摘　　要：目的探讨人工股骨头置换术后股骨头脱位的发生原因，为提高疗效、减少并发症提供参考。方法回顾性分析14年间151例（156髋）老年患者接受人工股骨头置换术后发生股骨头脱位的情况。结果对本组患者进行平均（46±25）个月的随访（6—84个月）。151例患者（156髋）中有7例患者发生股骨头脱位，占4．49％，其中3例患者发现存在假体安装匹配不良及手术操作失误的情况，2例患者伴有帕金森疾病，全部脱位的患者均并存多种老年内科疾病。结论假体安装匹配不良及手术操作失误是发生脱位的首要原因。老年人的伴发病与人工股骨头置换术后脱位的发生也具有一定的相关性，在治疗时要加以重视及预防。Objective In this retrospective series, we analysised the reasons of dislocation after artificial femoral head replacement. Methods Form January 1985 to August 2008, 156 hips of 151 patients were treated with artificial femoral head replacement, and they were reviewed. Results Mean follow-up period was （46 ± 25 ） months （ range 6-84 ）. Dislocation of the femoral head prosthesis was observed in 7 cases （4.49%）. The wrong matching of prosthesis is the most important factors. There were 2 cases with Parkinson＇ s disease and all cases with nervous system disease. Conclusions Incorrect place of femoral head prosthesis was the mainly reason of dislocation. Nervous system diseases were related to the dislocation, Preventive measures must be taken to reduce the undesirable side-effects that derived from nervous system disease.
