The short characteristics of the natural composite-bone is given. The parameters which characterised the bone mineral density (BMD) such as DEXA and QCT are presented. Furthermore, based upon the concept of cortical index CI, the characteristics of this one and short discussion about them - with possibility to predict the bone strength and fracture resistance - are made. Finally, the information about capability of the used fracture mechanics parameters such as K and delta to quantitative assessment of the fracture of cortical part of bone are presented.
