在1969年至1980年期间，明尼苏达州奥姆斯特德县的居民共进行了381例全髋关节置换术，发生率（经性别和年龄调整）为44.6/10万人年。发病率随年龄增长而上升，女性高于男性，该县城市居民高于农村居民。如果我们假设奥姆斯特德县的经验在医学上是最佳的，并将其应用于1980年的美国人口，我们计算出每年全国需要超过10万例全髋关节置换术，远高于目前的实际数字。如果每年实际进行全髋关节置换术的计算数量，将需要超过140万个住院日，每年的直接医疗费用可能超过10亿美元。（《新英格兰医学杂志》1982年; 307：1242-5）
Three hundred eighty-one total hip arthroplasties were performed on residents of Olmsted County, Minnesota, during the period from 1969 to 1980, for a rate (adjusted for sex and age) of 44.6 per 100,000 person-years. Rates rose with age, were higher for women than men, and were higher among urban than rural residents of the county. If we assume that the Olmsted County experience is medically optimal and apply it to the 1980 United States population, we calculate a national requirement of over 100,000 total hip arthroplasties per year, well above the current actual figure. If this calculated number of total hip arthroplasties were actually performed each year, over 1.4 million hospital days would be required, and direct medical costs would probably exceed $1 billion annually.
