摘要
目的:介绍采用部分正中及尺神经束支移位,治疗臂丛C_(5、6)根性撕脱伤的疗效。方法:1994年起,在尸体标本上对肌皮神经与尺神经进行测量与研究,在此基础上,采用部分正中及尺神经束支移位与肌皮神经肌支吻接的方法,治疗7例C_(5、6)根性撕脱伤。结果:肱二头肌肌支与尺神经横截面积之比为1∶12。因此,从尺神经切取束支移位时,束支的粗细为供体神经的1/12即可。临床7例中,4例采用尺神经束支移位,3例采用正中神经束支移位。平均随访10个月,肱二头肌肌力恢复到4～5级。供区术后无神经功能障得。结论:采用部分正中及尺神经束支移位,与肌皮神经肌支吻接治疗臂丛C_(5、6)根性撕脱伤的方法是可行的,疗效较为满意。
Objective: To introduce a method of partial ulnar and median nerve transfer for C_(5、6) avulsion of the brachial plexus. Methods: Part of the ulnar and median nerve had been chosen to be transferred to musculocutaneous nerve in 7 patients based on the anatomical study on cadavers since 1994. Rcsults: Twelve percent of the cross area of the ulnar or medial nerve could be matched to the motor branch of the biceps. So twelve percent of the ulnar (4 cases) or medial nerve (3 cases) was harvested without significant impairment of hand function. The strength of biceps restored M_4 to M_5. Conclusions: Partial ulnar and median nerve transfer for C_(5、6) avulsion of the brachial plexus is feasible and effective.
