The subscapularis is one of the four Rotator Cuff muscles. The four Rotator Cuff muscles are:
- The subscapularis attaches from the subscapular fossa of the scapula to the lesser tubercle of the humerus.
- Medially rotates the arm at the glenohumeral joint
- The Subscapularis is the second “S” of SITS (Supraspinatus, Infraspinatus, Teres minor, Subscapularis), an acronym for the rotator cuff group.
- The subscapularis is located between the scapula and ribcage wall.
- The subscapularis is the only rotator cuff muscle that attaches to the lesser tubercle of the humerus.
