We present a rare case of an accessory muscular slip originating from pectoralis major and inserting onto the medial epicondyle of the humerus and the medial brachial intermuscular septum. According to the current nomenclature this muscle is defined as a chondroepitrochlearis; however, we propose a new nomenclature: thoracoepicondylaris. This term more accurately reflects the origin and insertion of this, and the few similar cases that have been reported in the literature. Clinical considerations of such a variation include ulnar nerve entrapment and functionally limited abduction of the humerus.
我们报告了一例罕见病例，一块副肌束起自胸大肌，止于肱骨内上髁和臂内侧肌间隔。根据目前的命名法，这块肌肉被定义为软骨上髁肌；然而，我们提出一个新的命名：胸上髁肌。这个术语更准确地反映了该肌肉的起止点，以及文献中报道的少数类似病例。这种变异的临床考虑因素包括尺神经卡压和肱骨外展功能受限。
