The distal radioulnar joint (DRUJ) allows supination and pronation of the distal forearm and wrist, an integral motion in everyday human activity. DRUJ injury and chronic instability can be a significant source of morbidity in patients' lives. Although often linked with distal radius fractures, DRUJ injury may occur in a variety of other upper extremity injuries, as well as an isolated pathology. Diagnosis of this injury requires the clinician to have a high index of suspicion and low threshold for clinical testing and further imaging of the DRUJ. The purpose of this article is to provide a review on DRUJ anatomy and biomechanics, to discuss common diagnostic and treatment modalities, and to identify common injuries associated with DRUJ instability.
桡尺远侧关节（DRUJ）使前臂远端和腕部能够旋前和旋后，这是日常人类活动中的一项不可或缺的动作。DRUJ损伤和慢性不稳定可能是患者生活中发病的重要原因。尽管DRUJ损伤常与桡骨远端骨折相关，但它也可能发生于多种其他上肢损伤以及孤立性病变中。诊断这种损伤需要临床医生有高度的怀疑指数，并且对DRUJ进行临床检查和进一步影像学检查的阈值要低。本文的目的是对DRUJ的解剖结构和生物力学进行综述，讨论常见的诊断和治疗方法，并确定与DRUJ不稳定相关的常见损伤。
