The coracoclavicular (CC) distance is an indicator of the integrity of the coracoclavicular (CC) ligament.

Radiographic featuresMeasurement

The CC distance is assessed on a frontal radiography of the shoulder or clavicle or the coronal projection or a CT or MRI as the distance between the superior cortex of the coracoid process and the undersurface of the clavicle where the CC ligaments insert.

Interpretation

A normal CC distance is between 11-13 mm and there should be no greater than 5 mm difference between the left and right sides ¹.

It is relevant for the determination of the ~~grade~~Rockwood type of AC joint injury.
