摘要(Abstract)：

[目的]使用双能X线骨密度仪(DEXA)测量9例人工髋关节翻修病人股骨近端假体周围骨密度,了解人工髋关节翻修病人假体周围骨丢失情况。[方法]因假体松动而接受初次人工全髋关节翻修手术病人9例,用双能X线骨密度仪(DEXA)对比测量双侧股骨近端骨密度,测量区域的划分采用Gruen七区法。术前临床评估以Harris髋关节评分(HHS)为标准。[结果]9例病人HHS评分61分,DEXA测量结果发现所有病人手术侧骨密度较非手术侧均出现明显下降,范围在8.9%~27.6%,平均15.4%,下降有统计学意义(P<0.05)。[结论]人工髋关节置换术后早中期失败的病人,股骨近端假体周围骨丢失明显。
