How Is Cubital Tunnel Syndrome Diagnosed?

Following a full medical history and physical exam, the physician will order some of the following tests and exams to determine whether the patient has cubital tunnel syndrome, which occurs when the ulnar nerve on the inside of the elbow becomes inflamed, swollen, or irritated:

  • nerve conduction test: it measures how fast signals travel down the nerve to find a compression or constriction of the nerve
  • electromyogram: it is used to observe nerve and muscle function and may also be used to test the forearm muscles controlled by the ulnar nerve – if the muscles do not work properly, this may be a sign that there is a problem with the ulnar nerve
  • X-ray: it is recommended for patients who might have arthritis or bone spurs in their elbow, as it allows the physician and surgeon to look at these growths if they are present

Only after the patient undergoes all the ordered tests and exams will the orthopedic surgeon be able to make a decision regarding which procedure is the best to cure their cubital tunnel syndrome. Additional tests and exams may be necessary, depending on the complexity of the case.
