Erb-Duchenne palsy is a type of brachial plexus injury that affects the nerves that control the arm and shoulder. C5-C6 damage causes loss of sensation on the lateral aspect of the arm, and paralysis of the muscles of the shoulder and arm supplied by C5-C6 (deltoid, infraspinatus, biceps, brachialis). This causes an adducted shoulder, medially rotated arm, extended and pronated elbow with a flexed wrist held in a 'waiter's tip' position.
