The vascularization, innervation and termination of the clavicular portion of the pectoralis major muscle were studied by dissection of 7 adult subjects and 2 fetuses. The vascular and nervous autonomy of the clavicular portion was confirmed. Blood-supply was effected by 2 arteries and innervation by an independent nerve. The exact distribution of the fibers composing the pectoralis major and their complex insertion are described. It is concluded that the clavicular portion can be employed as an active muscle transplant to the head of the humerus when the short rotator muscles of the shoulder are ineffective.
通过对7名成年受试者和2名胎儿进行解剖，研究了胸大肌锁骨部的血管分布、神经支配和止点。证实了锁骨部的血管和神经自主性。血液供应由2条动脉完成，神经支配由一条独立的神经完成。描述了构成胸大肌的纤维的确切分布及其复杂的附着情况。得出的结论是，当肩部的短旋转肌功能不佳时，锁骨部可作为一块活性肌肉移植到肱骨头。
