【摘要】：正患者,男,22岁,因右腕背刀砍伤2h于2015年1月17日入院。体格检查:右腕背桡侧斜行约3.5 cm左右伤口,边缘整齐,轻度污染,肌腱断端外露。拇指掌指关节活动稍受限,指间关节伸屈功能无异常,外展功能稍限。手背桡侧和桡侧2个半手指背侧指间关节近端的皮肤感觉麻木。桡动脉搏动良好,其余各指运动及感觉功能无异常。各指末梢血运充盈良好。送手术室在臂丛麻醉下,手术探查发现:伸肌支持带斜行断裂,拇长展肌腱、拇短伸肌腱及桡神经浅支断裂,桡侧腕长、腕短伸肌腱及正常拇长伸肌腱未见断裂,另发现伤口远侧端有一肌腱与拇短伸肌腱伴行,肌键宽度、厚度与正常拇长伸肌腱相当(见图1)。牵拉

Physical examination: the right dorsal radial side of the right wrist oblique about 3.5 cm about the wound, the edge is neat, slightly contaminated, the tendon was exposed at the broken end. The movement of metacarpophalangeal joint of thumb was limited, the extension and flexion function of interphalangeal joint was not abnormal, and the abduction function was limited. Skin numbness at the proximal end of the dorsal interphalangeal joint of the dorsal and radial sides of the hand. The radial artery pulsated well and the other fingers had no abnormal motor and sensory function. The end of each finger blood flow is good. Under brachial plexus anaesthesia, the surgical exploration found that the extensor spurs had oblique rupture, the extensor pollicis longus tendon, the extensor pollicis brevis tendon and the superficial branch of the radial nerve, the length of the radial wrist, the extensor carpi brevis tendon and the normal extensor pollicis longus tendon were not broken. It was also found that there was a tendon at the distal end of the wound accompanied by the extensor pollicis brevis tendon, and the width and thickness of the muscle bond were similar to those of the normal extensor pollicis longus tendon (see figure 1).
