RESUMO
PURPOSE: Adolescent idiopathic scoliosis (AIS) is a common spinal deformity with varying progression, complicating treatment decisions. Artificial intelligence (AI) and machine learning (ML) are increasingly prominent in orthopedic care, aiding in diagnosis, risk-stratification, and treatment guidance. This scoping review outlines AI applications in AIS. METHODS: This study followed PRISMA-ScR guidelines and included articles that reported the development, use, or validation of AI models for treating, diagnosing, or predicting clinical outcomes in AIS. RESULTS: 40 full-text articles were included, with most studies published in the last 5 years (77.5%). Common ML techniques were convolutional neural networks (55%), decision trees and random forests (15%), and artificial neural networks (15%). Most AI applications in AIS were for imaging analysis (25/40; 62.5%), focusing on automatic measurement of Cobb angle, and axial vertebral rotation (13/25; 52%) and curve classification/severity (13/25; 52%). Prediction was the second most common application (15/40; 37.5%), with studies predicting curve progression (9/15; 60%), and Cobb angles (9/15; 60%). Only 15 studies (37.5%) reported clinical implementation guidelines for AI in AIS management. 52.5% of studies reported model accuracy, with an average of 85.4%. CONCLUSION: This review highlights the applications of AI in AIS care, notably including automatic radiographic analysis, curve type classification, prediction of curve progression, and AIS diagnosis. However, the current lack of clear clinical implementation guidelines, model transparency, and external validation of studied models limits clinician trust and the generalizability and applicability of AI in AIS management.
RESUMO
INTRODUCTION: Initiation of Pavlik harness treatment for developmental dysplasia of the hip (DDH) by 6 to 7 weeks of age predicts a higher rate of success. Child Opportunity Index (COI) 2.0 is a single metric designed to measure resources and conditions affecting children's healthy development. This study investigates COI in relation to the timing of DDH diagnosis. METHODS: This is a retrospective cohort study on patients younger than 4 years diagnosed with DDH between 2016 and 2023, treated with a Pavlik harness, rigid hip abduction orthosis, and/or surgery. Demographic and clinical data were recorded, including date of first diagnostic imaging. Patients with syndromes, congenital anomalies, or neuromuscular disorders and those referred with an unknown date of first diagnostic imaging were excluded. A subgroup analysis of patients diagnosed at ≤6 weeks ("early") and >6 weeks ("late") was conducted. Statewide COI scores (total, three domains) and categorical quintile scores (very low, low, moderate, high, and very high) were recorded. RESULTS: A total of 115 patients were included: 90 female infants (78%), with a median age of 32 days at diagnostic imaging. No notable difference was observed between median age at diagnosis for study patients in low or very low quintiles and those in moderate, high, or very high quintiles for COI total or domains. "Early" and "late" diagnosis subgroups did not differ markedly by COI total or domains, nor insurance type, race, or ethnicity. Subgroups differed markedly by race and insurance status. DISCUSSION: In an urban children's hospital, COI did not differ markedly between patients diagnosed with DDH by ≤6 weeks and >6 weeks. This is the first study to pose this question on DDH in a population with predominantly low/very low COI scores and public insurance, which may lead to unexpected results. Replicating the study in a different setting could yield different results. LEVEL OF EVIDENCE: III.

