Coracoid process

Coracoid Process 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 called the beak of the scapula.

Anatomy

The coracoid process is a thick curved structure attached to the upper part of the neck of the Scapula. This process is the lateral part of the scapula, and projects anteriorly and laterally into the shoulder joint. The coracoid process has a broad base, which gradually tapers to an apex as it curves forward and lateralward.

Function

The coracoid process serves as a point of attachment for several important muscles and ligaments of the shoulder joint. These include:

• Coracobrachialis: This muscle originates from the coracoid process.
• Short head of the biceps: This muscle also has its origin point at the coracoid process.
• Pectoralis minor: This muscle attaches to the coracoid process, providing stability to the scapula.

Clinical Significance

The coracoid process can be involved in several pathological conditions:

• Fractures: Although rare, fractures of the coracoid process can occur, often as a result of direct trauma.
• Osteolysis: This is a pathological process that involves the dissolution of bone, including the coracoid process.
• Impingement syndrome: This condition can occur when the coracoid process comes into contact with the subscapularis tendon.
