Tennis Elbow
Examinations and Tests
Your health professional can usually determine if you have tennis elbow by talking to you about the history of your symptoms, daily activities, and past injuries. You'll have a physical examination as well.
X-rays aren't usually needed for diagnosis of tennis elbow but can sometimes rule out other causes of elbow pain, such as arthritis, signs of another type of injury, or a buildup of calcium crystals in a tendon or ligament. X-rays can show unusual bone structure that might cause soft-tissue damage (such as to tendons or muscles), but they don't show soft tissues very clearly. If your elbow pain isn't severe and can't be linked to a specific injury, your health professional may recommend starting treatment without doing X-rays to see whether the problem clears up in a few weeks.
If non-surgical treatment (such as rest, the use of ice and anti-inflammatory drugs, rehabilitation exercises, and changing or stopping certain activities) hasn't helped relieve elbow pain, or if the diagnosis is unclear, other tests may be helpful.
- Magnetic resonance imaging (MRI) can show problems in soft tissues such as tendons and muscles. Access to MRI scanners is not available in all areas. If you need an MRI scan, you may need to travel to a regional centre.
- Arthroscopy allows the health professional to see inside the elbow and get information that can be used together with information from X-rays or a physical examination. (Doctors can surgically treat tennis elbow with arthroscopy.)
- Bone scans are done in rare cases. They can show stress fractures in the bone or certain disease conditions, such as a tumour or infection.
- Arthrogram (joint X-ray) is an imaging technology that involves injecting a material into the joint to enhance its X-ray image. It shows the bones and soft tissues inside the joint, such as the cartilage. Since MRI has become more available, arthrography is used less often to enhance X-rays.
If your health professional suspects nerve damage, electromyogram and nerve conduction tests can check how well your nerves are working.