Objectives: Physeal drilling and curettage (PDC) and percutaneous epiphysiodesis using transphyseal screws (PETS) are among the most widely used techniques to treat leg-length discrepancy (LLD). This study compared the efficacy and outcomes between PETS alone and PETS combined with PDC (PETS + PDC). Methods: Retrospective study of children who underwent epiphysiodesis of the proximal tibia or distal femur with either PETS or PETS + PDC between 2008 and 2018 at a single institution. Radiographic parameters and complications were reviewed at completion of treatment and most recent follow-up. Results: A total of 23 epiphysiodeses in 15 patients, average age 13.1 years, with either PETS (13 femur/tibias) or PETS + PDC (10 femur/tibias) were included. PETS patients were treated for a longer time (median: 24 months vs 11 months, p = 0.004), however, follow-up time was similar between groups (p = 0.577), on average 2.7 years. In the PETS group, LLD decreased from 2.55 to 0.84 cm at most recent follow-up (p = 0.010), and in the PETS + PDC group from 3.01 to 1.2 cm (p = 0.005), achieving a correction of 1.71 cm for PETS and 1.83 cm for PETS + PDC (p = 0.871). A correction of LLD to ≤ 2 cm was achieved in 8 PETS (89%) and 4 PETS + PDC cases (67%) (p = 0.525). Two PETS patients (22%) and 1 PETS + PDC (17%) patient returned to the OR for further correction due to persistent LLD (p = 1.000). No differences existed in total number of complications, angular deformity or return to physical activity between groups (p ≥ 0.05 for each comparison). Conclusions: This study showed equal efficiency in resolving LLD between the PETS and PETS + PDC procedures with minimal operative complications.Level of Evidence III.
RESUMO
BACKGROUND AND OBJECTIVES: Inpatient postoperative care is reliant upon clear, open communication between providers and patient-families, and thus is particularly vulnerable to disparities when discordant languages exist. It is not yet understood how standardized postoperative protocols may mitigate disparities related to language discordance. METHODS: This is a retrospective cohort study among adolescent idiopathic scoliosis patients who underwent posterior spinal fusion at a tertiary care children's hospital in Bronx, New York after implementation of a postoperative pathway in 2017. Outcomes reliant upon communication between patient-families and providers were measured, including measures of pain management (number and type of pain medications requested, daily pain assessments, total opioids consumed), as well as outpatient pain scores. RESULTS: A total of 160 patients were included (39 language other than English [LOE]). Between patient cohorts, there were no significant differences in demographic or operative characteristics. On univariate analyses, LOE patients were more likely to be given a basal dosing of patient-controlled analgesia or additional boluses (26% vs 12%, P = .03), consumed 0.53 fewer benzodiazepine medications per day (P = .01), and were more likely to have pain at outpatient follow-up (67% vs 43%, P = .03). On multivariate analyses, LOE patients were more likely to be placed on basally dosed or receive additional boluses of patient-controlled analgesia (odds ratio 3.19, 95% confidence interval 1.15-8.85). CONCLUSIONS: As standardized pathways become more common in health care, it is critical to monitor for components of these protocols that may be vulnerable to language-related disparities, such as therapies reliant on symptom description and outpatient follow-up.

OBJECTIVES: The best effective treatment strategy for limb length discrepancy (LLD) is still being debated. The goal of this study was to compare the efficacy and results of tension-band plating (TBP) and percutaneous epiphysiodesis using transphyseal screws (PETS) for LLD correction. METHODS: From June 2008 to January 2019, children who had lower extremity epiphysiodesis with either TBP or PETS were reviewed retrospectively. At the conclusion of treatment, LLD, angular deformity, and complications were reviewed. The t-test or Wilcoxon rank sum test was used to compare continuous variables. Categorical variables were evaluated using Fisher's exact test or χ2 test. RESULTS: A total of 32 epiphysiodeses with TBP (14 patients, 24 femur/tibias) or PETS (13 patients, 23 femur/tibias) were compared. TBPs were conducted while the patients were younger (11.0 vs. 13.1 years, p = 0.005). The treatment durations were similar in both groups (TBP: 23.5 months vs. PETS: 24 months, p = 0.132). PETS had significantly shorter operative time (p = 0.047), length of hospital stay (p = 0.014), and time to return to full activity (p = 0.043). LLD in the TBP group reduced from 2.64 to 1.38 cm (p = 0.005), while in the PETS group it decreased from 2.76 to 1.08 cm (p = 0.001). During treatment, the rate of LLD correction was 0.49 ± 0.9 cm/year for limbs treated with TBP and 1.0 ± 1.1 cm/year for limbs treated with PETS (p = 0.185). At the end of treatment, 8 TBP cases (47%) and 9 PETS cases (60%) had achieved LLD ≤ 2 cm (p = 0.502), and at the most recent follow-up, this had grown to 11 (65%) in the TBP group and 12 (80%) in the PETS group. There were no significant differences in the total number of complications between groups (p > 0.05). Revision surgery was required in 11 TBP and 3 PETS limbs due to persistent LLD or angular deformity (AD) (p = 0.016). Logistic regression did not reveal any significant association between TBP and the rate of complication or revision surgery. CONCLUSION: PETS and TBP are both effective methods for limb length equalization. PETS, on the other hand, was linked to a shorter operative time, a shorter hospital stay, a faster recovery to pre-operative function, and a lower complication rate. The rate of revision surgery due to persistent LLD or AD was higher in TBP. We advise surgeons against utilizing TBP to correct LLD. LEVEL OF EVIDENCE: III.

