We report a case of irreducible chronic volar dislocation of the distal radioulnar joint (DRUJ) after surgery for distal radius fracture. The patient underwent volar locking plate fixation for distal radius fracture. Despite the satisfactory alignment of the distal radius, irreducible volar dislocation of the DRUJ was discovered at 5 weeks after the initial surgery. DRUJ reconstruction at 9 weeks after injury using the Adams-Berger procedure resulted in a stable and functional DRUJ and wrist.
To prevent postoperative DRUJ instability or dislocation, the DRUJ should be evaluated for stability immediately after fracture fixation.
我们报告了一例桡骨远端骨折手术后慢性掌侧桡尺远侧关节（DRUJ）不可复位脱位的病例。患者因桡骨远端骨折接受了掌侧锁定钢板固定。尽管桡骨远端的对线良好，但在初次手术后 5 周时发现 DRUJ 出现不可复位的掌侧脱位。在受伤后 9 周时使用 Adams-Berger 手术进行 DRUJ 重建，结果 DRUJ 稳定且功能良好。
为了防止术后 DRUJ 不稳定或脱位，骨折固定后应立即评估 DRUJ 的稳定性。
