Coracohumeral ligament attaches the base of the coracoid process to the greater tubercle. The active and passive soft tissue and bony stabilizers work together to provide glenohumeral stability. Muscles and tendons of the shoulder.

The relative weakness of the capsule itself coupled with the bony structure of the glenohumeral joint means that the rotator cuff muscles are largely. Therefore if someone has an internal rotation contracture they can not abduct 120. Abduction abduction requires external rotation to clear the greater tuberosity from impinging on the acromion.
