Aurora Spine announced the publication of a new clinical study, “Fixation of the Sacroiliac Joint: A Cadaver-Based Concurrent-Controlled Biomechanical Comparison of Posterior Interposition and Posterolateral Transosseous Techniques.” The study evaluates the biomechanical performance of Aurora Spine’s SiLO TFX MIS Sacroiliac Joint Fixation System compared to traditional posterolateral transosseous techniques.​
SiLO TFX is a minimally invasive solution designed for sacroiliac joint fusion, addressing conditions such as sacroiliac joint disruptions and degenerative sacroiliitis. The system includes a Transfixing-Cone, ilium screw, sacrum screw and associated instrumentation, engineered to transfix the sacrum and ilium, thereby providing stability conducive to bony fusion.
The study’s findings indicate that the posterior interposition technique, as employed by the SiLO TFX system, removes less bone volume and offers a larger surface area for bony fusion compared to the posterolateral transosseous technique. Specifically, the posterior interposition technique resulted in a 42% ± 8% reduction in nutation/counternutation motion of the sacroiliac joint, outperforming the 14% ± 4% reduction observed with the posterolateral transosseous technique.
Furthermore, upon fatigue loading, the posterior interposition implant maintained the bone-implant interface across all specimens, whereas the posterolateral transosseous implant exhibited migration or subsidence in 20%–50% of specimens.
