摘　　要：目的为给大腿部创伤修复及肌瓣移植提供形态学依据。方法采用解剖剥离测量方法,对25具(共50侧)成人下肢标本的坐骨神经肌支进行自身比例定位研究。结果 1坐骨神经发出的各肌支主要以多支型出现率最多;2坐骨神经发出的各肌支主要集中于下肢的3段;3坐骨神经发出的各肌支进入各肌门的区位,均有倾向于以神经干为轴心近距离分布的规律。结论确定了坐骨神经肌支的危险区段和危险区位,以及开展带神经血管蒂肌瓣移植的肌支类型。Objective This study aimed to provide morphological data for the injury repair and transplantation of the muscular flap in the high. Methods An auto-proportion localization study of the muscualr branches of sciatic nerve was made in 25 adults by the anatomical dissection. Results The multi-trunk type was observed of maximal incidence in the muscular branches of sciatic nerve. Second, the muscular branches of sciatic nerve mainly located in the third segment of the lower limb. Third, the sub broaches arising from sciatic nerve innervated muscles were dis- tributed closely to the nerve trunk. Conclusion It will be helpful in determining the dangerous segments and the dangerous region of the muscular branches of sciatic nerve, and the type of the muscular flap with transplanted nerves and blood vessels.
