Forty-four thumbs in thirty-four patients with rheumatoid arthritis were treated with a flexible implant arthroplasty of the metacarpophalangeal joint. After follow-ups ranging from two to six and a half years the results were rated good to excellent in forty-two thumbs since they were not painful, had an increased arc of motion of the metacarpophalangeal joint in a more functional range, and were more effective in the activities of daily living. The results in this series indicated that careful reconstruction of the extensor apparatus is essential, as well as stabilization of the interphalangeal joint either by arthrodesis or by tenodesis if there is a hyperextension deformity. Of the six patients who had a fusion of the metacarpophalangeal joint in one thumb and an arthroplasty in the other, five preferred the arthroplasty because the joint was stable and also had a useful arc of motion, while one noted no difference between the two thumbs.
对34例类风湿性关节炎患者的44根拇指进行了掌指关节柔性植入关节成形术治疗。经过2至6年半的随访，42根拇指的结果被评为良好至优秀，因为它们不痛，掌指关节在更功能化的范围内活动弧度增加，并且在日常生活活动中更有效。该系列结果表明，仔细重建伸肌装置至关重要，如果存在过伸畸形，通过关节融合术或腱固定术稳定指间关节也很重要。在6例患者中，1根拇指进行了掌指关节融合术，另1根进行了关节成形术，其中5例更喜欢关节成形术，因为关节稳定且有有用的活动弧度，而1例指出两根拇指之间没有差异。
