What is sacroiliac joint dysfunction?
Sacroiliac joint dysfunction is an injury or inflammation of the joint, which may cause pain in the lower back, buttocks and some times groin and legs.

Pain may also begin after simple twisting motions that combine bending forward, tilting the pelvis, or twisting the trunk as in a golf swing, shoveling snow, or bending and reaching sideways to pick an object off the floor.
