To validate a functional hand evaluation and to obtain an historical control group in a project of metacarpophalangeal total joint prosthesis, we reviewed our experience over a ten year period of Swanson's metacarpophalangeal joint arthroplasty in rheumatoid arthritis. Forty-nine implants in fourteen rheumatoid arthritis patients were reviewed clinically, radiologically and evaluated by the Arthritic Hand Function Test. The mean follow up was 4.5 years. All patients were ready to repeat the experience except one. The mean metacarpophalangeal joint range of motion was 37 degrees (18 degrees to 55 degrees) with a mean of 7 degrees ulnar deviation. Although their functional performance was 50% of normal, all patients completed the test. The strength was generally greater on the operated side. The low complication rate (6% fracture rate) with the successful functional outcome of Swanson's metacarpophalangeal joint arthroplasty in rheumatoid arthritis will be the gold standard for any new implant to develop.
为了验证一项功能性手部评估，并在一项掌指全关节假体项目中获得一个历史对照组，我们回顾了我们在十年间对类风湿关节炎患者施行了斯旺森掌指关节置换术的经验。对14例类风湿关节炎患者的49枚植入物进行了临床、放射学检查，并通过关节炎手部功能测试进行评估。平均随访时间为4.5年。除1例患者外，所有患者都愿意再次接受该治疗。掌指关节平均活动范围为37度（18度至55度），平均尺偏7度。尽管他们的功能表现仅为正常的50%，但所有患者均完成了测试。患侧的力量通常更大。斯旺森掌指关节置换术在类风湿关节炎患者中并发症发生率低（骨折率为6%）且功能结局成功，这将成为任何新型植入物研发的金标准。
