Bio-tribological studies of non-UHMWPE Polymers and Composites
30 June 2022 12.30 BST. Register Ultra-high molecular weight polyethylene (UHMWPE) has been the main polymeric articulating implant material for the hip implant. Acetabular cup is made of UHMWPE in its unmodified form or with partial cross-linking and with Vitamin E added into it as the anti-oxidant. Many efforts in the past have been made on finding an alternative material to UHMWPE in the hope of improving upon the already excellent tribological performance of this polymer. Several of UHMWPE composites and other polymers such as polyetheretherketone (PEEK) and polymer gels have been researched with some even tried in for in-vivo tests. In this talk, we will review the tribological performances of non-UHMWPE polymeric materials for the acetabular cup application and compare those with…
