Inflammation of the ulnar nerve. This may occur when the nerve is subjected to pressure. Vulnerable points are at the level of the elbow and where the nerve crosses the wrist on the inner aspect of the hand. The pressure can be caused by friction of local tissues on the nerve, as happens during cycling. Ulnar neuritis is marked by muscular weakness on attempting to spread the fingers, tingling, and numbness in the little finger. See also ulnar compression syndrome.
