Abstract
Magnesia-partially stabilised zirconia (Mg-PSZ) is one of the toughest-known ceramic materials. Over the last decade there has been an evaluation of these materials for biomedical applications including hip endo-prosthesis. These studies have examined the bio-compatibility, strength, fatigue and environmental stability. More recently these observations have been complemented with wear evaluation tests using an anatomical designed hip wear simulator and extensive clinical observations. This paper will review the data available.
