Thirty-one patients (34 joints) with pain due to carpometacarpal joint derangement were reviewed 1/2 to 12 years after a trapezium replacement arthroplasty using a Swanson silicone prosthesis. At review, 25 hands were free from pain, and nine had some pain on exertion. Mobility and strength were generally well restored. The radiographic examination revealed 12 prosthesis-fractures, three dislocations, and five cases of incongruity. However, all patients were satisfied with the results of the operation.
对31例（34个关节）因腕掌关节紊乱而疼痛的患者进行了回顾性研究，这些患者在使用Swanson硅胶假体进行大多角骨置换关节成形术后1/2至12年接受了复查。复查时，25只手无痛，9只手在用力时有一些疼痛。活动度和力量总体恢复良好。影像学检查显示12例假体骨折、3例脱位和5例不匹配。然而，所有患者对手术结果均满意。
