[Micromorphology of torsional bone fractures]

Characteristic microlesions can be found along the torsion fractures of long bones related to special anatomy of compact tissue: Torsion severs singular lamellae of broken osteons along the longitudinal fracture lines. Exposed bone bridges are partially broken and haversian canaliculi longitudinally opened among severed lamellae. Torsion mechanism of the bone injury can be estimated and reconstructed by SEM with sufficient certainty. An expert can be more conclusive about the body fall or flight in the moment of injury or collision. Evidence of rotation movement can be helpful in explaining secondary injuries. A more perfect medical opinion can help to more satisfactory elucidation and evaluation of accident conditions by the court.
