The lumbar facet joint has long been considered a significant source of low back pain (LBP). A common method for diagnosing lumbar pain are diagnostic blocks where an anesthetizing agent is injected to determine if pain is relieved. Facet blocks with anesthetic and cortisone, and even facet denervation procedures, have been recommended as treatment for patients with LBP. So the evaluation of outcome and patient selection are important in the treatment of low back pain. We present clinical experiences on 116 patients with lumbar facet joint syndrome and review the relevant literature.
