Facet Joint Injections/ Medial Branch Blocks

Overview

A Facet Joint Injection is a diagnostic procedure used to determine if pain is due to facet syndrome. It involves using fluoroscopic guidance (X-ray) to pinpoint the specific facet joint(s). Facet joints, located between each vertebra, provide stability and flexibility to the spine. When these joints become inflamed and irritated, it is known as facet syndrome.

The Facet Joint Injection involves a combination of two substances: local anesthetics for numbness and pain relief, and a corticosteroid anti-inflammatory to reduce inflammation. If successful, the procedure confirms that the pain originates from the facet joints, aided by the use of local anesthetics providing feedback. 

Procedure

The procedure begins with the application of a local anesthetic to make it tolerable, followed by the insertion of a needle into the facet joint with fluoroscopic guidance.

Facet joint injections are usually completed within 20 to 30 minutes. After the procedure, patients are observed for about 45 minutes for any potential side effects. These injections can typically be performed up to three times over six months.

What to expect after the Procedure:

Facet Joint Injections are common and have a long history of being performed safely by healthcare professionals. After the procedure, patients may experience soreness around the back or neck for 1 to 2 days. It is recommended to take it easy on the day of the procedure but normal activities can be resumed the next day. The benefits of the procedure are typically felt around the second or third day afterwards.
