Analysis of the taper supports retention of a well-fixed stem in revision surgery of metal-on-metal hip replacements

Summary. Retrieval analysis of metal-on-metal hip stems showed negligible wear (<1mm3) of the male taper surface in all cases. This supports retention of a well-fixed, undamaged stem during revision surgery Introduction. Wear and corrosion at the taper junction of metal-on-metal total hip replacements (MOM-THR) is likely to contribute to the high revision rates reported by joint registries. Studies have shown significant volumes of measured...
