Metal/metal articulating interfaces.

Abstract

Polyethylene wear can be shown as a problem in long-term joint replacement. Metal-on-metal bearing is solving this problem, as long-term clinical and experimental investigations demonstrate. To avoid the problem of high friction found in old series, a new Metasul called technique with a smaller diameter was invented. Intermediate results of Weber and our own data show promising outlook for a solution to the wear-induced problem in hip replacement.
