Advancing the understanding of the sacroiliac joint. 

SI-BONE is focused on advancing the understanding of the sacroiliac joint. Educated patients tend to be more invested in their treatment and work more freely with their doctors. The resources on this site are designed to help you better understand the SI joint and the iFuse Implant System, a surgical option for some causes of SI joint pain. SI joint treatment using the patented triangular design of the iFuse Implant™ has produced unparalleled clinical results. More than thirty published, peer-reviewed articles demonstrate safety and effectiveness of the iFuse Implant System.1 iFuse is the only SI joint fusion system with multiple clinical studies demonstrating that treatment improved pain, patient function, and quality of life.2
