Osteoporosis, in which low bone mass and micro-structural deterioration of bone tissue lead to increased bone fragility, it is a chronic, progressive disease of multifactorial etiology. In the last 15 years, there has been a movement to base the management of osteoporosis not on the absolute BMD values but to rather consider the [[Fracture Risk Assessment (FRAX) Tool|risk for fracture]] risk in the futurePaskins Z, Ong T, Armstrong DJ. [https://academic.oup.com/ageing/article/49/3/329/5799034. Bringing osteoporosis up to date: time to address the identity crisis.] Age & Aging. 2020.. This was fuelled by the fact that most patients with a fragility fracture were not diagnosed with osteoporosis because their BMD did not meet the definition cut-off. Osteoporotic fractures lead to a significant decrease in [[Quality of Life|quality of life]], with increased morbidity, mortality, and disability. Over 50% of postmenopausal white women will have an osteoporotic-related [[fracture]]. Only 33% of senior women who have a hip fracture will be able to return to independence. In white men, the risk of an osteoporotic fracture is 20%, but the one-year mortality in men who have a [[Femoral Neck Hip Fracture|hip fracture]] is twice that of women. Black males and females have less osteoporosis than their white counterparts, but those diagnosed with osteoporosis have similar fracture risks. The [[Older People - An Introduction|aging]] of the American population is expected to triple the number of osteoporotic [[Fracture|fractures]].Joann L.
