Periprosthetic joint infection occurs frequently after total hip replacement, and the antibiotic-impregnated hip spacers is the golden standard in treatment of hip joint infections, though accompanied by a series of complications . Among which, the spacer fractures and dislocations are the most commonly seen mechanical complications probably caused by several risk factors such as acetabular deficiency, fixation instability onto the proximal femur, peripheral soft tissues defect of joints and mismatched spacer geometry. Over the past two decades, many technical aspects as well as practical tips and pearls have been found to overcome the mechanical complications of hip spacer implantation to the minimum.%假体周围感染是全髋关节置换术后常见并发症,抗生素骨水泥占位器二期翻修是治疗假体周围感染的金标准,但也会产生一系列的并发症.其中占位器脱位和断裂是最为常见的机械性并发症,诸多因素可能会引起占位器机械性并发症的发生,如髋臼侧骨缺损、股骨近端固定不牢、关节周围软组织的缺失、占位器头部的几何形状不佳.近年的研究总结了许多手术技巧和方法 ,可使该并发症的发生率降到最低.
