The ulnar nerve transmits impulses to muscles in the forearm and hand. This nerve is responsible for the proper sensing of touch, texture, and temperature throughout the fourth and fifth digits of the hand, the palm and the underside of the forearm. Ulnar neuropathy is an inflammation or compression of the ulnar nerve, resulting in numbness, tingling and pain in the outer side of the arm and hand near the little finger. In more advanced cases, weakness and loss of muscle in the hand may also occur. Elbow pain is very frequent and many may experience a sharp shooting pain down the arm.

After a thorough examination including evaluation of strength and sensation, electromyography and nerve conduction studies may be ordered to help confirm the diagnosis of ulnar neuropathy and to determine its severity.

After undergoing testing, treatment typically consists of conservative management including avoidance of postures that may injure the nerve and wearing a protective pad on the elbow. If symptoms persist, surgical treatment can be pursued.
