Laminitis In Action: Coffin Bone Rotation Time Lapse Video (International Laminitis Conference Preview)

Laminitis, caught in the act: The foot of a horse suffering from Potomac Horse Fever is recorded as it goes through two processes subsequent to the damage in the foot caused by the disease: the coffin bone appears to be rotating away from the hoof wall at the toe and down at its tip; it is also "sinking" within the foot. These two processes are called rotation and sinking, or sinker syndrome. Many laminitis terms have parallel names in other parts of the world or even within the same country. (Andrew Van Eps video)

(You might have to watch this a few times, and if you have a slow connection, you might need to click on the stop button. Once the video is buffered, it should play smoothly. Watching it in full-screen mode helps.)

What you are seeing is a time-lapse of the radiographic view of a horse going through the process commonly called "rotation". What rotation actually is and which part of the foot is the chicken and which is the egg is perpetually debated. This particular foot is also "sinking" within the hoof capsule.

Andrew Van Eps
The video was created by Andrew Van Eps, BVSc, PhD, MACVSc, DACVIM of the University of Queensland. Dr. Van Eps earned a PhD while he was researching laminitis at the Australian Equine Laminitis Research Unit under Dr Chris Pollitt. Among the insights Dr. Van Eps' PhD research has contributed to the treatment of laminitis is the efficacy of cryotherapy in the prevention of laminitis. He created the video of the Potomac Horse Fever case during a residency at the University of Pennsylvania School of Veterinary Medicine.

At the Sixth International Equine Conference on Laminitis and Diseases of the Foot in West Palm Beach, Florida next month, Dr. Van Eps returns once again to speak. Among his subjects will be suggestions for ways to apply cryotherapy, clinical techniques to prevent support-limb laminitis and his intriguing-sounding lecture, "Lamellar Bioenergetics Studied Using Tissue Microdialysis".


You might be interested in reading "Equine laminitis: cryotherapy reduces the severity of the acute lesion" and "Equine laminitis model: cryotherapy reduces the severity of lesions evaluated seven days after induction with oligofructose" by van Eps and Dr. Pollitt, originally published in 2004 and 2009, respectively, in the Equine Veterinary Journal.

He's probably forgotten all about this video. But to anyone dealing with laminitis, the question of whether or not rotation is inevitable in a given horse remains a paramount concern. How many horses technically experience laminitis and have damaged laminae, but have minor rotation or none at all, and why is there such variation between horses? How many horses have bouts of laminitis that their owners never even notice? Is it still laminitis if no one notices but the farrier, the next time the horse is due to be trimmed or shod?

And what is rotation? Is the deep digital flexor tendon, which attaches on the underside of the coffin bone, actually pulling up and back on the bone as the laminae at the toe loosen their hold on the bone, as we've been taught, and as this video would so nicely illustrate? Or is it the weight of the horse on the compromised structures, compounded by unusual posture, that encourages a combination of those forces to work in concert?

A paper from New Zealand published in this month's (September 2011) Equine Veterinary Journal proposes that the soft tissue structures in the back of a contracted, bar-humped foot make it possible for the palmar processes of the coffin bone to act like a fulcrum around which the coffin bone rotates, and that the tendon has no involvement. (See "The effect of hoof angle variations on dorsal lamellar load in the equine hoof" by Ramsey, Hunter and Nash.)

Lead author Gordon Ramsey was kind enough to send his paper and this section begs to be highlighted; using a Finite Element analysis model, Ramsey calculated forces on the proximal hoof wall at the toe when the heels are raised, as recommended in some laminitis therapy regimen. Extrapolating from that finding, he challenged the mainstream concept of coffin bone rotation in laminitis.

Please note that the author is from the University of Auckland in New Zealand and so uses "lamellae" instead of "laminae" in his text; instead of referring to raising the heels of the foot, he refers to mechanically altering the palmar angle of the coffin bone. It's food for thought whether measurements of heels and coffin bone palmar angles are interchangeable.

