Osteoporosis and Osteomalacia

Osteoporosis is a metabolic bone disorder characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to enhanced fragility and a consequent increase in fracture risk (1). Clinically, it is defined by evidence of osteopenia associated with a fracture, or history of fractures with minimal trauma. It is defined quantitatively as a bone mineral density (BMD) of less than 2.5 SD below the mean gender-matched maximal bone density (1).
