What is the difference between Erb’s palsy and Klumke’s palsy?

The two conditions are similar in that they're both injuries that happen to the brachial plexus. However, the nerve damage in Erb’s palsy happens to the upper nerves and affects your arm. The nerve damage in Klumke’s palsy happens to the lower nerves. The lower brachial plexus nerves affect the muscles in the forearm and the hand. Sometimes the hand will have a claw appearance. Klumke’s palsy is also known as Klumke-Dejerine palsy or paralysis.
