Facet Joint Injection


What is a Facet Joint Injection?

A Facet Joint Injection is an injection of long lasting steroid into the facet joint. Facet joints are flat surfaces that touch where the vertebrae fit together. These joints are used in twisting, turning, and bending.


What is the purpose of the injection?

The steroid injected reduces the inflammation and/or swelling of the joint. The injection may not stop all pain but it may reduce inflammation and swelling. By decreasing pain, you will be able to actively participate in physical therapy as prescribed which is essential for optimal benefit.

What is injected? 

The injection consists of a mixture of a local anesthetic and steroid.


Will the injection hurt? 

The procedure is with x-ray guidance and involves inserting a needle through skin and deeper tissues. There is some discomfort involved. However, the skin and deeper tissues are numbed with a local anesthetic. Most of the patients also receive intravenous sedation which makes the procedure easy to tolerate.


Will I need more than one? 

Pain relief should last for weeks to months. If the pain returns, you may need a repeat injection.


What are the risks and side effects? 


With any procedure there are risks, side effects, and possibility of complications.  The most common side effect is pain, which is temporary. Other risks include infection, bleeding, prolonged pain,  nerve damage (very rare).


What should I expect after the injection? 


After the injection, you may feel that your mobility has improved which is a result of the local anesthetic. After the anesthetic wears off, you may have an increase in pain for the next 2-5 days then you should begin to see an improvement. This pain is due to the process of the needle insertion as well as the initial irritation from the steroid itself.  Use of ice is encouraged.
