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.
Falls of the rider from the horse are common and can occur at any point in time, from training to the middle of a competition. Horse riding is described as a "hazardous pastime",[1] with a high level of injuries and in some cases, death. One large contributor to these fatality statistics is that of a rotational fall. "Between May 1997 and September 2007 25 rider deaths occurred around the world in the sport of Eventing",[2] 18 of these fatalities resulted from rotational falls.
A rotational fall is defined as when the "horse forward somersaults in the air before landing on its back.”[3] This often occurs as a result of the horse hitting the fence with its front legs while jumping. The possibility of a fall occurring can be increased by a variety of factors including; condition of ground, experience of rider, experience of horse, type of jump, undertaking of course prior to fall and/or position on the scoreboard.[3]
The cross country phase of eventing presents a course of obstacles that the horse and rider must navigate through to the finish line, these obstacles are solid and unforgiving (photos below show examples of jumps on a course). The jumps being solid "demands that a rider approach the jump at exactly the right speed, take off from the right angle and spot". Rotational falls are most likely to occur during cross country as the fall occurs when the "horse hits a solid fence either with its chest or upper forelegs".[4] This becomes increasingly likely the higher the jumps get.[4] Although historically, rotational falls were possible in the show jumping phase as rails used to be fixed to the wings that held them, in modern times the jumps are designed with cups holding the rails, allowing them to roll out and fall down if struck by the horse.
All sports and activities present unique risks (ranging from small to large scale possibilities) to the individual or team participating in them. Eventing is no different, it is considered a "high-risk equestrian sport".[3] Injuries to both horse and rider as a result of competition in Eventing have occurred throughout history and across the world, it is "a sport in which the vast majority of rider injuries are minor and insignificant, but in which the possibility of catastrophic results always exist".[5]
Although Eventing as a sport dates to 1902, it wasn't until 1999 that concerns of horse and rider safety emerged.[3] That year, there were five rider fatalities as a result of falls in the United Kingdom alone, four out of these five riders had a rotational fall by their horse leading to their death.[6][5] As a result of these fatalities, in April 2000 the Fédération Equestre Internationale (FEI) conducted "The International Eventing Safety Committee Report"[6] and recommended creating an FEI Annual Report[6] to cover a variety of subjects. Between 1997 and 2008, "at least 37 eventing riders have died as a result of injuries incurred while competing in the cross-country phase of eventing".[5] At least 25 of these deaths were as a result of a rotational fall. These deaths ranged in location (concentrations of deaths in the United States and United Kingdom) and level of competition (pony club, national or international competition).[5] However, some "top competitors, coaches and course designers argue that the sport's death and injury toll is most likely related to an influx of new riders to the sport",[7] suggesting a lack of experience increases the likelihood of suffering a fall.
The FEI conducted a statistic report on Eventing Risk Management, presenting statistics on competitions, starters, falls and injuries between 2006 and 2016. In 2006 there were a total of 13,660 starters, with 789 falls, of these falls 51 were classified as rotational horse falls and 12 were considered to result in the rider suffering serious injuries.[6] However, ten years later in 2016 there has been a significant increase (of 6261 riders) in starters to 19,921 riders, of these there were 1064 falls.[6] However, despite an increase in both competitors and overall falls only 30 of these were classified as rotational falls, and 5 riders were considered to result in the rider suffering serious injuries.[6] Comparing these rotational fall statistics across a ten-year expanse convey a clear decrease in rotational falls and rotational falls resulting in serious injury.
Horse riding is considered a dangerous sport. However, "while equestrian sports are considered to have a certain degree of risk associated with them, there are ways to make them safer".[8] Safety measures continue to be introduced to reduce these risks; these measures revolve around both the rider, the horse and course design.
The rules of competition as guided by the FEI and individually enforced by countries around the world with their own bodies drafting standards for riders state that all riders are required to wear "an accredited safety helmet during cross country competition".[9] These standards are reviewed and updated regularly by both the FEI and individual countries. For example, Equestrian Australia have introduced a new regulation, Helmet Tagging. This will "enable officials to more easily identify those helmets complying with standards",[10] all helmets must have a coloured tag on them visible to officials which conveys the helmet has been checked and complies to current standards.
Body protectors are pieces of equipment used by riders in many different types of riding; one particular type is the cross country phase of eventing. A body protector traditionally "is a foam filled vest to be worn over clothes".[11] It is designed to protect the upper body (ribs and spine) from serious injury if a fall occurs. The regulation of body protectors had been discussed by the National Eventing Committee (NEC) many times, however, "only by the end of 2006 did the NEC decide that body protectors would be compulsory".[9] Between 2000 and 2006 a study was conducted on body protectors in which riders were asked 'Were you wearing a back protector?', over 90% of riders "indicated that they were wearing one, despite there being no regulation of requiring this".[9]
In 2009 a new type of body protector was introduced, inflatable vests. The design is of "a gas canister, connected by a cord to the horse's saddle, is discharged when the cord is pulled during a fall, inflating the jacket in a fraction of a second".[12] This design has the potential to reduce the chance of fatality as a result of a rotational fall due to its design aiming to disperse the force of an impact "and reduce compression of the chest".[12]
Although there are less protective measures available for horses, one key technique used by riders to increase the safety of the course for the horse is greasing legs. Riders place grease on "a horse's front and hind legs to prevent trauma from the brush jumps, and if they hit an obstacle, they'll slide off it a little bit more".[13] This particularly assists in the prevention of rotational falls as it encourages the legs, even if they hit the jump to slide over, as opposed to be caught or left behind causing a possible trip or rotational fall.[citation needed]
The cross country course itself poses the largest risks to the horse and rider for experiencing a rotational fall, this is due to the uniquely solid nature of jumps on a cross country course (as opposed to collapsible fences on a show jumping course). Over the years there have been many discussions regarding methods and technologies available to improve the safety of a fence and the "breakability"[14] of a fence is at the centre of discussions. An "extreme version of maximising breakability would be just putting show jumps in a field",[14] however that has been criticised as it defeats the purpose of the challenge of the cross country phase as uniquely different from show jumping. Two key technological advances have been adopted improve the safety in the cross country phase of eventing to minimise the possibility of a rotational fall.
Frangible pins and mim clips are "pins and hinges that break and swing down if a horse hits it, reducing the chances of a fall for both rider and horse".[15] However, as this technology is relatively new they are still learning the 'in field' mechanisms of the pins and clips, "the important thing to remember is that a device is just a mechanical object that will do certain things under certain circumstances according to its design".[14] Statistics on the use of frangible pins demonstrate that "angles and impact factor in"[14] to the technical process of a pin or clip breaking allowing the jump to fall. The devices ensure that although "horse falls cannot be completely avoided... the use of frangible devices allows the fence to drop on contact therefore preventing a horse from falling".[16] The horse is more likely to trip and regain an upright position, as opposed to performing a full rotation. In commenting on the introduction of frangible pins to Australia in the Equestrian Australia 'Making Eventing Safer Fund', "dual Olympic medallist, course designer and coach Stuart Tinney" said "it's very exciting to be able to introduce more safer fences to Eventing".[16]
