BACKGROUND Modified Dunn osteotomy has gained popularity over the past decade in the treatment of moderate to severe adolescent slipped capital femoral epiphysis. The purpose of this study was to retrospectively evaluate a consecutive series of adolescent slipped capital femoral epiphysis patients treated with the modified Dunn procedure at a single(More)
STUDY DESIGN Retrospective chart review and radiographic analysis. OBJECTIVE To determine if differences exist in the sagittal alignment of adolescent idiopathic scoliosis (AIS) patients with thoracic versus thoracolumbar curve patterns. SUMMARY OF BACKGROUND DATA Relative anterior overgrowth has been suggested as the possible pathomechanism behind(More)
STUDY DESIGN A retrospective review of surgical outcomes in adolescents with idiopathic scoliosis. OBJECTIVE To determine if an association exists between body mass and surgical outcomes in adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Obesity has reached epidemic proportions globally. In adults, obesity increases the likelihood of(More)
BACKGROUND Spinal growth modulation by tethering the anterolateral aspect of the spine, as previously demonstrated in a nonscoliotic calf model, may be a viable fusionless treatment method for idiopathic scoliosis. The purpose of the present study was to evaluate the radiographic, histologic, and biomechanical results after six and twelve months of spinal(More)
STUDY DESIGN A multicenter study of changes in Scoliosis Research Society (SRS) outcome measures after surgical treatment of adolescent idiopathic scoliosis (AIS). OBJECTIVE To evaluate changes in patient determined outcome measures between 2 and 5 years after AIS surgery. SUMMARY OF BACKGROUND DATA Current surgical procedures have been shown to improve(More)
BACKGROUND The surgical outcomes in patients with scoliosis at two years following anterior thoracoscopic spinal instrumentation and fusion have been reported. The purpose of this study was to evaluate the results at five years. METHODS A consecutive series of forty-one patients with major thoracic scoliosis treated with anterior thoracoscopic spinal(More)
STUDY DESIGN Bench-top and retrospective analysis to assess vertebral rotation based on the appearance of bilateral pedicle screws in patients with adolescent idiopathic scoliosis (AIS). OBJECTIVE To develop a clinically relevant radiographic grading system for evaluating postoperative thoracic apical vertebral rotation that would correlate with computed(More)
STUDY DESIGN Retrospective review of a series of adolescent idiopathic scoliosis patients. OBJECTIVE To perform a 3-dimensional (3D) analysis of patients with thoracic scoliosis to identify differences in the thoracic sagittal alignment measured from the standard lateral projection as compared to the "true lateral" view. SUMMARY OF BACKGROUND DATA It(More)
STUDY DESIGN In vitro biomechanical investigation. OBJECTIVE To evaluate differences in biomechanical stability of vertebral compression fractures repaired using balloon kyphoplasty versus a titanium mesh implant. SUMMARY OF BACKGROUND DATA Vertebral compression fractures may be stabilized using an expandable balloon followed by cement injection. There(More)
