Keratoma Surgery Video: Case Study from World Horse Welfare

by Fran Jurga | 20 April 2009 | Fran Jurga's Hoof Blog

What's a keratoma? An irritation in the hoof wall, or perhaps trauma or some other cause, can disrupt the keratinization pattern in the wall. The horn tubules grow abnormally and form what could be called a horn-filled, non-cancerous tumor. Since it is caught under the hard wall, it presses against the soft tissue of the laminae that surround the coffin bone, or may press against the coronary band and disrupt growth. And it would probably cause a horse a lot of pain.

Yet many horses have keratomas and never show signs of lameness. When a radiograph suggests a keratoma may be present in a lame horse's foot, the horse will have minor surgery to remove it; in most cases the horse improves. The cause and treatment of keratomas seem to be of mild interest to most vet practices.

But if you can read the vet journals and farrier books from Europe, you might think we're missing something. Just as the Eskimos have 100 words for snow, they have a word for every specific condition in the foot and keratomas are classified into groups so that they start to sound pretty interesting.

You will agree if you ever attend a lecture by Dr Hans Castelijns of Italy on keratoma surgery; it is a “don’t miss” opportunity. He says that the German vets and farriers differentiate strongly between a regular keratoma, which he says originates at the sole, and a strand-like tumor that runs the entire length of the wall and originates at the coronary band.

Dutch author Rob Van Nassau in his outstanding book Hoof Problems, classifies equine foot keratomas into three types: fan-shaped, toe, and side wall.

In the nipper jaws you can see the vertical strands of the keratoma that was removed in the initial surgery.


Today’s case involves what is probably a strand-like tumor in a foundered pony named Toby that was rescued by our friends at World Horse Welfare (formerly the International League for the Protection of Horses) in England. It took two surgeries to remove the entire keratoma.

As an introduction, the pony was severely overweight and laminitic; when the laminitis pain was relieved, he still had pain in his toe, and radiography showed a defect that was attributed to a keratoma, so surgery was performed (top photo). The process involves removing a strip of hoof wall. Most horses recover quickly and fully. Surgery is usually conservative because removal of hoof wall at the toe can de-stablize the foot.

After he had recovered and the hoof wall healed, Toby started to develop a bulge around his coronary band so the decision was made to go a bit higher with the surgery and remove more tissue and get to the root of the keratoma.

This is probably the strand type of keratoma referred to by Dr. Castelijns. A similar but more worm-like non-horny growth was featured in Hoofcare & Lameness 78 in an article by Andrew Poynton FWCF. While working on that article with Andrew, I found an old 1800s paper that suggested that these strands really were worms that were lodged beneath the hoof wall and were eating the soft tissue, causing great pain.



Settle down for a few minutes and watch Toby go through his surgery under the capable care of vet Andy Williamson at World Horse Welfare's Hall Farm in the United Kingdom. This might be a great video for horse owners to learn about surgery and anesthesia, too. The first surgery was done with Toby standing, but this one was more involved.

It looks like a simple affair to make a video like this but for Mr Williamson to perform surgery with a camera crew hovering over him and all the while speaking into a microphone and sounding coherent is quite an accomplishment.

World Horse Welfare takes their role in educating people about the best possible care of horses very seriously, whether they are working in the scrapheaps of Soweto in South Africa or keeping an eye on horse welfare at a posh three-day event. When they take time out to make educational videos that will help with hoofcare education and offer them to Hoofcare and Lameness readers, I am amazed at the scope of their mission and their service to the horse. And their generosity.

Please take some time to visit their web site and look around; their laminitis prevention work is wonderful. They need your support...they certainly have mine.

Meet NEAEP. Now Ask: Who's an Equine Practitioner? New Org's Broader Definition Includes Vets and Farriers; Meeting Discount for Hoofcare Subscribers

by Fran Jurga | 19 April 2009 | Fran Jurga's Hoof Blog

NEAEP President Christopher ("Kit") Miller DVM and NEAEP Board Member David Farley work together in the barn aisle and in the board room. (NEAEP photo)

And now for something completely different...

