What estimates of bone loss and fracture risk can be made from BMD measurement by DXA

What estimates of bone loss and fracture risk can be made from BMD measurement by DXA?

T-score% Bone Loss aFracture Risk
–1122 times increased
–2244 times
–3368 times
–44816 times

a Note that one has to lose 30% of BMD to see osteopenia on a routine radiograph; this degree of loss suggests a T-score of –2.5.

Pearl: An older patient is more likely to fracture than a younger individual with the exact same T score.
