AnnotationThis study is dedicated to mathematical formulation of the thermoelasticity problem for the biotechnical system ''tibia bone – TRKh plate – screws'' and its solution using the finite element method.Biomechanical research of biotechnical system is conducted at 10 different time stages. Evaluation of maximum values of equivalent stresses is shown that fixation stability of a segmental fracture is not disturbed.
