Comparison of thoracic wall behavior in large animals and human cadavers submitted to an identical ballistic blunt thoracic trauma

Experimental study of the coupling parameters influencing the terminal effects of thoracic blunt ballistic impacts

“…Prat et al [11] studied the injuries observed on porcine models impacted by 40 mm less lethal projectiles, with kinetic energies of 100-160 J. The projectiles used by [11] were similar to those of the present study but they were not characterized.…”

“…The projectiles used by [11] were similar to those of the present study but they were not characterized. Analyzing the data of these authors [17] highlighted that Q 0 and the projectile design influence the skeletal motion and energy transfer.…”

“…Due to the use of dead animal tissues a caveat is necessary for the transposition of the raw results to the human body. However, the effects of the differences in the thoracic wall biomechanics [11] and the lack of muscular tone [8] or hypothetic tissue decomposition [7] should be the same for each specimen, so the modifications seen in the thoracic wall behavior depending on the mass/velocity/foam combinations should remain constant.…”

“…Prat et al [11] compared the thoracic wall response of living pigs and of human cadavers to blunt impacts. They underlined the need for living animal models in ballistic studies for providing reliable information on pathophysiological data.…”

“…By predicting the biomechanical responses of living animals based on surrogate tests animal experiments also provide insight for controlling the differences between living humans and surrogates when developing response and injury targets. Live porcine and PMHS responses to blunt impacts of LLKW have been analysed and compared using wound criteria by [11]. Sondé n et al [12] used Swedish landrace pigs, protected by a ceramid/aramid body armor which were shot with a standard 7.62-mm assault rifle; morphological injuries, cardiorespiratory and electroencephalogram changes as well as physical parameters were registered.…”
