Coracoid

Coracoid is a small hook-like structure on the lateral edge of the superior anterior part of the scapula. Pointing laterally forward, it, together with the acromion, serves to stabilize the shoulder joint. It is also known as coracoid process, or processus coracoideus.

Anatomy

The coracoid process is a thick curved structure attached to the upper part of the neck of the scapula. It is placed laterally at a higher level than the spine.

Structure

The coracoid process is curved and somewhat resembles a crow's beak. It is directed laterally and forwards, and slightly upwards. Its base is flattened and rough, and it serves for the attachment of the pectoralis minor muscle.

Function

The coracoid process serves as a point of attachment for several structures:

• The pectoralis minor muscle attaches to the coracoid process.
• The coracobrachialis muscle originates from the coracoid process.
• The short head of the biceps brachii also has its origin at the coracoid process.

Clinical significance

Injury to the coracoid process can lead to a variety of problems, including shoulder pain and instability. It can also be involved in certain surgical procedures, such as the Latarjet procedure, which is used to treat recurrent shoulder dislocations.
