Clinical Results

More than thirty published articles listed below have reported on the safety and effectiveness of the iFuse Implant System.1 iFuse is the only SI joint fusion device with published results from a randomized controlled trial and the only one with clinical studies demonstrating that treatment improved pain, patient function, and quality of life.2 Outcome measures include the visual analog scale (VAS), Oswestry Disability Index (ODI), quality of life (SF-36), and patient satisfaction with the surgery. An independent review of the company complaints database with information on over 5,000 procedures documents a low complaint rate and a low revision rate.3 The following summary tables include patients who underwent the iFuse procedure for SI joint disruptions or degenerative sacroiliitis.

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. Clinical studies have demonstrated that treatment with the iFuse Implant System improved pain, patient function, and quality of life. 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, click here.
