Because bone density can vary from one location in your body to another, a measurement taken at your heel usually isn't as accurate a predictor of fracture risk as a measurement taken at your spine or hip. Other terms used for bone density are bone mineral density (BMD) and bone mass. The fracture rates go up steeply with age, so any test that is closely related to age will be able to predict that an older person has more fractures than a young person. Together, the data reported here suggest that interspecies differences are likely to be found in other clinical and experimental bone parameters and should therefore be considered when choosing an appropriate animal model for bone research. Neither one of these scores can predict the fracture risk unless you also know the age. Differences in metapodia are also a result of physiology. The lower bone density test results, the lower your total bone density, indicating osteopenia or osteoporosis. This is due to differences in the standard deviations of the young populations.
