手术治疗腰椎管狭窄合并椎间盘突出症的疗效分析

目的:分析手术治疗腰椎管狭窄合并椎间盘突出症疗效。方法:回顾性分析156例腰椎管狭窄合并椎间盘突出症患者术前、手术及术后随访等临床资料。结果:156例腰椎管狭窄合并椎间盘突出症患者中全椎板切除103例,半椎板切除38例,开窗术15例,术后疗效优良率全椎板切除95％,半椎板切除90.1％,开窗术86.2％,腰背肌锻炼好的患者无一例发生脊柱不稳。结论:全椎板切除治疗腰椎管狭窄合并椎间盘突出症疗效优于半椎板切除术和开窗术,三种方法对脊柱稳定性影响没有显著差异。

Operative Therapeutic Analysis of Lumbar Spinal Canal Stenosis and Concomitant Prolapse ofLumbar intervertebral Disc

Objective: To analyse operative therapeutic efficiency of lumbar spinal canal stenosis and concomitant prolapse of lumbar intervertebral disc with different surgical methods. Methods: The clinical data of 156 cases with lumbar spinal canal stenosis and concomitant prolapse of lumbar intervertebral disc were retrospectively studied. Results: 103 cases were treated by total laminectomy 38 cases by hemilaminectomy, 15 cases by laminal fenestration in 156 cases with lumbar spinal canal stenosis and concomitant prolapse of lumbar intervertebral disc Excellent/good rate of total laminectomy, hemilaminectomy and laminal fenestration's therapeutic efficiency was separately 95%, 90.1%, 86.2%. There wasn't case with a complicated spinal stability in case with all good training lumbodorsal muscles. Coclusion: Total laminectomy is beter than hemilaminectomy and laminal fenestration in surgical treatment of lumbar spinal canal stenosis and concomitant prolapse of lumbar intervertebral disc. There is no significant difference among the three different surgical methods for spinal stability.
