Fractures of the coracoid process arf rare and those associated with a complete acromioclavicular separation and clavicular shaft fracture are even more rare. The mechanism of injury may be by direct trauma or by avulsion when there is sudden and violent contraction of the biceps, corachobrachilalis, and pectoralis minor muscle.

The fracture occurs most commonly through the base. Conservative treatment can produce good result. Unusually open reduction is indicated for marked displacement associating acromioclavicular dissociation or compiession of the brahial plexus. The authors report 2 cases of coracoid process fracture. one case combined with acromioclavicular separation and the other with fracture of clavicular mid shaft.
