The method suggested is based on direct fracture
toughness determination using very small specimens, at the liquid nitrogen temperature.
Such fractures reflect the location, direction and magnitude of the force delivered, although the fine points of direct fracture
morphology are largely random.
At anthropometric measurements it became clear, that hematoma at primary fractures as against refractures, is located not only on a place of direct fractures
, but also a little distally and proximally, in the intramuscular space.
