AURORA SPINE ANNOUNCES PUBLICATION OF BIOMECHANICAL STUDY DEMONSTRATING SUPERIORITY OF SILO TFX SACROILIAC FUSION SYSTEM

A new clinical study regarding Aurora Spine Corp.'s SiLO TFX MIS sacroiliac joint fixation system titled "Fixation of the Sacroiliac Joint: A Cadaver-Based Concurrent-Controlled Biomechanical Comparison of Posterior Interposition and Posterolateral Transosseous Techniques" has been published in the journal Neurospine. The study evaluates the biomechanical performance of Aurora Spine's SiLO TFX MIS sacroiliac joint fixation system compared with traditional posterolateral transosseous techniques.

The SiLO TFX system 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, an ilium screw, a sacrum screw and associated instrumentation, engineered to transfix the sacrum and ilium, thereby providing stability conducive to bony fusion. The SiLO TFX system is designed in accordance with the AO Principles of Fusion -- providing mechanical stability, preserving vascular supply, minimizing soft tissue disruption, and promoting an optimal environment for bone healing by proper decortication and the use of bone graft.

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 with the posterolateral transosseous technique. Specifically, the posterior interposition technique resulted in a 42-per-cent-plus-or-minus-8-per-cent reduction in nutation/counternutation motion of the sacroiliac joint, outperforming the 14-per-cent-plus-or-minus-4-per-cent 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 per cent to 50 per cent of specimens.

Trent Northcutt, president and chief executive officer of Aurora Spine, expressed satisfaction with the outcomes of the biomechanical study conducted. "The study demonstrated the superior performance of the SiLO TFX system in sacroiliac joint fusion. These findings align with Aurora Spine's commitment to developing innovative, minimally invasive solutions that optimize patient outcomes and establish new standards in sacroiliac joint care."

Dr. Michael Stoffman, University at Buffalo Neurosurgery, Buffalo, N.Y., one of the study's authors, stated: "The posterior interposition technique demonstrated significant advantages in reducing joint motion and preserving bone integrity. This approach offers a promising alternative to traditional methods, potentially leading to improved patient recovery and long-term success."

Dr. Steven M. Falowski from Neurosurgical Associates of Lancaster, Lancaster, Pa., added: "Our research indicates that the SiLO TFX system provides enhanced stability and durability in sacroiliac joint fixation. The reduced bone removal and increased fusion surface area are critical factors in achieving successful surgical outcomes."

Dr. Jason E. Pope, Evolve Restorative Center, Santa Rosa, Calif., remarked: "The study's outcomes highlight the biomechanics of the posterior interposition technique in sacroiliac joint fusion. The data suggests it is a viable treatment option for those suffering from sacroiliac joint disease, and future clinical data on safety and efficacy is ongoing."

Aurora Spine remains dedicated to advancing spinal health through continuous innovation and collaboration with leading medical professionals. The publication of this study reinforces the company's position at the forefront of spinal implant technology.
