What is a lumbar facet joint injection?
The lumbar facet joints are small joints located along each side of the lumbar spine. They help provide support to the back of the spine. These joints can become arthritic and painful for a number of reasons. The joints cause back pain that radiates into the buttock and hips. Injection of local anesthetic and steroid into the joint can help relieve pain and treat inflammation of the lumbar facet joint.
