    Ulnar nerve damage
   
Ulnar nerve damage

The ulnar nerve originates from the brachial plexus and travels down arm. The nerve is commonly injured at the elbow because of elbow fracture or dislocation. The ulnar nerve is near the surface of the body where it crosses the elbow, so prolonged pressure on the elbow or entrapment of the nerve may cause damage. Damage to the ulnar nerve may involve impaired movement or sensation in the wrist and hand.
