The Silex™ system allows for fusion and stabilization of the SI Joint in eligible patients where appropriate non-surgical treatment has failed. The Silex™ Sacroiliac Joint Fusion System is intended for sacroiliac joint fusion for conditions including degenerative sacroiliitis and sacroiliac joint disruptions. The device optionally incorporates a proprietary dual-pitch compression-thread design and titanium plasma coating to stabilize the SI Joint in fusion procedures. The design of the implant allows for bone graft to be introduced into the joint and implant in order to promote fusion. The Silex™ is a true bony fusion and arthrodesis system. The implant and instrumentation suite allows for direct exposure and preparation of the SI Joint surface, placement of bone graft into the SI Joint space under direct visualization, and placement of bone graft directly within the Silex™ implant itself.
