Low-Trauma Pelvic Fractures in Elderly Finns in 1970–2013

Low-trauma fractures of elderly persons are a major public health problem. However, epidemiologic knowledge on their fresh secular trends is scarce. Trends in the number and incidence (per 100,000 persons) of low-trauma fractures of the pelvic ring among older Finns were assessed by taking into account individuals 80-year-old or older who were admitted to Finnish hospitals for primary treatment of such injury in 1970–2013. The number and age-adjusted incidence of these fractures increased considerably between 1970 and 2013, from 33 (number) and 73 (incidence) in 1970 to 1055 and 364 in 2013. The age-specific incidence of fracture also increased in all age groups (80–84, 85–89, and 90–) of women and men during the entire study period. If the fracture incidence continues to rise at the same rates as in 1970–2013 and the size of the 80-year-old or older population of Finland increases as predicted (87 % by the year 2030), the number low-trauma pelvic fractures in this population will be 2.4 times higher in the year 2030 (2550 fractures) than it was in 2013 (1055 fractures). The number of low-trauma fractures of the pelvis among Finns 80 years of age or older has risen sharply between 1970 and 2013—with a rate that cannot be explained merely by demographic changes. Further studies are urgently needed to better assess the reasons for the rise and possibilities for fracture prevention.
