Minimally invasive SIJ fusion, performed across multiple implant systems and surgical techniques, yields large, clinically meaningful, and reproducible improvements in pain and disability with a low reoperation rate. Outcomes are most favorable when patient selection is rigorous and SIJ dysfunction is accurately identified as the primary pain generator using diagnostic SIJ injection, underscoring the importance of standardized diagnostic pathways in optimizing surgical benefit.
