The CD HORIZON LEGACY PEEK Rod System uses rods made of polyetheretherketone, a semi-crystalline thermoplastic polymer that meets all biocompatibility requirements and has a long history of use in surgical implants. When combined with CD HORIZON® Spinal System-based pedicle screws and minimally invasive approach options such as the MAST QUADRANTTM Retractor Set, the CD HORIZON LEGACY PEEK Rod dynamically stabilizes the affected segment while allowing for a streamlined surgical technique that preserves much of the natural anatomy.
