后路椎弓根螺钉内固定联合椎间植骨融合治疗Ⅱ、Ⅲ度腰椎滑脱临床探究[摘要] 目的 探讨后路椎弓根螺钉内固定联合椎间植骨融合治疗Ⅱ、Ⅲ度腰椎滑脱临床疗效。 方法 回顾性分析我院2009年1月～2011年1月收治入院的30例腰椎滑脱症患者临床资料，所有病例均为Ⅱ、Ⅲ度腰椎滑脱。患者均采用后路椎弓根螺钉内固定联合椎间植骨融合治疗，观察手术前后临床症状及滑脱恢复情况、术后复位、疗效评价、材料生物相容性、术后椎间隙高度及BFS评分。 结果 30例患者术前均为Ⅱ、Ⅲ度腰椎滑脱，其中，19例行椎管、神经根管减压、复位固定、植骨融合治疗，11例只行复位固定、植骨融合治疗。获得随访30例，均超过12个月。30例椎间植骨全部融合，融合率为100%。BFS评分优良率达90.0%。 结论 后路椎弓根螺钉内固定联合椎间植骨融合治疗Ⅱ、Ⅲ度腰椎滑脱，操作简便、固定可靠，是临床治疗中的一种值得推广的方法。 [关键词] 腰椎滑脱症；椎体间加压融合；生物力学；椎弓根螺钉；内固定 [中图分类号] R681.5 [文献标识码] A [文章编号] 1673-7210（2012）07（b）-0047-03 The clinical research of posterior transpedicular screw fixation combined with intervertebral bone grafting fusion in the treatment of Ⅱdegree and Ⅲdegree lumbar spondylolisthesis NING Kai CHENG Lixin WANG Zhigang LI Kun JI Zhe The People’s Hospital of Xinjiang Uygur Autonomous Region, Urumchi 830001, China [Abstract] Objective To explore the curative effect of posterior transpedicular screw fixation combined with intervertebral bone grafting fusion in the treatment of Ⅱdegree and Ⅲdegree lumbar spondylolisthesis. Methods The clinical data of 30 patients with lumbar spondylolisthesis from January 2009 to January 2011 in our hospital were analyzed retrospectively. All cases were suffered with Ⅱdegree or Ⅲdegree lumbar spondylolisthesis. All patients were adopted posterior transpedicular screw fixation combined with intervertebral bone grafting fusion treatment. The clinical symptoms, slippage recovery condition before and after operation, postoperative restoration, therapeutic effect evaluation, material biocompatibility, postoperative intervertebral height and BFS score were observed. Results 30 patients all suffered with Ⅱdegree or Ⅲdegree lumbar spondylolisthesis before surgery, among whom 19 cases were treated with canalis vertebralis and nerve root canal decompression, reduction and fixation and bone graft fusion. Other 11 cases were treated without decompression. All of 30 cases were followed up more than 12 months, the intervertebral fusion were all fused, the fusion r
