Designed to stabilize and fuse the SI joint

iFuse Implant SizesSI-BONE, Inc. has developed a minimally invasive surgical (MIS), innovative, patented, sacroiliac implant system for sacroiliac (SI) joint conditions including disruptions and degenerative sacroiliitis. There are potential risks associated with the iFuse Implant System. It may not be appropriate for all patients and all patients may not benefit.

The iFuse Implant System® consists of titanium implants and associated surgical instruments. Typically, patients receive three triangular-shaped titanium implants. Available implant lengths range from 30mm to 70mm in 5mm increments. These implants are delivered to the sacroiliac (SI) joint using a cannulated delivery system designed to protect soft tissue. The surgery is performed through a 2-3cm incision.

Potential iFuse benefits

  • Minimally invasive surgical (MIS) approach is less invasive than traditional fusion surgery without extensive soft tissue stripping
  • Triangular implant profile minimizes rotation
  • An interference fit between the implant and the adjacent osseous walls
  • Porous surface promotes bony ongrowth and ingrowth*
  • TPS technology used for decades in other medical applications such as orthopedics and dentistry
  • iFuse shape and coating are well suited for sacral bone
  • Designed specifically to stabilize and fuse the heavily loaded SI joint
  • Rigid titanium construction and implant geometry provide immediate stabilization 
  • More than thirty published, peer-reviewed articles demonstrate safety and effectiveness of the iFuse procedure.**

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

  • Preparation of the joint prior to implant
  • BMP or autologous bone graft
  • Additional pedicle screws and rods
  • Hollow modular anchorage screws
  • Cannulated compression screws
  • Threaded cages within the joint
  • Fracture fixation screws

Possible benefits versus traditional surgical SI joint fixation

  • Smaller incision size
  • Less soft tissue stripping
  • Minimal tendon irritation

Possible benefits of a minimally invasive surgical procedure

  • MIS procedure with small incision
  • Drill, broach, insert iFuse and close
  • Cannulated delivery system
  • Minimal blood loss

The iFuse Implant System is intended for sacroiliac fusion for conditions including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruption and degenerative sacroiliitis. This includes conditions whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum for more than 6 months. There are potential risks associated with the iFuse Implant System. It may not be appropriate for all patients and all patients may not benefit.
