About SI Joint Fusion using the iFuse Implant System®

Sacroiliac joint fusion is a surgical procedure intended to stabilize the joint and eliminate motion. The iFuse Implant System is indicated for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis. This system uses small titanium implants placed across the sacroiliac joint to stabilize and fuse it. (Figures 2,3)  In most cases, the implants may be used on patients who have had prior spine surgery.

Sacroiliac joint fusion is a surgical procedure in which the joint is fixed into its intended position and for weight-bearing function.  The iFuse Implant System accomplishes this by inserting three small titanium implants across the joint to stabilize and fuse it.  The implants are small triangular-shaped devices about the size of your little finger.

Traditional sacroiliac joint fixation involves open surgery that may take several hours.  Open surgery typically involves a large incision to access the SI joint, bone removal, and adding bone graft to help the joint heal.  Open surgery usually translates into several days of hospitalization.  The potential advantages of the SI-BONE iFuse Implant System include:

  • Minimally invasive surgical (MIS) approach
  • Triangular implant profile minimizes rotation and an interference fit minimizes micromotion
  • Porous titanium plasma spray coating allows for biological fixation
  • Designed specifically to stabilize and fuse the heavily loaded SI joint
  • Rigid titanium constructs and large implant surface area provide stability
  • No conflicts with lumbar fusion devices

About the Procedure
SI joint fusion using iFuse is performed in an operating room under general or spinal anesthesia.  Your doctor uses a specially designed system to guide the instruments that prepare the bone and insert the iFuse Implants.  The surgical technique and the iFuse Implant System are designed to offer the maximum protection to your surrounding tissues and minimize soft tissue exposure.

The entire procedure is performed through a small incision (2-3cm) made along the side of your buttock.  During the procedure fluoroscopy (real time X-ray) provides your doctor visual feedback to enable proper placement of the implants. The number of implants used depends upon your size.

The procedure typically takes about an hour.  Your doctor will make the decision for how many days that you remain in the hospital based on your post-surgical status.

This information is not intended to take the place of a doctor's advice. Please keep in mind that treatment and outcome results vary among patients. The iFuse Implant System® is intended for sacroiliac joint fusion for conditions including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruptions and degenerative sacroilitis. As with all surgical procedures and permanent implants, there are risks and considerations associated with surgery and use of the iFuse Implant. You should discuss these risks and considerations with your physician before deciding if this treatment option is right for you.
