[Correlation between microhardness and X-ray transparency of the proximal portion of the human femur].
In order to be able to evaluate the mechanical properties of cortical and sub-cortical bone from a radiologic acquisition, the authors have researched a link between the X-rays transparency of bone and its hardness. A device for measuring hardness has been developed which allows an almost punctual evaluation of the mechanic value of bone. This value has been compared with X-rays transparency of the studied point. The link found between these two variables on 80 measures was strong, with signification less than 0.001.
