摘要: The outstanding chemical stability and tribologic properties of polymers have favored their introduction as implant materials. In 1946 the Judet Bros. [5] introduced polymethylmethacrylate a material for femoral endoprostheses. 1958 Charnley used polytetrafluoroethylene (Teflon) an acetabular prosthesis which was cemented into place with cold-curing polymethylmethacrylate. When Teflon showed unacceptable degree wear, [2, 3] high-density polyethylene alternative prostheses.
