Sacroiliac Joint Injection

A sacroiliac (SI) joint injection delivers anti-inflammatory medication directly into the sacroiliac joint, which connects the lower spine to the pelvis. SI joint dysfunction is a common cause of lower back and buttock pain that can radiate down the leg. This procedure serves both diagnostic and therapeutic purposes. If the injection provides relief, it confirms the SI joint as the pain source. The anti-inflammatory medication can reduce swelling and provide lasting relief from SI joint pain.
