Osteolysis Associated with Polythene Liners in Hydroxyapatite Hip Arthroplasty


Article Preview

Wear debris contributes to the development of granulomatous debris disease and loosening. It is accepted that hydroxyapatite ceramic (HA) will bond a prosthesis to bone.[1,2] Osteolysis has not been seen for several years after implantation but cases are now emerging [3]. Is HA still working? Should we use hard on hard bearings? Should we abandon polythene liners? With a modular hip system, patients with polythene acetabular liners have been compared with those with ceramic liners. Polythene liners wear out and patients with a life expectancy of more than ten years should have ceramic/ceramic bearings.
