This author's development of metal/metal hip resurfacing began in 1989, with the first patient implantation in February 1991. In the first three years a pilot study identified optimum fixation as hydroxyapatite coated uncemented cups and cemented femoral components. From March 1994 hybrid fixed components have been used. These implants have generally been satisfactory with respect to fixation but high wear of the bearing, metallosis and osteolysis have been seen with some components inserted during 1996, a period during which the metal microstructure was altered by the heat processes, hot isostatic pressing and solution heat treatment. The Birmingham Hip Resurfacing was developed taking account of experience with earlier resurfacing designs. This implant employs hybrid fixation with a porous ingrowth acetabular component and has an as-cast metal microstructure having had no post casting heat treatments. During the past 4 years the author has performed over 1,000 Birmingham Hip Resurfacingís with a total failure rate of less than 1.0%.
这位作者对金属/金属髋关节表面置换的研究始于1989年，1991年2月进行了首例患者植入。在最初的三年里，一项试点研究确定最佳固定方式为羟基磷灰石涂层非骨水泥髋臼杯和骨水泥股骨部件。自1994年3月起开始使用混合固定部件。这些植入物在固定方面总体令人满意，但对于1996年期间植入的一些部件，出现了轴承高磨损、金属沉着症和骨溶解现象，在此期间，金属微观结构因热加工、热等静压和固溶热处理而发生了改变。伯明翰髋关节表面置换术是在借鉴早期表面置换设计经验的基础上开发的。该植入物采用混合固定方式，髋臼部件为多孔长入型，其金属微观结构为铸造态，未进行铸造后热处理。在过去4年里，作者已实施了1000多例伯明翰髋关节表面置换术，总失败率低于1.0%。
