FTIR spectra of the healthy bone (HB) and bone with a stress fracture (SF) measured in the fingerprint region (1800–500 cm−1). Several absorption bands of lipids, proteins (collagen type I), and minerals (phosphates and carbonates) were observed. Each spectrum corresponds to the average of five samples of the HB and 11 samples of the bone with an SF, which was measured three times.
