摘　　要：目的:探讨PLIF术后椎间融合器移位的原因及对策。方法:对我院2005年1月-2013年1月我科收治的PLIF术后并发椎间融合器移位的8例患者(2例本院术后,6例外院术后)进行术前、术后影像学分析,分析术后移位的方向及程度,并对向椎管内移位的病例进行翻修术。结果:8例患者中,1例向侧方移位,7例向后方移位(其中2例由钉棒松动引起、3例由于椎间植骨床处理不够、2例术中放置融合器位置不佳)。结论:PLIF术后椎间融合器移位的原因复杂,一旦发生要正确分析可能的原因,进行适合的翻修术,避免医疗纠纷的发生。Objective：To discuss the reason and treatment of cage migration after posterior lumbar interbody fusion （PLIF）. Methods： A total of 8 patients with cage migration after PLIF were collected from January 2005 to January 2013. The clini-cal data before and after surgery were obtained. The orientation and degree of cage migration were analyzed. The patients with cage displaced towards vertebral canal were treated with revision surgery. Results：Of all the 8 patients, one presents with lateral displacement and 7 present with posterior displacement. 2 cases of cage migration were caused by loosening of screws, 3 by insufficient intervetebral preparation and 2 by inappropriate placement. Conclusion：There are many reasons in cage migration after PLIF and surgeons should analyze the reason and consider revision surgery. Proper revision could avoid medical disputes.
