SI Joint Fusion with the iFuse Implant System - How iFuse Works | SI-BONE

SI Joint Fusion with the iFuse Implant System®

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 sacroiliitis. 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. Click here to see the potential risks associated with the iFuse Implant System.

Sacroiliac (SI) joint fusion is a surgical procedure performed in an operating room, with either general or spinal anesthesia. You will be lying down during the surgery while your surgeon uses a specially designed system to guide the instruments that prepare the bone and insert the implants. Both the surgical technique and the iFuse Implant System are designed to offer the maximum protection to your surrounding tissues.

The entire procedure is performed through a small incision (approximately 2-3cm long), along the side of your buttock. During the procedure, fluoroscopy provides your surgeon with live imaging during the procedure to facilitate proper placement of the implants. Fluoroscopy is an imaging technique commonly used by physicians to obtain real-time moving images of internal structures using X-rays. Normally three implants will be used, depending on your size.

The procedure takes about an hour. Your surgeon will decide when you can return home based on your postsurgical status.

Following the Surgery

At discharge, your surgeon will arrange follow-up visits to assess your progress, health status (including the status of your incision) and may take additional images of your surgical site. Your doctor will advise you when it is appropriate to resume your daily activities and weight bearing. Return to work will depend on your postsurgical progress and occupation.

iFuse Implant System ImplantsPotential iFuse benefits

  • Minimally invasive surgical (MIS) approach is less invasive than traditional SI joint surgery
  • Triangular implant profile minimizes rotation and an interference fit minimizes micromotion
  • Designed specifically to stabilize and fuse the heavily loaded SI joint
  • Rigid titanium construction and implant geometry provide immediate stabilization
  • No conflicts with lumbar fusion devices

Possible benefits of an MIS procedure may include:

  • Smaller incision
  • Reduced blood loss
  • Decreased OR time

Possible benefits versus traditional SI joint fusion

  • Smaller incision size
  • No need for bone grafting
  • Less soft tissue stripping
  • Minimal tendon irritation
