Sacroiliac (SI) Joint Fusion

What is the sacroiliac joint?

The sacroiliac (SI) joint connects the sacrum to the ilium bone of the pelvis (see diagram below). This joint is responsible for bearing upper-body weight and transmitting it to the pelvis and legs.

What is SI joint dysfunction and what are the symptoms?

Dysfunction in this joint causes pain in the joint itself, and the pain can spread to the buttocks, groin, thighs, and lower back. Usually this pain is only felt on one side of the body from one joint.

What is a sacroiliac joint fusion?

An SI joint fusion is the process of fusing the sacrum to the pelvis. Most SI joint fusions are minimally invasive. The minimally invasive procedure involves the surgeon making several small incisions in the buttocks, drilling a few large holes in the sacrum and ilium, and implanting screws to hold the joint completely stable. Over time, the two bones fuse together.
