The distal radioulnar joint plays a critical role in pronation and supination of the forearm and can be injured with traumatic axial loading of the wrist. This is a case report of a 36-year-old male who presented to the emergency department with left upper extremity pain after falling onto an outstretched arm. The physical exam showed swelling and decreased range of motion of the elbow and wrist due to pain. Radiographs demonstrated left posterolateral elbow dislocation and left dorsal distal radioulnar joint dislocation. The patient underwent a successful closed reduction and splinting of both the left elbow and left distal radioulnar joint with good outcomes on follow up a week later. Since elbow dislocations are usually easily recognized and commonly treated in the emergency department, this case report focuses on the rarer finding of associated distal radioulnar joint dislocation because these injuries are often underdiagnosed or missed on initial assessment.

桡尺远侧关节在前臂旋前和旋后中起关键作用，可因腕部创伤性轴向负荷而受伤。本文报告一例36岁男性病例，该患者因伸直手臂摔倒后出现左上肢疼痛，就诊于急诊科。体格检查显示，因疼痛导致肘部和腕部肿胀，活动范围减小。X线片显示左肘关节后外侧脱位及左桡尺远侧关节背侧脱位。患者成功接受了左肘关节和左桡尺远侧关节的闭合复位及夹板固定，一周后随访效果良好。由于肘关节脱位通常在急诊科容易识别且常得到治疗，本病例报告重点关注相关桡尺远侧关节脱位这一较罕见的发现，因为这些损伤在初次评估时往往易被漏诊或误诊。
