Obstetric brachial plexus injury complicated with glenohumeral dysplasia

Abstract

Brachial plexus injury is the most common cause of plegic arm in neonates. Detection of nerve root avulsions and intraspinal nerve lesions is most valuable for treatment strategy. Magnetic resonance imaging (MRI) is the modality of choice for imaging the brachial plexus in infants as it allows visualization and localization of different types of nerve lesions in a noninvasive way and without radiation exposure. Conventional radiography of the shoulder is of interest in follow-up to assess osseous deformities of the glenoid fossa and humeral head. We report a case of obstetric brachial plexus injury complicated with glenohumeral shoulder deformity in a 3-year-old girl.
