The author and Sulzer Medical Technology Ltd, Switzerland, have developed a new generation of metal on metal bearing total hip joints. The design is different than the McKee type prostheses in that the cobalt chrome alloy heads and cups (Metasul) are of the highest precision with controlled loose fitting. These allow low friction and low wear of approximately 5 micrometers per year. It is anticipated that debris related late loosening will be avoided by the use of this design. Approximately 30,000 Metasul hearings have been produced. The first 110 Weber metal on metal hip implants have been analyzed. No adverse effects from the wear of the new metal on metal components have been noted in this series.
作者与瑞士苏尔寿医疗技术有限公司共同研发了新一代金属对金属承重全髋关节。该设计与麦基型假体不同，其钴铬合金股骨头和髋臼（Metasul）具有最高精度且配合间隙可控。这些特性使得摩擦力低，每年磨损约5微米。预计采用这种设计可避免与碎屑相关的晚期松动。已生产了约30000个Metasul髋关节。对首批110个韦伯金属对金属髋关节植入物进行了分析。在该系列中未发现新的金属对金属部件磨损产生的不良影响。
