What causes Erb's Palsy?

Erb's palsy is generally caused by traction (stretching) of the nerve fibers of the brachial plexus when the head and shoulder are moved in opposite directions .

This type of brachial plexus injury also follows cesarean section deliveries, indicating that it is not simply an indication of a poorly performed delivery.
