In this study the injury mechanisms of lower limb injuries are explained.Demands for car developments and dummy test work are also shown. The data has been derived from traffic accidents. These accidents were documented by a scientific team at the German Medical University of Hannover Accident Research Unit, during the 1985-1994 period. Out of a sample of 6,985 belted drivers in car crashes 2,605 of these persons with lower limb injuries were analyzed. Persons with pelvic fractures and isolated hip joint fractures were included. Pelvic fractures occur mainly in lateral impacts, especially with poles. It was also established that the injury risk for legs is different in various collision types such as frontal and lateral impacts. various collision types such as frontal and lateral impacts. Impacts of the vehicle side against a tree cause the most frequent and the most severe consequences. The different kinds and locations of injuries are shown related to the delta V (speed change) accident severity parameter. The impulse direction and the position of lateral force transmission are important for the resulting injury of the lower limb region. The kind of interior deformation is responsible for the kind of injury pattern, and the influence of intrusion is seen as an important factor.
