Abstract
Background. The solution of the expert task to determine the circumstances of trauma formation, only on the basis of forensic medical data is not always possible. In some cases, the use of mathematical calculations for dynamics analysis of the accident allows to reconstruct the conditions of mechanical trauma formation.
Case presentation: On the example of expert observation (fatal fall accident) the effectiveness of biomechanical (mathematical) analysis within the framework of forensic complex medical dynamic-kinematic expertise in reconstructing the circumstances of mechanical trauma is demonstrated. With the help of the constructed mathematical model it was determined on which part of the body the victim should have fallen in case of spontaneous fall, i.e. in the absence of additional external force impact. Comparison of actual medical data with calculated data allowed us to conclude that before the fall the victim's body was given an additional initial velocity.
Conclusion: The expert case described in this paper is an example of the application of computational experiment as a digital toolkit for objective expert selection of one of the alternative versions of mechanical trauma formation.
Keywords: expert case of a fall accident, situational study, accident biomechanics, mathematical model, complex medical dynamics-kinematics expertise.
