Analysis of pedestrian injuries in traffic accidents (2)--Especially on leg injury.
A deep case study on 118 pedestrians struck to fronts of vehicles or vehicle derivatives was carried out. In this paper we investigated a leg injury which occurs the most frequently in a vehicle-pedestrian collision. The data obtained from the case study were compared with those of autopsied cases. Influence of impact speed and point, and of an accident pattern were considered. The leg injury showed higher AIS (Abbreviated Injury Scale) than that of the arm injury caused by direct impact against the front exterior of vehicles. The impact speed and ISS (Injury Severity Score) showed strong correlation, but the former and AIS did not show significant correlation. The higher impact speed and the run-over are likely to cause a bilateral leg fracture.
