The coracoid process acts as an attachment and origin for a large number of muscles (attached muscles not labeled here). The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; [2] it runs at first upward and medially; then, becoming smaller, it changes its direction, and projects forward and laterally.
A coracoid [a] is a paired bone which is part of the shoulder assembly in all vertebrates except therian mammals (marsupials and placentals). In therian mammals (including humans ), a coracoid process is present as part of the scapula , but this is not homologous with the coracoid bone of most other vertebrates.
The coracoacromial ligament is a strong triangular ligament between the coracoid process and the acromion. It protects the head of the humerus . Its acromial attachment may be repositioned to the clavicle during reconstructive surgery of the acromioclavicular joint (shoulder joint).
In human anatomy, the acromion (from Greek: akros, "highest", ōmos, "shoulder", pl.: acromia) is a bony process on the scapula (shoulder blade). Together with the coracoid process, it extends laterally over the shoulder joint. The acromion is a continuation of the scapular spine, and hooks over anteriorly.
The coracoclavicular ligament connects the clavicle to the coracoid process of the scapula. [1] It is not part of the acromioclavicular joint articulation, but is usually described with it, since it keeps the clavicle in contact with the acromion. It consists of two fasciculi, the trapezoid ligament in front, and the conoid ligament behind. [2]
The Latarjet procedure involves the removal and transfer of a section of the coracoid process and its attached muscles to the front of the glenoid. This placement of the coracoid acts as a bone block which, combined with the transferred muscles acting as a strut, prevents further dislocation of the joint. [3]
Runs laterally over the coracoid process and under the deltoideus, to which it gives branches; it then pierces that muscle and ends on the acromion in an arterial network formed by branches from the transverse scapular (a.k.a. suprascapular), thoracoacromial, and posterior humeral circumflex arteries. Clavicular branch
On imaging, it is defined by the coracoid process at its base, the supraspinatus tendon superiorly and the subscapularis tendon inferiorly. Changes of adhesive capsulitis can be seen at this interval as edema and fibrosis. Pathology at the interval is also associated with glenohumeral and biceps instability. [16]
