Abstract
Neck fracture is a major cause of death in traffic accidents and this injury pattern occurred normally in a frontal collision or overturn process. This study investigates a case of neck fracture from a low speed collision. In this case examined, the passenger in the front seat of the car was pulled back and did not have the seat belt on. As the vehicle slipped on a frozen road surface in a downward hill and crashed into the shoulder of the road at low speed. But strangely, even though his neck is fracture there were not any collision marks on interior of the car. This study applied computer simulation to analyze this case and we found out that the upper part of the person was rotated and raised at the time of collision and his neck was fully bent by interference with roof and we also know that the seat belt did not resist the passenger who pulled back his seat.
Key Words: madymo, low speed, collision, neck injury
