Dynamic analysis of penetrating trauma.

摘要: BACKGROUND: Whereas considerable literature exists on the wounding mechanics of high velocity projectiles in military domain, there is a paucity such data from routinely encountered civilian population United States. This study was undertaken to develop methodology and determine dynamics penetrating trauma secondary low (200-300 m/sec). To demonstrate feasibility experimental protocol, two markedly different were chosen study. METHODS: Two discharged into human tissue simulant; one projectile smooth other expansion type. High-speed video photographic analysis synchronized trigger techniques used describe path during its travel within simulant. The temporal transient residual profiles demonstrating "wound involvement" computed. RESULTS: Results indicated stark contrast between cases. There ratio approximately three-to-one maximum wound involvement due penetration. Transient wave oscillations penetration perforation simulant demonstrated significant differences amplitudes time durations. In addition, injury potential. CONCLUSIONS: has provided an delineate dynamic behavior projectiles. fully quantify differentiate behaviors numerous available (with various combinations design, type equipment, discharge), further research this area clearly necessary. present protocol lends itself be systematically analyze all these behaviors. Quantified may assist clinical personnel management trauma.
