Abstracts:
The effective modulus of elasticity is a key parameter that characterizes the stiffness of a material and its ability to resist deformation. It is known that the modulus of elasticity of bone is strongly correlated with its structural characteristics, such as mineral density and porosity. Many research groups have focused on studying the elastic properties of cancellous bone using uniaxial compression experiments. Given the difficulties associated with conducting in-situ experiments on human bones, studies of the mechanical properties of cancellous bone are often performed on bovine specimens. It should be noted that the results obtained by different experts and scientific groups can vary significantly, which emphasizes the need to analyze the interexpert and interlaboratory reliability of such studies. In this paper, the study of inter-expert reliability in calculating the effective modulus of elasticity of bovine cancellous bone and in constructing regression relationships linking it to structural properties is carried out. For this purpose, a number of experiments on uniaxial compression of spongy bone samples were carried out, and the volume, mineral density and porosity of the studied samples were determined. Calculation of elasticity moduli and assessment of bone structural properties were performed by different experts. As a result of analyzing the results, we were able to obtain sufficiently high reliability values for the calculation of the effective modulus of elasticity of bone tissue by different experts and their construction of dependencies of this index on the structural properties of bone (porosity, mineral density, bulk density).
