Background: Closed reduction and percutaneous pin fixation is the treatment of choice for completely displaced (type-III) extension supracondylar fractures humerus in children, although controversy persists regarding optimal pin-fixation technique. The purpose this study was to compare efficacy lateral entry with that medial operative children. Methods: This prospective, randomized clinical trial had sufficient power detect a 10% difference rate loss between two groups. techniques were...
In Brief Study Design. Retrospective review of a radiographic database high-grade spondylolisthesis patients in comparison with asymptomatic controls. Objective. To analyze the sagittal spinopelvic alignment and identify subgroups that may require reduction to restore balance. Summary Background Data. High-grade is associated an abnormally high pelvic incidence (PI); however, spatial orientation pelvis, determined by sacral slope (SS) tilt (PT), not known. We hypothesized spinal would vary...
Meniscal entrapment under a displaced tibial eminence fragment may be rationale for arthroscopic or open reduction in type 2 and 3 fractures.To determine the prevalence of meniscal children with fractures.Case series.Records consecutive series 80 skeletally immature patients (mean age, 11.6 years; range, 5 to 16) who underwent (71), (5), combined (4) internal fixation fractures (57) that did not reduce extension (23) from 1993 2001 were reviewed.Entrapment anterior horn medial meniscus (36),...
Background: Tranexamic acid (TXA) is an antifibrinolytic drug that reduces surgical blood loss. Evidence supporting its efficacy in surgery for adolescent idiopathic scoliosis not robust. This trial was designed to validate the clinical of TXA scoliosis. Methods: institutional review board-approved prospective double-blinded involved 111 patients with who were randomized receive either a placebo or (50-mg/kg loading dose and 10-mg/kg/h infusion). Power analysis indicated 50 per group would...
PURPOSE: To demonstrate the magnetic resonance (MR) imaging characteristics of patellar sleeve fracture, a cartilaginous avulsion from lower pole patella occurring during forceful contraction quadriceps muscle against partially flexed knee. MATERIALS AND METHODS: The authors evaluated radiographs and MR images three children with suspected fractures. RESULTS: Radiographs showed small bone fragments avulsed in two no abnormality one. demonstrated separation most all children, definite...
Objective. Delay in diagnosis of slipped capital femoral epiphysis (SCFE) has important implications terms slip severity and long-term hip outcome. The purpose this study was to identify predictors delay the SCFE. Methods. A review 196 patients with SCFE performed. primary outcome measure from onset symptoms diagnosis. Covariates included age, gender, side, weight, pain location, insurance status, family income, severity, stability. not normal distribution; therefore, nonparametric...
The purpose of this study was to determine the prevalence peripheral rim instability in discoid lateral meniscus. A consecutive series 112 patients (128 knees) (mean age 10.0 years [range 1 month 22 years]) who underwent arthroscopic evaluation and treatment a meniscus between 1993 2001 reviewed. Of those menisci classified intraoperatively (n = 87), 62.1% 54) were complete 37.9% 33) incomplete menisci. An associated meniscal tear present 69.5% 89) all knees studied. Overall, 28.1% 36) had...

Background: Management of pediatric radial neck fractures is controversial regarding acceptable alignment, variable reduction techniques, and suboptimal outcomes. The purpose this study was to assess the characteristics, management, results in a surgical cohort, efforts identify prognostic factors offer treatment suggestions. It hypothesized that less invasive maneuvers would precede open worse correlate with fracture severity, reduction, presence associated injuries. Methods: Retrospective...

Background: The management of the contralateral hip after unilateral slipped capital femoral epiphysis is controversial. purpose this study was to determine, with use expected-value decision analysis, optimal strategy—prophylactic in situ pinning versus observation—for hip. Methods: Outcome probabilities were determined from a systematic review literature. Utility values obtained questionnaire on patient preferences completed visual analog scale by twenty-five adolescent male patients...
Proliferative lesions of the bone surface, such as subungual (Dupuytren) exostosis and bizarre parosteal osteochondromatous proliferation (BPOP, Nora lesion) are currently classified reactive, proliferative processes that mimic primary neoplasms bone.Cytogenetic analysis was performed on 3 exostoses great toe 2 BPOP radius ulna.A balanced translocation t(X;6) identified in all cases exostoses. The chromosomal rearrangements observed 1 case differed from those seen exostosis.The presence...
Background Spica cast immobilization remains the treatment of choice for femur fractures in children aged 6 months to years. The incidence skin complications and their associated charges have not been well described. This study's purposes were to: (1) determine rate treated with spica casts fractures, (2) identify predictors, (3) calculate complications. Methods Health records all patients immediate casting a fracture at major tertiary-care children's hospital from 2003 2009 reviewed...
In Brief Study Design. Reliability study of the computer-assisted SDSG (Spinal Deformity Group) classification lumbosacral spondylolisthesis. Objective. To assess intra- and interobserver reliability Summary Background Data. The has proposed a new spondylolisthesis based on slip grade, pelvic incidence (PI), sacro-pelvic spinal balance. Three types low-grade are described: low PI (type 1), normal 2), high 3). High-grade defined as type 4 (balanced sacro-pelvis), 5 (retroverted sacro-pelvis...
We performed a retrospective analysis of 212 patients (299 hips) with slipped capital femoral epiphysis (SCFE) over 9-year period to assess the incidence osteonecrosis head. Risk factors for occurrence and influence treatment on development were determined. Osteonecrosis occurred in 4 hips unstable SCFE (4/27) did not occur stable (0/272). The proportion which developed was significantly higher among (4/27 vs. 0/272, p < 0.0001). Among those an hip, younger age at presentation predictor...
The incidence of concomitant, particularly noncontiguous, spine injuries in the pediatric population has not been well described. There is a balance between limiting radiation exposure and missing concomitant injuries; understanding this risk important. We hypothesize that rate spinal children similar to adults.The trauma registry center was queried for all patients who sustained over 10-year period. Patient demographics, presence other injuries, treatment, location nature injury, as...
Reduction of severe spondylolisthesis is controversial. Publications have emphasized the techniques reduction and associated complications, but there little knowledge about effect on sagittal balance spine pelvis in postoperative patient. This study evaluated surgical instrumented fusion pelvic anatomy spinopelvic balance. Methods: a retrospective 26 adolescents (mean age, 13.1 ± 3.3 years) who had partial posterior L4 to sacrum treat high-grade spondylolisthesis. All patients radiographs...
This study aims to critically analyze the major and minor complications that may be associated with plate fixation of pediatric diaphyseal femur fractures.The medical records skeletally immature patients (6-15 years age) who underwent a fracture at tertiary-care level-1 trauma center between 1/2003 12/2010 were reviewed. Demographic clinical information regarding mechanism injury, type, surgical technique recorded. Radiographic evaluation bony healing, hardware position, deformity was...
