Instability of the distal radioulnar joint is a source of ulnar-sided wrist pain and functional impairment. Symptomatic instability may present acutely, after a recent traumatic injury, or in a delayed fashion as chronic instability following a history of a traumatic event. A detailed understanding of the complex anatomy, biomechanics, and stabilizing structures of the distal radioulnar joint is important to evaluate and treat acute and chronic instability. This article describes the pathophysiology of distal radioulnar joint instability with attention to the anatomic structures involved and provides information about evaluation and treatment.
桡尺远侧关节不稳定是引起尺侧腕部疼痛和功能障碍的一个原因。有症状的不稳定可能是急性的，发生在近期创伤性损伤之后，或者是慢性的，在创伤性事件发生后出现迟发性不稳定。详细了解桡尺远侧关节的复杂解剖结构、生物力学和稳定结构对于评估和治疗急性和慢性不稳定非常重要。本文描述了桡尺远侧关节不稳定的病理生理学，重点介绍了涉及的解剖结构，并提供了有关评估和治疗的信息。
