Spatial clusters of high incidence rates were found, with annual averages (per 100,000 inhabitants) varying from 154.4 to 572.2 and 77.3 to 231.5 for women and men, respectively. Geographic inequalities in the occurrence of hip fractures were also found.engGeographic information systemsHip fracturesOsteoporosisSpatial analysisSpatial clustersSpatial dependencyjournal article10.1007/s00198-008-0623-11433-2965
