A fracture which starts medial to the CC ligaments and runs superio laterally into the AC joint is classified as an AO/OTA 15.3B(c) fracture.
Definition: Distal fractures of the clavicle involve the clavicle lateral to a perpendicular line to the medial cortex of the coracoid base.
Displaced fractures demonstrate swelling, bruising, and a deformity with apparent superior migration of the shaft fragment as the shoulder sags downwards and medially.
