Cervical radiculopathy refers to injury or compression to the cervical nerve root(s) that results in pain and/or numbness distribution of the nerve. Clinically, patients present with neck and/or arm pain and numbness in the concordant dermatomes or myotomes. In the absence of “red flag” symptoms, treatment consists of conservative, medical, and interventional therapies. This review covers the epidemiology and etiology, pathophysiology and pathogenesis, diagnosis, treatment, and prognosis of cervical radiculopathy. The figure shows the cervical vertebrae and associated neural elements. Tables list the “red flag” symptoms suggesting prompt evaluation, clinical correlates among patients with cervical radiculopathy, and the differential diagnosis of cervical radiculopathy.
This review contains 1 figure, 3 tables, and 33 references.
