We work in the consolidation of previous studies performed by us concerning microdamage developments in bones with use of conventional basic fuchsin staining, in which we stated that age and gamma radiation had a direct influence on the increase in the generation and growth of microfractures, to provoke the fracture of bones by fatigue by means of a novel theoretical model based on a concept called characteristic length. The mentioned conventional staining technique has the disadvantage of being invasive, destructive, two-dimensional (2-D), and tedious. For this reason, the aim of our current work was the use of a worldunique patented computed tomography device – TORATOM. With the use of precipitation barium sulfate process, we identified individual microcracks, which will be analysed in further studies to define better predictive models to understand and prevent fatigue fractures due to stress and fragility related to osteoporosis, which will be useful in developing new clinical approaches to the problem of osteoporosis.
