BACKGROUND To our knowledge, a prospective, randomized study comparing operative and nonoperative treatment of a thoracolumbar burst fracture in patients without a neurological deficit has never been performed. Our hypothesis was that operative treatment would lead to superior long-term clinical outcomes. METHODS From 1994 to 1998, forty-seven consecutive(More)
STUDY DESIGN This study prospectively evaluated the health related quality of life (HRQOL) of 73 adults presenting with scoliosis at a single institution, as related to their spinal (C7 plumbline) and global (gravity line) balance. OBJECTIVE To assess the influence of sagittal and coronal balance on HRQOL in adult scoliosis. SUMMARY OF BACKGROUND DATA(More)
The efficacy of trigger-point injection therapy in treatment of low-back strain was evaluated in a prospective, randomized, double-blind study. The patient population consisted of 63 individuals with low-back strain. Patients with this diagnosis had nonradiating low-back pain, normal neurologic examination, absence of tension signs, and lumbosacral(More)
Eighteen neurologically intact patients with burst fractures at the thoracolumbar junction were treated with early ambulation in a total contact orthosis. No attempt was made to reduce the associated deformity. Selection criteria excluded patients with posterior column disruption. Hospital stay averaged 10 days. Follow-up averaged 19 months. Mean kyphosis(More)
STUDY DESIGN A retrospective review involved 135 patients undergoing anterior interbody fusion using four different approaches: transperitoneal video-assisted surgery with insufflation, retroperitoneal endoscopic video-assisted surgery, minilaparotomy retroperitoneal surgery, and traditional oblique muscle-splinting retroperitoneal surgery. OBJECTIVE To(More)
STUDY DESIGN Prospective clinical series with comparison to retrospectively collected data. OBJECTIVE To compare direct measures of postoperative hematoma volume against a new measure of hematoma effect on the thecal sac: the critical ratio. SUMMARY OF BACKGROUND DATA Asymptomatic epidural hematoma is common after lumbar surgery. Symptomatic patients(More)
OBJECTIVE The objective of this study is to evaluate the effectiveness of a specific methodology for plain radiographic assessment of lumbar pedicle screw position. PURPOSE To evaluate the effectiveness of using orthogonal plain radiographs and a systematic method of interpretation, developed by the senior author, in assessing the placement of lumbar and(More)
STUDY DESIGN Retrospective clinical cohort study. OBJECTIVE To determine the efficacy of posterior lateral mass screw/rod fixation and fusion for the treatment of symptomatic pseudarthrosis of anterior cervical fusion. SUMMARY OF BACKGROUND DATA Both anterior revision and posterior repair of cervical pseudarthrosis have been reported. To date, there is(More)
BACKGROUND CONTEXT Several conservative therapies have been shown to be beneficial in the treatment of chronic low back pain (CLBP), including different forms of exercise and spinal manipulative therapy (SMT). The efficacy of less time-consuming and less costly self-care interventions, for example, home exercise, remains inconclusive in CLBP populations. (More)
STUDY DESIGN Retrospective comparative study of 2 approaches to multilevel fusion for cervical spondylosis in consecutive patients at a single institution. OBJECTIVE To provide justification for a concomitant posterior approach in multilevel cervical fusion for spondylosis by demonstrating decreased pseudarthrosis and reoperation rates. SUMMARY OF(More)
