The RFS™ (Resorbable Fixation System) Screw features a small, low-profile resorbable screw head, industry standard compatible screw thread design and a detachable industry standard compatible head adaptor offering ease of insertion and greater confidence. ach RFS™ Screw is constructed of oriented bioresorbable L-lactic/co-glycolic acid copolymer (PLGA 85L/15G) and is provided in a secure, "no-touch" aseptic Screw Holder.
The proprietary manufacturing process results in an implant with high initial mechanical strength and stiffness, delivering reliable, controlled strength-to-resorption characteristics. As the implant resorbs, the bone gradually restores its load carrying capacity.
The RFS Screw also offers Auto-Compression. The implant is designed to change its dimensional characteristics in hydrolytic conditions. Diameter increases and length decreases 1% - 2% compared to initial dimensions (as seen below). This innovative feature provides sustained compression during bone healing and reduces the risk of unstable fixation.
