A survey of 43 cemented arthroplasties of the trapeziometacarpal joint with a la Caffinière prosthesis in 40 patients is presented. A 70% patient satisfaction rate was obtained, with a mean DASH score of 24.2. Good range of motion was preserved (opposition 9/10 on Kapandji's scale) and gripping force as well as key pinch force increased from 18 kg to 24 kg and from 5.3 to 6.0 kg respectively. However loosening was seen in 44% of the implants. Loosening was related to younger age. We conclude that despite good clinical outcome, radiographic loosening is a threat for the future of this implant.
本文介绍了对40例患者采用拉卡菲尼埃假体进行的43例大多角骨-第一掌骨关节骨水泥型关节成形术的调查。患者满意度为70%，平均DASH评分为24.2。保留了良好的活动范围（根据卡潘迪分级法，对掌为9/10），握力和捏力分别从18千克增加到24千克以及从5.3千克增加到6.0千克。然而，44%的植入物出现了松动。松动与年龄较轻有关。我们得出结论，尽管临床结果良好，但影像学上的松动对该植入物的未来构成威胁。
