后路椎间盘镜下多节段有限减压治疗腰椎管狭窄症18例疗效分析

摘要

Objective:To observe the clinical effect of multi-level limited decompression with microendoscopic disectomy through posterior approach on lumbar spinal stenosis. Methods: Eighteen patients with lumbar spinal stenosis were managed by multi-level limited decompression with microendoscopic disectomy. The preoperative Oswestry disability index (ODI) and visual analogue scale (VAS) were compared with the postoperative scores, and the clinical effects were reviewed and analyzed. Results:There was significant difference in preoperative ODI and VAS compared with the postoperative scores( P ＜ 0.01 ). The follow-up lasted from 8 to 39 months.The evaluation by Nakai standard revealed that the outcome was excellent in 11 cases, good in 3 cases, fair in 3 cases and poor in 1 case. The rate of good results was 77.78％. Conclusions: Multi-level limited decompression by microendoscopic disectomy through posterior approach has the advantages of fewer traumas, less blood loss and better clinical outcome in treatment of lumbar spinal stenosis.%目的:观察后路椎间盘镜下多节段有限减压治疗腰椎管狭窄症的临床疗效.方法:后路椎间盘镜下多节段有限减压治疗18例腰椎管狭窄症,比较治疗前后Oswestry功能障碍指数(ODI)和视觉模拟评分(VAS)变化,观察手术疗效.结果:治疗后ODI和VAS评分明显低于治疗前(P＜0.01).随访8～39个月,按Nakai评价标准评定为优11例,良3例,可3例,差1例,优良率为77.78%.结论:椎间盘镜下多节段有限减压治疗腰椎管狭窄症创伤小,出血少,术后疗效满意.
