Minimally Invasive Solution

SI-BONE, Inc. has developed a minimally invasive surgical (MIS), innovative, patented, sacroiliac implant system to treat sacroiliac (SI) joint dysfunction. 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 55mm in 5mm increments. These implants are delivered to the sacroiliac (SI) joint using a cannulated delivery system and soft tissue protection instruments. All this is performed through a 2-3cm incision.


The iFuse Implant System is indicated for sacroiliac joint fusion for conditions including sacroiliac joint disruptions and degenerative sacroiliitis.

iFuse benefits

  • Minimally invasive surgical (MIS) approach is less invasive than traditional fusion surgery with no extensive soft tissue stripping
  • Rigid titanium constructs provide enhanced stability
  • Porous plasma spray coating with irregular surface designed to support stable bone fusion
  • Larger implant surface area designed to maximize post-surgical weight bearing capacity
  • Biomechanically rigorous implant designed specifically to stabilize the heavily loaded SI joint

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

Minimally invasive surgical (MIS) solution compared to traditional surgical SI joint fixation

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

Simplified surgical procedure anticipated...

  • MIS device with small incision
  • Just drill, broach, insert iFuse and close
  • Cannulated delivery system
  • Minimal blood loss
  • Less post-surgical call-back to OR
  • Fewer complications
  • Reduced risk of infection

Potential for earlier patient weight bearing

  • Improved patient perception of stability based on clinical case study reports (data on file).

iFuse Implant System versus traditional SI joint fusion

  • Bony interference with iFuse Implant System versus none with screws
  • No conflicts with lumbar fusion devices
  • Stronger construct versus traditional SI joint fusion
