This article reviews the anatomy and mechanics of pronation and supination (axial rotation) of the forearm through the distal radioulnar joint (DRUJ), and the proximal radioulnar joint (PRUJ). Injuries to the bones and/or ligaments of the forearm, wrist, or elbow can result in instability, pain, and limited rotation. Acute dislocations of the DRUJ commonly occur along with a fracture to the distal radius, radial metadiaphysis, or radial head. These injuries are all caused by high-energy trauma. Outcomes are predicated on anatomic reduction and restoration of stability to the DRUJ and PRUJ with or without ligamentous repair or reconstruction.
本文回顾了通过桡尺远侧关节（DRUJ）和桡尺近侧关节（PRUJ）前臂的旋前和旋后（轴向旋转）的解剖结构和力学原理。前臂、手腕或肘部的骨骼和/或韧带损伤可导致不稳定、疼痛和旋转受限。DRUJ 的急性脱位通常与桡骨远端、桡骨干骺端或桡骨头骨折同时发生。这些损伤均由高能创伤引起。其结果取决于 DRUJ 和 PRUJ 的解剖复位和稳定性的恢复，无论是否有韧带修复或重建。
