Osteoporosis is a bone disorder characterized by low bone density, impaired bone architecture, and compromised bone strength that predisposes people to increased fracture risk.

Osteoporosis is a major health concern worldwide and for many Americans 50 years of age and older. The prevalence of osteoporosis rises dramatically with age. It has been estimated that the risk for fracture doubles every 7 or 8 years after 50 years of age.

Any fracture besides those of the fingers, toes, face, and skull can be due to osteoporosis. The majority of osteoporotic-related fractures are considered low trauma due to a fall from standing height or less or with minimal to no trauma; however, high-trauma nonspinal fractures are also more common in the elderly with osteoporosis.

Osteoporotic fractures contribute to increased costs and increased morbidity and mortality. Fractures of the hip and spine have been associated with reduced rates of survival.
