Characterization of the Biological Fingerprint and Identification of Associated Parameters in Stress Fractures by FTIR Spectroscopy

Figure 3

FTIR images in sections of healthy bone samples and bone samples with stress fracture. In all images, red color corresponds to the highest values and blue to the lowest values. Spatial distribution of the amount of collagen, as well as the matrix maturity, mineralization, carbonate substitution, acid phosphate substitution, and crystallinity ratios, was calculated from the FTIR spectra.
