Sacroiliac Joint Injection

An inflamed sacroiliac joint can cause back and leg pain. The sacroiliac joint is located in the lower back. The sacroiliac joint is commonly a pain generator in patients who have had previous back surgery. Sacroiliac joint dysfunction can also be caused when a patients foot and leg is “jammed” into the pelvis during a motor vehicle accident.

Injection of steroid and local anesthetic into the joint can provide significant pain relief. A long lasting steroid (cortisone) is injected into the sacroiliac joint to help decrease inflammation and/or swelling of tissue in the joint space. The procedure involves inserting a needle through the skin and deeper tissues into the SI joint. More than one injection may be needed for symptom relief.