A typical laminitis foot, with increased heel growth, which would elevate the palmar angle of the coffin bone as per Ramsey's FE model. According to his calculations, as that palmar angle is intentionally increased in some laminitis treatment protocols, the stress on the proximal (closer to the coronet) laminae inside the hoof wall at the toe would be increased.

Ramsey writes:

"The first stage of structural failure in a laminitic hoof involves a stretching of the laminar junction (Pollitt 2007), with rotational displacement occurring subsequently. This seems consistent with a mode of failure that begins at the most loaded proximal part of the lamellae, as predicted by this model, with rotation only occurring after the lamellae have been weakened. 

"It has been proposed that rotational displacement of the distal phalanx, as a sequel to weakening or failure of the laminar junction, is a result of the forces imposed by the deep digital flexor tendon (DDFT) and leverage of the dorsal wall on the ground during breakover (Hood 1999). Experimental results have shown that in laminitic ponies the DDFT force is zero for the first 40% of stance and only approaches a normal value near the end of stance, but that the peak vertical ground reaction force (GRF) is only reduced by 13 percent compared to normal ponies (McGuigan et al 2005). 

"Since the peak lamellar load, predicted by this model to occur at the proximal (not the distal) region of the laminar junction, is more strongly influenced by the GRF than the DDFT force and does not occur during breakover, then this mechanism seems unlikely. 

"An alternative proposed mechanism is that the digital cushion and the region of the attachment of the DDFT are a fulcrum about which the distal phalanx rotates (Coffman et al 1970). As both the DDFT and the digital cushion are soft tissues, it seems unlikely that these could provide sufficient support. 

"However, if the hoof has contracted heels or ingrown bars (Strasser 1997), then these could provide support for the palmar processes to act as the fulcrum for rotation. This could explain why in some hooves the distal phalanx rotates but in other cases, where this fulcrum perhaps does not exist, it only displaces vertically."

Friends at Work: Will Hellyer Shoes a Real Shire for Virtual Farmers


Shoeing a Shire horse isn't easy. Neither is describing the process in a little more than a minute but The Farm's "Head Girl" Emma Warner did it.

Yesterday The Hoof Blog commiserated with a researcher who had to explain insulin resistance and its role in equine laminitis in less than three minutes.  Who knew an academic could avoid all the big words and cut to the chase?

Today I was thinking that it's equally hard to explain what a farrier is doing as s/he shoes a horse. And I found someone who did it in a minute and a half. "Head Girl" (that's British for horse manager) Emma Warner had some very good video editing behind her voiceover to make it possible. And in doing it, she manages to avoid many of the cliches and misused terms that many journalists and broadcasters inevitably--and understandably--garble.

Virtual farmers make the decision at a web-managed farm
Farrier Will Hellyer is hard at work on one of the Shire horses at the National Trust’s "MyFarm" project at the 2500-acre Wimpole Estate in Cambridgeshire, England, where over 250,000 visitors a year get up close and personal with farm animals, including many from rare species, on a "real" working farm. They also have the option of joining the farm and can become virtual decision-makers on how the farm is run. It's a very interesting way to use the Internet, and would be a great model for a show or racehorse stable, too.

I became aware of the farm in July when they set up a web cam in the stall of a Shire mare who was about to foal. I thought it would be exciting for people to follow the birth and encouraged people via Twitter to tune in.

Equus Giganticus subsp. shire
The Shire is one of two native heavy horse breeds in England; the Suffolk is the other. Shires are traditionally shod with toe clips. Photo by Lars Lundqvist.

It turned out to be something quite different than what any of us imagined. The foal never took a breath after it emerged from the womb and the experience of watching the process turned out not to be the idyllic, joyful one people expected, but rather the hard, cold realism of life (and death) on a real farm, after all.

The farm said that 800 people were watching at the time.


Watching how the farm handled the publicity over the foal's death was interesting, as the public expressed a wide variety of opinions and reactions, thanks to the open book of social media. The farm seemed to post any and all comments, and take the critical ones in stride.

