Abstract: The biomechanical behaviour of trabecular bone depends not only on its microarchitecture but also on mineral density distribution. Bone mineral density distribution is coupled with mechanical properties of the tissue. In this preliminary study intratrabecular composition of individual trabeculae was investigated. The quantitative backscattered electron microscopy (qBSE) a method based on detection of electrons backscattered from surface layer of the specimen was employed to obtain high resolution images of the transverse sections of a trabecula. From acquired data the element map was created, organic (collagen fibres) to anorganic (hydroxyapatite) material ratio computed and collagen fibres orientation assessed. To conclude qBSE allows to obtain detail information about intratrabecular composition and material properties at the level of individual trabeculae.
