Answer

The rotator cuff contacts the coracoacromial arch undersurface in the normal shoulder.

The coracohumeral ligament is often resected in order to decompress the supraspinatus outlet, which can lead to increased superior translation of the humeral head, particularly in the young athlete.

Rotator cuff abrasions and fiber failure occur when repeated and excessive compression from humeral head migration is present.

This occurs secondary to underlying muscular imbalance and loss of rotator cuff depressor effects.
