Subacromial, supracoracoid dislocation of the acromioclavicular joint with ipsilateral clavicle fracture: a case report with review of the literature and classification

Abstract

A type VI acromioclavicular joint injury with a supracoracoid location of the distal end of the clavicle (VIa) may be associated with low energy injuries and, in association with a clavicle fracture, can successfully be treated with reduction of the dislocation, fixation of the clavicle, and may not require reconstruction of the acromioclavicular ligaments. An infracoracoid location (VIb) is highly suggestive of a higher energy injury.
