We analysed the fate of 43 de la Caffinière prostheses implanted for arthrosis of the first carpometacarpal joint after a follow-up of 63 months (range 45 to 81). Ten prostheses failed. Further eight patients were lost for follow up. In the remaining 25 patients the rate of tilting of the cups (92%) was extremely high and the survival rate disappointing: 66% at 68 months. The prostheses were implanted in cancellous bone and the ball and socket reduces the moving axes of the normal joint to one center of rotation. These factors might explain the higher rate of loosening of the cups (28%), compared to 15% for the stems. In contrast, the clinical results were comparable with other operative procedures. The advantage is the brief postoperative rehabilitation period. Accordingly, this prosthesis can not be universally recommended and should be reserved for elderly patients, who must not undertake strenuous work.
我们分析了43个用于第一掌腕关节关节炎的德拉卡菲尼埃假体在随访63个月（范围45至81个月）后的情况。10个假体失败。另有8名患者失访。在其余25名患者中，髋臼倾斜率（92%）极高，生存率令人失望：68个月时为66%。假体植入松质骨，球窝将正常关节的运动轴减少到一个旋转中心。这些因素可能解释了髋臼松动率较高（28%）的原因，而柄的松动率为15%。相比之下，临床结果与其他手术方法相当。优点是术后康复期短。因此，这种假体不能被普遍推荐，应保留给不从事繁重工作的老年患者。
