Hoofcare@WEG Video: Inside the On-Site Veterinary Hospital

You can also view this video at this link, if it is not showing up here.

Note: Blog visitors may or may not see a video in this space. The video is provided by WKYT in Lexington, Kentucky and shows the temporary veterinary hospital built on the grounds of the Kentucky Horse Park for use during the World Equestrian Games.

Horses with serious injuries or illness have been transferred to Rood and Riddle Equine Hospital, which is only six miles away. Some eventing and endurance horses have been treated there but, as the video says, the injuries have been relatively minor and few in number so far. That's something to be thankful for!

The on-site hospital includes a veterinary podiatry unit provided by Rood and Riddle Equine Hospital in the form of a Stonewell Forge equine podiatry rig. (I learned last week from Brent Chidsey at Stonewell that this truck is not the same as a farrier truck, no matter how much it may look like one.) Dr Raul Bras DVM of Rood and Riddle, who is also a certified journeyman farrier with the American Farrier's Association has been on site several times. He speaks Spanish and has been able to assist some of the South American teams, who also found their way downtown to the Breeders Supply farrier store.

A special guest at the hospital was Professor Jean-Marie Denoix of France, who provided diagnostic ultrasound expertise at the hospital and spoke at the veterinary conference that preceded WEG.

All my knowledge of the hospital is secondhand, since security there is very tight and they won't allow media (that's me) in, hence the posting of this video, which may be as close as I ever get!

Racehorse Performance "Not Significantly Affected by Tendon Injury", According to Horse Trust Research

This horse has "bowed" it superficial digital flexor tendon; the tendon protrudes, or bows out, at the back of the leg. This is the most common debilitating tendon injury suffered by racehorses and requires a long layoff for recovery, although new treatments are shortening the time lost from training. (Photo: Dr. Barak Amram/VetMoves)

Data compiled and analyzed in a research project in Great Britain funded by The Horse Trust found that racehorses who recovered from tendon injuries did not have inferior racing performance records compared to horses that had not had tendon injuries.

The research was led by Bryan O'Meara, who is in the final year of a three year clinical training scholarship funded by The Horse Trust. O'Meara carried out the research at Donnington Grove Veterinary Surgery in Newbury, under the supervision of epidemiologist Dr Tim Parkin from University of Glasgow.

Tendonitis is one of the most common musculoskeletal injuries in racehorses, with a prevalence of 11-30%, according to earlier research.

O'Meara examined the clinical records and racing histories of 400 racehorses who had been treated for superficial digital flexor (SDF) tendonitis injuries over a five year period from 2003 to 2008.

The race records of horses affected by tendon injury were compared with 400 matched control horses that had never suffered SDF tendon injuries. The controls were horses training in the same establishment at the time of injury and of the same age and sex as the case horse.

The Horse Trust-funded research looked at the performance of the racehorses in races before and after treatment for the injury, and at the performance of the control horses before and after the treatment date. The Racing Post Rating (RPR), which is published by the Racing Post (a British racing newspaper with charts) after every race, was used as a measure of performance.

O'Meara found that there was no significant difference in RPR before and after the treatment date in case and control horses.

This result is unexpected as in vitro studies have found that healed tendon tissue has reduced elasticity properties due to the presence of scar tissue. This suggests that a horse with a healed SDF tendon would need to work its muscles harder to compensate and would therefore be expected to have lower performance.

O'Meara said more research is needed to back-up his finding that performance isn't significantly affected by tendon injury.

"It could be that using Racing Post Rating to measure performance isn't sensitive enough to pick up a change in the horse's performance," said O'Meara. "However, it's encouraging that there's no marked change in performance after a horse has recovered from a tendon injury. These findings show that there's no need to give up on a horse that has a tendon injury--they can still come back and perform well, or can be used for other, less demanding riding activities."

The Horse Trust-funded research also found that there was no significant difference between case and control horses when returning to racing and completing three races. Only after completing five races, or three years post treatment, was a significant difference found between case and control horses. This finding is a step towards developing a more accurate assessment of tendon-treatment outcome after five races or three years post-treatment is a better indicator of the outcome of treatment.