A new organization unleashed a flurry of email promotions on the east coast of the USA this winter, and they're not done yet. The message is that a new organization, the Northeast Association of Equine Practitioners (NEAEP), plans to expand what (and who) an equine practitioner organization is by inviting veterinarians, technicians and farriers to become members of the new umbrella professional group.

And they would recommend that everyone's first step--whether members or prospective members--be to plan to attend an equally ambitious dual-program conference planned for the fall at the Foxwoods Casino Resort in Connecticut.

According to its web site, the mission of the NEAEP is "to improve the health and welfare of horses by providing state-of-the-art professional education and to support the economic security of the equine industry by complementing local associations thereby giving equine veterinarians, farriers, technicians, veterinary students and horse owners a unified voice at the state and regional levels."

Two farriers--Patrick Reilly of Pennsylvania and David Farley of Florida--are on the new association's Board of Directors.

Reilly said, "It is fantastic to have these two professions working together in these areas. While this was intended as a regional association, we have had interest in membership from farriers all over the United States, and from as far as Ireland. I am encouraged to see that other farriers are equally excited at this unique opportunity for our professions to work and learn together."

I caught up with Dave Farley recently to ask him about the organization from the working farrier's point of view. Dave is a longtime advocate of continuing education for farriers; he runs a show horse shoeing business with his son, both in Florida and in Ohio, and keeps up a busy clinic schedule working in product development and especially product education for Farrier Product Distribution.

"This is a commitment, it's not an experiment," Dave stressed. "And the wider membership extends to vet students and technicians. The NEAEP is committing to hosting a foot conference each year, which will benefit any farrier. It's really exciting, and a very open group. The veterinarians are willing to learn from us (farriers).

"One of the biggest accolades in the farrier industry is this, to be accepted on an equal level," he continued. "And here it is. I work with vets all the time, but I know a lot of farriers who don't, and this organization will help them."

Perusing the list of directors and officers of the organization shows that this group is rooted in the east coast circuit of show horses and sport horses, with several noted veterinary practitioners making a commitment to the startup, including Dr Mark Baus of Fairfield Equine Associates and Dr Stephen Soule of Palm Beach Equine Clinic. President Miller practices outside New York City.

The academic side of equine practice is not forgotten; Dr Jose Garcia-Lopez of Tufts Cummings School of Veterinary Medicine is currently President-Elect, and Reilly, the farrier quoted earlier, is on staff at the University of Pennsylvania and is on the board with Farley. You may recognize other disciplines and individuals on the long list of officials.

Hoofcare and Lameness has made a commitment in this venture as well. We will support the first conference and look forward to seeing many of our Hoof Blog readers and Journal subscribers there.

CONFERENCE DISCOUNT: The NEAEP has generously offered a $75 conference registration discount to Hoofcare and Lameness subscribers. This is like getting your subscription for free...with money left over! The catch is that you must pre-register by August 15th and, since the online registration is automated, you would need to register by phone to receive the discount. The normal registration for the three-day event is $465; the Hoofcare and Lameness rate will be just $390 for telephone registrations by August 15th.

By the time August rolls around, you will have forgotten this announcement, lost it, be away on vacation or be too busy to call. But you can get your registration done now, guarantee a hotel room, and plan to have a quality educational experience.

See you there!

High-Tech Plastic Glue Shoes Carry American Horse to Historic Win at Dressage World Cup

by Fran Jurga | 16 April 2009 | Fran Jurga's Hoof Blog

UPDATE: Steffen Peters' freestyle score on Saturday night was high enough to put him over the top and declare the USA winner of the 2009 Rolex FEI World Cup in Dressage in Las Vegas. This is the first-ever non-European victory in the World Cup. Peters bested Germany's Isabel Werth on Satchmo by only .45 points; Dutch defending World Cup champion Anky Van Grunsven on IPS Painted Black--her #2 horse--was third.

