Isolated volar dislocation of the distal radioulnar joint may result from a variety of injuries. This injury is incorrectly diagnosed in approximately 50% of presented cases. A case of volar dislocation of the distal radioulnar joint by traumatic hypersupination is presented. The clinical diagnosis may be hindered by marked swelling, pain, and limitation of motion of the wrist. Dislocation can be diagnosed by accurately obtained anteroposterior and lateral roentgenograms. Closed reduction with direct pressure over the ulnar head from a volar to dorsal direction and simultaneous distraction of the wrist is the preferred method of treatment.
尺桡远侧关节孤立性掌侧脱位可能由多种损伤引起。在大约50%的就诊病例中，这种损伤被误诊。本文报告一例因创伤性过度旋前导致的尺桡远侧关节掌侧脱位。明显的肿胀、疼痛和腕关节活动受限可能会妨碍临床诊断。通过准确获取的前后位和侧位X线片可诊断脱位。从掌侧到背侧直接按压尺骨头并同时牵引腕关节进行闭合复位是首选的治疗方法。
