Sacroiliac Joint Injections​

The sacroiliac joint (SI joint) is the joint between the sacrum and the ilium. Sacroiliitis is irritation/inflammation of the SI joint. This pain causes low back/buttocks pain that can refer into the groin or back of the leg. ​

A sacroiliac joint injection is an injection performed under fluoroscopic guidance (X-ray imaging). A small needle is inserted into the joint where both steroid and local anesthetic are injected. The local anesthetic is diagnostic (lets us know if the joint is what’s causing your pain) and the steroid works to reduce the inflammation and irritation.​
