Facet Joint Injections
What is a facet joint?
Facet joints join the vertebrae together in the spine. These joints are often compressed and irritated due to aging or trauma.
Purpose of a facet joint injection
A facet joint injection is a diagnostic procedure which involves injecting anesthetic and cortisone into the joint. These injections are done to confirm the joint is the source of your pain. In addition to providing diagnostic information, some patients (10 — 20%) will obtain long term relief over 3 months. If the procedure provides significant relief for the duration of the anesthetic or cortisone, patients will be considered a candidate for Medial Branch Block and potentially RF Neurotomy.
Facet joint injection procedure
The procedure will take approximately 30 minutes, depending on the number of facets to be injected (two facet joints are normally injected per visit). While lying on your stomach, the back or side of the spina area will be cleansed with an antiseptic solution, and a local anesthetic administered. Using fluoroscopy, the radiologist will direct a small needle into the appropriate spinal facet joint. A small amount of X-ray contrast will be injected to assure proper placement of the needle. A local anesthetic and steroid will be injected into the joint.
Does Health Care or Insurance cover this procedure?
Alberta Health Care will cover the cost involved with this procedure. The Workers Compensation Board will also cover this procedure if you have a claim number.
Are there risks?
Generally this procedure is safe; however with any procedure there are risks, side effects and the possibility of complications. You may feel some pressure or other mild discomfort during the injection. Occasionally you may experience local bruising. Rarely, the local anesthetic may spread to nearby nerves and cause temporary weakness and numbness. On rare occasions, a patient will have an adverse reaction to contrast material used.
If you feel you may be a candidate for this procedure, speak with your family physician about a referral or arrange for a consultation with an Evidence Sport and Spine physiotherapist at the Advanced Spinal Care Centre for an evaluation.
