Ulnar Nerve Palsy

The ulnar nerve travels down the arm from the shoulder to the hand. It controls movement and feeling in the wrist and hand. Damage to this nerve can cause a condition called ulnar nerve palsy.

A common cause of ulnar nerve palsy is leaning on the elbow for long periods of time. Injury to the arm or elbow, such as a fracture, can also damage the ulnar nerve.

Symptoms of ulnar nerve palsy include:

• Numbness, tingling, or burning (often described as pins and needles)

• Pain

• Weakness or muscle shrinking in the hand and fingers

The treatment depends on the cause of the nerve damage. In some cases, the problem will go away on its own once pressure to the nerve is relieved. Certain tests may be done to help determine the injury and extent of damage. These include nerve conduction studies (NCS) and electromyography (EMG). Splinting the wrist or elbow to limit movement may help with healing. If the problem is due to trauma or injury, physical therapy may be prescribed. Corticosteroid injections into the area may reduce swelling and pressure on the nerve. Surgery to repair the nerve may be needed for chronic symptoms that don't respond to simpler treatments.
