FDA cleared Xenix Medical's Riva Anchor Spinopelvic Fixation System on September 22. The implant fuses the sacroiliac joint at the base of a posterior lumbar or thoracolumbar construct.

The Orlando company built it as a dual lead, fully threaded implant with self-harvesting bone apertures, sized for 5.5mm and 6.0mm rods. Surgeons can place it open, under fluoroscopy or with navigation. The surface is Xenix's NanoACTIV texture, which the company says FDA has designated as having an osteogenic effect. Riva Anchor follows two other Xenix clearances this year, the Riva Posterior Fixation System in June and the Lux expandable lumbar interbody cage days later. A limited commercial launch comes first.
