The iFuse Implant System® is a procedure that fuses the sacroiliac joints together to treat sacroiliac joint dysfunction caused by deterioration or disruption of the sacroiliac joint. This includes symptoms that began during pregnancy or in the peripartum period and have persisted beyond 6 months after delivery. This product is also helpful for patients who need sacroiliac fusion to improve immobilization and stabilization of the sacroiliac joint. It works well 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.

If your doctor confirms that your SI joint is the source of discomfort, they will begin treatment options. Some people see significant improvement from physical therapy, SI belt wear, or taking an oral medication, however, these solutions are not always permanent. Surgery may be an option if you have tried other methods without finding long-term relief – including the minimally invasive iFuse procedure.
SI Joint Fusion with the iFuse Implant System®
The iFuse Implant System is meant to stabilize and fuse the SI joint. To improve SI joint stability, reduce pain, and increase function, the iFuse technique involves inserting triangular-shaped titanium implants across the sacroiliac joint. The operation takes about an hour via a tiny one-inch incision. The Triangular Design of the iFuse Implants has been clinically evaluated more than any other SI joint fusion surgery.
Dr. Morton has extensively trained in minimally invasive surgical (MIS) techniques, including the iFuse Implant System® from SI-BONE®, a medical device company specializing in MIS sacroiliac (SI) joint treatment. The iFuse implant is backed by over 100 peer-reviewed publications detailing its safety, long-term effectiveness, and biomechanical/economic benefits (www.si-bone.com/results). Furthermore, the iFuse implant is the only SI joint fusion device supported by multiple prospective clinical studies–including two randomized controlled trials affirming that treatment with the iFuse improves pain, patient function, and quality of life. The iFuse Implant System, like any minimally invasive surgical treatment, comes with a number of possible hazards. It may not be suitable for some patients or everyone may not profit from it.
