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 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)
BACKGROUND Lateral condyle humerus fracture nonunion after surgical fixation has been reported to be <1%. The purpose of this study was to evaluate the rate and risk factors for delayed healing of pediatric lateral condyle fractures after surgical fixation. METHODS Retrospective study of all operatively treated lateral condyle fractures at a single(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)
STUDY DESIGN Retrospective review of a multicenter prospectively collected series of adolescent idiopathic scoliosis (AIS) patients. OBJECTIVE To compare uninstrumented compensatory curve spontaneous derotation of the rib hump and lumbar prominence after selective lumbar or thoracic fusions in AIS. SUMMARY OF BACKGROUND DATA Coronal correction of the(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)
The purpose of this study was to evaluate whether deeper-than-recommended insertion of a suture anchor within the rotator cuff footprint of human cadaveric humeri affects fixation characteristics. Metallic 5-mm screw-in anchors loaded with a single No. 2 suture were placed in the infraspinatus footprint of 8 human cadaveric humeri at standard and deep(More)
