| 摘 要： | 背景:多数情况下行后路腰椎椎间融合患者发生Cage移位需再次手术翻修,但翻修手术难度大,效果也常不确切。目的:分析影响后路腰椎椎间融合后Cage移位的相关因素。方法:回顾性分析中南大学湘雅三医院2004-01/2010-01进行后路腰椎椎间融后发生Cage移位的16例患者及由外院转入的4例同类患者的临床资料,观测病变节段内置入Cage的数目、Cage的置入深度、Cage与椎体终板贴合程度、椎弓根钉系统的稳定性及病变节段椎间隙高度恢复情况等指标。结果与结论:病变节段使用单枚Cage融合9例,使用双Cage融合11例。Cage置入深度不足者12例,Cage与椎体终板贴合不佳者10例、病变节段椎间隙高度未恢复者8例,椎弓根钉置入位置错误者2例,椎弓根钉螺帽松动者4例。结果说明Cage的设计、选择、初始置入位置,椎间隙高度的恢复及配合应用椎弓根钉系统的情况可能影响Cage在宿主体内的稳定性。
