Rotational falls occur when a horse falls in such a manner as to somersault before landing on its back. It is of particular concern in the sport of eventing, especially in the cross-country phase of the competition. These falls can cause grave injuries and in the past have resulted in fatalities; such fatalities have spiked in recent years, prompting investigations and movements worldwide to increase the safety for participants.
Eventing is a three-phase competition consisting of dressage, cross-country, and show jumping. Riders worldwide compete in eventing, up to an Olympic level.
