In the modern world, taking into account the active lifestyle of people, the dynamics of growth of complex fractures is observed. Their treatment is associated with rigid fixation of fragments with plates and screws, that is, with the help of osteosynthesis. In the surgical operating room during osteosynthesis is not possible to use auxiliary tools, which can be used to fix the screw with the required screw-in force. As a result, the screw breaks either during surgery or during further operation. This can be avoided by examining the stress-strain state of the screw head for osteosynthesis. By simulating the screw turning process, it is possible to determine the maximum stresses appearing in the screw heads with different profiles, and to choose or develop the profile of the recess under the key, which will be optimal in terms of stress-strain state and manufacturability .