"At the moment, some tendon treatments state their success as the percentage of horses that return to racing after treatment. However, we've shown that there's no significant difference between case and control horses at this time," said O'Meara. "At the moment, there are a myriad of treatments available to treat tendonitis. Hopefully this finding will be used in further research to learn which treatments are most effective."

O'Meara's research also found a link between SDF tendon injury and the racehorse competing at its maximum performance level: the case horses were significantly nearer to their pre-injury maximum performance level in the race immediately before injury (compared to matched controls), suggesting that they were competing nearer their individual maximum performance level when the SDF tendon injury occurred. (Note: this statement is not explained but would seem to suggest that either the level/class of the race or the distance perhaps was the best the horse had done in its career when the injury occurred.)

Editor's note: Information in this article was provided by The Horse Trust, a British charity that funds equine research and promotes education about horse health and welfare. Hoofcare Publishing likes to support The Horse Trust whenever possible. The research described in this article was published in the May 2010 edition of the Equine Veterinary Journal and is available online as a downloadable PDF file: "An investigation of the relationship between race performance and superficial digital flexor tendonitis in the Thoroughbred racehorse".

Readers should keep in mind that the study included only British racehorses and that the majority of British racing is done on grass. Race distances, conditioning schedules and training methods also vary in Great Britain from methods used in North America and some other countries. But the results are interesting, no matter where you live!

Hoofcare@WEG: Paparazzi Moments at the World Equestrian Games


Great Britain's Eventing Team Farrier Brendan Murray carried the British flag into the arena for his country in the opening ceremony. All the British riders followed him.

Here's a great story: Backstage at the opening ceremonies on the first night of WEG, almost 60 nations' riders were lining up. It was an endless line of happy people in national uniforms with video cameras, cell phones, signs, stuffed animals, and noisemakers. They were ready to have fun, although they were clearly honored to be there and be representing their countries.

Ahead of each nation walked three young girls in jockey silks. They carried a sign with the country's name. Next came an individual rider who carried the flag, and then the mass of riders followed the flagbearer.

The rider who carried the flag was elected by the riders. I saw Karen O'Connor carrying the US flag. I saw dressage great Isabell Werth carrying the German flag. The Crown Prince of Dubai carried the flag of the United Arab Emirates. Eventing rider Andrew Nicholson carried the flag of New Zealand.

So I did a double-take when Great Britain gathered at the in-gate to march in. I scrambled for my camera, even though it was totally dark outside. I hoped for a super-flash, just this once. And I got it.

Farrier Brendan Murray was carrying the British flag. It really was Brendan! I found out later that Brendan is retiring as the eventing farrier for the British team; he's been to who-knows-how-many World Equestrian Games and Olympics as the team farrier, and this WEG will be his last. So, apparently, as a show of support and appreciation, the riders elected him to carry the flag.

I still get a little teary-eyed when I look at this picture.

But at the end of the parade of nations, all but one country had passed. As the host nation, the US was last and backstage there was a mass of people getting ready to march into the arena. I took a big gulp when I saw that the girl who lived around the corner from me back in Shirley, Massachusetts had been chosen to carry the flag for the USA. Karen Lende O'Connor was leading the pack of US riders into the arena, and rightfully so. Who ever thought either of us would be here? Wait until I tell the gang back home.

I barely had a chance to wipe my eyes when not three feet from me was another familiar face. Stephen Teichman, US Team Farrier, was marching into the arena with the riders and looked fantastic. He belongs with them; I know how hard he works and I was thrilled to see him.

I could only wonder who might come by next.

But that wasn't the last great moment of that night; there would be many more, including standing next to Muhammed Ali--who ever thought I'd be able to say that? Even at his age and in his health condition, you feel something, as if he could still float like a butterfly and sting like a bee. The man still has it!

