[Epidemiology of osteoporotic fractures in Switzerland].

Fractures occurring after 50 years of age are among the leading causes of hospitalizations in Switzerland. At the age of 50 years, in Switzerland, the remaining lifetime probability of suffering an osteoporotic fracture is 51% and 20% for women and men, respectively, i.e. every other woman and every fifth man. According to the demographic projection scenarios, the number of elderly aged 65 years or more will have doubled by year 2050. In the absence of targeted interventions, the considerable human, social, and economic burden represented by osteoporotic fractures should increase by the same order of magnitude. With FRAX (fracture risk assessment tool), validated for Switzerland in tight collaboration with the World Heath Organization, the individual probability of fracture during the next 10 years can be predicted.
