  Scapula - Wikipedia, the free encyclopedia
Of the three borders of the scapula, the superior is the shortest and thinnest; it is concave, and extends from the medial angle to the base of the coracoid process.
The coracoid process is a thick curved process attached by a broad base to the upper part of the neck of the scapula; it runs at first upward and medialward; then, becoming smaller, it changes its direction, and projects forward and lateralward.
On the medial part of the root of the coracoid process is a rough impression for the attachment of the conoid ligament; and running from it obliquely forward and lateralward, on to the upper surface of the horizontal portion, is an elevated ridge for the attachment of the trapezoid ligament.

 Case Summary: 5944 from the MedPix™ Medical Image Database and Teaching File
Fractures of the coracoid process relate to a direct injury from a dislocation humeral head, a direct force on the tip of the coracoid itself, or an avulsion owing to traction on the coracoclavicular ligament, the short head of the biceps, or the coracobrachialis.
Isolated fractures of the coracoid process occur as a result of an avulsion injury or in trapshooters related to repetitive stress from the impact of the recoiling rifle.
Neurologic injuries may be a sequela of scapular fracture, particularly one that involves the acromion process or leads to avulsion of the coracoid process.

She had pain on palpation of her right SCJ and coracoid process; the pain was aggravated by shoulder movements, especially horizontal adduction with internal rotation (i.e., the coracoid impingement sign).
Coracoid impingement is characterized by compression of the subscapularis tendon between the coracoid process and the lesser tuberosity of the humerus, resulting in tendinosis and pain in these soft tissues.

 Gray, Henry. 1918. Anatomy of the Human Body. Page 317
The ligaments do not maintain the joint surfaces in apposition, because when they alone remain the humerus can be separated to a considerable extent from the glenoid cavity; their use, therefore, is to limit the amount of movement.
The joint is protected above by an arch, formed by the coracoid process, the acromion, and the coracoacromial ligament.
The articular cartilage on the head of the humerus is thicker at the center than at the circumference, the reverse being the case with the articular cartilage of the glenoid cavity.

 PART III
The acromioclavicular joint itself is a true diarthrosis; the articular surfaces of the acromion process and the outer end of the clavicle, which are separated by a joint cavity, are surrounded by a capsule which is reinforced by ligaments.
In unreduced dislocations of the acromioclavicular joint, the deformity was maintained by three factors, (1) gravity, (2) the pull of the trapezius on the distal end of the clavicle, and (3) the absence of counterpull by the aponeurosis of the anterior portion of the deltoid.

Furthermore in contrast to soft tissue procedures, coracoid transfer procedures are extremely difficult and hazardous to revise: the subscapularis, musculocutaneous and axillary nerves are scarred in abnormal positions; the subscapularis muscle is scarred and tethered; and the axillary artery may be displaced in scar tissue.
The Latarjet procedure, (Latarjet, 1958; Latarjet, 1968; Pascoet et al, 1975) described in 1954, involves the transfer of a larger portion of the coracoid process than used with the Bristow procedure with the biceps and coracobrachialis tendons to the anteroinferior aspect of the neck of the scapula.
Instead of the raw cut surface of the tip of the coracoid process being attached to the scapula as is done in the Bristow-Helfet procedure, the coracoid is laid flat on the neck of the scapula and held in place with one or two screws.
