Sacroiliac Joint Injection


What are the sacroiliac joints?

The sacroiliac joints (SI) are paired structures (on the right and left) that connect the spine to the pelvis and allow for motion. The SI joint, like other joints in the body, is surrounded by a capsule that contains lubricating fluid. SI joint motion allows us to walk upright, to lift, and to carry. Occasionally, the SI joint motion unit can become dysfunctional (for a variety of reasons), causing pain.
