A review: Reduced reoperation rate for multilevel lumbar laminectomies with noninstrumented versus instrumented fusions
BACKGROUND The reoperation rate, including for adjacent segment disease (ASD), is lower following multilevel lumbar laminectomy with noninstrumented versus instrumented fusions. METHODS This study reviews selected literature focusing on the reoperation rate, including for ASD, following multilevel laminectomies with noninstrumented versus instrumented fusions. Several prior studies document a...
متن کاملRecombinant human Bone Morphogenetic Protein-2 (rhBMP-2) in posterolateral lumbar spine fusion: complications in the elderly
STUDY DESIGN Retrospective cohort study of 1430 patients undergoing lumbar spinal fusion from 2002 - 2009. OBJECTIVE The goal of this study was to compare and evaluate the number of complications requiring reoperation in elderly versus younger patients. SUMMARY OF BACKGROUND DATA rhBMP-2 has been utilized off label for instrumented lumbar posterolateral fusions for many years. Many series h...
متن کاملHigh lumbar noninstrumented fusion rates using lamina autograft and Nanoss/bone marrow aspirate
BACKGROUND Patients with marked osteoporosis and/or obesity/morbid obesity and severe multilevel lumbar stenosis and other pathology often undergo multilevel laminectomies with non instrumented posterolateral fusions (PLF). The other pathology may include combinations of degenerative spondylolisthesis/lysis, foraminal/far lateral discs, and/or synovial cysts requiring more extensive facet resec...
متن کاملA prospective, randomized, controlled, multicenter study of osteogenic protein-1 in instrumented posterolateral fusions: report on safety and feasibility.
STUDY DESIGN A prospective, randomized, controlled, multicenter clinical study. OBJECTIVE To evaluate the safety and feasibility of osteogenic protein (OP)-1 in 1-level lumbar spine instrumented posterolateral fusions. SUMMARY OF BACKGROUND DATA Instrumented posterolateral fusion with the use of autograft is a commonly performed procedure for a variety of spinal disorders. However, harvesti...
متن کاملUse of Nanocrystalline Hydroxyapatite With Autologous BMA and Local Bone in the Lumbar Spine
STUDY DESIGN A retrospective, multicenter, medical record review and independent analysis of computed tomographic scans was performed in 46 patients to determine radiographic arthrodesis rates after 1-segment, 2-segment, or 3-segment instrumented posterolateral fusions (PLF) using autograft, bone marrow aspirate (BMA), and a nanocrystalline hydroxyapatite bone void filler (nHA). OBJECTIVE To ...
