A 26 year old man was referred to us with extensor pollicis longus dysfunction (EPL), and investigation revealed a fracture of the trapezium (left) and carpo-metacarpal joint dislocation of the thumb. Operative exploration revealed mechanical displacement of the tendon secondary to fracture dislocation of the trapezium as the cause for EPL dysfunction. The lesion was managed with an open reduction and screw fixation resulting in good functional outcome.
一名26岁男性因拇长伸肌功能障碍(EPL)前来我院就诊,检查发现(左侧)大多角骨骨折及拇指腕掌关节脱位。手术探查发现,大多角骨骨折脱位导致肌腱机械性移位,这是拇长伸肌功能障碍的原因。该病变通过切开复位和螺钉固定进行处理,功能恢复良好。
