The coracoacromial ligament is a flat triangular band that plays a supportive role for the shoulder joint.
Gross anatomy
- 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
Coracoacromial arch
The coracoacromial arch is formed (anteriorly to posteriorly) by the coracoid process, coracoacromial ligament, and acromion.
Structures located within the coracoacromial arch include:
- subacromial-subdeltoid bursa
- supraspinatus tendon
- long head of biceps tendon
Related pathology
It is thought that decreased space within the coracoacromial arch can result in subacromial impingement.
