We report the incidence of total hip replacements performed in Iceland between 1982 and 1996. During this period, 3,403 hip arthroplasties were done. The annual number of procedures increased from 94 hips in 1982 to 323 hips in 1996. Annual rates of total hip replacements due to primary osteoarthrosis per 10(5) inhabitants were 68 in 1982-1986, 90 in 1987-1991, and 114 in 1992-1996. In the years 1992-1996, the age-standardized incidence of total hip replacements for primary osteoarthrosis was 3/10(5) among patients younger than 39 years of age, while it was 621/10(5) among those 70-79 years of age. The mean age at surgery for primary osteoarthrosis was 69 years in both men and women. Incidence rates in various countries are difficult to compare, but by using age-standardized data and correction for differences in population structures between Iceland and Sweden, we find that the incidence of total hip replacement for primary osteoarthrosis of the hip is at least 50% higher in Iceland than in Sweden. This difference is consistent with the higher prevalence of hip osteoarthrosis observed in Iceland than in Sweden.
我们报告了1982年至1996年间冰岛全髋关节置换术的发生率。在此期间，共进行了3403例髋关节置换术。手术例数从1982年的94例增加到1996年的323例。1982 - 1986年、1987 - 1991年以及1992 - 1996年，每10万居民中因原发性骨关节炎进行全髋关节置换术的年发生率分别为68例、90例和114例。在1992 - 1996年期间，原发性骨关节炎患者中，年龄标准化的全髋关节置换术发生率在39岁以下患者中为3/10万，而在70 - 79岁患者中为621/10万。原发性骨关节炎患者手术时的平均年龄，男性和女性均为69岁。不同国家的发病率难以比较，但通过使用年龄标准化数据并校正冰岛和瑞典人口结构差异，我们发现冰岛原发性髋关节骨关节炎的全髋关节置换术发生率比瑞典至少高50%。这一差异与冰岛观察到的髋关节骨关节炎患病率高于瑞典一致。
