This presentation covers research at the University of Waterloo directed to understanding the tribology of PEEK-on-PEEK bearings, primarily for cervical disc arthroplasty applications. Tribological assessment was performed using a multi-directional pin-on-disc tribometer (OrthoPOD) with clinically relevant lubrication. The testing program also incorporated adverse, high stress conditions.

Dr. John Medley a Professor of Orthopaedic Tribology in the Dept. of Mechanical and Mechatronics Engineering, Waterloo University.
