    ABSTRACT: Background: The emergency room on-call status of pediatric orthopaedic surgeons is an important factor affecting their practices and lifestyles and was last evaluated in 2006. Methods: The entire membership of the Pediatric Orthopaedic Society of North America (POSNA) was surveyed in 2010 for information regarding their emergency room on-call status with 382 surveys returned of over 1000 e-mailed to members of POSNA. Detailed information about on-call coverage, support, and frequency was obtained in answers to 14 different questions. Results: Compared with the prior survey in 2006, the 2010 survey indicated that a higher percentage of pediatric orthopaedic surgeons receive compensation for taking emergency room call; a higher percentage cover pediatric patients only when on-call; and accessibility to operating rooms in a timely manner for trauma cases, although limited, has improved for pediatric patients. Utilization of support staff to meet on-call trauma coverage demands, such as residents, physician's assistants, and nurse practitioners, is becoming more common. Conclusions: Concentration of pediatric orthopaedic trauma has increased the coverage demands on pediatric orthopaedists. This has resulted in a change in reimbursement strategies, and allocation of OR time and hospital staffing resources.

    ABSTRACT: Background: Previous studies investigating the causes of clubfoot have shown conflicting results, potentially because of retrospective study designs or incomplete assessment of causative factors. The study aim was to examine risk factors for clubfoot in a large prospective Norwegian cohort. Methods: Exposures prior and during pregnancy were identified through the Norwegian Mother and Child Cohort Study (MoBa) conducted by the Norwegian Institute of Public Health. This was linked to the Norwegian Medical Birth Registry, which provided clubfoot diagnosis through ICD-10 code Q66.0. Logistic regression analysis investigated associations between potential risk factors and development of clubfoot. Results: A total of 121 clubfoot cases were identified; 1.1 per 1000 births. Parental diagnosis of clubfoot [odds ratio (OR): 31.5; 95% confidence interval (CI):9.61-103.3] and cigarette smoking, both in the three months prior to pregnancy (OR:1.82; 95%CI:1.05-3.18) and the first trimester (OR:2.67; 95% CI:1.28-5.55) were associated with clubfoot. Infants with clubfoot had greater solvent exposure (OR:1.66; 95% CI:1.00-2.76). Oligohydramnios, parental age, parental education, parity, maternal anxiety or depression, alcohol use, season of birth did not have statistically significant associations. Conclusions: In addition to parental diagnosis of clubfoot, results confirm the previously reported association between clubfoot and smoking, and counter previous evidence supporting season of birth, parental education, and other risk factors. Further studies are needed to investigate solvent exposure as a risk factor for clubfoot. Exposure to smoke and solvents can be controlled; this study highlights the importance of public health initiatives to limit these exposures both during pregnancy and in those considering conceiving in the future. Level of Evidence: Level I-prospective cohort study.

    ABSTRACT: Background: Pediatric spine trauma often results from high-energy mechanisms. Despite differences in healing potential, comorbidities, and length of remaining life, treatment is frequently based on adult criteria; ligamentous injuries are fused and bony injuries are treated accordingly. In this study, we present short-term results of a select group of adolescent patients treated using percutaneous pedicle screw instrumentation without fusion. Methods: An IRB-approved retrospective review was performed at a level 1 pediatric trauma center for thoracolumbar spine fractures treated by percutaneous pedicle screw instrumentation. Patients were excluded if arthrodesis was performed or if instrumentation was not removed. Demographics, injury mechanism, associated injuries, fracture classification, surgical data, radiographic measures, and complications were collected. Radiographs were analyzed for sagittal and coronal wedge angles and vertebral body height ratio and statistical comparisons performed on preoperative and postoperative values. Results: Between 2005 and 2013, 46 patients were treated surgically. Fourteen patients (5 male, 9 female) met inclusion criteria. Injury mechanisms included 8 motor vehicle collisions, 4 falls, and 2 all-terrain vehicle/motorcycle collisions. There were 8 Magerl type A injuries, 4 type B injuries, and 2 type C injuries. There was 1 incomplete spinal cord injury. Implants were removed between 5 and 12 months in 12 patients and after 12 months in 2 patients. Statistical analysis revealed significant postoperative improvement in all radiographic measures (P<0.05). There were no neurological complications, 1 superficial wound dehiscence, and 2 instrumentation failures (treated with standard removal). At last follow-up, 11 patients returned to unrestricted activities including sports. Average follow-up was 9 months after implant removal and 19.3 months after index procedure. Conclusions: Adolescent thoracolumbar fractures present unique challenges and treatment opportunities different from the adult patient. We present a nonconsecutive series of 14 patients temporarily stabilized with percutaneous pedicle screw fixation for injuries including 3-column fracture dislocations and purely ligamentous injuries. Temporary fusionless instrumentation can provide successful management of select thoracolumbar spine injuries in pediatric trauma patients. Level of Evidence: Level IV-Retrospective case series.

