1、可膨胀性椎间融介器在腰椎退行性疾病治疗中的临床应用［摘耍］冃的：探讨可膨胀性椎间融合器治疗腰椎追行性疾病的效果。方法：2009年4月〜2010年5月我院对50例患者采用可膨胀性椎间融合器治疗腰椎退行性疾病，其屮采用后路椎间盘镜下操作治疗的有41例，采用后外侧经皮穿治疗的有9例。冋顾性分析其临床资料，对其治疗效果、植骨融合率、椎间隙高度及并发症等进行分析。结果：术后随访吋间8〜38个月，平均16个月，按照Odom标准对治疗效果进行评价。结果显示，36例为优，占72%；9例为良，占18%；4例为可，占
2、8%；1例为差，占2%。患者的症状得到明显改善，其优良率达90%。CT影像显示椎间盘突出并椎管严重狭窄，椎间融合器没有移位现象，与骨已融合，椎间高度没冇明显下降。术后对患者进行随访仅冇3例出现并发症，占6%。结论：可膨胀性椎间融合器治疗腰椎退行性疾病，具有创伤小、安全性高、融合率高、恢复良好等优点，具有很好的应用前景，值得进行临床推广应用。［关键词］可膨胀性椎间融合器；腰椎退行性疾病；临床应用［中图分类号］R681.5［文献标识码］B［文章编号］1673-7210(2011)12(b)-180-0
