A retrospective, multicenter study was undertaken to evaluate the early postoperative failure rate of long segment anterior cervical fusion and plating to stabilize the cervical spine after a two- or three-level corpectomy for degenerative, traumatic, and neoplastic diseases of the cervical spine. Patient demographic factors as well as technical factors(More)
A prospective randomized study was designed to examine differences in the primary fusion rate between two surgically treated groups of patients with spondylolisthesis. Twenty-seven patients underwent L5 laminectomy (Gill procedure) and L5 nerve root decompression. Fourteen patients (group I) underwent in-situ posterolateral fusion, thirteen patients (group(More)
STUDY DESIGN  Randomized controlled animal trial. OBJECTIVES  To analyze the early and late phase effects of platelet-rich plasma (PRP) injection into and around the damaged intervertebral disc using an animal model, and to evaluate the needle puncture technique in creating a degenerative disc model. METHODS  The L4-L5 intervertebral disc of 18 adult(More)
Operative management of a thoracolumbar burst fracture varies according to many factors. Fracture morphology, neurologic status, and surgeon preference play major roles in deciding upon anterior, posterior, or combined approaches. Optimizing neural decompression while providing stable internal fixation over the least number of spinal segments is the goal.(More)
STUDY DESIGN Multicenter, prospective equivalency trial with each patient serving as his/her own control. OBJECTIVES To compare the effectiveness of a Grafton DBM gel composite with iliac crest autograft in posterolateral spine fusion. SUMMARY OF BACKGROUND DATA While autograft remains the preferred graft material to facilitate spine fusion, the supply(More)
BACKGROUND In the last several years, the lateral transpsoas approach to the thoracic and lumbar spine, also known as extreme lateral interbody fusion (XLIF) or direct lateral interbody fusion (DLIF), has become an increasingly common method to achieve fusion. Several recent large series describe several advantages to this approach, including less tissue(More)
Decades of research have explored factors that can influence green behavior. However, much less is known about how technology in general, and social technologies in particular can motivate people to participate in green activities. In this paper we describe the goals, design and evaluation of StepGreen.org, a site intended to promote energy-saving(More)
A retrospective study of all surgically treated patients with pyogenic vertebral osteomyelitis grafted with autogenous bone for stability from 1980 to 1985 at the University of Miami and from 1985 to 1987 at Portsmouth Naval Hospital was performed. Eradication of infection occurred in all patients. Infection resolution occurred equally well in cases caused(More)
OBJECTIVE The optimal treatment of "unstable" thoracolumbar injuries remains controversial. Studies have shown the advantages of direct anterior decompression of thoracolumbar injuries along with supplemental posterior instrumentation as a combined or staged procedure. Others have also shown success in decompression as a single-stage anterior procedure,(More)
