The use of hip arthroplasties is evidently increasing, but there are few published data on the incidence in young patients.
We used data on total and resurfacing hip arthroplasties (THAs and RHAs) from the Finnish Arthroplasty Register and population data from Statistics Finland to analyze the incidences of THA and RHA in patients aged 30-59 years in Finland, for the period 1980 through 2007.
The combined incidences of THAs and RHAs among 30- to 59-year-old inhabitants increased from 9.5 per 10(5) inhabitants in 1980 to 61 per 10(5) inhabitants in 2007. Initially, the incidence of THA was higher in women than men, but since the mid-90s the incidences were similar. The incidence increased in all age groups studied (30-39, 40-49, and 50-59 years) but the increase was 6-fold and 36-fold higher in the latter two groups than in the first. The incidence of THA was constant; the increased incidence of overall hip arthroplasty was due to the increasing number of RHAs performed.
We have found a steady increase in the incidence of hip arthroplasty in patients with primary hip osteoarthritis in Finland, with an accelerating trend in the past decade, due to an increase in the incidence of RHA. As the incidence of hip osteoarthritis has not increased, the indications for hip arthroplasty appear to have become broader.
髋关节置换术的应用明显增加，但在年轻患者中的发病率数据较少。
我们使用芬兰髋关节置换登记处的数据和芬兰统计局的人口数据，分析了 1980 年至 2007 年期间芬兰 30-59 岁人群全髋关节置换术和表面髋关节置换术（THA 和 RHA）的发病率。
30-59 岁居民中 THA 和 RHA 的综合发病率从 1980 年的每 10 万居民 9.5 例增加到 2007 年的每 10 万居民 61 例。最初，女性 THA 的发病率高于男性，但自 90 年代中期以来，发病率相似。所有研究年龄组（30-39、40-49 和 50-59 岁）的发病率均有所增加，但后两个年龄组的增加幅度是第一个年龄组的 6 倍和 36 倍。THA 的发病率保持不变；全髋关节置换术发病率的增加是由于 RHA 数量的增加。
我们发现芬兰原发性髋关节骨关节炎患者髋关节置换术的发病率稳步上升，过去十年呈加速趋势，这是由于 RHA 的发病率增加所致。由于髋关节骨关节炎的发病率没有增加，髋关节置换术的适应证似乎已经扩大。
