What Is Ulnar Neuropathy?

Ulnar neuropathy is a condition that develops when the ulnar nerve, which runs down the arm and into the hand, becomes damaged and inflamed. The disorder is also referred to as cubital tunnel syndrome, and bicyclists refer to it as handlebar palsy.

Symptoms

• Symptoms of ulnar neuropathy can include numbness, pain and tingling that may be felt in the ring and little fingers, elbow and forearm. Weakness of the hand may also develop.

Causes

• Ulnar neuropathy often develops after the ulnar nerve is damaged by repetitive wrist movements or an elbow injury, according to the University of Michigan Health System. The condition is common in baseball players, bicyclists and typists.

Diagnosis

• Nerve conduction studies, which use an electrical current to measure the speed at which nerves conduct impulses, and electromyography, which involves inserting small needles into a muscle to analyze its electrical activity, may be used to diagnose ulnar neuropathy.

Treatment

• Ulnar neuropathy may be treated with wrist or elbow splinting and physical therapy. Keeping pressure off of the elbow may also improve symptoms. Severe cases may require surgery, according to Merck.

Prevention

• Avoid placing constant pressure on your elbow, and minimize repetitive wrist movements to prevent the disorder.
