BACKGROUND The published two-year results of the pivotal U.S. Food and Drug Administration investigational device exemption trial with the use of the Bryan cervical disc arthroplasty compared with anterior cervical discectomy with fusion for treating single-level degenerative cervical disc disease revealed a significantly superior overall success rate in(More)
BACKGROUND CONTEXT To our knowledge, there is no clinical study analyzing the feasibility and complications of the routine insertion of the lateral mass screw via the posterior arch for C1 fixation in a live surgical setting. PURPOSE To evaluate the feasibility of routine insertion of the lateral mass screw via the posterior arch and related(More)
BACKGROUND The arcuate foramen is an important osseous anomaly of the first cervical vertebra (the atlas) that must be taken into consideration during placement of lateral mass screws into the atlas. METHODS The prevalence of this anomaly in our patient population was determined through a retrospective review of 464 lateral radiographs of the neck. The(More)
STUDY DESIGN A total of 709 skeletally mature atlas specimens were obtained from the Hamann Todd Collection at the Cleveland Museum of Natural History. Using digital caliper, the thickness of the vertebral artery groove was measured to determine the feasibility of potential screw placement. OBJECTIVE To determine the feasibility of screw insertion into(More)
We reviewed the results of acute management of patients who had sustained a dural tear during an operation on the lumbar spine, and we attempted to determine the long-term sequelae of this complication. In the five years from July 1989 to July 1994, 641 consecutive patients had a decompression of the lumbar spine, performed by the senior one of us; of these(More)
BACKGROUND The purpose of the present study was to determine the effectiveness of selective nerve-root injections in obviating the need for an operation in patients with lumbar radicular pain who were otherwise considered to be operative candidates. Although selective nerve-root injections are used widely, we are not aware of any prospective, randomized,(More)
BACKGROUND It has been our experience that ossification occurs adjacent to anterior cervical plates. Our hypothesis was that the closer the plate is to the adjacent disc space, the greater the ossification. METHODS We retrospectively reviewed the lateral radiographs of the cervical spine of 118 patients who had a solid fusion following an anterior(More)
STUDY DESIGN Prospective analysis of preoperative and postoperative radiological data. OBJECTIVE To assess the incidence and extent of laminar closure after Hirabayashi open-door laminoplasty, as determined by multi-detector computed tomography (CT), and to investigate the influence of this phenomenon on spinal cord compression, as shown by magnetic(More)
STUDY DESIGN A cross-sectional retrospective radiologic study. OBJECTIVES To establish concordance rates between interpretations of computed tomography myelography and magnetic resonance imaging in patients with degenerative cervical spine disease. SUMMARY OF BACKGROUND DATA Observed discrepancies in interpretation of computed tomography myelography and(More)
BACKGROUND There has been an increasing number of reports regarding the benefits of vertebroplasty for the treatment of vertebral compression fractures. In this investigation, validated outcome tools were utilized to document the impact of vertebroplasty on pain and function. METHODS Fifty patients were recruited at a tertiary university hospital.(More)
