The coracoclavicular joint is a normal variant of the pectoral girdle, where the conoid tubercle of the clavicle appears enlarged or elongated, with a flattened inferior surface where it approximates the coracoid process of the scapula to form an articulation.

Epidemiology

More common in Asians than in Africans or Europeans with a prevalence of ~10% (range 0.5-20%) with equal male:female distribution^1-2,4.

Gross anatomy

The ~~coracoclavicular~~ coracoclavicular joint ~~represents a~~ represents a true synovial articulation between the conoid tubercle of the ~~clavicle~~ clavicle and the superior surface of ~~coracoid~~ coracoid process of of the scapula. This accessory articulation may be found ~~either~~ either unilaterally or bilaterally.

Related pathology

Osteoarthritis may develop in this joint and be a source of shoulder pain ^2,4.
