The sacroiliac joint, often called the SI joint, actually consists of two articulations, one on either side of the pelvis near the midline. Here, the sacrum --- the lowest part of the spine --- joins the ilium, or main pelvic bone. It is not designed to permit significant movement, and when runners injure the area, rehabilitation tends to be a lengthy process, requiring weeks or even months.
