the treatment of these forearm fractures. METHODS: We retrospectively identified patients who underwent surgical treatment for an initial forearm fracture at our institution between 2011 and 2019. Patients were included if they sustained a diaphyseal or metadiaphyseal forearm fracture that was initially treated surgically with a plate and screw construct (plate) or elastic stable intramedullary nail (ESIN), and if they subsequently sustained another fracture that was treated at our institution. RESULTS: A total of 349 forearm fractures were treated surgically with ESIN or a plate fixation. Of these, 24 sustained another fracture, yielding a subsequent fracture rate of 10.9% for the plate cohort and 5.1% for the ESIN cohort ( P =0.056). The majority of plate refractures (90%) occurred at the proximal or distal plate edge, while 79% of the fractures treated previously with ESINs occurred at the initial fracture site ( P <0.001). Ninety percent of plate refractures required revision surgery, with 50% underwent plate removal and conversion to ESIN, and 40% underwent revision plating. Within the ESIN cohort, 64% were treated nonsurgically, 21% underwent revision ESINs, and 14% underwent revision plating. Tourniquet time for revision surgeries were shorter for the ESIN cohort (46 vs. 92 min; P =0.012). In both cohorts, all revision surgeries had no complications and healed with evidence of radiographic union. However, 9 patients (37.5%) underwent implant removal (3 plates and 6 ESINs) after subsequent fracture healing. CONCLUSIONS: This is the first study to characterize subsequent forearm fractures following both ESIN and plate fixation and to describe and compare treatment options. Consistent with the literature, refractures following surgical fixation of pediatric forearm fractures may occur at a rate ranging from 5% to 11%. ESINs are both less invasive at the time of initial surgery and can often be treated nonoperatively if there is a subsequent fracture, while plate refractures are more likely to be treated with a second surgery and have a longer average surgery time. LEVEL OF EVIDENCE: Level IV-retrospective case series.

BACKGROUND: Meniscal ramp lesions are associated with anterior cruciate ligament (ACL) injuries and may affect knee stability when left untreated. The diagnostic accuracy of magnetic resonance imaging (MRI) to identify this meniscocapsular injury of the posterior horn of the medial meniscus remains poor, and the arthroscopic findings require vigilance. PURPOSE: To determine the concordance of arthroscopic and MRI findings to better identify the presence of a ramp lesion in children and adolescent patients undergoing primary ACL reconstruction. STUDY DESIGN: Cohort study (diagnosis); Level of evidence, 2. METHODS: Patients aged <19 years who underwent primary ACL reconstruction at a single institution between 2020 and 2021 were included. Two cohorts were developed by the presence of a ramp lesion arthroscopically. Basic patient descriptive data, preoperative imaging (radiologist assessment and independent reviewer assessment), and concomitant arthroscopic findings at the time of ACL reconstruction were recorded. RESULTS: An overall 201 adolescents met criteria with a mean age of 15.7 years (range, 6.9-18.2) at the time of injury. A ramp lesion was identified in 14% of patients (28 children). No differences were detected between cohorts with regard to age, sex, body mass index, weeks from injury to MRI, or weeks from injury to surgery (P > .15). The primary predictor of an intraoperative ramp lesion was the presence of medial femoral condylar striations, with an adjusted odds ratio of 722.2 (95% CI, 59.5-8768.2; P < .001); the presence of a ramp lesion on MRI had an adjusted odds ratio of 11.1 (95% CI, 2.2-54.8; P = .003). Patients with neither a ramp lesion on MRI nor medial femoral condylar striations had a 2% rate (2/131) of ramp lesion; those with either of the significant risk factors had a 24% rate (14/54). All patients with both risk factors (100%; n = 12) had a ramp lesion noted on intraoperative examination. CONCLUSION: The concordance of medial femoral condylar chondromalacia, particularly striations, noted during arthroscopy and posteromedial tibial marrow edema on MRI with or without direct evidence of posterior meniscocapsular pathology should increase suspicion for the presence of a ramp lesion in adolescents undergoing ACL reconstruction.

