Morphological Findings in Hanging Deaths
Hejna, Petr ; Hottmar, Petr (advisor) ; Hirt, Miroslav (referee) ; Klír, Přemysl (referee)
Hanging is a form of ligature strangulation in which the force applied to the neck derives from the gravitational drag of the weight of the body. The furrow on the neck is mainly a postmortem phenomenon. To establish the intravital hanging, any inner neck structure injury indicating ligature mark intravitality is to be identified. The aim of this prospective autopsy study was to determine frequency of inner neck structure injuries in hanging with regard to the point of the ligature knot and the other victims' characteristics (body suspension, gender, age, weight). We tried to identify the mechanism of injury for the neck structures and determine, according to the obtained results, a possible specific or most characteristic inner neck injury in regard to the ligature knot location. This study also aimed to determine the frequency of Simon's bleedings in the lumbar region of the spinal column in cases of hanging. The authors prospectively studied 178 consecutive cases of hanging deaths. Fracture of throat skeleton was detected in 128 cases of hanging (72%). The hyoid bone fractures were indentified in 56 cases of hanging (31,5%). Horn thyroid cartilage fractures were found in 101 cases of hanging (56,8%). The occurrance of fractures of throat skeleton was independent of gender, age, weight and...
