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.
