VertiGRAFT® ACIS VG2®

Bio-Implant designed with two cortical endplates supporting a cancellous center for ACDF Procedures.

  • Proven Clinical Performance: The cortical cancellous design optimizes strength and clinical success. A prospective study found 100% fusion rates after 12 months in 74 ACDF Patients.1
  • Osteoconductive: Large cancellous matrix facilitates bone growth and remodeling in accordance with Wolff’s Law.
  • Stability: Textured surface and multiple footprints optimize fit and fill while reducing migration.
  • Sagittal Balance: Available in both neutral and lordotic footprints to reproduce and correct the anatomy.
  • Convenience: Preservon® is a proprietary, glycerol-based preservation technology that allows LifeNet Health allograft implants to be stored in a fully hydrated state at ambient temperature. Lengthy thawing or rehydration time is eliminated with out compromising allograft strength.2
  • Sterile: Sterilized using proprietary and patented Allowash XG® technology. This technology provides a sterility assurance level of 10-6, without compromising the implants inherent osteoconductive properties.3
