Coracoclavicular distance
Updates to Article Attributes
Body
was changed:
The coracoclavicular (CC) distance is an indicator of the integrity of the coracoclavicular (CC) ligament.
Measurement
The CCcoracoclavicular distance is assessed on frontal radiography of the shoulder or clavicle or the coronal projection of a CT or MRI as the distance between the superior cortex of the coracoid process and the undersurface of the clavicle where the CCcoracoclavicular ligaments insert.
Interpretation
A normal CCcoracoclavicular 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 Rockwood type of acromioclavicular joint injury.
