The Corail® cementless stem (DePuy Synthes) has been used in Norway since 1987 and is one of the most frequently used stems in THA worldwide. Although the published survival results of the standard Corail stem have been good, little is known about the long-term (more than 20 years) survival of other stem design variants. Further, some changes were made to the extramedullary part of the stem in 2003, and the effect of these changes on survival is unknown.

不同 Corail 股骨柄型号的植入物存活率有何不同？挪威关节置换术登记处对 51,212 例病例进行长达 30 年随访的结果。

Corail® 非骨水泥假体柄 (DePuy Synthes) 自 1987 年以来一直在挪威使用，是全球 THA 中最常用的假体柄之一。尽管已公布的标准 Corail 柄的生存结果良好，但对其他柄设计变体的长期（超过 20 年）生存情况知之甚少。此外，2003年对茎的髓外部分进行了一些改变，这些改变对存活率的影响尚不清楚。
