b. X-Ray Findings: X-ray examination may reveal changes such as lumbar disk space narrowing and osteophytosis or may be entirely normal. Because x-ray signs are (nonspecific), many clinicians avoid x-ray studies during the initial evaluation. X-rays should be obtained for persons over age 50, in whom (metastatic) tumors are more likely, and those under age 20, in whom symptomatic (congenital) or developmental (anomalies) may be present. For other patients, x-rays may be obtained during subsequent ivsits if symptoms do not resolve within weeks.
