The sacroiliac joints are large pair of joints, one on each side of the body, which join the spine to the pelvis. They are surrounded by strong ligaments and muscles, and provide support and stability throughout the torso, hips and spine.

Sacroiliac dysfunction may occur from a variety of conditions (i.e., arthritis, pregnancy, sports injury) which cause inflammation or movement within the joint space.

Common symptoms of sacroiliac joint dysfunction include lower back, hip, groin, buttock, and sciatic leg pain.

A sacroiliac joint injection can both diagnose and treatment SIJ mediated pain, and is accomplished by injecting corticosteroid medication into, and around the joint.

The most common side effect is temporary pain at the injection site. Uncommon risks include infection, bleeding or worsening of symptoms.
