The coracoacromial ligament is a flat triangular band that plays a supportive role for the shoulder joint.
- originates from the medial border of the acromion
- attaches to the lateral border of the coracoid process
- overlies the subacromial bursa
- indirectly supports the head of the humerus
The coracoacromial arch is formed (anteriorly to posteriorly) by the coracoid process, coracoacromial ligament, and acromion.
Structures located within the coracoacromial arch include:
It is thought that decreased space within the coracoacromial arch can result in subacromial impingement.
