【摘要】 目的探讨腰椎管环形减压治疗腰椎管狭窄症的方法及疗效。方法自病变间隙切除棘间韧带，咬除部分上、下棘突和椎板（１／４～１／３），切除黄韧带，两侧小关节突内缘有限切除（＜１／３）。前方凿除骨性凸起及摘除突出髓核。结果２０例经１年～１年５个月随访，疗效均为优。结论腰椎管环形减压既可对腰椎管狭窄进行减压，又可减少对腰椎稳定性的影响。更多还原

【Abstract】 Objective To discuss the operative method and the effect of lumbar canal circular decompression in the treatment of lumbar vertebral canal stenosis. Methods The interspinous ligament, partial vertebral process and vertebral lamina(1/4￣1/3)and ligament flavum were resected from the space of the lesion first, and then the localized resection of the inner verge of the little joint process was made, the osseous bulge and the bulgy core were digged out finally from the front of the lesion.
