Abstract

The purpose of this study was to characterize wear stripes on explanted third generation ceramic-on-ceramic components. Macroscopy, light microscopy and scanning electron microscopy (SEM) was carried on the wear stripes to determine their extent and the material failure mechanism that led to their formation. The analysis shows that the wear stripes were formed through high stress, point contact of the head on the rim of the cup. This type of damage occurs due to microseparation of the head and cup during specific patient activities.
