Outline of Final Research Achievements

By using Raman spectroscopy, we were able to understand the changes in structure and microstructure of bone samples due to the effects of osteonecrosis, and in particular the loss of mineralization and the changes in the composition of the bone collagen. These information were obtained by samples acquired from patients, and we were able to notice differences in osteonecrosis caused by alcohol and osteonecrosis caused by the assumption of steroids. Overall, Raman spectroscopy proved to be a powerful tool in the study of human bone, able to assess the quality of both the mineral and the organic fraction. Moreover, Raman spectroscopy could be used as an imaging tool, giving accurate chemical maps of the structure and composition of large areas of bone.
