Incidence of osteoporotic fractures in Sado, Japan in 2010

Abstract

We conducted a survey of fracture incidences associated with senile osteoporosis in 2010 in Sado City, Niigata Prefecture, Japan, including compression vertebral fractures, hip fractures, distal radius fractures, and fractures of the proximal end of the humerus. We previously conducted a similar survey from 2004−2006 in Sado City. The purpose of the current study was to determine the incidence of osteoporotic fractures in Sado City in 2010 and to examine changes over time. We calculated the incidence of each fracture per 100,000 person-years based on the population of Sado City. Hip and vertebral fractures showed marked increases from 2004−2006, but a similar increase was not found from 2006−2010. The average age at injury increased in 2010 compared to 2004, except for fractures of the radius. Among the subjects with hip fractures, 14 % had a history of contralateral hip fracture. The percentage of patients taking medication for osteoporosis before injury was higher in 2010 compared with 2004, but these percentages were still only 7 and 13 % for those with subsequent hip and vertebral fractures, respectively.
