Abstract
Fluoroscopically controlled intra-articular facet joint block is a reliable method of diagnosing low back pain and sciatica caused by lumbar facet arthropathy. Of 20 patients, 13 had complete and immediate pain relief, confirming the diagnosis. Six patients were free of pain for more than 6 mo. following a single facet joint block with injection of a local anesthetic and corticosteroid suspension. Preliminary findings suggest that computed tomography has an important role in diagnosing symptomatic facet arthropathy.
