Efficacy of unilateral laminectomy for bilateral decompression in lumbar spinal stenosis.
OBJECTIVE We have conducted a prospective study to evaluate the results and effectiveness of bilateral decompression via a unilateral laminectomy in 50 patients with 98 levels of degenerative lumbar spinal stenosis without instability. METHODS Clinical outcomes were assessed using the Visual Analog Scale, Oswestry Disability Index, Short Form-36, and subjective Satisfaction Measurement. RES...
متن کاملOutcome after Surgery of Lumbar Spinal Stenosis: A Randomized Comparison of Bilateral Laminotomy, Trumpet Laminectomy, and Conventional Laminectomy
BACKGROUND Laminectomy is the traditional operating method for the decompression of spinal canal stenosis. New partial decompression processes have been suggested in the treatment of lumbar stenosis. The benefit of a micro surgical approach is the chance of an extensive bilateral decompression of the spinal canal or foramen at one or numerous levels, through a minimal para-spinal muscular separ...
متن کاملComparison of Spinous Process-Splitting Laminectomy versus Conventional Laminectomy for Lumbar Spinal Stenosis
STUDY DESIGN Seventy-five patients who had been treated for lumbar spinal stenosis (LSS) were reviewed retrospectively. PURPOSE Invasion into the paravertebral muscle can cause major problems after laminectomy for LSS. To address these problems, we performed spinous process-splitting laminectomy. We present a comparative study of decompression of LSS using 2 approaches. OVERVIEW OF LITERATU...
متن کاملThe cost effectiveness of dynamic and static interspinous spacer for lumbar spinal stenosis compared with laminectomy
Background: The present study aims to evaluate the cost-effectiveness of Dynamic Interspinous Spacer (Coflex®) and Static Spacer (X-STOP ®) compared to Laminectomy (LAMI) in patients with lumbar spinal stenosis. Methods: A decision-analysis model was developed to estimate the cost-effectiveness. The effectiveness parameters were obtained from a systematic literature review in ...
