Overview

The purpose of facet joint injection is to ‘numb’ suspected facet joints that are causing painful conditions. In this way the blockade will reduce or eliminates the pain of damaged facet joints by blocking the painful joint that carries the pain signals to the brain. It is performed using local anesthetic to reduce pain with anti-inflammatory steroid added if inflammation of the joint is also a contributing factor. The procedure is very similar to the medical branch block but with a different target of the actual facet joint, rather than the nerve to the joint

Indications

Conditions that are well suited for this treatment are the same ones that can be treated by cervical/lumbar medial branch nerve blocks and rhizotomy. These include neck or back pain that is non radicular, motion sensitive, or associative with facet joint types of pain sources. Cervicalgia, lumbago, degenerative joint pain, spondylosis, neck or back injury and some whiplash injuries are all treated with medial branch blocks and later facet radiofrequency rhyzitomy if indicated.
This procedure is usually indicated for mostly non radicular pain. This can include facet arthropathy, facet joint or disc degeneration and the facet joint syndrome. The same joint is then indicated for the rhyziotomy procedure in order to prolong the pain relief. The area ‘burned’ is usually around 10 mm and the nerve can grow back with pain recurring after a prolonged period of pain relief

What to Expect

Patients usually have injections of the facet joint done on an outpatient basis using fluoroscopy or other image guidance for proper needle placement. The skin will be numbed and the needles placed with sometimes small amounts of contrast used to confirm placement. Then a solution of steroid and/or local anesthetic is injected in small amounts. The effects of the local anesthetic will wear off before the steroid takes full effect such that the immediate effects of the anesthesia may wear off and the pain recur prior to the longer lasting effect of the steroid.

Outcomes

Although pain may increase for the first week after the procedure, the patient usually has full relief from pain within a month. Successful radiofrequency neurotomies can last longer than steroid block with local anesthesia injections. Medial branch nerve blocks are usually done to both treat and diagnosis the cause and effect of the suspected pain condition. For a return of the pain the blocks can be repeated or a rhizotomy can be done on the same nerves.
