Significance of adult pedestrian torso injury

The current paper uses data from two trauma registries to evaluate the significance of adult pedestrian torso injury relative to head and lower extremity injuries and to determine the relative importance of injuries to individual torso organs/structures. Analyses are conducted with and without adjusting for striking vehicle body type (car versus LTV). Although the incidence of torso injury is approximately 50% higher in pedestrians struck by LTVs than in those struck by cars, torso injury appears to be as an important contributor to the overall cost of pedestrian morbidity as is lower extremity injury. The most frequently injured torso organs/structures include the rib cage, lung & pleura, and liver. The results indicate a need for an increased focus on the prevention of torso injury in the design of pedestrian safety countermeasures.
