Analysis was conducted on calcific deposits from 5 patients with calcific periarthritis. These calcific deposits were dried, immersed in hydrazine, or heated to 1000 degrees C for 1 hour, to prepare 3 kinds of samples. The samples were classified as dried samples, hydrazine-deproteinated samples, or as heated samples. All samples were analyzed by X-ray diffraction (XRD). Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy (Raman), and by electron probe microanalysis (EPMA). Although the XRD patterns of the dried samples and of the deproteinated samples were similar to that of hydroxyapatite (HAp), it was still unclear whether or not the calcific deposits were HAp. FTIR then revealed that the dried samples contained carbonate. Raman showed that the dried samples and the deproteinated samples do not have an OH-group. The dried samples were then heated to 1000 degrees C for one hour and analyzed by all 4 methods. The heated samples were found to be HAp. From these results, the calcific deposits from the 5 patients with calcific periarthritis were found to be carbonate apatite: Ca10-x-y/2 (PO4)6-x (CO3) x (OH) 2-y (CO3)y/2.nH2O.
