Sacroiliac Joint Injection FAQ
The sacroiliac joints are located at the bottom of the spine on both the left and right sides where your hip bones (ilium) are attached to the sacrum. When the sacroiliac joints become inflamed or injured this may lead to sacroiliac joint dysfunction characterized by pain in the lower back, buttocks, groin, and legs.
Sacroiliac joint injections treat pain in the lower back, buttocks, groin, and legs caused by sacroiliac joint dysfunction -- inflammation or injury to the sacroiliac joints.
Sacroiliac joint injections are office-based minimally invasive procedures that take approximately twenty minutes to perform and are typically done under local anesthesia. This procedure is done under X-Ray guidance. A potent long-lasting anti-inflammatory pain medication (steroid) is injected directly into the sacroiliac joint decreasing inflammation, and providing pain relief for several months. A local anesthetic may also be used.
