[Fatal craniocerebral trauma in a young child. I: Forensic documentation, model generation and geometric impact...

The aim of forensic biomechanics is the reconstruction of traumatic events based on the pathological findings in the victim's morphology and on the traces and shapes of the traumatizing tools. The introduction of Streifenlichttopometrie into forensic science enables 3-dimensional and proportionally accurate documentation of the victim's body and injuring agent with submillimeter precision. The advantages of this method of documentation are the possibilities of producing animated models which correspond exactly to the body's shape and injury topography, and of ascertaining the physical parameters (centers of mass, moments of inertia) of the various body parts and the geometrical impact conditions for the reconstruction of the injury dynamics. This way of proceeding thus enables more precise models than hitherto possible for kinetic and dynamic reconstruction. In the case of an infant who was fatally injured by a wooden sculpture the generation and application of computer aided 3-dimensional reconstruction models are shown.
