iFuse Implant System: Minimally Invasive Sacroiliac Joint Fusion

Most recently, minimally invasive techniques for sacroiliac joint arthrodesis have been developed.

The iFuse Implant System® is an innovative, patented implant system, intended for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis.

The iFuse procedure is performed under fluoroscopic guidance using a posterior-lateral approach. The implants are positioned across the joint over pins through a small, 3 - 4 cm incision. No muscle detachment or extensive soft tissue stripping is required.

The triangular shaped implants provide a large surface area, which maximizes post-surgical weight bearing capacity. The implants are rigid titanium with a porous coating commonly used in orthopeadics such as hip or ankle replacements.

With the iFuse Implant System, there is no need for:

  1. Decortication of the joint surface,
  2. BMP or autologous bone graft, or
  3. Additional hardware, such as screws, rods, or cages

Additionally, the iFuse Implants can be utilizeded in the presence of lumbar fusion devices, and they create a stronger construct that is 3 times more resistant to shear forces, and nearly 4 times more resistant to bending forces than cannulated titanium screws.23

Other minimally invasive sacroiliac joint fusion or fixation devices have been cleared for use in the U.S. and/or EU, using cannulated titanium or hydroxyapatite coated screws. Traditional open fusion techniques require bone grafting and a period of non-weightbearing. Though there is currently no published data on the iFuse sacroiliac joint fusion procedure, clinical studies are currently underway.

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.  Please review the iFuse Instructions For Use for a complete discussion of contraindications, warnings, precautions, and risks.
