Coracoid process

Coracoid Process

The Coracoid Process (pronunciation: /kɔːrəkɔɪd/ 'kor-uh-koyd') is a small hook-like structure on the lateral edge of the superior anterior part of the Scapula. Pointing horizontally forward, it, together with the Acromion, serves to stabilize the Shoulder joint. It is also known as the processus coracoideus.

Etymology

The term "Coracoid" is derived from the Greek words korax, meaning "raven", and eidos, meaning "shape" or "form". This is due to the beak-like appearance of the coracoid process.

Anatomy

The coracoid process acts as the attachment site for several important muscles and ligaments within the shoulder joint. These include the Coracobrachialis, the Pectoralis minor, and the short head of the Biceps brachii. It also serves as the attachment site for the Coracoacromial, Coracohumeral, and Coracoclavicular ligaments.

Clinical Significance

The coracoid process can be involved in several pathological conditions. These include Coracoid impingement syndrome, Coracoid fracture, and Osteolysis of the coracoid process. It is also a landmark for surgical procedures involving the shoulder joint.
