Abstract

The musculocutaneous nerve (MCN) is the terminal branch of the lateral cord of the brachial plexus, and emerges at the inferior border of pectoralis minor muscle. The nerve can interact with the median nerve (MN), adhering to the nerve and sharing fibers with it. During anatomical dissection of twelve cadavers, we have detected a rare variation of the anastomosis between MCN and MN. The knowledge of this anatomical variation could be of great relevance during surgical and clinical practices.
正中神经与肌皮神经的吻合:一种非常罕见的解剖变异,与传统的吻合比较
肌皮神经(MCN)是臂丛外侧索的末梢分支,发源于胸小肌的下缘。神经可与正中神经相互作用,与正中神经粘连并共享纤维。在对12具尸体的解剖中,我们发现了MCN和MN之间吻合的罕见变异。这种解剖变异的知识在外科和临床实践中可能有很大的相关性。
