Sacroiliac Joint Injections

What Are Sacroiliac Joint Injections?

A sacroiliac joint injections (SI) are injections of local anesthetic and a steroid medication into the sacroiliac joint. Due to the numbing medicine used during this procedure, you may experience temporary pain relief afterwards that may last several hours. Once the numbing medicine wears off, however, your pain will most likely return. The steroid medication may give longer lasting pain relief and usually begins working after 24-48 hours.

“The SI joints are very small, but they absorb a lot of shock and experience significant wear and tear as we age. An SI joint injection is almost always performed with fluoroscopy (x-ray) image guidance. This allows the doctor to view the Si joints as they guide the needle to it. It is of the utmost importance that the needle is in the appropriate place before the injection occurs, otherwise, your doctor might rules out SI joint dysfunction as the cause of your pain when the injection does not provide relief. The solution injected into the SI joint is a combination of anesthetic and corticosteroid. This will reduce inflammation and provide pain relief for several months. The entire procedure lasts about 20 to 30 minutes, followed by a brief recovery time. Most patients experience pain relief after only one or two injections. It is never recommended that patients receive more than three injections in a six-month time frame.” – Treatingpain Contact your Sound Pain clinic to learn if SI injections are right for you.
