Osteoporosis is a multifactorial skeletal disorder characterized by reduced bone mass and deterioration of the micro-architecture of bone. These features predispose affected subjects to increased susceptibility to fractures. According to the World Health Organization, osteoporosis is diagnosed if the bone mineral density (BMD) is 2.5 standard-deviations below the mean peak value in young adults of the same ethnicity and sex (T-score less than 2.5). The “gold standard” for measuring BMD is dual-energy X-ray absorptiometry (DEXA). Other diagnostic modalities include computed tomography (CT), peripheral quantitative CT, and ultrasonography (which has not been shown to provide additional information about bone quality).
