Presented herein is a case of an extremely rare muscle in the pectoral region. It involved an accessory muscular slip originating from the pectoralis major and inserting onto the medial epicondyle of the humerus and the medial intermuscular septum. According to the literature this muscle is defined as chondroepitrochlearis. The arterial and nervous supply to the muscle came from the lateral thoracic artery and the medial pectoral nerve, respectively. Clinical considerations of such a variation include ulnar nerve entrapment and functionally limited abduction of the humerus.
本文介绍了一例发生在胸肌区域的极其罕见的肌肉病例。它涉及一条起自胸大肌并止于肱骨内上髁和内侧肌间隔的副肌束。根据文献记载，这块肌肉被定义为软骨上髁肌。该肌肉的动脉和神经供应分别来自胸外侧动脉和胸内侧神经。这种变异的临床考量包括尺神经卡压和肱骨外展功能受限。