BACKGROUND: Once a child has developed chronic ankle instability with recurrent events despite conservative treatment, then ligamentous repair is warranted. We utilize a modification of the modified Broström-Gould technique that further incorporates the distal fibular periosteum into the construct. The purpose of this study was to describe the intermediate-term outcomes of our modified Broström-Gould technique for chronic lateral ankle instability in childhood athletes. METHODS: A retrospective review of children who underwent the surgical technique over a 10-year time period (2010 to 2019) was performed, excluding those with <2 years of follow-up. Demographic, surgical, and clinical data were recorded, as well as outcome scores: (1) the Marx activity scale, (2) University of California, Los Angeles activity score, and (3) foot and ankle outcomes score. Recurrent instability events, repeat surgeries, satisfaction with the surgical experience, and return to sport (if applicable) were also recorded. RESULTS: Forty-six children (43 females) with 1 bilateral ankle met the criteria with a mean age at surgery of 14.8 years, and a mean follow-up duration of 4.9 years. The mean Marx activity score was 9.0±5.1, the mean University of California, Los Angeles score was 8.3±1.8, and the mean total foot and ankle outcomes score was 84.0±15.6. Twenty-six ankles (55.3%) reported having at least 1 recurrent episode of instability and 6 of the ankles (12.8%) underwent revision surgery between 3.5 months and 6.5 years of the index procedure. Thirty-nine (84.8%) patients responded that they would undergo our surgery again. CONCLUSION: A modified Broström-Gould procedure can be performed in children with the incorporation of the adjacent periosteum, but recurrence of instability is distinctly possible with longer follow-up with a risk for revision surgery despite good subjective outcomes.

BACKGROUND: Although current clinical practice guidelines from the American Academy of Orthopaedic Surgeons suggest that Type II and III supracondylar humerus (SCH) fractures be treated by closed reduction and pin fixation, controversy remains as to whether type IIa fractures with no rotation or angular deformity require surgery. The purpose of our study was to prospectively compare radiographic and functional outcomes of type IIa SCH fractures treated with or without surgery. METHODS: Between 2017 and 2019, 105 patients between 2 and 12 years of age presenting with type IIa SCH fractures and without prior elbow trauma, neuromuscular or metabolic conditions, were prospectively enrolled. Ten orthopaedic surgeons managed the patients with 5 preferring surgical treatment and 5 preferring an initial attempt at nonoperative treatment. Patients in the nonoperative cohort were managed with a long-arm cast and close radiographic follow-up. Patients underwent a standardized protocol, including 3 to 4 weeks of casting, bilateral radiographic follow-up 6 months postinjury, and telephone follow-up at 6, 12, and 24 months. RESULTS: Ninety-nine patients met the inclusion criteria (45 nonoperative and 54 operatives). Of the nonoperative patients, 4 (9%) were converted to surgery up to their first clinical follow-up. No differences were identified between the cohorts with respect to demographic data, but patients undergoing surgery had on average 6 degrees more posterior angulation at the fracture site preoperatively (P<0.05). At the final clinical follow-up (mean=6 mo), the nonoperative group had more radiographic extension (176.9 vs 174.4 degrees, P=0.04) as measured by the hourglass angle, but no other clinical or radiographic differences were appreciated. Complications were similar between the nonoperative and operative groups: refracture (4.4 vs 5.6%), avascular necrosis (2.2 vs 1.9%) and infection (0 vs 1.9%) (P>0.05). Patient-reported outcomes at a mean of 24 months showed no differences between groups. CONCLUSION: Contrary to American Academy of Orthopaedic Surgeons guidelines, about 90% of patients with type IIa supracondylar fractures can be treated nonoperatively and will achieve good radiographic and functional outcomes with mild residual deformity improving over time. Patients treated nonoperatively must be monitored closely to assess for early loss of reduction and the need for surgical intervention.

