STUDY DESIGN Randomized prospective trial. OBJECTIVE To compare the efficacy of intravenous analgesia with single and dual continuous epidural analgesia (CEA) in patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal fusion and instrumentation (PSIF). SUMMARY OF BACKGROUND DATA Pain management after posterior spinal fusion (PSF)(More)
OBJECTIVES This study is designed to test the comparative strength of lateral-only locked plating to medial and lateral nonlocked plating in a cadaveric model of a bicondylar proximal tibial plateau fracture. METHODS Ten matched pairs of human cadaveric proximal tibia specimens were used for biomechanical testing. Cyclic loading using a materials testing(More)
Lower Extremity Assessment Project (LEAP) study set out to answer many of the questions surrounding the decision of whether to amputate or salvage limbs in the setting of severe lower extremity trauma. A National Institutes of Health-funded, multicenter, prospective observational study, the LEAP study represented a milestone in orthopedic trauma research,(More)
BACKGROUND Extension of a vertebral exostosis into the spinal canal is rare, but many isolated cases have been reported in the literature. Three existing patients with multiple hereditary exostoses at our institution had development of neurologic findings and were found to have exostoses in the spinal canal. These findings led us to perform magnetic(More)
OBJECTIVES Bicondylar tibial plateau fractures featuring extensive articular involvement have a record of mixed clinical results. Recent discussion has focused on the significance of a posteromedial articular fragment in bicondylar injuries. This fragment has often gone unrecognized or has not been addressed. The posteromedial fragment is defined as any(More)
Torsional deformities of the femur and/or tibia often go unrecognized in adolescents and adults who present with anterior knee pain, and patellar maltracking or instability. While open and arthroscopic surgical techniques have evolved to address these problems, unrecognized torsion may compromise the outcomes of these procedures. We collected a group of 16(More)
BACKGROUND Children with rickets are prone to having deformities of the lower extremities that are bilateral and often symmetrical. Although initially attributed to pathological or "sick" physes, the deformities are eventually seen in the metaphyses and diaphyses of the long bones; if left untreated, they may result in bone pain and stress fractures. The(More)
BACKGROUND Fixed knee flexion deformity (FKFD) is an insidious problem that may complicate the management of patients with neuromuscular compromise due to cerebral palsy, spina bifida, arthrogryposis, and other conditions. The energy costs associated with crouch gait may become prohibitive and, with the inexorable progression of fixed knee flexion,(More)
BACKGROUND For children undergoing treatment of early onset scoliosis (EOS) using spine-based distraction, recently published research would suggest that total spine length (T1-S1) achieved after the initial lengthening procedure decreases with each subsequent lengthening. Our purpose was to evaluate the effect of rib-based distraction on spine growth in(More)
BACKGROUND Medial humeral epicondyle fracture displacement in children is difficult to quantify, as current methods suffer from significant intraobserver and interobserver variability. The aim of this study was to create a systematic approach to determine medial epicondyle fracture displacement based upon easily identifiable radiographic landmarks of the(More)
