Causes of Distal Clavicle Osteolysis and Treatment Options
Distal clavicle osteolysis is shoulder joint pain at the end of the collarbone that is the result of bone disintegration and damage. The most common symptom is a sharp or aching pain at the junction of the acromioclavicular joint (AC joint) and collarbone. While the pain is usually felt during activity, there may also be a persistent tenderness around the joint during non-activity. Inflammation and swelling are also common manifestations.
