摘　　要：目的探讨充分减压、椎弓根螺钉内固定及360°植骨融合术治疗多节段腰椎管狭窄症的疗效。方法采用椎弓根螺钉内固定术及360°植骨融合术治疗34例多节段腰椎管狭窄症患者。结果随访10～23个月，平均14个月。JOA计算手术改善率为75％-91％（平均87％），X线复查34例全部达到骨性融合。结论椎弓根螺钉内固定为腰椎管狭窄症的彻底减压提供可靠的技术支持，360°植骨融合术确保了术后腰椎节段的稳定，两者结合为治疗多节段腰椎管狭窄症提供一种较好的方法。Objective To evaluate the clinical efficacy of the muhisegment lumbar spinal stenosis by sufficient spinal canal decompression and pediele screw fixation and 360 degree fusion with bone graft. Methods The clinical data of 34 patients with multisegmental lumbar spinal stenosis treated with pediele screw fixation and 360 degree fusion with bone graft were summarized. Results The mean follow-up time was 14 months （ ranging from 10 - 23 months）. The rate of the improved JOA seore（RIS） was 75% -91% （an average af87% ）. The bony arthrodesis rate was 100% in X-ray films. Conclusions The technique of pediele screw fixation provides reliable support for thorough decompression of lumbar spinal stenosis. 360 degree fusion with bone graft ensures the postoperative stabilization of lumbar segments. The way of pediele screw fixation and 360 degree fusion with bone graft is a better method to muhisegmental lumbar spinal stenosis.
