[Morphological features of gunshot injuries of the cranial bones].

[Article in Russian]


Morphological characteristics of gunshot injuries of the cranial dome bones depend on bullet speed and are determined by various mechanisms of the harmful action. A contusion action of the bullet is characterized by disruption of the bone tissue with formation of linear or incomplete fracture. A wedged impact is accompanied with disruption of bone structures with formation of depressed or comminuted fractures due to radial dislocation of the fragments. A perforative impact produces a hole defect the shape of which depends on bullet speed. A bursting impact of the bullet causes disruption of the bone tissue outside the bullet defect as a result of an additional radial effect of high pressure of the air wave reaching in the wounds inflicted by high-speed bullets the effect of the hydrodynamic shock in the spongy layer of the flat bone. Resultant morphological manifestations are aggravated by damage caused by hydrodynamic shock coming from the cranial cavity.
