STUDY DESIGN Prospective, sequential enrollment. OBJECTIVE We report the development and testing of the Spinal Appearance Questionnaire (SAQ) for reliability, validity, and responsiveness in patients with idiopathic scoliosis. SUMMARY OF BACKGROUND DATA The SAQ was designed to measure patients' and their parents' perception of their spinal deformity's(More)
STUDY DESIGN Clinical study correlating preoperative pulmonary function tests (PFTs) to radiographic measures of thoracic deformity severity in adolescent idiopathic scoliosis (AIS) patients. OBJECTIVE To determine (1) the incidence of clinically relevant (<65% predicted value) pulmonary impairment in AIS patients; (2) if patients with more severe(More)
BACKGROUND Long-term studies have indicated good outcomes for most patients with Legg-Calvé-Perthes disease. However, clinical experience suggests that less favorable outcomes are common. We sought to prospectively document pain and function in a cohort of adults who had previously been treated nonoperatively for Legg-Calvé-Perthes disease. METHODS(More)
STUDY DESIGN Cross sectional. OBJECTIVE This study presents the factor analysis of the Spinal Appearance Questionnaire (SAQ) and its psychometric properties. SUMMARY OF BACKGROUND DATA Although the SAQ has been administered to a large sample of patients with adolescent idiopathic scoliosis (AIS) treated surgically, its psychometric properties have not(More)
BACKGROUND The Bernese (Ganz) periacetabular osteotomy is an effective surgical procedure to reorient the acetabulum, allowing restoration of anatomic femoral head coverage and medial translation of the hip in adults with hip dysplasia. However, it is a challenging surgical procedure, and we know of no study that has specifically analyzed the complications(More)
BACKGROUND The Ganz (Bernese) periacetabular osteotomy was first described for the treatment of adult patients with hip dysplasia; however, it has also been used for adolescent patients. Its effectiveness in improving patients in the short term has not been fully established and no studies, to our knowledge, have analyzed gait and functional outcome in(More)
STUDY DESIGN Retrospective multicenter review. OBJECTIVE Determine the definition, indications, results, and outcomes, focusing on complications of vertebral column resection (VCR) for severe pediatric spinal deformity. SUMMARY OF BACKGROUND DATA The strict definition of the VCR procedure, indications, results, outcomes, and the numerous, potentially(More)
STUDY DESIGN A multicenter retrospective analysis. OBJECTIVE To evaluate outcomes of closed-suction wound drainage after posterior spinal fusion with instrumentation for adolescent idiopathic scoliosis and to identify surgeon patterns of drain use in this cohort. SUMMARY OF BACKGROUND DATA There is little evidence on the use of drains in spinal surgery,(More)
BACKGROUND Questions remain as to the effect of pedicle screws on spinal canal development in young children. The purpose of this study was to determine the effects of unilateral placement of dual screws across the neurocentral synchondrosis on spinal canal development as assessed with histological analysis and measurement of the canal dimensions in an(More)
STUDY DESIGN Longitudinal cohort. OBJECTIVE To determine the minimum clinically important difference (MCID) of the Scoliosis Research Society (SRS)-22 Appearance, Activity, and Pain domains in patients with adolescent idiopathic scoliosis undergoing surgical correction of their spinal deformity. SUMMARY OF BACKGROUND DATA The MCID, a threshold of(More)
