The suprascapular artery supplies the supra- and infraspinatus muscles and travels with the suprascapular nerve. It is a direct branch from the subclavian artery (12%), the thyrocervical trunk (27%) or the internal thoracic artery (11%).
What nerve supplies the subscapularis?
The subscapularis is innervated by both the upper subscapular nerve (USN) and lower subscapular nerve (LSN). Both the USN and LSN arise from the posterior cord of the brachial plexus.
What arteries supply the rotator cuff muscles?
The major arterial supply to the rotator cuff is derived from the ascending branch of the anterior humeral circumflex artery, the acromial branch of the thoracoacromial artery, as well as the suprascapular and posterior humeral circumflex arteries.
