Sacroiliac Joint Injections - Trinity Surgery Center-1Your sacroiliac joints connect your spine to your pelvic bones, and they absorb the force of your upper body. If they become irritated, chronic pain can result. Sacroiliac joint pain is a common cause of back pain in the lower back, groin, buttocks, and legs.

How it Works

Sacroiliac joint injections are made up of a local anesthetic and steroid medication. When injected into the joint, the medication reduces inflammation of the joint for pain relief. The injections are also used diagnostically to confirm that an irritated or damaged sacroiliac joint is the cause of symptoms.

What to Expect
