Overview
Sacroiliac joint fusion is a procedure which involves the fusion of the SI joint, the joint that is formed by the base of the spine (sacrum) and the pelvis. This procedure is used to treat sacroiliitis and SI joint dysfunction that is unresponsive to conservative treatment (see sacroiliitis). A small incision is made over one side of the pelvis, and a dissection is carried through a small amount of muscle to the pelvis. Using x-ray guidance, three screws are placed through the SI joint thereby immobilizing and fusing the joint.
Post operative expectations
Many patients report rapid relief of symptoms shortly after surgery. Activity is restricted for a short time after surgery. Most patients can return to work after 4 weeks and are ready to return to full, unrestricted activities by 3 months.