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.

BACKGROUND: Elastic intramedullary nails (EINs) are the treatment of choice for school-age children (5 to 12) with diaphyseal femur fractures. Previous literature suggests that EINs are an effective treatment for stable fracture patterns, but may be inadequate for unstable fracture patterns. The purpose of this study was to evaluate whether patients with length unstable fractures had a higher complication rate than those with length stable fractures when treated with EINs. METHODS: All patients with diaphyseal femur fractures treated with EINs over a 22-year period at a single institution were reviewed. Patients were excluded if they had a pathologic fracture, neuromuscular disorder, spinal cord injury with subsequent involvement of affected limb, metabolic bone disease, or if they did not have at least 6-month follow-up. RESULTS: A total of 85 patients with 87 diaphyseal femur fractures treated with EINs were included in the study. In all, 57.5% of the fractures were categorized as length stable and 42.5% were length unstable. Fourteen percent of length stable patients had a residual angular deformity compared with 5.4% of the length unstable group (P=0.24). The length unstable group experienced more shortening at the fracture site than the patients in the length stable group (P=0.003), but no patient required further intervention for their shortening. Two patients in the length stable group experienced overgrowth >2 cm and required subsequent surgery. No relationship was observed between fracture pattern and frequency of complications (length stable 8% vs. length unstable 10.8%, P=0.69). Finally, the knee immobilizer group (10.7%) and the long leg cast group (18.2%) had significantly higher complication rates than the single leg spica cast group (0%, P<0.05). CONCLUSIONS: There was no significant difference in complication rate between length stable and unstable fractures treated with EINs. Adjunctive spica casting may be protective against postoperative complications. While fracture shortening was more likely in the length unstable group, it did not result in increased rate of limb length discrepancy at final follow-up. LEVEL OF EVIDENCE: Level IV, Case Series.

