SI-BONE Inc. announced the publication of a single-center retrospective study of patients who underwent either sacroiliac joint fusion with triangular implants or sacroiliac joint fixation with cannulated screws.

According to the press release, SI-BONE’s iFuse Implant System is a triangular shaped minimally invasive surgical device designed for sacroiliac (SI) joint fusion. Its unique triangular shape reportedly prevents rotational motion and has a porous surface that promotes bony ongrowth. For the study, investigators reviewed medical records and tailored patient follow-up contact for patients who underwent SI joint fusion or fixation at the site between 2003 and 2015. The 4-year cumulative revision rates, calculated using Kaplan-Meier survival analysis, showed a 5.7% revision rate among the 263 patients who underwent SI join fusion with iFuse compared with a 30.8% revision rate among the 36 patients who underwent SI joint screw fixation. The full results of the study were published the International Journal of Spine Surgery.

“In our practice, we switched from screws to iFuse in early 2012 because we noticed that with iFuse, a much smaller proportion of patients returned to the clinic with complaints of continued SI joint pain,” Timothy Holt, MD, of Montgomery Spine Center and senior study author, said in the release. “Surgical revision was required in a large proportion of patients who underwent screw-based fixation. In contrast, the surgical revision rate with iFuse was low, similar to that reported in the literature.”