The following story was written on Thursday night when Peters and Ravel won the Grand Prix, the first event in the World Cup competition. That was a shock in itself; this overall victory is astounding.

Two important bits of horse history were made and celebrated in the Thomas and Mack Arena in Las Vegas, Nevada today: First of all, an American horse and rider combination won the Rolex FEI World Cup Final Grand Prix, first leg of the Dressage World Cup Finals.

This is akin to an American soccer team winning in the FIFA World Cup! Steffen Peters and the black Dutch gelding Ravel bested second place rider (and defending World Cup champion) Anky Van Grunsven of The Netherlands by 3.8 points in a sport that is usually decided by decimals--and has never been won by an American!


But the Hoofcare and Lameness community will want to know that this was more than a sporting victory: it was a technological victory, as the San Diego-based duo did it the new-fangled way. Ravel has now won 11 shows in a row in the USA and finished fourth in the 2008 Olympics wearing glued EponaShoes on his front feet. Ravel is shod by Stephan Tournier of Fallbrook, California.

It was a great night for innovators in the hoof technology world.

I spoke with John Craig of Eponashoes tonight, who said that he and his wife, Monique, are thrilled for Steffen and Ravel; they are also the developers of Metron software for quantitative hoof measurement analysis. John said that the shoes are held on by glue and a couple of nails, as well, in the case of this large warmblood. Ravel is owned by Akiko Yamazaki of California.

The World Cup will be decided on Saturday night when the top horses from today's Grand Prix compete in the musical freestyle. Stay tuned: a lot can happen, but Steffen has a solid lead.

"The Horse Boy" Rides Today: The Healing Power of Horses Illuminates Our Need to Know More About Autism

"This is a story everyone needs to hear."
--Animal Behaviorist Temple Grandin PhD
(who is also autistic)

Today is the USA release day for the new book The Horse Boy by Rupert Isaacson, a book that has nothing to do with hooves and everything to do with horses on the most elemental level: the power of horses to let us be ourselves and to bring out the best in us.

If you had a child who needed your help with a massive problem like autism, where would you turn after you had been to all the doctors, all the clinics, and all the psychologists? Would you pace around your own dusty Texas backyard, and then turn to your neighbor's Quarter horse mare, to see if she might be able to help? Horses helped you when you were a child, didn't they? And if she did help him...then what? Would you stop there?

Or would you go to the ends of the earth to try to help your child? If a little bit of horse is good, would a lot of horse be better? Would you set aside all the cultural and belief systems you hold and look for help in a place so strange and foreign that only the smell of the horses was familiar?

If you did those things, it would sound and look like the story and photos in this important new book, the true story of a family on the run toward hope, because they already know it is futile to stand still. "It's important to do something," the experts tell them. But no one expected a young family to take on an adventure like this.

A photo by Justin Hennard who accompanied the family on their Mongolian journey.

You may know someone who works with therapeutic riding programs, a special needs teacher or volunteer, a parent or family member with a child who needs some hope, or someone who believes very strongly in the spiritual power of horses to heal humans on many levels. Please tell those people about this book. However, The Horse Boy is not a how-to book, and it's not a text on autism or horse-assisted therapy: it is one family's story...that happens to be a great adventure.

Here's a short clip from the documentary film made about the family's journey to Mongolia. The film premiered at the Sundance Film Festival in Utah this winter and will be in theaters across the US and Britain this fall.
A year ago the readers of this blog forwarded Molly the Pony's story around the world and back again. If you can possibly forward this post to friends today, it might make the difference to some children or some therapeutic riding programs somewhere. I am sure that the publicity surrounding this book will be wonderful for all who are involved with equine-assisted therapy. Let's get the word out! The copy-and-paste address for this blog post is: http://hoofcare.blogspot.com/2009/04/horse-boy-rides-today-healing-power-of.html The book can be ordered now from Hoofcare Books (see below), or possibly from your local independently-owned bookstore. Editors, journalists: Please contact Fran Jurga about The Horse Boy's horse-related publicity. Click here to read an article about the book in today's edition of the New York Times.

