The distal radioulnar joint is responsible for stable forearm rotation. Injury to this joint can occur following a variety of mechanisms, including wrist fractures, ligamentous damage, or degenerative wear. Accurate diagnosis requires a clear understanding of the anatomy and mechanics of the ulnar aspect of the wrist. Injuries can be divided into three major categories for diagnostic purposes, and these include pain without joint instability, pain with joint instability, and joint arthritis. New advancements in imaging and surgical technique can allow for earlier detection of injuries, potentially preserving joint function. In this article, the authors review the pertinent anatomy, biomechanics, and major abnormality involving the distal radioulnar joint.
桡尺远侧关节负责前臂的稳定旋转。该关节损伤可由多种机制引起，包括腕部骨折、韧带损伤或退行性磨损。准确的诊断需要清楚了解腕部尺侧的解剖结构和力学原理。为了诊断目的，损伤可分为三大类，包括无关节不稳定的疼痛、有关节不稳定的疼痛和关节关节炎。成像和手术技术的新进展能够更早地检测出损伤，有可能保留关节功能。在本文中，作者回顾了桡尺远侧关节的相关解剖结构、生物力学和主要异常情况。
