摘　　要：目的探讨椎弓根内固定加椎体间植骨融合治疗下腰椎不稳症的手术方法及临床疗效。方法 2005年3月～2011年8月退行性下腰椎不稳症42例,行后路开窗减压椎弓根固定,植骨方法采用单纯椎体间植骨。术后随访观察椎体间植骨融合情况及临床效果,根据腰椎滑脱手术治疗疗效评定标准及植骨融合评定标准进行评价。结果 42例病例均获得随访,随访6～54个月,所有患者均达到骨性融合,无内固定物松动或断裂,疗效评定,痊愈29例,好转10例,改善3例。优良率92.8%。结论退行性腰椎不稳症患者采取后路椎弓根内固定结合椎间植骨的方法治疗,融合率高,临床疗效满意。Objective To investigate the therapeutic effect of the transpedicle fixation combined with interbody fusion in in lumbar disc herniation and spinal instability. Methods From Mar 2005 to Aug 2011,42 cases of degenerative lumbar spinal instability were treated with canal decompression and transpedicle screw fixation combined with interbody fusion. Follow-up observations included the outcomes of interbody fusion and clinical effect. The evaluation was based on assessing standards about interbody fusion and clinical effect. Results Forty-two patients were followed up for 6 months to 54 months postoperativly. All of them are fused, no internal fixation loosening or failure, 29 cases are cure, I0 cases are mend, 3 cases are improved,the excellent and good rate was 92.8%. Conclusions The surgical technique of canal decompression and transpedicle fixation combined with interbody fusion is an effctive method for treatment of degenerative lumbar spinal instability.
