Relative Fracture Risk Using Baseline Bone Densitometry Values

 

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.
