Twenty-one patients with recurrent dislocation of total hip arthroplasty were treated by trochanteric osteotomy and distal advancement of the greater trochanter. There were no malpositioned prostheses. In 17 patients no further dislocations occurred. One patient, who had the hip arthroplasty in a paretic leg, continued to dislocate after the osteotomy and the prosthetic components were removed 5 months after surgery. The remaining three patients became stable after further surgery: cup augmentation in one and reattachment of the greater trochanter in two. Advancement of the greater trochanter is recommended in patients with recurrent dislocation of their total hip arthroplasty when no apparent malposition of the prosthetic components can be identified.
21例全髋关节置换术后复发性脱位患者接受了转子截骨术及大转子远端推进术治疗。假体均无位置不当情况。17例患者未再发生脱位。1例在患侧麻痹下肢行髋关节置换术的患者，截骨术后仍继续脱位，术后5个月取出了假体组件。其余3例患者在进一步手术后恢复稳定：1例行髋臼扩大术，2例行大转子重新附着术。对于全髋关节置换术后复发性脱位且假体组件无明显位置不当的患者，建议行大转子推进术。
