Objective: the computational analysis of digitized hip densitometric DXA images to determining if this type of images are useful for the optical-fractal textural analysis of bone, and, to differentiate better among populations with normal, osteopenic or osteoporótic bone mineral density (BMD) levels.

Material and methods: DXA densitometric hip images of 18 patients with normal BMD, 16 patients with osteopenic BMD levels and 16 patients with osteoporotic BMD levels were selected. Morphological, biomechanical and texturalfractal analyses of these images were carried out by means of Q-Bone® software.

Results: the analyzed morphological and biomechanical variables give complementary and discriminating information between the referred groups. Nevertheless, the unidirectional and multidirectional fractal textural analysis give only a little additional information, although when associated to optical variables (luminic density) seem to add a greater capacity of differentiation between groups of patients with normal and pathological BMD.