Insulin Resistance and Equine Laminitis Research: Australia's Melody De Laat's Academic Elevator Video


Imagine the challenge laid down by the University of Queensland to its graduate researchers: give a three-minute presentation encapsulating your doctoral work. Tell an audience of everyday people from all walks of life why it matters, what it's all about. But keep it short. Can an Australian laminitis researcher describe equine metabolic syndrome in that short amount of time--using only one slide? 3-2-1...talk!

What's your elevator speech?

You have to have one.

If you're an entrepreneur, a job seeker, self-employed or just someone who doesn't want to be left in the dust of this ever-changing world, you have to have to an elevator speech. Once all you needed was a firm handshake, and a spare business card in your wallet for when you met someone. Now you need to be able to tell him or her what you do with your life and why you do it in just a few words.

You need to be able to get the message across that you're special and you're interesting and you're worth knowing/hiring/considering, and you need to say exactly why--all in the time it would take to ride a couple of floors on the elevator of a hotel or office building.

When that elevator door opens, your speech is over.

Yes, you're saying...But then there are academics. And forget engineers. Have you ever asked a researcher or engineer what he or she actually does? I know what you're thinking: Maybe there are some elevators in some coal mines in some Third World countries that would take long enough for a researcher's speech to get to the point--if there is one, that is.

But things are changing. We live in an age of pecha-kucha, the PowerPoint challenge to present your idea in 20 slides that change every 20 seconds, whether you're ready or not. It's the age of the "unconference". And the two-minute video rules, thanks to the way that YouTube has reset our attention spans.

So imagine the challenge laid down by the University of Queensland to its graduate research community: give a three-minute presentation encapsulating your doctoral work. Tell an audience of everyday people from all walks of life why it matters, what it's all about. But keep it short.


And if you get your message across? You could be the winner.

Last year, Melody De Laat answered the UQ Three Minute Thesis competition challenge with a topic related to her thesis: The Investigation of Insulin-Induced Laminitis in Horses. Her research at the Australian Equine Laminitis Research Unit (AELRU) focused on how elevated insulin levels, which occur as a result of insulin resistance, damage the sensitive lamellar (laminar) structures of the horse's foot.

And she had to do it on a huge stage, in an even bigger theater, in front of people who knew nothing about horses' feet, let alone about laminitis or insulin resistance.

“Insulin resistance is an increasingly common problem in horses. The lamellar failure, which is known as laminitis, that results as a consequence of the elevated insulin levels in the body is a painful and debilitating condition,” Melody said confidently.

“By uncovering the mechanisms involved in insulin-induced laminitis it is hoped that we will be able to reduce the morbidity and mortality rates associated with this disease.”
 
The Queensland competition was so well-received that it has been extended to other national and international universities in Australia and beyond. Master of Ceremonies for the event is the award-winning science writer and broadcaster with ABC Science Online, and regular judge on Australian ABC TV's The New Inventors, Bernie Hobbs.

I hope you enjoyed Melody's equivalent of her elevator speech. She advanced to the finals, and there are a lot more people in Australia who know a little bit about laminitis thanks to this competition and Melody's PhD.

And--Oh! Is this your floor?

One of Melody De Laat's research breakthroughs on metabolic laminitis was featured on The Hoof Blog on July 1, 2011. If you'd like to learn more, Melody De Laat will be one of four doctoral and post-doctoral researchers from the Australian Equine Laminitis Research Unit (Simon Collins, Melody De Laat, Brian Hampson and Andrew Van Eps are the team) who will accompany AELRU director Chris Pollitt to speak at the 6th International Equine Conference on Laminitis and Diseases of the Foot in West Palm Beach, Florida October 29-31.

Heart-Bars in Heaven: George Platt DVM Has Died

Heart-bars in heaven: George Platt DVM and farrier Burney Chapman waged war against laminitis from one end of the United States to the other. Credit for their remarkable success rate was always modestly given to the only physical symbol of their treatment, the heart-bar shoe. The shoe inadvertently became a talisman of good or evil, depending on where you stood, and evidence to insurers that severe laminitis wasn't always a death sentence.  (© Hoofcare + Lameness file photo)

Dr. George Platt has died.

