Fragility fractures: clinical and therapeutic aspects

Abstract

Osteoporosis is the most important bone metabolic disorder characterized by reduction of bone mass and micro-architectural deterioration associated to an increased risk for fragility fractures. It involves millions of worldwide-dispersed individuals of both sexes and, consequently, the elevated morbidity and mortality of fractured subjects and the increased socio-economic costs suggest it must be faced as a major health problem. Thus, there is a need for either a precocious identification of subjects with fragile “bones” or the institution of specific diagnostic-therapeutical strategies. Improvement in bone pathophysiology knowledge, together with progress in pharmaceutical development has led to an opportunity for early identification and therapy of subjects at high risk of fragility fractures. In this review, we briefly describe the recent acquisitions in bone pathophysiology as well as in the anti-fracture drug development with a brief excursus on those already well established.
