The incidence of hip fracture has been studied extensively, but there is still some doubt whether the age-specific incidence is increasing. The proportion of trochanteric fractures has varied and has also been said to be increasing. We studied data on 1,730 prospectively registered cases from 1998-2003 and computed age- and gender-specific incidence rates for intracapsular and trochanteric fractures. The incidence of hip fracture for women over 50 years was 1,263 and for men 452 per 100,000. The proportion of trochanteric fractures was 38% for women and 41% for men. There was no significant difference in the proportion of trochanteric fractures either between or within the genders, and the proportion did not exceed 50% in any age group. These findings confirm the high incidence of hip fracture in Norway but do not indicate any increase. The proportion of trochanteric fractures also seems to be stable.
髋部骨折的发病率已得到广泛研究,但特定年龄段的发病率是否正在上升仍存在一些疑问。转子间骨折的比例有所不同,也有人称其在增加。我们研究了1998年至2003年期间前瞻性登记的1730例病例的数据,并计算了囊内骨折和转子间骨折的年龄和性别特异性发病率。50岁以上女性髋部骨折的发病率为每10万人中有1263例,男性为452例。转子间骨折的比例女性为38%,男性为41%。性别之间或性别内部转子间骨折的比例均无显著差异,且在任何年龄组中该比例均未超过50%。这些发现证实了挪威髋部骨折的高发病率,但并未表明有任何增加。转子间骨折的比例似乎也很稳定。
