Abstract
Cervical radicular pain is pain along a dermatomal pattern that is caused by the irritation of a nerve root. It is mediated by phospholipase A2, interleukins 1 and 6, TNF-α, and nitric oxide. Cervical radicular pain is often, but not always, associated with nerve root compression, as evidenced by a patient with radicular pain but without evidence of nerve root compression on imaging. Cervical radicular pain is a separate entity from cervical radiculopathy, which involves a sensory or motor deficit from a dysfunctional nerve pathway.
The diagnosis of cervical radicular pain can be accomplished through a multifaceted approach. A thorough history and physical exam that includes provocative tests such as a Spurling test, a shoulder abduction test, and an axial manual traction test can help differentiate cervical radicular pain from discogenic or facetogenic pain. Diagnostic nerve blocks, EMG, and imaging studies can determine the exact nerve root level that is causing pain. Treatment options include conservative medical treatment, physical therapy, cervical epidural steroid injections, or spinal cord stimulation.
