A patient's relative risk for fracture doubles for each 10-12% decrease in bone densitometry.
Bone Mineral Density Measurements: The measurements of bone mineral density should be performed at the same site with the same technique.
change in bone density in percent =
= ((patient's current bone mineral density) - (patient's baseline bone mineral density)) / (patient's baseline bone mineral density) * 100%
If the current mineral density is less than the baseline value, then
relative risk of fracture compared to baseline =
= 2 ^ ((change in bone density in percent) / 10%)
The relative risk also increases with a history of fragility fractures after the age of 50.
