STUDY DESIGN Prospective multicenter study evaluating operative (OP) versus nonoperative (NONOP) treatment for adult spinal deformity (ASD). OBJECTIVE Evaluate correlations between spinopelvic parameters and health-related quality of life (HRQOL) scores in patients with ASD. SUMMARY OF BACKGROUND DATA Sagittal spinal deformity is commonly defined by an(More)
STUDY DESIGN Three-dimensional computed tomography (CT) radiographic analysis. OBJECTIVE To describe the parameters for a trajectory through a sacral starting point as a method of pelvic fixation in spinal deformity and to compare this technique with insertion from the posterior superior iliac spine (PSIS). SUMMARY OF BACKGROUND DATA Long anchors(More)
STUDY DESIGN Retrospective review of a multicenter database of consecutive patients undergoing 3-column osteotomy for treatment of adult spinal deformity (ASD). OBJECTIVE To rigorously develop a T1 pelvic angle (TPA) categorization paradigm and use it to assess the surgical management of patients with ASD. SUMMARY OF BACKGROUND DATA TPA, the angle(More)
In order to identify the risk factors and the incidence of post-operative spinal epidural haematoma, we analysed the records of 14 932 patients undergoing spinal surgery between 1984 and 2002. Of these, 32 (0.2%) required re-operation within one week of the initial procedure and had an International Classification of Diseases (ICD)-9 code for haematoma(More)
BACKGROUND CONTEXT The sacroiliac joint is known to be a possible cause of chronic low back pain, but the diagnosis and treatment of disorders of the sacroiliac joint have been difficult and controversial. PURPOSE To describe the outcome of sacroiliac joint arthrodesis for sacroiliac joint disorders, with the hypothesis that sacroiliac arthrodesis leads(More)
The cauda equina syndrome in ankylosing spondylitis (the CES-AS syndrome) is marked by slow, insidious progression and a high incidence of dural ectasia in the lumbosacral spine. A high index of suspicion for this problem must be maintained when evaluating the patient with ankylosing spondylitis with a history of incontinence and neurologic deficit on(More)
STUDY DESIGN Retrospective case series of surgically treated patients with adult spine deformity (ASD). OBJECTIVE To report the incidence of proximal junctional failure (PJF), characterize PJF and evaluate the outcome of revision surgery for PJF. A modified classification is also proposed. SUMMARY OF BACKGROUND DATA Although recent reports have shown(More)
STUDY DESIGN A prospective study. OBJECTIVE Our purpose was to evaluate prospectively the complications, clinical outcomes, and self-reported quality of life in a relatively homogenous group of adults aged ≥ 40 years undergoing primary surgical treatment for scoliosis. SUMMARY OF BACKGROUND DATA Relatively few reports have examined surgical outcomes in(More)
BACKGROUND Few studies have examined threshold improvements in health-related quality of life (HRQOL) by measuring minimal clinically important differences (MCIDs) in treatment of adult spinal deformity. We hypothesized that patients undergoing operative treatment would be more likely to achieve MCID threshold improvement compared with those receiving(More)
OBJECT Back and leg pain are the primary outcomes of adult spinal deformity (ASD) and predict patients' seeking of surgical management. The authors sought to characterize changes in back and leg pain after operative or nonoperative management of ASD. Outcomes were assessed according to pain severity, type of surgical procedure, Scoliosis Research Society(More)
