Painful radioulnar convergence following resection of the distal ulna can produce substantial disability and prove a challenging surgical problem, particularly in the revision setting. The purpose of this study was to evaluate the outcome of a series of patients with chronic distal radioulnar joint instability or multiple prior procedures treated with linked distal radioulnar joint arthroplasty with the APTIS prosthesis. A series of ten patients were identified with a mean follow up of 4.0 years. At final follow-up nine of ten implants survived free from revision or removal, with patients experiencing good pain relief and functional outcomes, with reasonable overall satisfaction in all seven patients who returned the questionnaires. Despite the medium-term follow-up and small number of patients, our results suggest the linked distal radioulnar joint arthroplasty may be a viable option for treating painful radioulnar convergence following multiple failed procedures at the distal radioulnar joint.
尺骨远端切除术后出现的疼痛性桡尺关节融合可导致严重残疾，并成为一个具有挑战性的外科问题，尤其是在翻修手术中。本研究的目的是评估一系列患有慢性桡尺远侧关节不稳定或之前接受过多次手术的患者，使用APTIS假体进行连接式桡尺远侧关节置换术的效果。共确定了10例患者，平均随访4.0年。在最后一次随访时，10个植入物中有9个存活，无需翻修或取出，患者疼痛得到良好缓解，功能结果良好，在返回问卷的7名患者中总体满意度合理。尽管随访期为中期且患者数量较少，但我们的结果表明，对于桡尺远侧关节多次手术失败后出现的疼痛性桡尺关节融合，连接式桡尺远侧关节置换术可能是一种可行的选择。
