What estimates of bone loss and fracture risk can be made from BMD measurement by DXA?
|T-score||% Bone Loss a||Fracture Risk|
|–1||12||2 times increased|
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.
