The purpose of this study was identification of the innervation of the medial humeral epicondyle which has not been described before. In 20 patients, the medial intermuscular septum was evaluated histopathologically: the nerve was identified in 15 specimens without S-100 staining, and in the remaining 5 with S-100 staining. In six fresh cadavers, bilateral dissections identified the source of this nerve as the radial nerve in the axilla, coursing adjacent to the ulnar nerve in the upper arm, then moving laterally to be superficial to, or within, the medial intermuscular septum, until the nerve terminated in the periosteum of the medial humeral epicondyle, at the origin of the flexor-pronator muscle mass. In one specimen, a branch from the ulnar nerve in the axilla contributed to this nerve to the medial humeral epicondyle.
本研究的目的是确定之前未被描述过的肱骨内上髁的神经支配情况。对20例患者的内侧肌间隔进行了组织病理学评估：在15个标本中未进行S-100染色就识别出了神经，其余5个标本进行了S-100染色。在6具新鲜尸体上进行双侧解剖，确定该神经的来源为腋窝处的桡神经，它在上臂与尺神经相邻走行，然后向外移动至内侧肌间隔表面或其内部，直至该神经在屈肌-旋前肌肌群起点处的肱骨内上髁骨膜处终止。在1个标本中，腋窝处尺神经的一个分支对该至肱骨内上髁的神经有贡献。
