A new study examines the surgical implant survivorship of minimally invasive sacroiliac joint fusion, published in Dove Press.
The researchers examined revision surgeries and linked them to index surgeries. They calculated the likelihood of revision surgery with the Kaplan-Meier life table approach. The researchers found:
1. Four-year survivorship without revision was 96.46 percent for minimally invasive SI joint fusion using the iFuse Implant System from SI-BONE.
2. The revision rate was similar for patients for both sexes.
3. The revision rate was lower for patients who were younger than 65 years old.
4. Twenty-four percent of the revisions occurred within 30 days of surgery; 63.5 percent of the revisions occurred within the first year.
5. The survivorship improved annually since 2009 when the device was introduced.
