To determine the outcome of 1951 total hip arthroplasties performed between 1980 and 1991 at Middlemore Hospital.
An independent retrospective review was carried out between 1993 to 1995 giving a minimum follow-up of two years. Useable data were obtained for 96.8% of cases.
The overall wound infection rate was 3.4% (n=65), and of these seven (10.8%) required revision. The revision rate for infection for all patients was 1.16% (n=22). The in-hospital dislocation rate was 2.6% (n=49), and of these five (9.8%) required revision. Patient pain, activity and satisfaction were acceptable. Revision was required for 163 patients (8.7%), mainly for loosening. A survival analysis of the commonly used implants at seven years matched results from other studies. (Stem survival: Spectron 99.5%, Charnley 95.6%. Cup survival: Spectron 97.9%, Charnley 98.1%). Analysis of outcome predictors showed that youth and weight both influence the rate of revision.
Results in terms of patient satisfaction and revision rates were comparable with other published series. The wound infection rate was higher than desirable, but not unexpected in view of the number of surgeons involved (73) and the lack of special theatre facilities.
确定1980年至1991年间在米德尔莫尔医院进行的1951例全髋关节置换术的结果。
1993年至1995年进行了独立的回顾性研究，至少随访两年。96.8%的病例获得了可用数据。
总体伤口感染率为3.4%（n = 65），其中7例（10.8%）需要翻修。所有患者的感染翻修率为1.16%（n = 22）。院内脱位率为2.6%（n = 49），其中5例（9.8%）需要翻修。患者的疼痛、活动能力和满意度均可接受。163例患者（8.7%）需要翻修，主要原因是假体松动。对常用假体进行的七年生存分析结果与其他研究相匹配。（柄的生存率：Spectron为99.5%，Charnley为95.6%。髋臼杯的生存率：Spectron为97.9%，Charnley为98.1%）。结果预测因素分析表明，年龄和体重均会影响翻修率。
在患者满意度和翻修率方面的结果与其他已发表的系列研究相当。伤口感染率高于预期，但鉴于参与手术的外科医生数量（73名）以及缺乏特殊的手术设施这一情况，也在意料之中。
