The distal radioulnar joint (DRUJ) is a complex structure that contributes to full, painless forearm rotation and weight bearing. Stability requires adequate bony architecture and robust soft-tissue support. Arthritis of the DRUJ between the sigmoid notch of the distal radius and the ulnar head can be caused by traumatic, inflammatory, congenital, and degenerative processes. Initial management of symptomatic DRUJ arthritis is nonsurgical. Surgery is reserved for patients with refractory pain. Although outcomes typically are positive following excision of the distal ulna, serious potential postoperative complications include instability and potentially painful impingement of the residual distal ulnar stump. Procedures used to manage the unstable residual ulna include soft-tissue stabilization techniques and DRUJ implant arthroplasty.
远端尺桡关节（DRUJ）是一个复杂的结构，有助于完全无痛的前臂旋转和承重。稳定性需要足够的骨骼结构和强壮的软组织支撑。桡骨远端的月状窝和尺骨头之间的 DRUJ 关节炎可由创伤、炎症、先天和退行性过程引起。有症状的 DRUJ 关节炎的初始治疗是非手术的。手术保留给有难治性疼痛的患者。尽管切除尺骨远端后通常结果是积极的，但严重的潜在术后并发症包括不稳定和残留尺骨远端残端潜在疼痛的撞击。用于处理不稳定的残留尺骨的手术包括软组织稳定技术和 DRUJ 植入物关节成形术。
