The incidence of massive early subsidence (subsidence greater than 10 mm) following impaction grafting of the femur in revision surgery is reported. The first 79 consecutive revision total hip arthroplasties using morselized allograft, polymethyl methacrylate cement, and a double-tapered, polished, collarless stem were reviewed. Nine (11%) of the 79 revision femoral prostheses showed massive subsidence, with another nine hips subsiding to a lesser degree. Further elucidation of the critical factors contributing to the initial stability of the biologic composite is required.
报告了翻修手术中股骨打压植骨后大量早期下沉（下沉超过10毫米）的发生率。回顾了连续79例首次使用颗粒状同种异体骨、聚甲基丙烯酸甲酯骨水泥和双锥度、抛光、无领柄的全髋关节置换翻修手术。79个股骨假体中有9个（11%）出现大量下沉，另有9个髋关节下沉程度较轻。需要进一步阐明影响生物复合材料初始稳定性的关键因素。
