The subscapular artery arises from the axillary artery, at the level of the distal edge of the subscapularis muscle. In about 20% of individuals, the posterior circumflex humeral and subscapular arteries originate from a common trunk (Tubbs, Shoja and Loukas, 2016).


The subscapular artery is the largest branch of the axillary artery and has a short inferior course of approximately 4 cm.


The terminal branches of the subscapular artery are the circumflex scapular and thoracodorsal arteries.

Supplied Structures

The subscapular artery supplies the subscapularis muscles and the scapular region via its terminal branches.
