Radial Tunnel Release at the Elbow
What it is
Radial tunnel syndrome is caused by increased pressure on the radial nerve, which runs by the bones and muscles of the forearm and elbow.
- Noncancerous fatty tumors (lipomas)
- Bone tumors
- Inflammation of surrounding tissue
Symptoms of radial tunnel syndrome include:
Cutting, piercing, or stabbing pain at the top of the forearm or back of the hand, especially when you try to straighten your wrist and fingers. In contrast to cubital tunnel syndrome and carpal tunnel syndrome, radial tunnel syndrome rarely causes numbness or tingling because the radial nerve principally affects the muscles.
If you have any of these symptoms, your doctor may be able to diagnose radial tunnel syndrome by physical examination alone. He or she also may order a test called electromyography, a nerve conduction study, or both to confirm the diagnosis, identify the area of nerve damage, and stage the severity of the condition.
