Abstract. The article describes in detail a method of finite elementary models of human long bones using a software package Mimics.
Algorithm for creating realistic models of elementary-course of long bones examined by the example of constructing a model of the tibia. A computer model was created based on the homographic study nine legs in 8 male patients aged 23 to 54 years with no signs of bone pathologic. Creating realistic models was to use computer tomography of limb segments and, based on the numbers of Hounsfield, a partition on the types of bone: compact , and the spongy medullar canal. The models assigned anisotropic properties. In the software environment of ANSYS models showed excellent performance. With the help of realistic finite-elementary models of human long bones can be carried out computer simulations to calculate the optimal system of fixation of bone fragments in fractures of bones based on the definition of critical displacements and strains in bone tissue, and in the metal structures of fixation devices.

Keywords: long bones, computers design.
