Abstract: Acromioclavicular disjunction is a frequent traumatic lesion, but one that often goes unnoticed. Its association with coracoid process fracture / or a rupture of the coraco-clavicular ligaments is infrequent or even exceptional.
We report the case of a young man polytraumatized by traffic road and who also presented: acromioclavicular disjunction, a coracoid process fracture, and a rupture of the coraco-clavicular ligaments. The surgical treatment carried out was an acromioclavicular fixation by a screwing associated with dynamic muscle transfer (Dewar Barrington technique). After 8 months follow-up the functional result was satisfactory. The aim was to highlight this rare clinical entity and to discuss its therapeutic modalities and prognostic.
