Abstract

The acromioclavicular separation (AC separation) is a common injury, which is often accompanied by the rupture of the coracoclavicular ligament (CC ligament) in severe occasions. In rare forms of AC separation, the fracture of the coracoid process would occur rather than the rupture of the CC ligament. Only 31 cases of such injury have been reported in the English literature. We present 2 additional cases with literature review. The fracture of the coracoid process is not readily seen on anteroposterior shoulder radiograms. Severe AC separation without widening of CC distance on anteroposterior shoulder radiogram heralds the fracture of the coracoid process.