The legendary veterinarian who spent most of his career fighting the disease of equine laminitis suffered a stroke in late August and died this afternoon.

If you have ever seen, or touched, or made or used a heart-bar shoe,  George Platt had a part in it. The Texas veterinarian teamed up with horseshoer Burney Chapman in the 1970s and together they experimented with treatments for laminitis. They found the heart-bar shoe in an old textbook and gave it a try; the rest is history.

George Platt in 2009
That history was recorded in 1984, at the 30th Annual Convention of the American Association of Equine Practitioners. Platt and Chapman presented the heart-bar shoe as the centerpiece of their treatment protocol which they documented as successful in rehabilitating a long list of cases referred to Platt by insurance companies.

George Platt's specialty, for many years, was answering the challenge of bringing these high-profile racehorses or show horses back from the near-dead. A broken neck in a skiing accident slowed him down for a while and he made a comeback as a lecturer and clinician because he felt the need to keep the heart-bar shoe front-and-center after Burney Chapman's death, and to clear up many of the misunderstandings about its use. But he ended up back in practice in the mountains of Colorado, where he told me he intended to just be a "ski bum". But he couldn't resist working on horses.

A few years ago, George posed for an over-exposed veterinarian fundraising calendar for an animal shelter in Vail. He was at least twice the age of most of the vets who posed--but he stole the show.
He received the "Veterinarian of the Year" Award this year from the Colorado Veterinary Medical Association, and it was one of many accolades to add to his long list.

Dr. George Platt (right) with farrier Eddie Watson (left) explaining heart-bar shoes at the 1992 American Farrier's Association Convention. Their collaboration sent Platt off to write a paper for Hoofcare + Lameness on using heart bar shoes for heel pain, which was quite a radical proposition in those days.

In looking through a file of letters from him, I'm struck by how many times he said "Just kidding!", both as he wrote humorously and as he spoke.

The last letter I received from him is undated. It says: "This is it: I can't explain how to fit a heart bar but I can show anyone how to." And that's what he did. 

I was lucky to have George Platt as a friend. He was a staunch and generous supporter of Hoofcare Publishing; all his contributions, of course, were about heart-bar shoes.

I have to say that he, as much or more than any one individual, changed the course of the way that farriers and veterinarians work alone and together when he teamed up with Burney Chapman.

People are always quick to give George Platt credit for the heart-bar shoe because he was the very first to lecture on it. He and Burney Chapman did much more than wake a horseshoe up and dust it off: They either launched the beginning of a new age or they opened a Pandora's box. Even 25 years later, it is too soon to tell which, but how many horses have benefited in the meantime?

George Platt wasn't one to sit around and wonder what the historians would have to say about him and his ideas on laminitis. He knew what he'd accomplished in his decades of trying to stop laminitis from taking horses' lives.

He might not be able to explain it, but he could show you how it's done. 

And he did. Thank you, George Platt.

Hoofcare Product Development: For Want of A (Glue-On) Shoe, A Horse Is Scratched


The process of modifying prototypes is complicated when even a small change requires creating a new mold, but that is the reality of designing with plastic. But horseshoe entrepreneurs may spend as much time with lawyers, patent drawings and getting approval from show organizations and track officials as they do around horses. (© Garrett Ford photo) 
The Hoof Blog's ongoing series of occasional "guest bloggers" continues today with a timeline narrative about product development, based on a series of correspondence over the past few weeks from our friend Garrett Ford.

I've watched Garrett Ford build an empire based on the original EasyBoot over the last 25 or so years. His company, EasyCare, now makes 18 different kinds of hoof boots and, perhaps more importantly, sets a standard for continual innovation and product development. I can't keep up with their new products.

Invention is part of being American.
Over the years, EasyCare has probably inspired hundreds of people to try their hands at building a better mousetrap, hoof boot, horseshoe or some piece of tack that will help a trail horse move more comfortably or safely across the landscape.

