An intra-articular lumbar facet joint block with a local anesthetic and asteroid is a reliable method of diagnosis and therapy for low back pain and/or sciatica caused by lumbar facet arthropathy under fluoroscopy. We injected 40 mg of methylperdnisolone acetate and 1 ml of 0.5% bupivacaine into each lumbar facet joint to 14 patients. The results are as follows: 1) Excellent pain relief in 2 patients (14.29%) 2) Good pain relief in 6 patients (42.85%) 3) Fair pain relief in 4 patients (28.57%) 4) Non effective pain relief in 2 patients (14.29%).
