The distal radioulnar joint (DRUJ) is a complex structure that participates in forearm rotation and weight-bearing. Myriad disorders affect the DRUJ and present diagnostic and management challenges. Degenerative and posttraumatic arthritis and pain at the DRUJ have been traditionally treated with resection of 1 of the 2 arthritic surfaces. Although the procedure often relieves pain associated with incongruence, it creates a different problem by changing the overall dynamics of the forearm rotation and weight-bearing, resulting in radioulnar convergence and ulnar translation of the carpus. This article focuses on the management of painful radioulnar convergence after distal ulnar resections.
下尺桡关节（DRUJ）是一个复杂的结构，参与前臂旋转和负重。多种疾病会影响下尺桡关节，并带来诊断和治疗方面的挑战。传统上，下尺桡关节的退行性和创伤后关节炎及疼痛通过切除两个关节炎性表面之一来治疗。尽管该手术通常能缓解与关节不匹配相关的疼痛，但它通过改变前臂旋转和负重的整体动力学，引发了另一个问题，导致桡尺汇聚和腕骨的尺侧移位。本文重点关注尺骨远端切除术后疼痛性桡尺汇聚的治疗。