BACKGROUND: The primary objective of the Pediatric Orthopaedic Society of North America (POSNA)-Children's Orthopaedics in Underserved Regions (COUR) Visiting Scholar Program is to engage emerging leaders from low-income and middle-income countries (LMICs) in POSNA educational offerings. This study aims to outline the educational and leadership activities pursued by the alumni of the POSNA-COUR Visiting Scholars Program. We hypothesized that there may be a discrepancy between visiting scholar interest level and actual participation in key follow-up educational and leadership activities. METHODS: A 32-question online survey developed by the POSNA-COUR committee was electronically delivered to the POSNA-COUR visiting scholarship recipients from 2007 to 2019. The survey inquired about scholars' educational background, clinical practice, and academic interests. Respondents also reported educational, research, and leadership activities that occurred following program participation. RESULTS: Fifty-seven percent (44/77) of the previous scholars participated in the survey. Sixty-eight percent reported that >75% of their practice was comprised of pediatric patients. The COUR scholarship afforded 15 scholars the opportunity to attend their first educational conference in North America. The majority (86%) of respondents consulted POSNA members on care-related issues, 52% organized a POSNA member's visit to their country, and 13% have become members of POSNA. Scholars shared their knowledge with colleagues through lectures (73%), demonstration of surgical skills (63%), mentorship (59%), hosting local courses (43%), and research (14%). There was a significant discrepancy between interest and actual participation in research (98% vs. 16%, P<0.0001), hosting a regional course (98% vs. 43%, P<0.0001), and becoming a member of POSNA (96% vs. 13%, P<0.0001). CONCLUSIONS: The POSNA-COUR Visiting Scholar Program is effective at providing beneficial educational opportunities to orthopaedic surgeons from LMICs. There is, however, a significant discrepancy between reported scholar interest and actual engagement in leadership endeavors including: research, organization of regional courses, and POSNA membership. The impact of the POSNA-COUR visiting scholar program can be enhanced through collaboration with scholarship alumni in these key areas. LEVEL OF EVIDENCE: Level IV-case series.

The consequences of sickle cell disease (SCD) include ongoing hematopoietic stress, hemolysis, vascular damage, and effect of chronic therapies, such as blood transfusions and hydroxyurea, on hematopoietic stem and progenitor cell (HSPC) have been poorly characterized. We have quantified the frequencies of nine HSPC populations by flow cytometry in the peripheral blood of pediatric and adult patients, stratified by treatment and control cohorts. We observed broad differences between SCD patients and healthy controls. SCD is associated with 10 to 20-fold increase in CD34dim cells, a two to five-fold increase in CD34bright cells, a depletion in Megakaryocyte-Erythroid Progenitors, and an increase in hematopoietic stem cells, when compared to controls. SCD is also associated with abnormal expression of CD235a as well as high levels CD49f antigen expression. These findings were present to varying degrees in all patients with SCD, including those on chronic therapy and those who were therapy naive. HU treatment appeared to normalize many of these parameters. Chronic stress erythropoiesis and inflammation incited by SCD and HU therapy have long been suspected of causing premature aging of the hematopoietic system, and potentially increasing the risk of hematological malignancies. An important finding of this study was that the observed concentration of CD34bright cells and of all the HSPCs decreased logarithmically with time of treatment with HU. This correlation was independent of age and specific to HU treatment. Although the number of circulating HSPCs is influenced by many parameters, our findings suggest that HU treatment may decrease premature aging and hematologic malignancy risk compared to the other therapeutic modalities in SCD.

INTRODUCTION: Management of pathological fractures of the proximal femur is often challenging. Compound double-plate osteosynthesis has been specifically developed for surgical treatment of these pathological fractures. To our knowledge, this study represents the largest series to date of double-plate compound osteosynthesis with the longest follow-up. MATERIALS AND METHODS: Using our institutional digital database, we identified 61 procedures in 53 patients at the proximal femur. Patients were divided into two groups. A 'primary' group with all cases in which a double-plate compound osteosynthesis was performed as initial procedure (n = 46) and a 'revision' group with all cases in which a double-plate compound osteosynthesis was performed as revision procedure after failed previous attempts of internal fixation (n = 15). (1) The survivorship of the hip was calculated using the Kaplan-Meier survivorship analysis. (2) Complications were graded using Sink's classification. (3) The functional outcome was quantified with the Merle d'Aubigné and Postel score. (4) Risk factors were identified based on a multivariate Cox-regression analysis. RESULTS: The cumulative Kaplan-Meier survivorship of the primary group was 96% at 6 months, 90% at 1 year, 5 years and thereafter and 83% at 6 months, 74% at 1 year, 53% at 2 years for the 'revision' group (p = 0.0008). According to the classification of Sink et al., the rate of grade III and IV complications was significantly lower in the primary group (p < 0.0001). The mean Merle d'Aubigné score was 14 ± 7 at 0-3 months, 13 ± 3 at 3-6 months, 15 ± 3 at 6-12 months and 15 ± 4 thereafter (p = 0.54). The only multivariate negative predictor was previous surgery with a hazard ratio of 9.2 (p < 0.006). CONCLUSION: Double-plate compound osteosynthesis is a valuable treatment option for pathological fractures in proximal femur with good functional results.

