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.
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.
The coracoclavicular joint represents a true synovial articulation between the conoid tubercle of the clavicle and the superior surface of coracoid process of the scapula. This accessory articulation may be found either unilaterally or bilaterally.
Osteoarthritis may develop in this joint and be a source of shoulder pain 2,4.