Background: The value of employing an orthopedic technician or advanced practice provider (OT/APP) to assist trainees during on-call hours has not been assessed. As the third most common pediatric long bone fracture, most tibial fractures can be managed with closed reduction and casting. Purpose: We sought to determine whether clinical outcomes could be positively affected for traumatic childhood tibia fractures by using an experienced OT/APP to aid orthopedic surgery residents with closed reduction and casting. Methods: We performed a retrospective chart review of tibial shaft fractures that occurred between 2010 and January 2017. Fractures undergoing manipulation and closed reduction by orthopedic surgery residents (post-graduate year 2 to 4) in the emergency department were included and differentiated into 2 cohorts: (1) residents who performed the procedure alone and (2) residents who were assisted by an OT/APP. Comparisons in cast quality and treatment success were made using univariate statistics followed by a multivariate Classification and Regression Tree (CART) analysis. Results: Of the 73 patients who met our criteria, 38 received treatment by a resident alone and 35 by a resident assisted by an OT/APP. Evidence to support our hypothesis was found with the resident-alone group "over" padding the casts posteriorly. Univariate analysis demonstrated that the rate of subsequent surgical intervention was more than double in the resident-alone group (31% vs 14%), yet OT/APP castings underwent more wedging at follow-up (17% vs 0%). CART analysis revealed initial fracture severity and lack of OT/APP assistance as predictors of surgical intervention with terminal nodes, in increasing order of risk of requiring surgical intervention: lower translation on sagittal and anteroposterior (AP), lower sagittal translation with greater AP translation, greater sagittal translation with OT/APP assistance, and greater sagittal translation without assistance. The initiation of a cast application-training program in 2015 decreased the need for surgical treatment in the resident-only group (pre-program 38.5% vs post-program 17%), although this was not statistically significant. Conclusion: When residents were assisted by OT/APP with initial tibia closed reduction and casting, subsequent loss of reduction was more likely to be managed with cast wedging; when this assistance was not available, there was a higher rate of fractures needing surgical intervention due, in part, to poor casting technique. The reduction in the rate of surgical intervention after an internal training program was implemented suggests that trainees may improve their casting ability without added help of an experienced assistant. Future study should be performed on distal radius fractures to determine if the presented findings are valid across casting types.
RESUMO
BACKGROUND: Osteochondritis dissecans (OCD) occurs most commonly in the knees of young individuals. This condition is known to cause pain and discomfort in the knee and can lead to disability and early knee osteoarthritis. The cause is not well understood, and treatment plans are not well delineated. The Research in Osteochondritis Dissecans of the Knee (ROCK) group established a multicenter, prospective cohort to better understand this disease. PURPOSE: To provide a baseline report of the ROCK multicenter prospective cohort and present a descriptive analysis of baseline data for patient characteristics, lesion characteristics, and clinical findings of the first 1000 cases enrolled into the prospective cohort. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Patients were recruited from centers throughout the United States. Baseline data were obtained for patient characteristics, sports participation, patient-reported measures of functional capabilities and limitations, physical examination, diagnostic imaging results, and initial treatment plan. Descriptive statistics were completed for all outcomes of interest. RESULTS: As of November 2020, a total of 27 orthopaedic surgeons from 17 institutions had enrolled 1004 knees with OCD, representing 903 patients (68.9% males; median age, 13.1 years; range, 6.3-25.4 years), into the prospective cohort. Lesions were located on the medial femoral condyle (66.2%), lateral femoral condyle (18.1%), trochlea (9.5%), patella (6.0%), and tibial plateau (0.2%). Most cases involved multisport athletes (68.1%), with the most common primary sport being basketball for males (27.3% of cases) and soccer for females (27.6% of cases). The median Pediatric International Knee Documentation Committee (Pedi-IKCD) score was 59.9 (IQR, 45.6-73.9), and the median Pediatric Functional Activity Brief Scale (Pedi-FABS) score was 21.0 (IQR, 5.0-28.0). Initial treatments were surgical intervention (55.4%) and activity restriction (44.0%). When surgery was performed, surgeons deemed the lesion to be stable at intraoperative assessment in 48.1% of cases. CONCLUSION: The multicenter ROCK group has been able to enroll the largest knee OCD cohort to date. This information is being used to further understand the pathology of OCD, including its cause, associated comorbidities, and initial presentation and symptoms. The cohort having been established is now being followed longitudinally to better define and elucidate the best treatment algorithms based on these presenting signs and symptoms.

The ideal technique to measure medial epicondyle humerus fracture displacement minimizes radiation exposure while maximizing measurement accuracy and reliability. This study compares the radiation exposure and accuracy of displacement measurements of the four-view X-ray examination (XR), computed tomography (CT) and in-clinic cone-beam CT (CBCT). A cadaveric humerus underwent medial epicondyle osteotomy. The fragment was fixed to the humerus at clinically relevant displacements (6 to 18 mm). Dosimeters were placed around the distal humerus and simulating thyroid location. XR, CT and CBCT were performed at each displacement. Four pediatric orthopedists measured the maximum linear displacement on each XR and 3D reconstruction of the CT and CBCT images. Focal (elbow location) and thyroid radiation exposure was compared between modalities. Intra- and interclass correlation coefficients (ICC) for displacement measurements were determined. Mean focal radiation exposures for XR, CT and CBCT were 0.008, 2.061 and 0.478 rad, respectively (P = 0.001). Exposures 10 inches from the elbow for XR, CT and CBCT were 0.001, 0.066 and 0.010 rad, respectively (P = 0.006). At 12 inches, there was no significant difference in exposure between XR and CBCT ( P = 0.114). Intra- and interobserver reliabilities were excellent for all measures, except lateral x-ray. CBCT and CT had significantly less deviation from the actual displacement compared to XR ( P < 0.05). In-office CBCT of the elbow exposes patients to significantly less radiation than conventional CT. All X-ray images (except lateral), CT and CBCT had equal reliability in evaluating medial epicondyle fractures, which contrasts with previous evidence.
