Jim Nevelos, Ph.D., from Stryker Orthopedics provides an overview of the development of the first CFR-PEEK bearings for hip replacement currently under clinical trial. All contemporary orthopaedic bearings have issues with wear, wear debris, noise generation, and fracture risk. PEEK has great promise as a bearing material, although the ideal formulation and design has proven elusive.


Jim Nevelos, Ph.D., Director, Hip Research, Orthopaedics
Following a degree in Materials Science and Engineering and a Masters in Tribology, Jim went on to complete his PhD on the Tribology of Ceramic on Ceramic Hip Joints. As part of this work there were publications on the phenomenon of Stripe Wear and the first reproduction of this in the laboratory using Micro-separation conditions. Jim has held Product Management positions at Corin and Zimmer working with hip resurfacing in particular before joining Stryker Europe to manage their conservative hip and tribology programs for Europe. Currently the Director of Hip Research at Stryker Orthopaedics in the USA, Jim has also published on the design and wear of dual mobility articulations, metal on metal hips, surface engineering and uni-compartmental knees.
