Alumina ceramic bearings have known superior wear resistance and lubrication and do not carry a risk of ion release. There were 328 hips implanted as part of a multicenter USIDE prospective and randomized study. The study compared alumina-on-alumina ceramic bearings to a controlled cobalt chrome-on-polyethylene bearing. A nonrandomized fourth arm of the study, the Trident arm, was later added and 209 Trident alumina ceramic bearings were implanted. No ceramic fracture or alumina ceramic bearing device failures have occurred. This new alumina ceramic hard bearing provides a safe option for the younger and more active patient and seeks to eliminate the risk of past experiences with ceramic implants.
