Radial Tunnel Syndrome

Radial tunnel syndrome is caused by compression of the radial nerve near the elbow and can cause pain near the outside of the elbow (lateral epicondyle) and back of the forearm (dorsal forearm).

What is the condition?
Radial tunnel syndrome is caused by compression of the radial nerve near the elbow and can cause pain near the outside of the elbow (lateral epicondyle) and back of the forearm (dorsal forearm).  Your provider will differentiate this from lateral epicondylitis (tennis elbow), which also causes symptoms in this region. The pain of radial tunnel syndrome is often worse with rotation of the forearm and can cause a cramping, aching pain in the forearm. 

How is radial tunnel syndrome diagnosed?
There are no perfect diagnostic tests to confirm the diagnosis, which is often made based on history and clinical examination.

How is radial tunnel syndrome treated?
Treatment begins with occupational and physical therapy and, if the pain persists, may include surgical nerve decompression in an attempt to improve the related discomfort.
