BACKGROUND The lack of a reliable, universally acceptable system for classification of adolescent idiopathic scoliosis has made comparisons between various types of operative treatment an impossible task. Furthermore, long-term outcomes cannot be determined because of the great variations in the description of study groups. METHODS We developed a new(More)
STUDY DESIGN A retrospective study. OBJECTIVE To evaluate the safety of a free hand technique of pedicle screw placement in the thoracic spine at a single institution over a 10-year experience. SUMMARY OF BACKGROUND DATA Thoracic pedicle screw fixation techniques are still controversial for thoracic deformities because of possible complications(More)
Recent advances in spinal instrumentation have brought about a new emphasis on the three-dimensional spinal deformity of scoliosis and especially on the restoration of normal sagittal plane contours. Normal alignment in the coronal and transverse planes is easily defined; however, normal sagittal plane alignment is not so simple. This retrospective study(More)
STUDY DESIGN Retrospective clinical, radiographic, and patient outcome review of surgically treated adolescent idiopathic scoliosis. OBJECTIVES To correlate radiographic and clinical features of shoulder balance and the proximal thoracic curve with patient satisfaction outcomes at a minimum 2-year follow-up. SUMMARY OF BACKGROUND DATA Traditionally,(More)
STUDY DESIGN A radiographic evaluation of 100 adult volunteers over age 40 and without a history of significant spinal abnormality was done to determine indices of sagittal spinal alignment. OBJECTIVES To determine the sagittal contours of the spine in a population of adults older than previously reported in the literature and to correlate age and overall(More)
STUDY DESIGN Retrospective review of a prospectively accrued patient cohort. OBJECTIVE The ability to treat severe pediatric spinal deformity through an all-posterior vertebral column resection (VCR) has obviated the need for a circumferential approach in both primary and revision settings. We examined indications, correction rates, and complications of(More)
STUDY DESIGN This study is a retrospective review of 752 patients with adult spinal deformity enrolled in a multicenter prospective database in 2002 and 2003. Patients with positive sagittal balance (N = 352) were further evaluated regarding radiographic parameters and health status measures, including the Scoliosis Research Society patient questionnaire,(More)
BACKGROUND Surgical site infections are not uncommon following spinal operations, and they can be associated with serious morbidity, mortality, and increased resource utilization. The accurate identification of risk factors is essential to develop strategies to prevent these potentially devastating infections. We conducted a case-control study to determine(More)
STUDY DESIGN A retrospective matched cohort study. OBJECTIVE To comprehensively compare the 2-year postoperative results of posterior correction and fusion with segmental pedicle screw instrumentation versus with hybrid (proximal hooks and distal pedicle screws) constructs in adolescent idiopathic scoliosis (AIS) treated at a single institution. SUMMARY(More)
STUDY DESIGN Radiographic analysis, outcomes analysis (pain scale, Oswestry, SRS-24), and accumulation of complications. Outcomes and complications collected prospectively. Radiographic analysis performed retrospectively. OBJECTIVES To assess the benefits and stress complications of pedicle subtraction osteotomies for patients with fixed sagittal(More)
