Front-end collisions resulting in airbag release can cause significant physical injuries. The force of the bag inflating against the body protects the person from smashing into the dashboard or going out the front window.
But as Newton’s third law of motion states, For every action, there is an equal and opposite reaction. This means that for every force there is a reaction force that is equal in size but in the opposite direction.
The transfer of force during the car crash and air bag release can result in a traumatic injury to the otherwise unprotected body. The most common airbag-related injuries are to the hip, thigh, and knee. In fact almost half (49.5 per cent) of airbag injuries affect these areas. More than one-third of the injuries (38.4 per cent) are to the foot and ankle.
Fractures, dislocations, and torn ligaments affecting the midfoot are common. And height is a factor. Being short (usually less than four feet, six inches) does increase the number of ankle and foot injuries. If the foot is not planted firmly on the car floor, the unprotected, unstabilized area takes a significant hit.
