 Background Osteoporotic hip fractures exact an immense human and economic toll and therefore constitute a major public health problem. Because their incidence increases exponentially with age in both men and women, they will impose an increasing burden in the near future as the population continues to age throughout the world. In addition to the direct costs of fractures hospitalisation and rehabilitation, the subsequent risks of death, functional impairment, dependency, and institutionalization are increased as compared to same-age individuals without fractures. Low BMD is the main risk factor for hip fracture and is generally measured using DXA, which is the reference standard.
