Increased hip-fracture incidence in the county of Osterg?tland, Sweden, 1940-1986, with forecasts up to the year 2000: an epidemiological study.

The incidence of hip fractures in the county of Osterg?tland in Sweden has increased dramatically from 1940 to 1986, mainly due to an increase in age-specific incidence of trochanteric fractures. The increase is most pronounced in people over 80 but is present even in age groups down to 50 years. If the age-specific incidence rates continue to increase, and the population of the elderly grows in accordance with the forecast, there will be 70% more hip fractures in the year 2000 than in 1985.
