To estimate the incidence of fracture of the proximal end of the femur in people aged 50 years or older living in the Quebec area in 1971, 1976 and 1981 we determined the number of admissions for such fractures to the 15 acute care hospitals in the region. From 1971 to 1981 the number of fractures increased by 71%; the increases for those aged 75 to 84 years and 85 years or over were 98% and 118% respectively. The variation is only partly explained by changes in sex and age distribution of the population; the incidence rates also increased. Among men aged 75 to 84 years the incidence rate per 1000 person-years rose from 2.63 in 1971 to 5.22 in 1981, an increase of 98%; the corresponding figures for men aged 85 years or more were 9.76 and 16.91, an increase of 73%. Among women aged 75 to 84 years the rate rose from 7.28 to 8.81, an increase of 21%; the corresponding figures for women aged 85 years or more were 20.40 and 24.27, an increase of 21% and 19% respectively.
为了估算1971年、1976年和1981年居住在魁北克地区的50岁及以上人群中股骨近端骨折的发病率，我们确定了该地区15家急症医院此类骨折的住院人数。从1971年到1981年，骨折数量增加了71%；75至84岁人群和85岁及以上人群的骨折数量分别增加了98%和118%。这种变化仅部分归因于人口性别和年龄分布的改变；发病率也有所上升。在75至84岁的男性中，每1000人年的发病率从1971年的2.63上升到1981年的5.22，增长了98%；85岁及以上男性的相应数字分别为9.76和16.91，增长了73%。在75至84岁的女性中，发病率从7.28上升到8.81，增长了21%；85岁及以上女性的相应数字分别为20.40和24.27，分别增长了21%和19%。
