Sch�delsch�sse bei Tr�gern milit�rischer Schutzhelme ? Allgemeines sowie Experimente und Beobachtungen zur Biomechanik und Wundmorphologie

Abstract

With respect to wound ballistics, the situation is different if the person wearing a military helmet suffers head injuries from a bullet. The mechanisms of injury were investigated in four experimental series and supplemented by a case history. The study showed surprising results: in the majority of cases, the helmet does not protect the wearer, but instead intensifies the damage caused by the bullet. The reasons for this phenomena are changes in the stability of the projectile and deformation of or damage to the bullet. All of these mechanisms result in the bullet striking the tissue with higher energy. In this investigation, Kevlar helmets were also tested, which are not penetrated by 9 X 19 mm parabellum bullets. Even so, however, severe injuries of the skull and brain can occur because the projectile causes intensified impressions on the skull under the helmet and, in addition, an acceleration of the head.

Potential Biomarkers in Experimental Animal Models for Traumatic Brain Injury

“…PBI is a more severe form of TBI caused by skull fractures from sharp objects or gunshot wounds. CHI is more commonly observed in individuals involved in sports or military services and caused by direct impact on the face, head, neck, or other parts of the body and by projectiles or bullets affecting the helmet [ 9 , 10 , 11 , 12 ]. Different types of CHI include contusion, diffuse axonal injury, concussion, and intracranial hematomas such as subdural hematoma, epidural hematoma, intra-parenchymal hemorrhage, or subarachnoid hemorrhage [ 13 ].…”
