Abstract

Clinical application of alumina ceramic to femoral head of prostheses has been performed with possible advantage of lower friction of ceramic head / ultra-high molecular weight polyethylene (UHMWPE) or ceramic head /ceramic cup articulations, when compared to that of metal head / UHMWPE cup. Although favorable clinical results of alumina ceramic head / UHMWPE cup combination has been known, breakage of alumina ceramic head has been reported. In this study, we investigated the series of total hip arthroplasties (THAs) with alumina ceramic head, and reported breakage of alumina ceramic head combined with UHMWPE cup and critical clinical problems after tiny modification of the taper system between alumina ceramics head and metal neck.
