One hundred sixty-one dislocations after cemented total hip arthroplasty, with a mean follow-up period of 8 years after dislocation, were reviewed with the aim of establishing the prognosis. There were 84% single and 16% recurrent dislocations. Closed reduction was successful in 81% of cases. Thirty-seven percent of dislocations were early (within 5 weeks), 36% occurred in patients who had had previous surgery, and in 47% there was nonunion of the trochanter. There was a two-way interaction between these factors, and all factors were significant for recurrent dislocation. Twenty-six (16%) recurrent dislocations required surgery. The most common causes of recurrent dislocation demonstrated at operation were component malposition (58%) and failure of the abductor mechanism (42%). In total, 96% of cases were successfully treated.
对161例骨水泥型全髋关节置换术后脱位患者进行了回顾性研究，平均随访时间为脱位后8年，目的是确定预后情况。其中84%为单次脱位，16%为复发性脱位。81%的病例闭合复位成功。37%的脱位发生在早期（5周内），36%发生在既往有手术史的患者中，47%存在转子不愈合。这些因素之间存在双向交互作用，所有因素对复发性脱位均有显著影响。26例（16%）复发性脱位需要手术治疗。手术中发现复发性脱位最常见的原因是假体位置不当（58%）和外展肌机制失效（42%）。总体而言，96%的病例得到了成功治疗。
