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 […]

polymer bearings involving polyetheretherketone

0 Comments

APPLICATIONS AND BACKGROUND All-polymer bearings involving polyetheretherketone (PEEK) have been proposed for orthopaedic applications because they may reduce stress shielding, reduce weight of the implants, reduce wear and risk of osteolysis, and prevent release of metal ions by replacing the metal articulating components. Little is known about the biotribology of all-polymer PEEK bearings, including the […]

Biotribology of HXLPE on PEAK Bearings Little is known about the biotribology of all-polymer PEEK bearings!! Researchers from Philadelphia simultaneously tested a total of 100 pin-on-disk couples (n = 10 per bearing couple) consisting of three traditional metal-on-UHMWPE and seven polymer-on-polymer bearings for 2 million cycles under physiologically relevant conditions per ASTM F732. The combined […]
