有限椎板切除术对腰椎管狭窄及中央型腰椎间盘突出的治疗作用

Treatment for lumbar spinal stenosis and central disc herniation with limited laminectomy

目的:评价有限椎板切除术对腰椎管狭窄症以及中央型腰椎间盘突出症的治疗效果。方法:对我科2000年1月至2003年12月期间随访的采用有限椎板切除术治疗的137例腰椎管狭窄症和(或)中央型腰椎间盘突出症患者的术后症状改善情况进行调查评价。结果:本组病例总数137例,其中男78例,女59例,平均年龄45.6岁,随访时间最长15个月,最短1个月,平均6个月。术后腰痛改善总有效率83%,腿痛改善总有效率96%,仅1例病人由于椎间盘复发行再手术椎间融合治疗。结论:有限椎板切除术能够有效地治疗腰椎管狭窄症以及中央型腰椎间盘突出症,而且能够更好地保存脊椎稳定结构而大大降低并发症的发病率。目的:评价有限椎板切除术对腰椎管狭窄症以及中央型腰椎间盘突出症的治疗效果。方法:对我科2000年1月至2003年12月期间随访的采用有限椎板切除术治疗的137例腰椎管狭窄症和(或)中央型腰椎间盘突出症患者的术后症状改善情况进行调查评价。结果:本组病例总数137例,其中男78例,女59例,平均年龄45.6岁,随访时间最长15个月,最短1个月,平均6个月。术后腰痛改善总有效率83%,腿痛改善总有效率96%,仅1例病人由于椎间盘复发行再手术椎间融合治疗。结论:有限椎板切除术能够有效地治疗腰椎管狭窄症以及中央型腰椎间盘突出症,而且能够更好地保存脊?

Objective To investigate the effect of limited laminectomy on treatment for lumbar spinal stenosis and central disc herniation. Methods One hundred and thirty seven patients with lumbar spinal stenosis or central disc herniation surgically treated with limited laminectomy were retrospectively reviewed from January 2000 to November 2003. Postoperative follow up were made by symptomatology to evaluate effect of limited laminectomy. Results Overall improvement postoperatively was noted in 83%of back pain or 96%of leg pain in patients with lumbar spinal stenosis and/or central disc herniation. Only one patient had undergone subsequent fusion of the lumbar spine after laminectomy. Conclusion The limited laminectomy could better preserve the spinal natural architecture and may contribute to improve postoperative stability. The limited laminectomy is a good alternative to total laminectomy.
