Osteoporosis in men

Osteoporosis is characterized by a reduction in bone density, associated with skeletal fragility and an increased risk of fracture after minimal trauma. Although osteoporosis is generally considered to be a condition affecting post-menopausal women, it is now clear that substantial bone loss occurs with advancing age in men, such that up to 20% of symptomatic vertebral fractures and 30% of hip fractures occur in men. This chapter highlights the incidence and prevalence of osteoporotic fractures in men and reviews the associated morbidity, excess mortality and health and social service expenditure. The determinants of peak bone mass and bone loss in men are discussed, as is the pathogenesis of osteoporosis and vertebral and hip fractures. The criteria for the diagnosis of osteoporosis in men are reviewed, together with the most appropriate investigations for secondary osteoporosis. The management of osteoporosis in men is also discussed, highlighting the most appropriate treatment options.