Mo-Cap Video Treat: Horse and Rider in Motion, Video-Captured and Computer-Recreated

by Fran Jurga | 13 April 2009 | Fran Jurga's Hoof Blog



This little clip is titled A Biomechanical Analysis of Relationship Between the Head and Neck Position, Vertebral Column and Limbs in the Horse at Walk and Trot and is from the Department of Veterinary Medicine and Animal Science, at the Swedish University of Agricultural Science in Uppsala, Sweden. Thanks to researcher Marie Rhodin for sharing this little snapshot of what goes on at Uppsala.

Dr. Rhodin writes: "Reflective markers were glued onto the skin above anatomical structures defined through palpation. A high speed 3D infrared camera system (ProReflex) was used to capture data. Twelve cameras were used and a treadmill instrumented with a force measuring system was used for simultaneous, synchronized force measurements. Qualisys software was used for the motion analysis."

Dr. Rhodin's name is one that is seen quite often lately on the rosters of world-class equine biomechanics research. She was involved with two presentations at last year's International Conference on Equine Locomotion (ICEL6) in France. Working with our friend at Uppsala, Dr. Christopher Johnston, and Lars Roepstorff and Anna Byström, and collaborating with researcher Dr. Michael Weishaupt at the University of Zurich and Dr. René van Weeren at the University of Utrecht in Holland, Dr. Rhodin's team collected data on the motion of horses when the rider is in the sitting vs rising (posting) trot, and also compared the motion of the horse on each lead.

What you are seeing in this little video clip is the new generation of motion capture gait analysis--the rider gets analyzed along with the horse! The clip begins with the "real" video of the markered horse and rider; you then see the dots that the infrared cameras would "see" and translate into data. The data is then crunched and re-configured into an accurate animation of the horse and rider in skeletal form so that the movement of the bones and joints can be analyzed. This is a huge advance, since the horse is an asymmetric form and needs to be seen from all angles to get a true picture of movement. (And this is a vast over-simplification of the process.)

Through this type of motion capture, researchers can compare the effects of different equipment (Uppsala recently studied the effect of weighted boots on the movement of the back), different riders, and (one day), different surfaces. Being able to accurately record both the rider and the horse are rocketing equestrian sport science ahead. These are exciting times.

Many thanks to Dr. Rhodin and her research team at Uppsala and beyond for making the video clip available to Hoof Blog readers.

Will You See a Horse Being Shod in Your Church Window on Easter Sunday?


A church window expertly photographed by Dave Webster

Not out the window, but in the window! In at least two churches I've found, farriers are featured in the windows!

The first, which you see above, is in St Cuthbert in Kildale, in North Yorkshire, England. Notice that the farrier is using what we call now a "toeing knife" to trim the hoof, instead of nippers with jaws.

The church hosts some magnificent contemporary (1990s) stained windows by the English artist firm, Goddard and Gibbs. The church windows show a yoke of oxen, too!

Surely there is no more famous farrier window than in the magnificent cathedral at Chartres in France. This window was a gift from the guild of farriers and was sent to Hoof Blog readers by our dear friend, French farrier Denis Leveillard, former president of the European Federation of Farriers.

It's interesting to note that this farrier has a hammer in his hand but he's not nailing on a shoe. He might be guiding some sort of toe knife but the foot is on the ground, so I might need some Euro-coaching to explain this for you. Or maybe he's clinching a nail?

Food for thought: The Cathedral at Chartres was completed in 1260, roughly 700 years before St Cuthbert.

Thanks to Dave and Denis for sharing these images...and happy jelly beans, chocolate eggs and marshmallow Peeps to all!
