title: Catastrophic failure of modular zirconia-ceramic femoral head components after total hip arthroplasty.
abstract: Catastrophic failure of two zirconia-ceramic modular femoral heads occurred, despite the theoretical improved toughness of zirconia-ceramic relative to alumina-ceramic. This experience led the authors to return to cobalt-chromium as the metal of choice for articulation against polyethylene in total hip arthroplasty.
