Sacroiliac Joint Injection

The sacroiliac joint, or SI joint, is the joint in the pelvis that connects the sacrum and iliac bones to form the pelvis. This joint allows mobility of the pelvis and stretches for women during labor. The SI joint itself usually does not incur much movement; so, sacroiliac joint pain may be caused by an underlying condition that interrupts or prohibits joint movement. Hip, knee or ankle pain that changes the patient’s gait, or walking manner, may cause SI joint pain. Other problems causing or contributing to sacroiliac joint pain include systemic disorders such as arthritis and ankylosing spondylitis. Sacroiliac pain is often confused with hip pain and lower back pain, as well as buttock pain. SI joint pain may be responsible for up to 15% of lower back pain.

How is a Sacroiliac Joint Injection Performed?

First, the sacroiliac joint is located by fluoroscopy, which is using live x-ray guidance. A local anesthetic numbs the skin and the tissue down to the surface of the sacroiliac joint. Then, a needle is inserted through the anesthetized area. A solution of steroid and anesthetics is injected into the joint, immersing the affected area and providing pain relief.

What should be expected?

The steroid medication can reduce swelling and inflammation in the joint. Other treatment options for management may include non-surgical therapies such as chiropractic manipulation, physical therapy and aquatic therapy.
