Notes:
Structure parameters of minerals in human bone, bioapatite, are very important forbiomaterials. In situ micro-XRD and Rietveld structure refinement were used to extract subtlestructure information of human ribs. Rietveld refinement testified that lattice parameters, crystallitesize and microstrain for cortical and cancellous bones were significant difference. Anisotropiccrystallite sizes of human rib showed preferential growth of apatite along c-axis and the gradedvariation at radial direction of bone axis. The variations of the subtle structures of bioapatite, such as,P occupancy and P-O2 bond length, as well as distortion index of P-O tetrahedron, demonstrated thetendency of mineralization and the content of CO32- in human ribs
