With more than fifteen years of clinical history, PEEK-OPTIMA Natural polymer, is the first medical-grade PEEK used in spinal fusion surgeries. PEEK is currently the most popular biomaterial for interbody fusion, accounting for 73% of all devices used in 2016.1 Clinical studies suggest that PEEK-OPTIMA performs as well as, or better than, interbody fusion devices made of metals or bone, while providing some distinct clinical advantages over competing biomaterials including:

  • Modulus similar to bone
  • Reduced stress shielding
  • Artifact-free imaging

Invibio continues to revolutionize the spinal fusion market with the introduction of PEEK-OPTIMA HA Enhanced. Hydroxyapatite (HA), a well-known osteoconductive material that enhances bone apposition, is fully integrated, not coated, into the PEEK-OPTIMA matrix, making it available on all surfaces of a finished device. While offering all of the benefits of PEEK-OPTIMA Natural polymer, pre-clinical studies have demonstrated potential performance advantages when comparing against it including:

  • Earlier bone ongrowth with >75% direct bone contact after 4 weeks2
  • Enhanced bone apposition at 12 weeks2
  • Greater new bone formation at 6 weeks3
  • Higher quality new bone bridging at 6 and 12 weeks3
  • Bone ongrowth on the endplates and all faces of the interbody device3
  • Superior mechanical performance outperforming allograft in 46% of the instances3

Early clinical results for cervical and lumbar spinal fusion indicate potential benefits and reveal specific improvements as observed by surgeons4:

  • Solid fusions as early as 6 months
  • Dense bone apposition at the bone-implant interface
  • Positive clinical outcomes at early time points
  • Improvements in overall pain and neurological function

  2. Study evaluated the bone ongrowth of PEEK-OPTIMA Natural and PEEK-OPTIMA HA Enhanced in a bone defect model in sheep. Data on file at Invibio. This has not been correlated with human clinical data.
  3. Study evaluated the in vivo response to PEEK-OPTIMA Natural, PEEK-OPTIMA HA Enhanced and allograft in a cervical spine fusion model in sheep. Data on file at Invibio. This data has not been correlated with human clinical experience.
