Distal interphalangeal joint arthroplasty is effective in alleviating the pain of degenerative arthritis while preserving motion and stability. This procedure is undertaken as an alternative to arthrodesis of this joint. This is a review of this procedure done in 38 digits. The average age of the patients at the time of operation was 58.3 years. The implants have been in place for a mean period of 10 years. Less than 10% of the implants have had to be removed. The outcome measures of range of motion indicate that the distal interphalangeal joint moves 33 degrees. Compared with arthrodesis, silicone interpositional arthroplasty offers the advantage of retained motion while preserving stability.
远侧指间关节置换术在缓解退行性关节炎疼痛的同时，能够保留关节活动度和稳定性。该手术可作为此关节融合术的替代方案。本文回顾了38个手指所做的该手术。患者手术时的平均年龄为58.3岁。植入物平均在位时间为10年。不到10%的植入物需要取出。活动度的结果测量表明，远侧指间关节可活动33度。与关节融合术相比，硅胶置入关节成形术具有保留活动度并保持稳定性的优势。
