Scapula Coracoid Process Anatomy - Everything You Need To Know - Dr. Nabil Ebraheim

Educational video describing the anatomy of the coracoid. The coracoid is a hook shaped bony process that is attached to the neck of the scapula. The coracoid is the light house of the shoulder. The coracoid process is the site of attachment for several structures: 1-Coracoacromial ligament 2-Trapezoid ligament 3-Conoid ligament 4-Acromioclavicular ligament 5-Coracohumeral ligament 6-Coracobrachialis muscles 7-Short head of biceps brachii muscle 8-Pectoralis minor muscle. The subscapularis muscles pass under the coracoid process and inserts into the lesser tuberosity of the humerus. Neurovascular structures enter the upper limb medial to the coracoid process. During treatment of coracoid related injuries, the musculocutaneous nerve and its branches should be identified and protected. The distance between the coracoid and the point of entry of the nerve into the coracobrachialis muscles is between 31-82 mm and the branches of the nerve as close as 17 mm below the coracoid. The surgeon should stay lateral to the coracoid instead of medial in order to avoid these neurovascular structures. The musculocutaneous nerve arises from the lateral cord of the brachial plexus. It is the primary nerve supply to these three muscles: coracobrachialis muscle, brachialis muscle and biceps muscle. Cutaneous innervation: lateral cutaneous nerve of the forearm. The musculocutaneous nerve may become injured during shoulder separation, trauma or surgery. Shoulder separation occurs due to tear of the ligaments that hold the clavicle to the shoulder. When these ligaments are torn it causes at least type III AC joint separation. These ligaments can be torn in distal clavicle fractures rendering the fracture unstable. Coracoid fracture with or without AC joint separation •Type I: fracture proximal to the coracoclavicular ligament usually associated with acromioclavicular separation, clavicular fracture, superior scapular fracture or glenoid fracture. •Type II: fracture distal to the coracoclavicular ligaments. Impingement of the subscapularis tendon between the coracoid process and the lesser tuberosity. Clicking and pain is reproduced with passive shoulder flexion, adduction and internal rotation. The modified Mumford procedure is performed to relieve acromioclavicular joint pain. The Latarjet- Bristow procedure is performed when there is bone loss on the front of the glenoid cavity. The procedure involves transfer of the coracoid with the attached muscles to the area over the glenoid. This replaces the missing bone on the front of the glenoid.
