The coracoclavicular joint is a normal variant, where there is a diarthrosis between the conoid tubercle of the clavicle and the superior surface of the horizontal part of the coracoid process of the scapula. The coracoclavicular joint can cause shoulder pain in the setting of arthritis. The images above show radiographs and axial and coronal CTs of a left coracoclavicular joint. The color image is a SPECT/CT fusion of a bone scan obtained for an unrelated condition, showing no evidence of abnormal uptake.
