Silicone arthroplasty for proximal interphalangeal joint ankylosis is rarely performed, partly due to the potential for lateral joint instability. We present our experience performing proximal interphalangeal joint arthroplasty for joint ankylosis, using a novel reinforcement/reconstruction technique for the proper collateral ligament. Cases were prospectively followed-up (median 13.5 months, range 9-24) and collected data included range of motion, intraoperative collateral ligament status and postoperative clinical joint stability; a seven-item Likert scale (1-5) patient-reported outcomes questionnaire was also completed. Twenty-one ankylosed proximal interphalangeal joints were treated with silicone arthroplasty, and 42 collateral ligament reinforcements undertaken in 12 patients. There was improvement in range of motion from 0° in all joints to a mean of 73° (SD 12.3); lateral joint stability was achieved in 40 out of 42 of collateral ligaments. High median patient satisfaction scores (5/5) suggest that silicone arthroplasty with collateral ligament reinforcement/reconstruction should be considered as a treatment option in selected patients with proximal interphalangeal joint ankylosis.

硅酮关节成形术治疗近侧指间关节僵直很少进行，部分原因是存在侧向关节不稳定的潜在风险。我们介绍了使用新型加固/重建技术治疗侧副韧带来进行近侧指间关节关节成形术的经验。对病例进行了前瞻性随访（中位数 13.5 个月，范围 9-24 个月），收集的数据包括活动范围、术中侧副韧带状况和术后临床关节稳定性；还完成了一个 7 项李克特量表（1-5）的患者报告结果问卷。21 个僵直的近侧指间关节接受了硅酮关节成形术治疗，12 名患者中有 42 个侧副韧带接受了加固。所有关节的活动范围从 0°增加到平均 73°（标准差 12.3）；42 个侧副韧带中有 40 个实现了侧向关节稳定性。高的中位数患者满意度评分（5/5）表明，硅酮关节成形术联合侧副韧带加固/重建应被视为治疗近侧指间关节僵直的一种选择，尤其适用于特定患者。
