![]() There are two purposes for this structure: it is the primary hold by which the clavicle is joined to the scapula and alongside the acromion and coraco-acromial tendon, it shapes the curve over the glenoid. In addition, this structure attaches all the tendons and ligaments together. The muscles that are attached are: Pectoralis Minor, Coracobrachialis, and Biceps Brachii. The suprascapular ligament is right next to the coracoid process. The distances between the coracoid base and the neurovascular structures is like a 90 degree chair. Surgeons refer to this part of the body as the “lighthouse of the shoulder” as it is close to the area where structures of veins and nerves (neurovascular) are bound together. The coracoid process is a snare molded bone design projecting anterolaterally from the unrivaled part of the scapular neck. 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. The horizontal portion appears flattened when viewed from above looking downward its upper surface is convex and irregular, and gives attachment to the pectoralis minor its under surface is smooth its medial and lateral borders are rough the former gives attachment to the pectoralis minor and the latter to the coracoacromial ligament the apex is embraced by the Conjoint tendon of origin of the coracobrachialis and short head of the biceps brachii and gives attachment to the coracoclavicular fascia. The ascending portion, flattened from the frontal aspect backward, presents in front a smooth concave surface, across which the subscapularis passes. As the coracoid process projects laterally, it house underneath it the subcoracoid space. The coracoglenoid notch is an indentation localized between the coracoid process and the glenoid. 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.Īnatomically it is divided into intervals of: base of coracoid process, angle of coracoid process, shaft and the apex of the coracoid process. The coracoid process acts as an attachment and origin for a large number of muscles (attached muscles not labeled here).