I tried to explain some of the USA cultural and horse things to the UAE team (although they insisted that the Saddlebreds were from Poland, no matter what I said); they had never heard of Wynona Judd but the Crown Prince nodded his head when he heard "My Old Kentucky Home" and smiled, "Kentucky Derby song!" They weren't impressed with William Shatner at all until I explained that he was Captain Kirk in Star Trek, then they paid attention.

"Look who's here!" Farrier Hans Albrecht on the Red Carpet at the premiere of Secretariat, by Fran Jurga on the Pavement.

I had a lot of paparazzi competition tonight at the Lexington (Kentucky) premiere of the Disney film Secretariat, starring Diane Lane and John Malkovich. It was such an honor to be invited but I couldn't resist the red carpet. If I stood there, all the celebrities would pass by and I could snap their photos! Here comes the first wave now! They're actors from Hollywood, for sure. Ready, focus...

Hey, wait just a darn minute! That's Hans Albrecht, a farrier from California, or Lexington, depending on how long you've known him. Someone from the Hoofcare + Lameness community was strutting down the red carpet!

I don't know what Hans was doing there or what his connection to the film is nor did I run into him later in the night, as I told him I would. But from now on, he's "Hollywood Hans", in my book. He looked right at home on the red carpet!

I'll never make it as a real paparazzi, since I don't have the nerve to stick my camera in someone's face. I notice that my photos of all the famous riders at the Games seem to be of their backs and all the photos of the famous horses seem to be of their feet--perhaps so only I can match them up.

But every once in a while, the little camera in my pocket comes in handy and I know I'm in the right place at the right time. Brendan and Hans were having the times of their lives when I snapped these two photos. My camera caught that moment for each of them--and for all of you--and saved it forever.

Hoofcare@WEG: Rob Renirie's Dutch Gold Shoeing Keeps It Simple

The Dutch have dominated the dressage at the World Equestrian Games with a sweep of all three gold medals. In this photo you see Exquis Nadine, ridden by Hans Peter Minderhoud, giving an uncharacteristic bolt which showed off her front shoes. All the Dutch horses were shod with straightforward quite uncomplicated shoes applied by a highly skilled farrier. (Dirk Caremans photo courtesy of Alltech)

The star of the World Equestrian Games, so far, has been the spectacular black Dutch Warmblood stallion Moorlands Totilas. He won two individual Gold Medals and led the Dutch to a team Gold Medal. The Dutch have a good sense of humor so he trotted into the arena for the medal ceremony in "solid gold" bell boots. His shoeing is very straightforward. (Detail of a Dirk Caremans photo courtesy of Alltech)

The man behind the Dutch team horses' hooves is farrier Rob Renirie. He has been the team farrier for The Netherlands for many years. He's caring for the hooves of all the Dutch horses at WEG; this photo was taken at the endurance race. (Fran Jurga photo)

It was really quiet in the office last night. I was uploading photos from the camera and a farrier came in. He'd just arrived from out west and we chatted about what he'd missed. He said something that really surprised me; it stopped me in my tracks. He said he wanted to see the feet on the gold-medal-winning Dutch dressage horses, especially Moorlands Totilas, because he figured that they must have some special gaited-horse type shoeing to get them to move like that. (Totilas has a lot of expression and almost impossible joint extension.)

I had to tell him that the shoeing doesn't have anything to do with that horse's animation, unless it is that the shoeing stays out of the horse's way. I hope that people watching the Games on video don't think that the horse is manipulated by shoes or pads or weights. The shoeing is surprisingly simple on these horses, although every aspect of the balancing and trimming of the feet is no doubt very, very carefully managed. The shoe is just the icing on the cake.

The man managing that hoof balance is longtime Dutch team farrier Rob Renirie. Having him in the United States for ten days is quite a treat. On Wednesday, he left the gold medal celebration in the Dutch camp (perhaps figuring there would be more champagne in the days to come--and if so, he was right!) to go to dinner with 16 American farriers, many of whom were from the local Lexington area. He was very friendly and generous with his information and encouragement for everyone. He hadn't met about half the farriers before, and met some of their spouses for the first time.

