摘要(Abstract)：

[目的]分析棘突间弹性固定装置翻修手术的原因。[方法]2009年3月～2013年10月,11例接受棘突间弹性固定装置(Wallis或Coflex)手术的患者于2010年12月～2016年12月因多种原因行翻修手术,初次手术及翻修手术均在本科完成。其中包括9例男性和2例女性,初次手术平均年龄57岁(26～77岁)。对比分析两次术前及术后的临床资料及X线片、CT或MRI等影像学资料。[结果]两次手术平均间隔3.75年。通过对临床及影像资料的分析,翻修手术的可能原因包括:不恰当的手术适应证、相邻节段病、棘突骨折或骨吸收以及慢性感染。其中,不恰当的手术适应证又包括重度腰椎管狭窄症、明显的局部节段不稳定、腰椎侧弯及严重骨质疏松。[结论]棘突间弹性固定装置(Wallis或Coflex)不恰当的手术适应证包含重度腰椎管狭窄症、明显的局部节段不稳定、腰椎侧弯及严重骨质疏松。在棘突间弹性固定装置置入术后,相邻节段病、棘突骨折或骨吸收以及慢性感染的问题应得到关注。