This summer, Garrett moved his company into new territory: he pursed his desire to race a horse in a product his company could design and manufacture. What started out as a curious R+D project led him to tinker with a lightweight hoof boot until it ceased being called a boot and for all intents and purposes became a glue-on shoe.

The problem: the racing stewards at the track vacillated over whether or not it was legal racing equipment.

There's no question that the decision must be respected, but sharing this story will show everyone what entrepreneurs go through and what some of the upfront costs and time expenditures are in getting a new product to the market.

The tester of Garrett Ford's new shoe was an Arabian racehorse named Clunk. The plan was to pull his aluminum raceplates, glue the new urethane cuff boot/shoes on him, condition him in the hills in the shoes, and then bring him back to the track to train and race in the shoes there. Like many entrepreneurs, Garrett was sure that his new product would be welcomed at the track: it would be simple to use for the farriers, economical for the trainers and beneficial for the horses. (© Garrett Ford photo)

When Garrett told me the saga of his shoe, I smiled because I wasn't surprised. Almost every hoofcare innovator runs into a brick wall of some type sooner or later, when and if the product is to be used on certain types of show horses or at the track.

I've seen some people sail over the brick walls, and I've seen others bang their heads against them time and again. I've also seen wonderful products abandoned, never to see the bright lights of a store shelf, simply because the developers didn't have the resources to jump through the hoops that lay waiting for them on the other side of the brick wall.

Unfortunately, Garrett ran into his brick wall sooner instead of later. Fortunately, he is not building these shoes one at a time in his basement. He's not mortgaging his house to finance an injection mold modification. He has the means and the resolve to keep modifying and keep trying until he really does have his own unique type of all-plastic glue-on boot/shoe.

If you ask me, the brick wall was a blessing. Had Garrett Ford merely whipped up four prototype glue-on shoes, glued them onto a racehorse and proceeded to the owner's enclosure at the track, that might have been the end of it. He might have rested on his easily-earned laurels and retired the racehorse to become an endurance horse, as was his original plan. And he might never have thought about turning his prototype into a truly usable product that could potentially be of value to horses all over the world.

Parts of this post in the Hoofcare and Lameness Hoof Blog were published in a different form in the EasyCare newsletter and/or on the company blog under the title The Horse That Wasn't Allowed To Race. Dual copyright from both companies protects this post.

EasyCare hoof boots have been used in almost every horse sport, but have yet to make an impact in racing. Until recently, hoof boots have been much too heavy and bulky to allow a race horse to be competitive. So when the Easyboot Glue-On was developed, Garrett decided to campaign an Arabian racehorse in a modified version of it. And that's where our story begins.

What Could the Glue-On Do for Racing?
Why bother, you ask? Life on the race track presents challenges to the equine hoof. Many racehorses have challenges with brittle walls, quarter cracks, tender feet, lack of support, and contracted heels from continuous shoeing and training stress. When a racehorse rips off a shoe and loses hoof wall, that wall has a difficult time holding nails and, as a result, may miss conditioning and races. Track horses are subjected to pounding workouts and as a result are prone to injury.

For these reasons, and probably many more, the idea of a better shoe for racehorses is fertile ground for any innovative thinkers who spend much time at the racetrack.

Garrett believed that his prototype, which he called the “Easyboot Race” could potentially be the mortar in some of these gaps of the hoofcare needs of a race horse. Some of the objectives the R+D would set out to accomplish would be to design a shoe that would:
  • 1. allow the hoof to expand and contract as nature intended;
  • 2. provide support and comfort for quarter cracks;
  • 3. allow farriers and trainers another tool for problem feet that will not hold nails;
  • 4. allow farriers and trainers an option that flexes and absorbs concussion to extend the horse's health and longevity;
  • 5. be capable of being trimmed and modified to suit a specific horse, track or surface;
  • 6. be less likely to hurt horses, jockeys or spectators if they do come off;
  • 7. allow trainers to train the horses harder and on less than perfect surface conditions;
  • 8. bring an affordable glue-on solution to the track.

