Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Cervical radiculopathy is caused by compression of a nerve root by a laterally bulging or herniated intervertebral disk, osteoarthritis, or degenerative spondylosis. Pain results from injury to the nerve roots and nerves innervating the dura, ligaments, facet joints, and bone. Common clinical features include pain, paresthesia, and root signs (sensory loss, lower motor neuron muscle weakness, impaired reflexes, and trophic changes). Frequently, there is numbness and tingling following a dermatomal distribution. Magnetic resonance imaging (MRI) is the test of choice to distinguish cervical radiculopathy from disk and bone disease. Electromyelography studies may also be helpful in ruling out other disease processes. Trauma, myelopathy, plexopathy, neurofibromatosis, metastatic tumor infiltration of nerve roots, neoplasm, shingles, and central cord syndrome should be considered in the differential.
