Radiculopathy and Plexopathy

Disorders of the nerve roots and neural plexi present with pain, numbness, or weakness in the neck, back, or extremities. Although the history and physical examination provide essential diagnostic information, imaging and electrodiagnostic studies may further aid in localizing and characterizing the underlying lesion. Causes of radiculopathy include intervertebral disc herniation, spondylosis, spinal synovial cysts, infection, metastatic disease, hematoma, or infiltrative disease. The brachial and lumbosacral plexi are susceptible to trauma, structural anomalies, neoplastic infiltration, and inflammatory processes. Management of these disorders is directed at treating the underlying cause, alleviating pain, and focused physical rehabilitation.
