BACKGROUND The aim of this retrospective study was to evaluate the clinical, radiologic, and survival results of dual mobility (DM) sockets in revision total hip arthroplasty (THA) performed for instability versus revision THAs performed for other reasons. METHODS From a computerized database, we identified 84 revision THAs using a modern DM socket performed in 81 patients with a mean age of 71 years. Indication for revision was recurrent dislocation in 47 hips, and other reasons in the remaining 37 hips. A survivorship analysis according to the actuarial method was carried out on the entire series using revision for any cause, revision for dislocation, and radiological cup loosening revised or not, as the end points. RESULTS Of the 81 patients, twelve died, six were lost to follow-up, eight had been revised, and 55 patients (58 hips) were unrevised and alive at a mean follow-up of 6.4 years. Dislocation occurred in four of the 47 (8.5%) hips for which indication for revision was dislocation versus one of the remaining 37 (2.7%) hips [odds ratio = 3.4 (0.4-31.3), p = 0.07]. According to our criteria, three acetabular components of which one was revised were considered as loosened. When using revision for dislocation as the end-point, the survival rate at seven years was 90.4 ± 5.3% (IC95%, 79.9-100) in the 47 hips for which the indication for revision was dislocation versus 100% in the remaining 37 hips (log-rank, p = 0.5). CONCLUSIONS The current study indicated that DM sockets represent an interesting solution to prevent dislocation in revision THAs at mid-term follow-up.

翻修性全髋关节置换术中的双重活动性构造:复发脱位的生存率分析与其他适应症的随访时间为三至十二年。

背景技术这项回顾性研究的目的是评估因不稳定性而进行翻修全髋关节置换术(THA)与因其他原因进行翻修THA的双重活动(DM)托槽的临床,放射学和生存结果。方法从计算机数据库中,我们采用现代DM插座对81例平均年龄为71岁的患者进行了84次修订THA。翻修的指征是47髋反复脱位,其他原因是其余37髋。根据精算方法对整个系列进行了生存分析,使用任何原因的修订,错位的修订以及放射线杯松动的修订与否作为终点。结果在81例患者中,有12例死亡,6例失访,8例经修订,55例患者(58髋)未接受翻修,平均随访6.4年生存。脱位发生在47例(8.5%)髋关节中,其中有4例发生髋关节脱位,而其余37例(2.7%)髋关节之一[比值比= 3.4(0.4-31.3),p = 0.07]。根据我们的标准,三个髋臼组件(其中一个已修订)被认为是松动的。以翻修脱位为终点时,47髋的七年生存率为90.4±5.3%(IC95%,79.9-100),而脱位的指征是髋关节脱位,其余37髋为100%。 (对数等级,p = 0.5)。结论当前的研究表明,DM插槽是防止中期随访中修订THA脱位的有趣解决方案。脱位发生在47例(8.5%)髋关节中,其中有4例发生髋关节脱位,而其余37例(2.7%)髋关节之一[比值比= 3.4(0.4-31.3),p = 0.07]。根据我们的标准,三个髋臼组件(其中一个已修订)被认为是松动的。以翻修脱位为终点时,47髋的七年生存率为90.4±5.3%(IC95%,79.9-100),而脱位的指征是髋关节脱位,其余37髋为100%。 (对数等级,p = 0.5)。结论当前的研究表明,DM插槽是防止中期随访中修订THA脱位的有趣解决方案。脱位发生在47例(8.5%)髋关节中,其中有4例发生髋关节脱位,而其余37例(2.7%)髋关节之一[比值比= 3.4(0.4-31.3),p = 0.07]。根据我们的标准,三个髋臼组件(其中一个已修订)被认为是松动的。以翻修脱位为终点时,47髋的七年生存率为90.4±5.3%(IC95%,79.9-100),而脱位的指征是髋关节脱位,其余37髋为100%。 (对数等级,p = 0.5)。结论当前的研究表明,DM插槽是防止中期随访中修订THA脱位的有趣解决方案。根据我们的标准,三个髋臼组件(其中一个已修订)被认为是松动的。以翻修脱位为终点时,47髋的七年生存率为90.4±5.3%(IC95%,79.9-100),而脱位的指征是髋关节脱位,其余37髋为100%。 (对数等级,p = 0.5)。结论当前的研究表明,DM插槽是防止中期随访中修订THA脱位的有趣解决方案。根据我们的标准,三个髋臼组件(其中一个已修订)被认为是松动的。以翻修脱位为终点时,47髋的七年生存率为90.4±5.3%(IC95%,79.9-100),而脱位的指征是髋关节脱位,其余37髋为100%。 (对数等级,p = 0.5)。结论当前的研究表明,DM插槽是防止中期随访中修订THA脱位的有趣解决方案。
