About Osteoporosis

According to the National Osteoporosis Foundation, the number of women of menopausal age who have osteoporosis or are at risk for developing the disease will increase from almost 30 million in 2002 to nearly 41 million by 2020. Osteoporosis causes approximately 1.5 million fractures each year in the United States alone, and the risk of fracture significantly increases in women usually after age 50. Non-vertebral fractures are more common than vertebral fractures and account for an estimated 300,000 hip and 250,000 wrist fractures, in addition to an estimated 250,000 fractures at other non- vertebral sites such as the clavicle, humerus, pelvis and leg.