    ABSTRACT: Background: Displaced tibial shaft fractures are common in adolescent patients, yet there is no standardized management strategy. We compared surgical fixation and closed reduction and casting (CRC) of these fractures to assess treatment outcomes and determine predictors of failure. Methods: We retrospectively reviewed all patients aged 12 to 18 who presented with a displaced tibial shaft fracture that required reduction over an 8-year period. Exclusion criteria included open fractures and lack of follow-up to radiographic union or to 6 months from the index procedure. Fractures were initially treated based on surgeon preference either with CRC or with immediate intramedullary nailing. Seventy-four patients met inclusion criteria: 57 were initially managed with CRC and 17 with operative fixation. Radiographic healing was defined as bridging of 3 cortices and adequacy of final alignment was defined as <5 degrees of angular deformity in both planes and <1.0 cm of shortening. Outcomes were analyzed both on intent-to-treat principles and by definitive treatment method. Results: Although all fractures in both groups achieved bony healing, 23 of the 57 patients who underwent CRC failed closed treatment and ultimately required surgery (40.3%). Multivariate analysis of patient and fracture characteristics revealed fracture displacement of >20% (odds ratio=7.8, P<0.05) and the presence of a fibula fracture (odds ratio=5.06, P=0.05) as predictors of closed treatment failure. Patients ultimately managed with intramedullary nailing trended toward increased adequacy of final alignment (92.5% vs. 72.4%, P=0.10) but required longer hospitalization (5.4 vs. 1.9 d, P<0.001) and had a higher incidence of anterior knee pain (20% vs. 0%, P<0.01). There was no significant difference between groups with respect to time to healing. Conclusions: Treatment outcomes between initial operative fixation and closed reduction of displaced tibia fractures in adolescents are similar, but patients must be counseled about the high failure rates with CRC. Predictors of CRC failure include initial fracture displacement and the presence of a fibula fracture-these variables should be considered when selecting a treatment method. Level of Evidence: Level III-Therapeutic study.

    ABSTRACT: Background: The main objective of this study was to retrospectively evaluate the clinical and radiographic outcomes of displaced tibial shaft fractures with intact fibula in children after nonoperative management and operative treatment by elastic stable intramedullary nailing. Methods: A study was performed on 80 consecutive children, 56 males, 24 females from 2 Institutions, with displaced and closed tibial shaft fracture with intact fibula. All patients underwent regular clinical and radiographic follow-up visits for at least 2 years after injury. Results: In total, 26 patients (group A-Institution I) were treated surgically by elastic stable intramedullary nailing and 54 patients (18 patients from group B-Institution I and 36 patients from group C-Institution II) were treated nonoperatively with closed reduction and casting. groups A, B, and C did not significantly differ on sex (P=0.37), side (P=0.54), and fracture site (P=0.14). Valgus deformity was significantly controlled in group A patients only (P=0.001); during follow-up in group B patients (P=0.017), and showed no significant change between pretreatment images and last follow-up in group C patients (P=0.71). Procurvatum deformity was significantly controlled in group A patients only (P=0.001); it showed no significant improvement after conservative treatment in group B (P=0.73) and C patients (P=0.8). Recurvatum was significantly improved in group A (P<0.001) and C patients (P<0.001) but remained unchanged in group B patients (P=0.15). Varus deformity improved significantly in all patient groups. Immobilization time was significantly shorter in group A compared with group B and C patients (P<0.001). However, numerical differences, although statistically significant, were not clinically relevant for all variables but immobilization time. Conclusions: This study showed good functional and radiologic outcomes in the pediatric population who had sustained closed, traumatic, displaced fracture of tibial diaphysis without associated fibula fracture. On the basis of the findings reported here, it is not contraindicated to operate skeletally immature patients with displaced fracture of tibial diaphysis without associated fibula fracture. However, results were essentially the same and either method is a satisfactory choice for pediatric tibia shaft fractures with an intact fibula. In particular, we found that conservative treatment was as efficacious as surgical treatment apart from the length of time for immobilization. Level of Evidence: Level III.

