摘　　要：目的通过对正中神经指浅屈肌肌支和尺神经运动支的解剖学研究，为正中神经指浅屈肌肌支移位修复尺神经运动支，恢复手内在肌功能的临床应用提供解剖学基础。方法选用20例40侧近期经福尔马林浸泡固定的成人上肢标本．暴露正中神经、尺神经，测量正中神经指浅屈肌肌支各项解剖学数据；应用图像分析系统对组织切片做定量分析，测算该肌支有髓神经纤维数目。临床模拟操作正中神经指浅屈肌肌支移位修复尺神经运动支。结果正中神经第4肌支发出部位距离桡骨茎突和尺骨茎突连线（48．4±2．4）mm，入肌部位距离桡骨茎突和尺骨茎突连线（21．4±1．8）mm，可分离长度（27．1±1．2）mm，横径（1．2±0．2）mm，前后径（0．7±0．1）mm；尺神经的运动支和感觉支之间自然分束无损伤分离长度为（7．I±0．70）cm；组织切片及图片系统测得正中神经指浅屈肌第4肌支有髓神经纤维数目为（1378．9±107．9）条。结论正中神经指浅屈肌第4肌支可修复尺神经运动支，以期恢复手内在肌的功能。Objective To provide a good anatomical foundation for transposition of the branch of median nerve superficial flexor muscle repairing the movement branch of ulnar nerve to recover the function of intrinsic muscle,by anatomic study of the muscle branch of the superficial flexor muscle of the median nerve and the movement branch of ulnar nerve. Methods Twenty adult upper limb specimens immersed fixed by formalin were elected and expose the midian nerve and ulnar nerve. Then every anatomical index was measured. Simulate to manipulate that the branch of superficial flexor muscle repair the motor branch of ulnar nerve. Calculate the number of myelinated nerve fibers of the branch of superficial flexor muscle. Results The distance between the position into muscle and styloid process of radius and styloid process of ulna： （21.4＋_1.8） ram, the distance that can be separated： （27.1±1.2）mm, the transverse diameter： （l.2-＋0.2）mm, anteroposterior diameter： （0.7 ± 0.1 ）mm. No injuJy separated distance between the sensory branch and motor branch of ulnar nerve： （7.1 ± 0.7）era. The 4th muscular branches of median nerve flexor digitorum superficialis was 1378.9 ± 107.9. Conclusion The 4th muscular branches of median nerve flexor digitorum superficialis can be used to repair the motor branch of the ulnar nerve to recover the function of intrinsic muscle of hand.
