Thirteen patients who had a burst fracture of the thoracolumbar spine (the twelfth thoracic to the fifth lumbar vertebra) were managed with the use of long rods and a short arthrodesis (the so-called rod-long, fuse-short technique). The patients were followed for an average of seventy-four months (range, thirty-four to 118 months). Six months after the(More)
STUDY DESIGN This is a prospective, randomized study comparing iliac crest bone graft to bone morphogenetic protein (BMP)/compression resistant matrix in instrumented posterolateral fusions for single-level lumbar degenerative disease. A higher recombinant human bone morphogenetic protein (rhBMP)-2 dose and a carrier specific for posterior spine(More)
BACKGROUND The value of lumbar spine arthrodesis in older patients is not well documented. As most of the literature regarding lumbar arthrodesis in older patients has focused on the prevalence of complications, the purpose of this study was to determine the clinical outcomes for older compared with younger patients undergoing lumbar arthrodesis. METHODS(More)
STUDY DESIGN Retrospective review of prospectively collected data, as part of an IRB-approved, FDA-regulated, randomized, nonblinded IDE trial of rhBMP-2 matrix for lumbar spinal fusion. OBJECTIVES The purpose of this study is to examine the influence of smoking on fusion rate and outcome in a large series of patients treated with an rhBMP-2 matrix(More)
