title: Incidence and characteristics of distal radial fractures in an urban population in The Netherlands.
abstract: The increasing incidence of distal radius fracture is thought to be due to the aging population. Surprisingly, some authors have reported a decrease in the incidence of distal radius fracture. Moreover, the type-specific incidence of distal radial fracture classified according to fracture severity is not well documented. The aim of this population-based study was to estimate the overall and type-specific incidences of distal radius fracture in a urban population in The Netherlands. During 2009, all persons aged ≥18 years old with an acute distal radius fracture in two hospitals in The Netherlands were prospectively registered. In 2009, the mid-year study population consisted of 245,559 inhabitants ≥18 years old. Fractures were categorized according to the AO classification. 494 patients with acute distal radius fractures were registered in the two participating hospitals during the 1-year study period. The overall incidence of distal radius fracture was 20 per 10,000 person-years. Among women, the incidence rate increased from the age of 50 and reached a peak of 124 per 10,000 person-years in women 80 years and older. Among men, the incidence rate was low until the age of 80 years and older, and reached a peak of 24 per 10,000 person-years. The incidence rate among women between 50 and 79 years was 54/10,000 person-years. Extra-articular AO type A fractures were most common among all age groups, comprising 50 % of all fractures (40 % in men and 53 % in women). The overall incidence rate of distal radius fracture was 20 per 10,000 person-years. This incidence increases with age for both women and men. A lower incidence rate among women 50-79 years of age was found than previously reported, which may indicate a declining incidence in this age group. Extra-articular AO type A fractures were the most common fracture types.
