在110侧成人下肢标本上,观察测量了股薄肌。按照保留股薄肌的神经,吻接其主要血管,将其半游离移植到对侧以改进已瘫痪的股四头肌功能的手术设计,进行了有关的应用解剖学分析。股薄肌的神经可游离长度约10cm,转移至对侧耻骨肌起点处约9cm,长度是够的;但转移至股直肌起点处距离约16cm,神经长度不足,只能再移植一段神经加以桥接。血管吻接的供区和受区条件较好,本文提供了有关数据。 In 110 adult lower extremity specimens observed and measured gracilis. Anatomical analysis was performed in accordance with the surgical design that preserved the gracilis nerves, kissing its major vessels, and semi-free transplanting it to the contralateral side to improve paraplegic quadriceps femoris function. Muscle gracilis nerve free length of about 10cm, transferred to the contralateral pubis pubic muscle at the starting point of about 9cm, the length is enough; but transferred to the starting point of rectus femoris about 16cm, lack of nerve length, can only be re-transplantation of a nerve to be bridging. Vascular access for the donor area and the receiving area is better, this article provides the data.
