Clinical Research Studies

The purpose of this study is to determine if placing an additional device, called iFuse-3D, across the SI joint (joint between the bottom of the spine and the pelvic bone) during a Multi-level (MLF) spine surgery provides benefits compared to surgeries without the device. In this study, participants will be randomly assigned to either receive the iFuse-3D device during the MLF spine surgery or not. The iFuse-3D device is Food and Drug Administration (FDA) cleared and currently available on the market for SI joint fusion during multi-level spine surgeries. The purpose of this study is to see if using the iFuse-3D device helps improve the outcome of the MLF spine surgery.
