Signs of Cubital tunnel syndrome

Description

An irritation of the ulnar nerve in the arm. The nerve travels along the inside of the elbow under a bump called the medial epicodyle. Stimulation of this nerve is what causes the arm and hand tingling if the elbow is struck. This is why this part of the elbow is sometimes called the "funny bone". The ulnar nerve in the elbow can become compressed from swelling, arthritis, old fractures, or overuse.

Symptoms

Pain, numbness, and tingling. The numbness and tingling most often occurs in the ring and little fingers. Clumsiness of the arm and pain at the elbow can also occur. The symptoms get worse with bending of the elbow.

Tests

A history and physical exam will be performed. The provider may perform other tests to rule out a thyroid problem or diabetes as the cause of the symptoms. An electromyography (EMG) and/or nerve conduction study (NCS) can confirm the malfunction of the nerve.

Standard Workup

Electomyography (EMG)
Thyroid stimulating hormaone
Chem 12

Treatment

Over the counter non-steroidal medications (ibuprofen/Motrin) an/or acetaminophen/Tylenol can alleviate the pain. A splint to keep the arm straight while sleeping can help as well. Consciously keeping the arm straight during the day is also recommended. If conservative treatment is not effective surgery may be needed to take the pressure off the nerve and resolve the symptoms.