Over the past 5 years, published literature regarding treatment of pediatric limb deformity and limb length discrepancy demonstrates much interest in better understanding, categorizing and treating these challenging problems. Many studies explore expanding and refining indications for traditional treatment methods like guided growth techniques. Other studies have evaluated the results of new techniques such as lengthening via mechanized intramedullary nails. Additionally, series comparing older and newer techniques such as lengthening with external devices versus mechanized nails are becoming increasingly available.

OBJECTIVE: Evaluation of a child's intoeing gait is one of the most common referrals made to a pediatric orthopedist. Families may have difficulty understanding the often transient and usually benign nature of intoeing. The purpose of this study was to investigate parental perceptions of an intoeing gait both before and after consultation with an orthopedic practitioner. METHODS: 48 parents of children referred to pediatric orthopedic surgeons for evaluation of intoeing gait completed a 22-item questionnaire that assessed demographics, anxiety, and parental perceptions of intoeing. Questionnaires were administered before and after visits. Statistical analysis was performed using Wilcoxon signed-rank tests and Fisher exact tests. RESULTS: Before their visits, parents reported similar levels of anxiety and understanding regarding intoeing, independent of their age or education. After the visits, anxiety decreased (P < 0.001), and understanding increased (P < 0.001) although younger parents (18-25 years) reported higher post-visit anxiety compared to parents older than 25 (P = 0.014). Similarly, parents with a high school degree or less reported higher post-visit anxiety compared to parents who attended college (P = 0.009). Post-visit understanding was inversely correlated with post-visit anxiety (r = -0.717; P < 0.001). Additionally, parents who reported high anxiety post-visit stated they were more likely to seek additional care (P < 0.001). CONCLUSIONS: Younger parents with lower education levels were more likely to leave visits with high anxiety and poor understanding. These parents were more likely to consider seeking further treatment for their child's intoeing, placing additional stress on their child, themselves and an overburdened healthcare system.

With the increasing popularity of hoverboards in recent years, multiple centers have noted associated orthopaedic injuries of riders. We report the results of a multi-center study regarding hoverboard injuries in children and adolescents. who presented with extremity fractures while riding hoverboards to 12 paediatric orthopaedic centers during a 2-month period were included in the study. Circumstances of the injury, location, severity, associated injuries, and the required treatment were recorded and analysed using descriptive analysis to report the most common injuries. Between-group differences in injury location were examined using chi-squared statistics among (1) children versus adolescents and (2) males versus females. Seventy-eight patients (M/F ratio: 1.8) with average age of 11 ± 2.4 years were included in the study. Of the 78 documented injuries, upper extremity fractures were the most common (84.6%) and the most frequent fracture location overall was at the distal radius and ulna (52.6%), while ankle fractures comprised most of the lower extremity fractures (66.6%). Majority of the distal radius fractures (58.3%) and ankle fractures (62.5%) were treated with immobilization only. Seventeen displaced distal radius fractures and three displaced ankle fractures were treated with closed reduction in the majority of cases (94.1% versus 66.7%, respectively). The distal radius and ulna are the most common fracture location. Use of appropriate protective gear such as wrist guards, as well as adult supervision, may help mitigate the injuries associated with the use of this device; however, further studies are necessary to demonstrate the real effectiveness of these preventions.

