Lateral, displaced fracture with CC disrupted, extraarticular clavicle fracture

A fracture which starts lateral to the CC ligaments and runs superiorly and does not affect the AC joint surface is classified as an AO/OTA 15.3A(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.
