SI Joint Fusion
SI Joint Fusion with the iFuse Implant System®
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. It is also intended for sacroiliac fusion to augment immobilization and stabilization of the sacroiliac joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion or for acute, non-acute, and non-traumatic fractures involving the sacroiliac joint. 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 is designed to stabilize and fuse the SI joint. The iFuse procedure involves inserting typically three triangular-shaped titanium implants across the sacroiliac joint to maximize SI joint stability, reduce pain, and improve function. The procedure is done through a small one-inch incision and takes about an hour. SI joint treatment using the patented triangular design of the iFuse implant has been clinically evaluated more than any other SI joint fusion procedure.
The iFuse Implant System is designed to provide stabilization and fusion for certain SI joint disorders
More than 100, peer-reviewed publications demonstrate the safety, durable effectiveness, and biomechanical and economic benefits of the iFuse implant (www.si-bone.com/results). The iFuse implant is the only SI joint fusion device with multiple prospective clinical studies, including two randomized controlled trials6,7, demonstrating that treatment improved pain, patient function, and quality of life.6-11 As with any minimally invasive surgical procedures, there are potential risks associated with the iFuse Implant System. It may not be appropriate for all patients and all patients may not benefit. For information about the risks, visit www.si-bone.com/risks.
