Surgical management of lumbar stenosis: decompression and indications for fusion.
Review of the clinical, neuroradiological, and surgical management of lumbar spinal stenosis reveals that 90 to 95% of congenital or acquired variants may be adequately managed by means of decompression without fusion. These decompressive procedures often simultaneously treat disc herniations, limbus fractures, degenerative spondylolisthesis, rare selected cases of spondylolisthesis accompanied by lysis in older patients, and degenerative scoliosis. Fusion should be reserved for the approximately 5 to 10% of patients in whom there is clinical evidence of instability prior to surgery or for the few who develop slippage following laminectomy and facetectomy.
