Bone Formation with PEEK/HA Composites


Bone Formation with PEEK/HA Composites in a Sheep Fusion Model

Researchers from Prince of Wales Hospital in Australia investigated bone ongrowth and fusion outcomes of PEEK/HA as compared with natural PEEK in a cervical fusion model. Incorporating HA into the PEEK matrix resulted in more direct bone apposition as opposed to the fibrous tissue interface with PEEK alone in the bone ongrowth as well as interbody cervical fusions. No adverse reactions were found at the implant-bone interface for either material.

PAEK Variation

Polyaryletherketone (PAEK) is a family of semi-crystalline thermoplastics with high-temperature stability and high mechanical strength. Plastics that fall within this family include:

  1. Polyetherketone (PEK)
  2. Polyetheretherketone (PEEK)
  3. Polyetherketoneketone (PEKK)
  4. Polyetheretherketoneketone (PEEKK)
  5. And the wonderfully named polyetherketoneetherketoneketone (PEKEKK)