BACKGROUND: The recent use of ultrasound elastography to study patellar tendon softness has demonstrated increased tendon softness in high-level athletes. We hypothesized that measurable alterations in patellar tendon softness may be present in young asymptomatic subjects engaging in moderate levels of physical activity. METHODS: This was a cross-sectional study. Gray-scale ultrasound and ultrasound elastography of the right and left patellar tendons were performed in young asymptomatic sedentary subjects and moderately active subjects who engaged in at least 30â¯min of physical activity 4-5 times weekly. The distribution of soft, intermediate and stiff tissue within each tendon was analyzed. Tendon softness was correlated with subject age, gender and level of athletic activity. RESULTS: Sixty patellar tendons in 30 subjects were evaluated (18 males, 12 females, mean age 22.5â¯years). Seventeen subjects were defined as "active" and 13 as "sedentary." All tendons had a normal gray-scale sonographic appearance. Tendon softness was significantly higher in active subjects (Pâ¯=â¯0.01) and decreased with age (Pâ¯=â¯0.04). In sedentary individuals there was no significant correlation between age and tendon softness (Pâ¯=â¯0.404). Similarly, gender showed no correlation with tendon softness (Pâ¯>â¯0.05). CONCLUSIONS: Patellar tendon softness is higher in young subjects and in those engaging in moderate physical activity. This may reflect an adaptation to increased tendon load. Tendon softness in active subjects decreases with age, while it remains at a constant value in sedentary individuals. LEVEL OF EVIDENCE: Level 3.

BACKGROUND: The Pediatric Orthopedic Society of North America (POSNA)-Children's Orthopedics in Underserved Regions (COUR) International Scholar Program was initiated in 2007 to provide educational opportunities for emerging leaders who treat children with orthopaedic conditions in resource-challenged environments worldwide. Financial support is available each year for 4 to 6 orthopaedic surgeons to attend either the POSNA Annual Meeting or the International Pediatric Orthopedic Symposium. The scholars are also encouraged to visit selected centers for observerships during their trip. Since 2007 there have been 41 international scholars who have participated in the program. We wished to assess the impact of the program and to obtain feedback to improve the experience for future participants. METHODS: A 23-question web-based survey was created and sent to 38 past scholars from 22 countries who have participated in the program by July 2013. The responses were gathered online and the data were analyzed for the 24 (62%) respondents from 18 countries who completed the survey. RESULTS: Of the respondents, 16/24 (66%) reported that their current practice is comprised of at least 75% pediatrics. Twelve of 24 (52%) were fellowship trained in pediatric orthopaedics, typically outside of North America. All scholars found the meeting they attended to be very useful and have subsequently made changes to their clinical practice. Nineteen of 24 (82%) did a premeeting or postmeeting observership. Twenty-two of 24 (92%) participants have remained in contact with POSNA members they met at the meeting, with 86% of respondents stating that they have subsequently consulted POSNA members on management of patients. Sixty-two percent of the scholars had a POSNA member visit them following the scholarship and 29% have since returned to visit POSNA members for further clinical observerships. Twenty-one of 24 (91%) have had the opportunity to share the knowledge they gained with others in their region through lectures, surgical demonstrations, and/or clinical training. A common response from the scholars was that the scholarship program was a truly transformative life experience that provided them with an opportunity to receive the highest quality of professional education. The main challenges that these scholars report are lack of available fellowship/subspecialty training in their region, patients' inability to pay, and excessive physician workload. All of the respondents expressed interest in arranging a POSNA cosponsored regional meeting. CONCLUSIONS: Since 2007, the POSNA-COUR international scholar program has been a fruitful resource for orthopaedists practicing in resource-challenged environments worldwide. It has provided unique training for the scholars and has further enabled them to teach others in their region. The program has thus far succeeded in fostering lasting relationships that have led to continued educational exchanges. LEVEL OF EVIDENCE: Level IV-case series.

