Several muscles responsible for arm movement originate here, including the short head of the biceps brachii and the coracobrachialis, which flexes and adducts the arm. The coracoid process of the scapula is a small but mighty bony projection that forms a central anchor point for the shoulder complex.
Coracoid Process Shoulder Instability Causes and Understanding the Injuries
Clinical Assessment and Imaging When a patient presents with shoulder pain or a history of trauma, clinicians pay close attention to the coracoid region. Standard X-rays, particularly axillary or scapular Y-view projections, provide a two-dimensional assessment of the bone structure.
Unlike other stress fractures, a fracture of the coracoid process can lead to significant instability because it disrupts the critical ligamentous support system connecting the clavicle and scapula. By providing a stable origin for the biceps and coracobrachialis, it allows for powerful flexion and supination of the forearm.

It also forms the base for the coracoacromial ligament, which creates a protective arch over the shoulder joint. Furthermore, the pectoralis minor muscle inserts onto this very point, allowing it to stabilize the scapula against the thoracic wall.
