Patients with facet joint arthritis will typically complain of pain and stiffness in the back or neck. The pain is usually described as a dull ache around the affected area. The pain tends not to radiate into the legs or arms. The pain and stiffness is usually worse first thing in the morning and at the end of the day. The pain is exacerbated with physical activity or bending and twisting. Sometimes it can be painful to get up from a seated position.
Like other joints in the body, facet joints are covered by cartilage that allows the bones to move next to each other smoothly without friction. When these areas are inflamed, the bones rub against each other, which causes pain. Arthritis of the facet joints carries multiple names for the same condition, including facet joint arthritis, facet joint arthropathy, and spondylosis.
A Medial Branch Block is a simple office based procedure. It typically takes 10 minutes, and there is no downtime after. It can be done with local anesthesia, or intravenous sedation for comfort if desired. It is generally not painful and well tolerated. During a medial branch block, a small needle is inserted next to the involved facet joint with X-ray guidance (fluoroscopy). After proper placement of the needle is confirmed, a local anesthetic is injected through the needle. This will anesthetize the facet joint and block the pain pathway. This will help identify which facet joint is affected, and results in reduction of pain, increase in function and improved quality of life. Some patients may feel better right away. Patients may return to work the same day or next day.
Medial branch blocks are both diagnostic and therapeutic. Some patients get sustained relief from a block, while others report a few days to a few weeks of relief. If a medial branch block is successful at relieving your pain, you may be a candidate for a Radiofrequency Ablation procedure, which is heat therapy to the facet joint. Radiofrequency Ablation will provide relief for a period of 9 months to 2 years.
Medial branch blocks are generally minimally uncomfortable and very well tolerated. If you have a fear of needles or have severe pain, we do offer IV sedation which is administered by a board certified anesthesiologist. This will help you relax and make the procedure completely painless.
Both procedure are aimed at blocking pain originating from the facet joint. Medial branch blocks tend to be used for diagnosis purposes while facet injections can be used for therapeutic purposes. Both procedures are very similar, and the terms are often used interchangeably.
Side effects generally do not occur. When they do, they tend to be mild and easy to manage. Some possible side effects include temporary facial redness, tenderness at the injection site, mild sleep disturbances, menstrual changes, and elevated blood sugar in diabetics.
Yes, facet injections are FDA approved for the diagnosis and treatment of arthritis mediated facet joint pain.
Face injections are very safe. In expert hands, complications are extremely rare.
Yes, all health insurance plans cover this procedure.
The medial branch block interrupts signals from the the medial branch nerve, which communicates with the facets joints. The anesthetic agent interrupts the pain signals, reduces inflammation, and stops the pain. The purpose of this procedure is to determine if the pain you are experiencing is caused by inflammation of the facet joint. If this procedure leads to a short-term relief of pain of at least 70-80%, the patient is considered an ideal candidate for Radiofrequency Ablation procedure, which would provide long-lasting pain relief.
In younger people, chronic headaches frequently occur secondary to disorders of the cervical spine. These are not true migraines, as general migraine treatments will not abort the headaches. An upper cervical facet injection can help diagnose and treat the source of the headaches. If you have been diagnosed with having chronic migraines and treatment isn’t working, it is possible that the migraine is coming from the cervical facet joints. If a facet injection breaks the pain cycle, the cause of the migraine is likely cervicogenic. Once the diagnosis is established, treatment is usually effective at greatly decreasing the duration and intensity of migraines, and improving quality of life.
