Facet Joint Injections

Patients referred for facet injections most often have degenerative disease of the facet joints.  Facet joints are small stabilizing joints located between and behind adjacent vertebrae.  Even if the facet joint appears radiologically normal, facet injections may still be of use, as radiologically occult synovitis can cause facet pain, particularly in young patients.  Postlaminectomy syndrome, or nonradicular pain occurring after laminectomy, is also an acceptable reason to perform facet injections.  The injection of local anesthetic and steroids into the facet joint is diagnostic and potentially therapeutic. Pain relief following a precise
Intra-articular injection confirms the facet joint as a source f pain.  The injection of steroids provides longer pain relief.  Long-term relief (approximately 6 months) can be obtained in 50-70% of patients.
