Proximal interphalangeal joint resection arthroplasty with Swanson's implant should be considered as a simplified new hinge joint with a simplified shorter but isometric extensor system which will work if the flexor system is intact. The procedure is indicated in cases of severe, ill-tolerated, fixed joint contractures. Functional improvement with restoration of some range of motion can be expected. Patients should be aware that they will not regain a complete range of motion at the PIP joint, there will be limited involvement of the distal interphalangeal joint, and there may be some discomfort in cold weather. The procedure is not recommended for patients with a high risk of postoperative dystrophy, on workmen's compensation, or unable to understand the goals and limitations of a joint resection arthroplasty.
采用斯旺森植入物的近端指间关节切除成形术应被视为一种简化的新型铰链关节,其伸肌系统简化且较短但等长,前提是屈肌系统完整,该系统就能发挥作用。该手术适用于严重的、耐受性差的、固定性关节挛缩病例。有望通过恢复一定活动范围来改善功能。患者应明白,近端指间关节无法恢复完全的活动范围,远端指间关节受累有限,且在寒冷天气可能会有一些不适。对于术后营养不良风险高、领取工伤赔偿或无法理解关节切除成形术目标和局限性的患者,不建议进行该手术。
