Background:
Sacroiliac joint (SIJ) pain is a common source of chronic low back pain, accounting for 15% to 30% in patients without disc herniation or radicular pain. Multiple advances have been made in managing SIJ pain with the development of minimally invasive SIJ fusion devices. Minimally invasive SIJ fusion with a posterior approach has shown promising results in recent literature. One of the newly developed SIJ fusion devices utilizing a posterior approach is SiLO TFX™, Transfixing Bridge, a titanium device. The device uses a posterolateral approach with a single transfixing cone and ancillary ilium and sacrum screws. The case reports presented herein are the first cases of SIJ fusion performed with SiLO TFX™ Transfixing Bridge in the United States.
Case Report:
Two patients with chronic bilateral sacroiliitis refractory to conservative management with greater than 75% short-term relief with sacroiliac injections, underwent SIJ fusion surgery with a novel transfixing bridge titanium device, the SiLO TFX™. Both patients showed resolution of the SIJ pain.
Conclusion:
These case reports discuss the unique aspects of the novel device, procedural steps, and early postoperative results, filling a gap in the current literature on titanium-based SIJ fusion.
