Objective: to estimate the changes of effective stresses (by Mises) at three types of loads (axial, lateral and twisting) for various types of intramedullary nails synthesizing modeled fractures of A1; A3; B2 types at the level of femur bone middle third. Material and Methods. To solve the preclinical tasks computer simulation of biomechanical systems bone-fixing pin and method of finite elements were employed. Results. The nails developed by SarNIITO excel ChM and Fixion rods in stress-deformed condition, fatigue strength and stability of fixation of the examined types of fractures parameters of 12- 23%. Conclusion. The mechanical characteristics of SarNIITO nails proved to be of clinical use and may be recommended for patients with femur bone diaphysis fractures.
