Abstract

Secondary shoulder deformities are frequently observed in patients with obstetric brachial plexus palsy. Muscular imbalance promotes internal rotation, retroversion of the glenoid cavity and, at least, posterior displacement of the humeral head. This dislocation, in addition to the action of the muscle insertions on the coracoid process, causes a elongation of this structure. The coracoid follows the migratory humeral head, overlaping the plane of the glenoid. The reduction of the humeral head may be prevented by the deformity of the coracoid.
