Abstract
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.
Résumé
L’incidence des fractures de la hanche a été souvent étudiée mais il persiste des doutes au sujet de l’accroissement avec l’âge. La proportion des fractures trochantériennes , variable, a été considéré en augmentation. Nous avons étudié 1730 cas enregistrés prospectivement de 1998 à 2003 en relevant l’incidence de l’âge et du sexe pour les factures intra-capsulaires et les fractures trochantériennes. L’incidence des fractures de la hanche chez les femmes de plus de 50 ans était de 1263/100 000 et pour les hommes de 452/100 000. La proportion de fractures trochantériennes était de 38% pour les femmes et de 41% pour les hommes. Il n’y avait pas de différence significative dans la proportion de fractures trochantériennes ni entre les sexes ni au sein d’un même sexe et la proportion n’excédait pas 50% dans chaque groupe. Ces chiffres confirment la grande incidence des fractures de la hanche en Norvège mais ne montrent pas d’augmentation. La proportion des fractures trochantériennes semble, elle aussi, stable.
