Clinical Results of iFuse SI Joint Fusion

The iFuse Implant, cleared by the FDA in 2009, is the only device for treatment of SI joint dysfunction that is supported by significant published clinical evidence, including two Level I Randomized Controlled Trials (RCTs). The clinical evidence shows safety, durable effectiveness, and lasting relief from SI joint pain.
