Dislocated (upward) AC joint with a displaced fracture of the coracoid process at its base. Note that the coraco-clavicular ligament is intact (arrow).
Case Discussion
The coraco-clavicular ligament remains intact thus is stronger than the bone of the coracoid causing it to be uvulsed. This is unusual in AC dislocation, where the ligament usually ruptures first
