Lumbar Facet Block

What should I expect from this procedure?

A lumbar facet joint block is an injection of local anesthetic into one or more of the small joints located along the side of each vertebrae in the lower back. Multiple injections may be performed, depending upon how many joints are involved. Facet joint blocks are typically requested for patients who have back pain primarily as a result of arthritic changes in the facet joints or for patients who have lower back pain. A facet joint block may be diagnostic, to determine the source of the pain, or therapeutic, to relieve the pain.

How quickly can I expect pain relief?

You might feel some initial pain relief from the local anesthetic immediately following the procedure. Your pain may return and then be relieved again when the steroid begins to work. Do not be alarmed if your relief is temporary, as it can take 12 hours to 2 days for the steroid to work and relieve your pain.

How should I prepare for the procedure?

You should eat no solid food or fluids after midnight prior to the procedure unless directed otherwise. You may take your regular medications with a small amount of water. If you are taking any blood thinners such as Coumadin, Warfarin, Plavix, or any others, these medications must be discontinued well before the procedure. The Advanced Pain Institute will direct you when to stop taking these medications.

What happens during and after the procedure?

During the procedure, a thin needle will be inserted near your lumbar spine to the affected facet joint. The doctor will use an x-ray with dye or a computerized tomography (CT) scan to help guide the needle. He will place the needle tip inside or just outside the facet joint. When the needle is placed properly, the doctor will inject medicines like steroids for inflammation and anesthesia for immediate pain relief.
You may be taken to a recovery room to rest following the procedure. Once the Advanced Pain Institute staff determines you are ok, you will be released.

Will my insurance cover the procedure?

Most insurance companies currently cover lumbar facet blocks. They are covered by Medicare and other government funded insurance plans. However, coverage may vary depending on your specific plan and policy.

What possible side effects might I see?

Possible side effects may include drowsiness, temporary numbness, weakness and soreness.

What should I do if any problems develop after I leave the hospital?

If you experience severe pain, new numbness or weakness of your legs, a temperature of 100.5° or greater, or signs of infection in the area of the injection (redness, swelling, heat, discharge), please call the Advanced Pain Institute immediately (626) 445-2371.

What post procedure instructions are recommended?

You should rest for a few hours following the procedure, and use assistance if needed. You may resume light activity soon after the procedure, and resume your regular diet. Do not drive or operate machinery for at least 12 hours following the procedure.
