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]
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.
Coracoid of left scapula. The operation is called the Latarjet surgery. The procedure involves transfer of the coracoid with its attached muscles to the deficient area over the front of the glenoid. This replaces the missing bone and the transferred muscle also acts as an additional muscular strut preventing further dislocations.
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).
The acromion of the scapula is connected to the clavicle by the superior acromioclavicular ligament. The coracoclavicular ligaments connect the clavicle to the coracoid process. The two ligaments that form the coracoclavicular ligaments are the trapezoid and conoid ligaments. These three ligaments add support to the shoulder joint. [citation ...
Associated bony lesions or fractures may coexist in the glenoid such as the bony Bankart lesion. In such scenarios, surgical repair may include bony augmentation, a common example of which is the Latarjet procedure. Additional lesions such as a Bankart, SLAP tear, or biceps injury may also be present. [7]
A fracture in this area is most likely to cause damage to the axillary nerve and posterior circumflex humeral artery. Damage to the axillary nerve affects function of the teres minor and deltoid muscles, resulting in loss of abduction of arm (from 15-90 degrees), weak flexion, extension, and rotation of shoulder as well as loss of sensation of ...
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]
