Nerve Root Disorders
Introduction
Nerve root disorders result in segmental radicular deficits (eg, pain or paresthesias in a dermatomal distribution, weakness of muscles innervated by the root). Diagnosis may require neuroimaging, electrodiagnostic testing, and systemic testing for underlying disorders. Treatment depends on the cause but includes symptomatic relief with nonsteroidal anti-inflammatory drugs, other analgesics, and corticosteroids. (See also Overview of Peripheral Nervous System Disorders .) Nerve root disorders (radiculopathies) are precipitated by acute or chronic pressure on a nerve root in adjacent to the spinal column (see figure Spinal nerve roots ).