In the past, Garrett has tried unsuccessfully to convince racehorse trainers to use hoof boots for flat track training. To set his program in motion, he purchased a racetrack Arabian named Clunk. His plan had four steps: 1) to pull the aluminum racing plates he was wearing when purchased; 2) to improve the trim on his feet; 3) to condition him in the hills and then 4) to take him back to the track and race him in the new Easyboot Race shoes.

Weight of the Prototype

Weights of the aluminum race plates and the modified Easyboot Race shoe were taken after the Race shoes were modified. The average weight of the aluminum plate was 4.5 ounces. There were variances of + .1 ounces and - .1 ounces. These shoes had been worn in one race, on a soft racing surface, and exhibited little to no wear and tear. They were removed within three hours of finishing the race.

The average weight of the reconfigured EasyCare Race shoe was 5.5 ounces. After adding the appropriate amount of glue for proper adhesion, the final weight was 6.0 ounces. The variance was + or - .15 ounces.


Preliminary contact
During this process Garrett met with the stewards (race officials) at the racetrack. They discussed the new shoe and the prospect of racing Clunk in the new design on August 7th, 2011. Garrett said that the stewards were initially very receptive to the design and thought it could be beneficial for many reasons; they asked to see Clunk do an official workout the week before the August 7th race.

Official Workout with Shoes On
Clunk's race shoes were applied (glued) Tuesday August 2, 2011, in anticipation of a workout in front of stewards on Wednesday August 3rd. Garrett reported that Clunk did a flawless workout in front of the stewards, track vet and several jockeys; Clunk’s jockey was reported to be very impressed and said the horse felt more confident and stable. The track vet had no objections and saw many benefits that could help track horses.

The stewards, however, subsequently changed their opinion, informing Garrett that Clunk would not be able to race on August 7th if wearing the Easyboot Race Shoes. They were unable to give a reason or cite a rule in support of their decision.

Rule Violation
On Friday August 5th, Garrett filed a formal appeal and asked the stewards and director for a reason and rule that would not allow Clunk to race in the new EasyCare hoof wear. The director responded with a written response, stating that our new shoe went against rule number 7.608: "7.608 - Bar plates may be used only with the consent of the Division Veterinarian. The commission may limit the height of toe grabs for any breed at a live race meet. Toe grabs with a height greater than the maximum set by the commission, bends, jar caulks, stickers and any other traction device worn on the front hooves of horses while racing or training on all surfaces, are prohibited. The horse shall be scratched and the trainer may be subject to fine for any violation of this rule."

After the decision, Garrett could have simply removed Clunk's Easyboot Race shoes and raced him in aluminum plates but decided instead to scratch him and stick to what he had set out to accomplish. He quickly finished a new mold that was exactly the same shape of the aluminum plate removed from Clunk's hoof after he was purchased.

Although Clunk was not allowed to race on August 7th, he remained entered in the August 21st feature race. Garrett believed that he could modify the Easyboot Race to be an exact copy of an aluminum plate and the stewards could not say it violated the 7.608 rule.

Apple's marketing celebrates invention.
During the mold process Garrett presented photos and drawings to the track’s race director and the racing stewards. He said, “To our disbelief, (he) and the stewards said the new racing plate still violated the 7.608 rule as it was a ‘Traction Device’ and they would not allow Clunk to race in the new design despite the fact it was an exact copy of an aluminum plate.”

On Wednesday August 17th the racing director informed Garrett via e-mail: "Please be aware that we will be unable to provide you with suggested changes to the product to get it to conform to Commission rules. No matter what changes you suggest, it will not change the fact that the device is a traction device prohibited under the Rule 7.608."

Unless EasyCare knows the portions of the shoe that the track officials believe don’t conform to commission rules, the email is correct: he is unable to make changes.

Polyurethane glue-on racing shoes are already out there and being used by some of the best horses and trainers in the sport. Breeders Cup races and major stakes races all over the world on all types of surfaces have been won by horses wearing next-generation glue-on hoofware. Big Brown ran to victory in the 134th Kentucky Derby wearing glued-on Yasha plastic-aluminum hybrid shoes. Shackleford won the 2011 Preakness Stakes wearing glue-on Polyflex shoes. Overdose set a track record on the turf in Germany wearing glue-on Sigafoos shoes.

