what does the subscapularis
The subscapularis is a large triangular muscle which fills the subscapular fossa and inserts into the lesser tubercle of the humerus and the front of the capsule of the shoulder-joint.o and Burkhart even tagged the subscapularis tendon hypercritically as the forgotten tendon. That arises by the gap of the described tear prevalence in cadavers between 29 and 37% and in clinical studies around 27%.