He also met Doug Watkins from Breeders Supply, the farrier supply store in Lexington, which he said he wanted to visit before he headed home, Mitch Taylor from Kentucky Horseshoeing School, and a delegation from Rood and Riddle Equine Hospital's Podiatry Clinic, plus many others.

An article about Rob's presentation at the Global Dressage Forum in Holland last year, describes his basic shoeing philosophy as this:

"The coronary band usually makes the shape of the foot and thus the shoe. For front shoes, he prefers a slightly rolling toe which covers one third of the hoof wall. He doesn’t use concave steel on dressage horses, preferring to use quite light flat steel (but not aluminum as it’s very slippery) front and back so that the shoe stays on top of the surface and allows the horse to turn easily. He thins the toe until it’s wider by about 3mm and then he lifts it a little bit, with no clips where possible, and small nails. He files as little as possible of the wall, wanting it to stay nice and straight and strong. For hind shoes, again, he hammers the toe of the shoe to create a rounded toe that so it rolls easily; he doesn’t take the toe too far back and leaves only 4.5mm over the shoe at the back. "

One of Rob's popular sayings is that "You can't make a Ferrari out of a Fiat" and that the horse needs to land on its entire foot. He believes in preserving the horse's toe and frog to absorb shock and create energy for the next stride.

He told me that he worries that single points from articles are often taken out of context and championed by horse owners who disagree with their farriers or veterinarians. He receives many emails and phone calls from U.S. warmblood owners asking for advice on horses he can't see and said he would prefer to hear from the farriers if they feel they need help.

Rob presented a masterclass in sport horse farriery at the Fourth International Equine Conference on Laminitis and Diseases of the Foot in West Palm Beach, Florida in 2007.

Hoofcare@WEG: Cutest Farrier Rig at the World Equestrian Games

I don't know how Sandy Johnson gets any work done. Everyone is so curious about her cute little shoeing trailer that she has to keep showing it off. But she doesn't seem to mind.

Shoeing trailers have become the road fashion accessory of the American farrier for the past few years. Some farriers work out of them on a daily basis, and get to enjoy having a truck that functions as a truck. Or they can pull a small trailer with a smaller truck or SUV, as Sandy has done with this Honda Pilot.

The little black trailer was built this spring from Sandy's scale drawings by Stonewell Forge in Genoa, New York.

Sandy lives in Wellington, Florida, where she and her husband, Joe, operate their International Farrier Service. Horses shod by IFS competed in the Dressage at WEG in the first week and will compete in the Para Dressage in the second week. Sandy was credentialed in horse handling operations for WEG and you might have found her out on the runway at the Cincinnati Northern Kentucky International Airport, riding the high-low up and down with a bouquet of leadlines in her hand. Joe and Sandy were the US Team Farriers for show jumping at the World Equestrian Games in 1996 in Rome, Italy.

The black trailer is only used to service clients in the north during the off season. Sandy's is one of many clever designs rolling down the highways that are saving space and gas and making convenient unhooking locations or even transporting shoeing trailers within cargo containers for overseas work or inside big horse vans or moving vans. Try doing that with a truck.

Sorry it was raining when these photos were taken!

Hoof Balance Perspective: Duckett and Caldwell Speakers at Oakencroft’s October Podiatry Conference in New York

Do you know the difference between Duckett's Dot and The Bridge? For years, the Dot stuck in people's memories but the Bridge was probably where most people thought the Dot was. This is a useful illustration technique used in Dr Lisa Lancaster's book, The Sound Hoof, for her explanation of Duckett's system.

Who: Farriers and veterinarians

What: 5th Annual Farrier/Podiatry Symposium

When: October 15-16, 2010

Where: South Bethlehem/Selkirk, New York (near Albany)

Presented by The Clinic at Oakencroft and Greene County Horseshoe Supply

A Hoofcare + Lameness Recommended Event

Sometimes I sit in the dark watching speaker’s slides at conferences and think like an Irish country matchmaker. I’d like to see her talk on the same program with him, or get this German together with this Australian, or whatever, and see what they come up with when a horse walks in to be evaluated.