Scratch
Clunk had been at the track and training in the Easyboot Race shoes since August 8th. Garrett decided to scratch Clunk from the August 21st feature race rather than change his equipment the day before the race.

State Racing Commission Presentation
Next, Garrett made plans to attend a September 13th racing commission meeting. “We have indicated that we would like to be part of the meeting as we would like to do everything possible to hit the ground running for the 2012 race season at this track,” Garrett wrote.

Men of Progress
The painting Men of Progress by Christian Schussele, completed in 1862, pictured the individuals who had "altered the course of contemporary civilization". Along with Cyrus McCormack, Elias Howe, Samuel Colt and others is Henry Burden, American horseshoe inventor and manufacturer. Also in this painting: Charles Goodyear, the inventor of vulcanized rubber, who died penniless. The Goodyear Rubber Company was named in his honor, as a consolation, years later.

“The goal of the presentation is to go over the allowed hoof protection, compare to the current Easyboot Race shoe and discuss the ability to race at the track in 2012. If our current shoes does not fit into the current rules I would like to find out what portion of the shoe needs to be changed so it does conform.”

Moving Forward
On September 13th, Garrett reported in after the meeting, “I was told by the commission and the director of the track that regardless if the product complied with the rules (or not) that I would need to go through a process or testing with universities. They were unable to give me a protocol...

“I asked what they wanted to see, how many universities, what kind of studies etc. They had a hard time answering. They are asking me to collect different types of study data to prove our device but can’t document what types of study data they are looking for. All of their commission meetings and rule meetings since 2006 have minutes and I can’t find one mention of them asking another company or inventor to prove a new device used on the track in the same way. They don’t have a formal written process that stipulates the kind of testing a new product needs before being approved.”

"In the months to come, I hope to pull some of the horses with foot issues off the slaughter-bound truck at the track and fit them in the new Easyboot Race shoes. I would like nothing more than to show that a horse heading for a processing plant in Mexico was saved, turned around and could win races again in Easyboot Race shoes.

"We will continue to persevere and believe the track officials will accept the shoe.

"At this point in the process, I am turning to the Hoofcare & Lameness community of top professionals and the benefit of this blog's reach into the global mainstream horse industry to ask for consultation. Do Hoof Blog readers believe the racetrack industry could benefit from more choices in alternative hoof wear and more urethane shoe options? Do you have a horse or know of a horse that would be a candidate for the new Easyboot Race shoe?"

Farrier Travis Burns Promoted at Virginia-Maryland Regional College of Veterinary Medicine


Travis Burns
Farrier Travis Burns recently received a promotion to faculty level at Virginia-Maryland Regional College of Veterinary Medicine. Travis is now "lecturer and college farrier" at the Blacksburg, Virginia campus.

From the Hoof Prints newsletter of the veterinary college's Equine Field Service: "Travis Burns, hospital farrier, was recently promoted to faculty status in recognition of his important contributions to the college’s clinical, instructional, and outreach programs, particulary in podiatry. It is great to see our faculty and staff rewarded for their efforts."

Travis joined the university in the winter of 2010 and has been helping Professor R. Scott Pleasant, DVM, MS, Diplomate, ACVS create what is shaping up to be an innovative and energized equine podiatry unit at the vet school.

Travis's background includes a Bachelor of Science degree in animal science from North Carolina State University, a stint at farrier school, and completion of the unique professional internship program at the Forging Ahead multi-farrier sport horse practice in Round Hill, Virginia. While with Forging Ahead, Travis had exposure to podiatry cases when assisting Paul Goodness in his work as consulting farrier at the Marion du Pont Scott Equine Medical Center, which is affiliated with the university. 

Obviously, Travis liked what he saw; he seized the opportunity to specialize in podiatry. He and Dr. Pleasant will hopefully inspire others to be creative about career specializations and the initiative to develop forward-thinking programs where once none existed.
