Coracoclavicular joint with shoulder pain

Abstract

A 53-year old man presented with chronic left shoulder pain, unresponsive to anti-inflammatory treatment. There was no history of injury or chronic overuse. Radiography showed degenerative changes of the acromioclavicular joint, an acromion type 1, and the presence of coracoclavicular joint. CT scan confirmed the presence of a joint between the clavicle and the coracoid process with degenerative changes (Fig. A, B).
