The Trident® Ceramic Acetabular System is a ceramic-on-ceramic implant system used to replace the "ball and socket" joint of a hip when a total hip replacement is performed for patients suffering from arthritis or related conditions. Unlike conventional hip implants, the Trident® system utilizes alumina ceramic-on-ceramic surfaces rather than metal-on-plastic or metal-on-metal. Ceramic-on-ceramic components have demonstrated significantly lower wear versus the conventional metal-on-plastic or metal-on-metal systems in the laboratory; therefore, it is anticipated that these improved wear charac