When I heard British educator Mark Caldwell roll through the results of his research that had compared different hoof balance methods over a shoeing period, I wondered if Dave Duckett knew that someone had put his “Dot” (and Bridge and all the rest of his landmarks) to the test not just of measurement, but of time.

As it turned out, he didn’t know, but the news got his attention. Now it’s time for the two to present their versions of what hoof balance was, is or will be, side by side on the same program. It's a speaker-match made in hoofcare heaven.

Two years later, the man with all the hoof balance testing tools and the man with all the ideas in his head instead of on paper will present their views on hoof shape and balance together, and perhaps re-define or update their studies, or influence each other. Consider this: is the best trimming method for a foot the method that leaves the foot looking balanced when the farrier drives away, or is it the one that prepares the hoof to grow out evenly and maintain a balanced base and flat landing over the four or six or eight week shoeing period?

A foot map to where, exactly? This exercise included mapping out the foot as it existed at the time of trimming. Caldwell sketched in the wider base of frog that is one of his goals for this foot to show his students where the foot would be going, if it was trimmed not for the moment but for the continuum until the next farrier visit. If you're trying to help the horse develop the frog, would you trim differently than someone who thought this foot was acceptable as is? Should you map the foot the horse has or the foot the horse is capable of having?

THE SPEAKERS:
David Duckett FWCF: The well-known and highly honored British farrier and farrier competitor now lives in Pennsylvania. By my math, this year should be roughly the 25th anniversary of his first major hoof balance lectures. Based on observation and a lot of dissections and anatomy studies, Duckett’s idea was to get farriers interested in hoof anatomy by giving clever names to landmarks. His hoof balance system strives to inspire farriers to focus on the points on the horse’s foot least likely to change rather than to dwell on shapes that can and do migrate or grow unevenly. In spite of his system’s simplicity, or perhaps because of it, it is very often misunderstood and the points are transposed.

Mark Caldwell FWCF instructs the farriery courses at Myerscough College in England. He trained as a farrier in the British Army and then became a specialist in shoeing horses for lameness problems at a veterinary hospital before turning to teaching. His research studies use gait analysis and weight-scanning mats; his quest is to define what he calls “evidence-based farriery”.

Mark is currently involved in a post-graduate PhD program studying "limb loading and the effects on hoof capsule morphometrics" at the University of Liverpool Department of Veterinary Clinical Science in Liverpool, England.

Together, these two speakers can explain where the ideas come from (Duckett) and what happens when you put the idea to a test that filters out the subjective tricks we play on ourselves when we evaluate horses’ feet (Caldwell). This clinic is a chance to hear “from the horses’ mouths” where in the world “Duckett’s Dot” came from…and perhaps where it is going in the future.

In other words: this will not be a shoemaking clinic. This clinic most likely will be about looking at feet and identifying/evaluating the matrix that dictates a foot’s shape and growth pattern.

THE CONFERENCE:
The Clinic at Oakencroft’s Podiatry Conference is a casual and friendly event in a beautiful location in rural New York near the Massachusetts and Connecticut borders, just south of Albany. The Clinic hosts monthly meetings with local farriers and they feel at home there—you will, too.

The format of the conference is presentations, discussions, and lots of great food. There are hotels nearby.

Full conference, hotel and registration information can be downloaded at this link:
http://www.oakencroft.org/Articles/5th_Annual_Podiatry.Farrier_announcement%5B1%5D.pdf

The clinic fee is $300 for both days, $200 for Friday only or $150 for Saturday only. Registration should be complete by October 1st. Late registration will be at the discretion of the Clinic, as space allows.

Registration can be done online, by mail, or by phone. If you have specific questions or wish to contact the clinic, you may call 518 767 2906 or send a fax to 518 767 3505.
