This study aimed to provide a comprehensive description of the arterial supply to the subscapularis (SSC) muscle. This will provide critical information for various surgical procedures. Ten specimens of embalmed Korean cadavers were dissected and subjected to modified Sihler's method to reveal the branching pattern of the arteries surrounding the subscapularis, and its intramuscular blood supply. The SSC muscle was generally supplied by branches from the subclavian artery (suprascapular artery, supraSA; circumflex scapular artery, CxSA; and dorsal scapular artery, dSA) and the axillary artery (subscapular artery, subSA; lateral thoracic artery, LTA; posterior circumflex humeral artery, PCxHA; and a branch of the axillary artery, AAbr). The anterior aspect of the muscle was supplied by the subSA, LTA, CxSA, supraSA, and AAbr. The posterior aspect of the muscle was supplied by the supraSA, PCxHA, and subSA. The dSA was more scarcely distributed than the other arteries. In two cases, the dSA supplied the portion of the muscle near the medial border of the scapular. The anterior side of the muscle tendon was supplied by the CxSA, and its posterior side was supplied by the PCxHA. The subSA can be considered to be the main branch supplying the SSA based on its distribution area of arteries. It was mostly situated within the lower region of the SSC. After distributing to the anterior surface of the SSC, some branches of the subSA reached the posterior surface as perforating branches. Clin. Anat. 32:642-647, 2019. © 2019 Wiley Periodicals, Inc.
本研究旨在全面描述肩胛下肌（SSC）的动脉供应。这将为各种手术提供关键信息。对 10 具韩国防腐尸体标本进行解剖，并采用改良的 Sihler 法显示围绕肩胛下肌的动脉分支模式及其肌内血液供应。SSC 肌肉通常由锁骨下动脉（肩胛上动脉，suprascapular artery，suprSA；旋肩胛动脉，circumflex scapular artery，CxSA；和背侧肩胛动脉，dorsal scapular artery，dSA）和腋动脉（肩胛下动脉，subscapular artery，subSA；胸外侧动脉，lateral thoracic artery，LTA；旋肱后动脉，posterior circumflex humeral artery，PCxHA；和腋动脉分支，AAbr）分支供应。肌肉的前侧由 subSA、LTA、CxSA、suprSA 和 A Abr 供应。肌肉的后侧由 suprSA、PCxHA 和 subSA 供应。dSA 的分布比其他动脉更为稀疏。在两个案例中，dSA 供应肩胛内侧缘附近的肌肉部分。肌肌腱的前侧由 CxSA 供应，后侧由 PCxHA 供应。subSA 可以根据其动脉分布区域被认为是供应 SSA 的主要分支。它大多位于 SSC 的下部区域。在分布到 SSC 的前表面之后，一些 subSA 的分支作为穿支到达后表面。临床解剖学 32:642-647, 2019. © 2019 Wiley Periodicals, Inc.
