SI-BONE is a medical device company that pioneered the iFuse Implant System, a minimally invasive surgical system for fusion of the sacroiliac joint to treat sacroiliac joint dysfunction. The SI joint is believed to be the last major joint to have a clinically proven surgical treatment. The iFuse Implant, commercially available since 2009, is believed to be the only SI joint fusion device supported by multiple prospective clinical studies showing improved pain, patient function and quality of life resulting from treatment. There are more than 65 peer-reviewed publications supporting the safety, effectiveness, and biomechanical and economic benefits unique to the iFuse Implant. This body of evidence has enabled multiple government and private payors to establish coverage of the SI joint fusion procedure exclusively when performed with the iFuse Implant System.
