Facet Joint Injections

Another type of diagnostic procedure for back pain used by minimally invasive spine specialists is facet joint injections.   The facet joints are the joints that connect the vertebrae in the spine. Each vertebra has two pairs of facet joints. For a more detailed description and anatomical drawing of facet joints, click here.

When a person presents with back pain, a facet joint injection may be one of the diagnostic tests used to help determine the specific cause of the back pain. During this procedure a local anesthetic and sometimes steroids are injected into the facet joint. If the patient experiences near complete or complete pain relief following the spinal injection, the specific facet joint(s) is/are strongly suspected as a source of spinal pain.
