Product Specifications


Bio-implant designed with two cortical endplates supporting a cancellous center for ACDF procedures

*For International Use Only

  • Proven Clinical Performance: A prospective study found 100% fusion rates after 12 months in 74 ACDF patients.1
  • Osteoconductive: Large cancellous matrix facilitates early bone growth.
  • Stability: Textured surface designed to reduce migration.2
  • Variety: Multiple footprints in both parallel and lordotic configurations to better match patient anatomy.
  • Sterile: Sterilized using proprietary and patented Allowash XG® technology. This technology provides a sterility assurance level of 10-6, without compromising the implant’s inherent osteoconductive properties.3
  • Ambient Storage: This implant features Preservon®; a proprietary, glycerol-based preservation technology that allows allograft bio-implants to be stored in a fully-hydrated state at ambient temperature. Preservon eliminates lengthy thawing and rehydrating times, and does not require freezer storage, or compromise biomechanical strength.4
  • Uniform dimensions.
