Mechanism of injury (MOI),or kinematics,involves the action of forces on the human body and their effects.Motor vehicle collisions (MVCs)account for a high degree of blunt trauma.In the case of an adult trauma victim who is the driver in a head-on MVC at high speed,where the head hits the windshield and the chest impacts the steering wheel,what is the MOI and description of the possible injuries?

Question

Quizplus · Accepted Answer

During an MVC,actually three collisions occur.The first collision is that of a car into another object.The second collision is the impact of the occupant's body on the vehicle's interior.The third collision occurs when an internal body structure hits a rigid bony surface.A coup-contrecoup injury of the brain,for example,is the result of an acceleration force to one area of the brain and a deceleration force to an opposite area.The blunt trauma injury results from a combination of forces,such as acceleration and deceleration,and may not result in a break of the skin.