BACKGROUND: There are a number of syndromes that have historically been associated with scoliosis e.g.: Marfan, Down, and Neurofibromatosis. These syndromes have been grouped together as one etiology of scoliosis, known as syndromic scoliosis. While multiple studies indicate that these patients are at high risk for perioperative complications, there is a paucity of literature regarding the collective complication rates and surgical needs of this population. METHODS: PubMed and Embase databases were searched for literature encompassing the surgical complications associated with the surgical management of patients undergoing correction of scoliosis in the syndromic scoliosis population. Following exclusion criteria, 24 articles were analyzed for data regarding these complications. RESULTS: The collective complication rates and findings of these articles were categorized based on specific syndrome. The rates and types of complications for each syndrome and the special needs of patients with each syndrome are discussed. Several complication trends of note were observed, including but not limited to the universally nearly high rate of wound infections (>5% in each group), high rate of pulmonary complications in patients with Rett syndrome (29.2%), high rate (>10%) of dural tears in Marfan and Ehlers-Danlos syndrome patients, high rate (>20%) of implant failure in Down and Prader-Willi syndrome patients, and high rate (>25%) of pseudarthrosis in Down and Ehlers-Danlos patients. CONCLUSIONS: Though these syndromes have been classically grouped together under the umbrella term "syndromic," there may be specific needs for patients with each of these ailments. Given the high rate of complications, further research is necessary to understand the unique needs for each of these patient groups in the preoperative, intraoperative, and postoperative settings.
RESUMO
BACKGROUND: Displaced tibial spine fractures are frequently treated with surgical reduction and fixation, but no comparison studies have been performed. This study was undertaken to compare fragment reduction and adverse outcomes between open arthrotomy [open reduction and internal fixation (ORIF)], arthroscopy [arthroscopic-assisted internal fixation (AAIF)], and closed management [closed management and casting (CMC)] of pediatric tibial spine fractures. METHODS: A retrospective review of children treated for displaced tibial spine fractures from 2003 to 2011 was performed after categorizing into the 3 treatment groups. Demographics, mechanism of injury, radiographic measures (plain film and computed tomography), treatment, duration of immobilization and follow-up, final range of motion, and complications were recorded. Families were contacted to obtain long-term Lysholm scores, return to activity, pain, and satisfaction with treatment. RESULTS: Seventy-six children (mean age, 12.4 y) met criteria with 29 ORIF, 28 AAIF, and 19 CMC. Radiographic measurements between x-ray and computed tomography scans found a mean error of 1 mm (SD=1.33 mm; inter-class coefficient = 0.977, P < 0.001). Initial fracture displacement was similar between AAIF and ORIF, 10.3 ± 4.4 mm and 10.8 ± 3.9 mm; but, less in CMC group (5.3 ± 2.6 mm). The mean reduction amount was 8.6 ± 4.7, 9.1 ± 4.0, and 2.3 ± 2.6 mm, respectively. A Bonferroni post hoc analysis revealed a difference between surgical and nonoperative reduction (P < 0.001), but not between AAIF and ORIF (P=0.9). Arthrofibrosis occurred with equal frequency in surgical cohorts (AAIF 12.5%, ORIF 11.1%), compared with none in the CMC group. Yet, the CMC group had a 16.7% risk for reoperation secondary to instability, loose bodies, or impingement. Twenty-four percent of each cohort was available (at mean 6.0 y) for interview with mean (median) Lysholm score: ORIF 97.4 (99), AAIF 95 (100), and CMC 86 (97.5), P = 0.35. CONCLUSIONS: Open or arthroscopic treatment of displaced tibial spine fractures affords a better reduction than closed management, but with higher risk for arthrofibrosis. Closed management may be successful when displacement is < 5 mm, and advanced imaging may not be necessary to delineate the amount of displacement.

BACKGROUND: Obese children reportedly have an increased risk of sustaining musculoskeletal injuries compared with their normal-weight peers. Obese children are at greater risk for sustaining fractures of the forearm, particularly from low-energy mechanisms. Furthermore, obesity is a risk factor for sustaining an extremity fracture requiring surgery. However, it is unclear what role obesity plays in fractures about the distal humerus. QUESTIONS/PURPOSES: We therefore asked whether (1) children who sustain lateral condyle (LC) fractures have a higher body mass index (BMI) as compared with those with supracondylar (SC) humerus fractures; and (2) children with a higher BMI sustain more severe fractures regardless of fracture pattern. METHODS: We retrospectively reviewed 992 patients: 230 with LC injuries and 762 with SC fractures. We determined BMI and BMI-for-age percentiles. Fracture types were classified by the systems proposed by Weiss et al. (LC fractures) and Wilkins (SC fractures). RESULTS: The LC group had both a higher mean BMI and BMI-for-age percentile than the SC group as well as had more obese patients (37% versus 19%). Within the LC group, children with Type 3 fractures had a higher BMI that those with Type 1 fractures (19 versus 17). There was a higher percentage of obese patients with Type 3 LC fractures compared with Type 1 and 2 fractures (44% versus 27% and 26%). Among patients with SC fractures, there was no difference among the BMI, BMI-for-age percentiles, or percentage of obese children when analyzed by fracture subtype. CONCLUSIONS: Obesity places a child at greater risk for sustaining a LC fracture and when these fractures occur, they are often more severe injuries compared with those in nonobese children. LEVEL OF EVIDENCE: Level II, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.