    ABSTRACT: Background: Fractures are a significant concern for individuals with Duchenne/Becker muscular dystrophy with 21% to 44% of males experiencing a fracture. Factors that increase or decrease the risk for fracture have been suggested in past research, although statistical risk has not been determined. Methods: In this retrospective cohort study, we used the Muscular Dystrophy Surveillance, Tracking and Research Network cohort, a large, population-based sample to identify risk factors associated with first fractures in patients with Duchenne or Becker muscular dystrophy. Our study cohort included males with Duchenne or Becker muscular dystrophy born between 1982 and 2006 who resided in Arizona, Colorado, Georgia, Iowa, and Western New York, retrospectively identified and followed through 2010. We utilized a multivariate Cox proportional hazard model to determine hazard ratios for relevant factors associated with first fracture risk including race/ethnicity, surveillance site, ambulation status, calcium/vitamin D use and duration, bisphosphonate use and duration, and corticosteroid use and duration. Results: Of 747 cases, 249 had at least 1 fracture (33.3%). Full-time wheelchair use increased the risk of first fracture by 75% for every 3 months of use (hazard ratio=1.75, 95% confidence interval, 1.14, 2.68), but corticosteroid use, bisphosphonate use, and calcium/vitamin D use did not significantly affect risk in the final adjusted model. Conclusions: In this cohort, first fractures were common and full-time wheelchair use, but not corticosteroid use, was identified as a risk factor. The impact of prevention measures should be more thoroughly assessed. Clinical Relevance: Fractures are a significant concern for individuals with dystrophinopathies, but the contribution of various risk factors has not been consistently demonstrated.

    ABSTRACT: The etiology of slipped capital femoral epiphysis (SCFE) is multifactorial, but the role of sagittal balance of the pelvis as a contributing factor to its development has not been well studied. Our primary purpose was to determine whether a smaller pelvic incidence (PI), a position-independent anatomic parameter that regulates pelvic orientation, could be a factor that increases shear stress in the epiphyseal growth plate and potentially contributes to the development of SCFE. We also set out to determine whether acetabular retroversion was associated with SCFE.

    ABSTRACT: Previous investigation has proven 3-dimensional (3D) computed tomography (CT) to be a poor method of assessing femoral anteversion in patients with cerebral palsy. However, new advancements in CT software yield the potential to improve upon those dated results. CT was performed on 9 femoral models with varying amounts of anteversion (20 to 60 degrees) and varying neck-shaft angles (120 to 160 degrees). Each model was scanned in 2 holding devices. One holder placed the femur in an ideal position relative to the gantry. The other placed the femur in flexion, adduction, and internal rotation simulating a common lower extremity posture in cerebral palsy. Femoral anteversion was measured on 3D reconstructions by 4 observers on 2 separate occasions. Interobserver and intraobserver reliability, accuracy, and the effect of increasing neck-shaft angle of the measurements were examined and compared with previously published data using the same models. Pearson correlation coefficients between first and second measurements by the same examiner were all above 0.96 regardless of positioning of the femur in the gantry. The correlation coefficients among all examiners were 0.97 regardless of positioning of the femur in the gantry. Accuracy in measurements was comparable using 3D CT techniques with mean differences between the normal and cerebral palsy-positioned models of <3.6 degrees (SD, 3.1 to 3.3 degrees). Accuracy of the study's 3D CT technique in measuring femoral anteversion in cerebral palsy-positioned femurs was significantly more accurate than that of 2D CT (P<0.0001). Recent improvements in processing software and 3D reconstruction have made assessment of femoral anteversion with 3D CT accurate through the studied range of anteversion and neck-shaft angles. Using this technique, high intraobserver and interobserver reliability in the determination of femoral anteversion can be expected regardless of neck-shaft angle or postural deformity. Level II.

    ABSTRACT: Three patients with birth fractures and Werdnig-Hoffmann disease are presented. Two of the three were erroneously diagnosed as having osteogenesis imperfecta. The etiology of these fractures appears to be in utero osteoporosis secondary to decreased movement, leading to pathologic fracture during birth. Immobilization led to uneventful healing in all cases; no recurrent fractures were seen.
