    In the research work on acceleration-deceleration fractures, 25 cadavers of patients of the average age of 68 were used. The death of the patients was notcaused by injury. All ethical and moral ... principles were fully observed. Individual blunt blows on non-fixated heads of the cadavers selected were simulated by means of a remote control pneumatic piston. The pressure in the air reservoir of the cylinder was from 6.5 to 7 bars per single movement of the piston, which could be regulated with valve adjustment. The selection of areas in which the experiments were carried out depended on those predominantly exposed to injury: forehead, occiput and temples, which were divided due to the position of the fossa cranii media, according to the actionof force upon the temporal-frontal, temporal-parietal and temporal-occipital areas. During experimental work, the deformations of the scull were measured with a sensor (a device used for measuring deformations), which was connected with the piston and fixed to the monitor, as well as by means of a computer and the device for the visual presentation of deformations(CAT). Fractures of the base in the fossae anterior and posterior were the results of blows on the forehead and the occiput. Blows on the occiput led to two more fractures of the scull. Fissures are sagittal and partly, in the fossa cranii posterior, ring-shaped. The number of fractures inboth fossae is higher if the blows comes from the opposite direction. A simular relation can be found in fractures of the sinuses, as well as those which could cause damage to the cranial nerves. (Abstract truncated at 2000 characters)
