Analysis of Factors Contributing to Postoperative Spinal Instability after Lumbar Decompression for Spinal Stenosis
OBJECTIVE Decompressive laminectomy is one of the most commonly used surgical methods for the treatment of spinal stenosis. We retrospectively examined the risk factors that induce spinal instability, including slippage (spondylolisthesis) and/or segmental angulation after decompressive laminectomy on the lumbar spine. METHODS From January 1, 2006 to June 30, 2010, 94 consecutive patients und...
متن کاملPercutaneous endoscopic transforaminal lumbar spinal canal decompression for lumbar spinal stenosis
This study aimed to evaluate the safety and curative effect of percutaneous endoscopic transforaminal lumbar spinal canal decompression in the treatment of lumbar spinal stenosis.This retrospective study recruited 64 patients with lumbar spinal stenosis who underwent percutaneous endoscopic lumbar spinal canal decompression via surgical approach of posterolateral intervertebral foramen. The pos...
متن کاملEffects of Age and Spinal Level on the Dimensions of the Lumbar Spinal Canal Measured in vivo
INTRODUCTION Accurate morphometric characterization of the lumbar spinal canal is important in understanding low back disorders such as lumbar spinal stenosis. Current conventional methods measuring the AP diameter of the canal, a common parameter for defining the canal, use practical and clinically available methods where patient CT scans are analyzed in 2D. This method, however, does not take...
متن کاملPostoperative lumbar canal stenosis due to anterior spinal fusion.
Three cases of postoperative lumbar spinal canal stenosis due to anterior spinal fusion were reported. In these cases stenosis occurred at the adjacent intervertebral disc level of the fused segment a considerable time after anterior spinal fusion performed for spondvlolisthesis. At the stenotic level of the lumbar spinal canal, hypertrophy of the lamina, body spur formation in the articular pr...
متن کاملMicro Lumbar Decompression for Lumbar Spinal Stenosis
Spinal stenosis was described, for the first time, as one of the causes of neural compression by Bailey and Casamajor (1) in 1911. Later, in 1954, it was described by Verbiest (2) as the typical clinical presentation of bilateral neurogenic claudication, which is provoked by prolonged standing and lower back extension and relieved by sitting and flexing the lumbar spine. Degenerative lumbar spi...
