A new, non-destructive protocol for the screening of in-vivo femoral heads retrievals is proposed; A grid is applied on the sample's surface dividing it in sectors examined through Raman spectroscopy and laser microscopy; Combining data and CAD modeling it's possible to create representative 3D models of the retrievals; The models provide fundamental information of topological, crystallographic, chemical, and micromechanical nature; Monoclinic volume fraction profiles, roughness values and residual stresses were non-destructively traced;
