The coracoid process is an osseous projection that projects from the upper margin of the scapula. This process is directed anterolaterally and positioned directly inferior to the lateral aspect of the clavicle. It connects with the clavicle via the coracoclavicular ligament.
The coracoid process is related to major neurovascular structures such as the brachial plexus, axillary vessels, acromial branch of the thoracoacromial artery, and the sensory branch of the lateral pectoral nerve.
The coracoid process can be palpated through the skin on the lateral aspect of the clavipectoral (deltopectoral) triangle, a depression formed between the clavicle, pectoralis major and deltoid muscle.
The coracoid process serves as the attachment point for several muscles and ligaments.
The muscles include the pectoralis minor muscle, coracobrachialis muscle and short head of biceps brachii muscle. The ligaments that attach to the coracoid process include the coracoclavicular ligament, coraco-acromial ligament, coracohumeral ligament and the glenocoracoid ligament.
