How It Works

SI Joint Fusion with the iFuse Implant System®

The iFuse System is intended for sacroiliac joint fusion for conditions including 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.

The iFuse Implant System is designed to provide fusion for the sacroiliac joint. This is accomplished by inserting small titanium implants across the sacroiliac joint to maximize post-surgical stability and weight bearing capacity.

Potential iFuse benefits

  • Minimally invasive surgical (MIS) approach is less invasive than traditional SI joint surgery
  • Implant profile and design minimizes rotation and micromotion
  • Rigid construct provides for enhanced stability
  • Porous plasma spray coating with irregular surface designed to support stable bone fusion
  • Large implant surface area designed to maximize post-surgical weight bearing capacity
  • Biomechanically rigorous implant designed specifically to stabilize the heavily loaded SI joint

Possible benefits of an MIS procedure

  • MIS device with small incision
  • Minimal 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
