Coronal PD fat sat
Separation of the AC joint with superior displacement of the clavicle relative to the acromion. Disruption of the AC joint capsule and the AC ligaments. In addition, there is a total disruption of the CC ligaments.
Case Discussion
The findings are consistent with a type III acromion-clavicular dislocation in the Rockwood classification, where the clavicle is elevated above the superior border of the acromion but the coracoclavicular distance is less than twice normal (i.e. <25 mm). Both the AC and CC ligaments present total disruption.
