The results demonstrated greater than 85 percent reduction in SIJ pain at six weeks and radiographic evidence of the presence of solid continuous bridging bone across the treated joint at six months. No procedure- or device-related serious adverse events were reported.
A unique feature of the CAT SIJ Fixation System procedure is the ability to directly visualize the joint allowing for a significant increase in reimbursement for the surgeon and facility payments.
"This single implant SIJ fusion system allows me to use either a navigated procedure or fluoroscopic imaging providing flexibility in access and visibility. The implant is designed to breach the SIJ and allow for bone graft materials to be loaded and delivered to the SIJ before and after implant placement to promote fusion of the SIJ. The unique trajectory eliminates the risk of sacral nerve root injury encountered with other fusion techniques and reduces the risk of entry into the retroperitoneal space. By supplementing fixation with decortication and bone grafting, I can be confident that my patients have the best possible foundation for biological fusion, and long-term relief," said Dr. Michael Chaparro.
"Our unique approach is designed to drastically reduce procedure time and represents a landmark innovation for SIJ fusion surgery benefiting patients, surgeons, facilities, and payers," said Dr. Kal Mentak, CEO of Tenon Medical.
In November 2016, Tenon Medical Inc. was granted the first U.S. patent covering a novel posterior approach SIJ fusion system. The company has since filed for additional compositions.
