Brachial plexus palsy in neonates
Erb palsy is the most common form of brachial plexus palsy in neonates and is caused by disruption of the upper brachial plexus nerves at cervical nerve roots 5 and 6, and possibly 7 (C5–C7). Clinical findings include shoulder muscle paralysis with an asymmetric Moro reflex, an internally rotated upper arm, an extended elbow due to flexor paralysis, a pronated forearm, and a flexed wrist.
