Shoulder pain on abduction and internal rotation.

Patient Data

Age: 60
Gender: Female

Narrowed coraco-humeral distance, mild subscapularis and severe supraspinatus tendinosis. Fliud-filled subcoracoid bursa.

Case Discussion

The normal average distance between the coracoid process and the humeral head is 9-11 mm 1. A distance of 5 mm or less is highly associated with subscapularis tendinosis and tendon tears 2. The distance is better assessed in internal rotation, which isn't routine practice.
