Abstract

BACKGROUND

Our aim was to elucidate the dislocation rate after total hip arthroplasty at Haugesund County Hospital, Norway.

MATERIAL AND METHODS

Information was obtained from the Norwegian Arthroplasty Register and from hospital patient files. All 1,076 patients (781 female) operated at the hospital 1987-2000 were included. The ITH prosthesis was used in 545 patients and the Charnley prosthesis with a smaller head in 531 patients.

RESULTS

21 patients (2.0%) experienced dislocation after total hip arthroplasty, 17 during activities of daily living and three after a fall. 17 dislocations happened within six months postoperatively. The dislocation risk was smaller for women than for men (1.3% vs 3.7%, p = 0.01). Patients with a Charnley prosthesis had a greater risk for recurrent luxations than those with a ITH prosthesis (1.7% vs 0.2%, p = 0.01).

INTERPRETATION

The rate of dislocation after total hip arthroplasty in this study is similar to that of other reports in the literature.

摘要

背景

我们的目的是阐明挪威豪格松郡医院全髋关节置换术后的脱位率。

材料与方法

从挪威关节置换登记处和医院患者档案中获取信息。纳入了1987年至2000年在该医院接受手术的所有1076例患者（781例女性）。545例患者使用了ITH假体，531例患者使用了小头的Charnley假体。

结果

21例患者（2.0%）在全髋关节置换术后发生脱位，17例发生在日常生活活动中，3例在跌倒后发生。17例脱位发生在术后6个月内。女性的脱位风险低于男性（1.3%对3.7%，p = 0.01）。使用Charnley假体的患者复发性脱位的风险高于使用ITH假体的患者（1.7%对0.2%，p = 0.01）。
