Sacroiliac (SI) joints are located where your spine joins with your pelvis. Although the joints are small, they absorb the force of your upper body before your legs and hips. Inflammation of the joints can cause chronic pain. An SI joint injection uses fluoroscopy imaging to deliver cortisone to the joints and in turn reduce inflammation. The procedure takes 20 to 30 minutes.
What conditions does it treat?
What can I expect afterward?
You may experience weakness in your limbs from the anesthetic for a few hours and pain at the injection site for a few days. Pain relief from the corticosteroid portion of the injection will occur after a few days, and last for several months. If necessary, you can have up to three SI joint injections in six months, performed two to three weeks apart.
