Prospective comparative wear study of bearing surfaces between oxidized zirconium (Oxinium) and highly cross-linked polyethylene in total hip replacements

Abstract

Osteolysis resulting from wear debris is a major factor limiting long term survival of hip implants. Oxidized zirconium head (OxiniumTM) on crosslinked polyethylene (XLPE) is a modern bearing coupling, introduced to reduce wear debris. However several issues require further investigation: Does this bearing couple produce less wear debris than the combination of ceramic head on XLPE or conventional polyethylene (CPE)? What bearing couple has better clinical performance? A total of 199 patients who underwent total hip replacement for osteoarthtritis were evaluated clinically and radiologically, with a follow-up of 12- 16 years, by measuring in vivo, linear wear, linear wear rate, volumetric wear and volumetric wear rate by using PolyWare® software. All bearing couples showed a varying high bedding-in effect (plastic deformation of the liner) up to the second postoperative year. In this study, in vivo wear parameters were lower when the combination of OxiniumTM head on XLPE was used, at 5 ...
