Rotational Falls

 

This video gives a visual demonstration of what frangible pins were designed to prevent - a rotational fall, in which the horse, unable to clear the fence, essentially "trips" and flips over the fence. Both horse and rider were uninjured after this particular episode, but for many who suffer these kinds of falls, that is not the case. These types of falls often cause spinal damage and can be fatal for both horse and rider. Frangible pins were developed to prevent such falls from happening.
