撑开型椎间融合器在腰椎不稳症治疗中的应用

撑开型椎间融合器在腰椎不稳症治疗中的应用【摘要】 目的 探讨撑开型椎间融合器治疗腰椎不稳症的临床疗效。方法 采纳Oswestry 功能障碍指数(Oswestry Disability Index, ODI)对患者术前、术后症状进行评定, 测量患者术前、术后椎间隙前凸角度及动力位片椎体间角度活动域，观察融合率和并发症。结果 ODI 评分：术后优良率和末次随访优良率分别为%和%。随访时间 6～18 个月(平均 11 个月)，随访率 100%, 融合率 100%。融合节段椎间隙前凸角度°±°，动力位片术前椎间活动域为°±°，术后椎间活动域为°±°，两者差异有统计学意义()。无融合器脱出、塌陷、移位等并发症。结论 撑开型椎间融合器治疗腰椎不稳症, 具有手术简单、创伤小和疗效好等优点。【关键词】 腰椎不稳症 椎间融合术 融合器 【Abstract】 Objective To explore the clinical effect of expandable interbody fusion cage (EIFC) in treating lumbar spine instability syndrome(LSIS). Methods The clinical effect was evaluated with the Oswestry disability index (ODI), including the symptom of pre operation and post operation, the lumbar interbody lordosis angle, domain of sagittal rotation of the interbody on X ray, fusion rate and complications. Results According to the ODI, excellent rates were % (post operation) and % (the last follow up). All were followed up from 6 months to 18 months and fusion rate was 100%. Lumbar interbody lordosis angle was °±°. The dynamic domain of sagittal rotation of pre operation was °±° and post operation °±°。There is statistical significance(). No complication with interbody fusion cage prolapse, sink and dislocation was happened. Conclusion Application of EIFC to treat LSIS is simple mini invasive surgery and has good clinical outcome. 【Key words】 Lumbar spine instability syndrome； Interbody fusion； Expandable cage 腰椎不稳症是指腰椎节段活动时超过正常范围、活动性质改变而引起相应的临床表现和潜在脊柱进行性神经损害。其手术治疗包括术...
