What is SI joint fusion?
The sacroiliac joint is a low-motion joint that connects the hip bones to either side of the sacrum, acting primarily as a shock-absorber between the lower body and torso. This joint can also be thought of as the point where the base of the spine connects to the pelvis. The sacroiliac joint is a combination of a synovial joint and the sacroiliac ligaments.
In a sacroiliac joint fusion, one or both sides of the sacrum is grafted to the ilium to encourage bone growth across the joint. Fusion occurs during the healing process following the surgery, and is achieved using implanted instrumentation and/or a bone graft.
