The coracoacromial ligament, which runs from the coracoid process to the acromion.

It is thick medially, but thinner laterally under the coracoacromial ligament.

Thickening or calcification of the coracoacromial ligament can also cause impingement.

The procedure is done to essentially replace the coracoclavicular ligaments with the coracoacromial ligament.

Detaching the acromial end of the coracoacromial ligament, and possibly shortening it.

The Coracoacromial Ligament is a strong triangular band, extending between the coracoid process and the acromion.

Anatomic Repair, or any repair using tendon allograft without sacrificing the coracoacromial ligament.

By rotating the humerus laterally, this contact is delayed because the greater tubercle is pulled back so that the bicipital groove faces the coracoacromial ligament.

The suprahumeral joint (also known as the subacromial joint) is a physiological joint formed by an articulation of the coracoacromial ligament and the head of the humerus.

However, a progression to a hooked acromion may simply be an adaptation to an already damaged, poorly balanced, rotator cuff that is creating increasing stress on the coracoacromial arch.

In 1972, Charles Neer proposed that impingement was due to the anterior third of the acromion and the coracoacromial ligament and suggested surgery should be focused on these areas.
