Prix d'Amerique 2015: 15 of 18 Horses Will Race "Barefoot" by Pulling Shoes Before Race

72 hooves. 6 shoes. (Maybe.)

That's the ratio for Sunday's Prix d'Amerique trotting race in Vincennes, France. The purse is worth $1.15 Million (US). It's the world's richest harness race. You'd take your shoes off, too, for that kind of prize money.

This is not just another horse race. It is a 1 11/16 mid-winter downhill then uphill push to the limits for the world's hardiest Standardbreds. These are the strongest, fastest two-beat trots you'll see anywhere in the world.

But minutes before the race starts tomorrow, the shoe pullers will come out and dozens of shoes will be left behind.

Special thanks to researcher Claire Moiroud and Professor Jean-Marie Denoix, who kindly arranged to share this research project with Hoofcare Publishing. This text is an approved, verbatim translation of a French document and is published to coincide with the excitement of the Prix d’Amerique, one of the world’s great trotting races, at Vincennes, France on Sunday, January 25. That race has been won by horses using the methods described in this article.

Introduction
In French harness racing, it is customary for the trainer to remove the shoes of some horses before races. "Relieve the foot, increase the speed"...that is the goal. Perhaps the immediate benefits seem obvious, but no study has addressed the risks to the horse itself in terms of possible discomfort and especially the risk of excess wear to the feet. That has now been accomplished through the work of the CIRALE-ENVA Hippolia team in Normandy, France.

Navicular Syndrome: Does FDA Approval of Tildren and Osphos Change Anything?

From bone to zone: Focus on navicular-type lameness has evolved from concentrating on identifying bone defects visible in radiography to a more dynamic approach to also detect possible soft tissue injury, deteriorating hoof condition and age- or sport-related stress factors. The navicular bone is circled in this distal limb bone model at the University of Nottingham Vet School.

The landscape of treatment options for equine navicular syndrome is set to change this year, as the U.S. Food and Drug Agency (FDA) recently approved two drugs for use in the treatment of this complex lameness problem in the horse's foot. "Tildren" and "Osphos" are two specific medications that cleared the difficult hurdles of the FDA approval process in May 2014.

Book Announcement: Jean-Marie Denoix's Biomechanics and Physical Training of the Horse Published December 2013

Stop the world, Jean-Marie Denoix's new book is out. The first advance copies of Biomechanics and Physical Training of the Horse by Professor Jean-Marie Denoix are hitting US shores. The official publication date was December 30, 2013.

Biomechanics and Physical Training of the Horse is an expansion of Professor Denoix's landmark earlier and highly recommended earlier textbook, Physical Therapy and Massage for the Horse. The production has been upgraded to a full color format and the author's trademark illustrations are supplemented by copious photographs of leading French equestrians caught in sometimes less than graceful segments of strides, lateral movements, and jumps.

Online Veterinary Anatomy Museum Injects High-Tech Media & Movement into the Study of Equine Structure

What's your vision of an anatomy museum? Giant paintings on the walls? A sculpture of a hoof? Think again! The foot in this photo is from a 3-D movable program that is one of the showpieces of the new Online Veterinary Anatomy Museum. (Larger image © Hoofcare Publishing)

An anatomy museum is a wonderful place. But who among us can travel to Harvard's Museum of Comparative Zoology or to London's Natural History Museum when we feel like studying anatomy?

If we can't go to the museum, can the museum come to us?

Guess what? It already has.

Tiludronate (Tildren) Effective for Hind Limb Lameness Caused by Bone Spavin

Spavin is one of the most common causes of lameness in jumping horses.

Newly published trials from a study in England show that horses suffering lameness caused by bone spavin can show marked improvement following treatment with a Tiludronate (Tildren) infusion, when administered in combination with controlled exercise.

Tildren: Denoix Study Shows Drug Helps Horses with Back Pain

Hoofcare and Lameness Journal first reported on the clinical trials of the drug tiludronate ("Tildren") about five years ago, when it was first tested on horses with navicular disease under the supervision of one of consulting editors, Jean Marie Denoix, DVM, PhD, Agrege, of France.

Dr. Denoix's team recently tested Tildren on 29 horses with back pain caused by lesions in the vertebrae, as documented in radiographs. Such lesions are common in many horses.

Fifteen horses were given Tildren and 14 horses received a control substance, and the horses were monitored for 120 days. This was a similar protocol to the navicular disease study. The horses given Tildren were significantly improved after 60 days.

The study was published in the March 2007 edition of the American Journal of Veterinary Research.

Tildren is currently not sold in the United States but is being used by some veterinarians in trial situations within FDA guidelines. Fortunately, the drug is being tested near here at the New England Equine Medical Center, by Dr. Michael Davis, and I've been able to follow its progress. So far, all the news is good...except for the price, of course!

Tildren has been used successfully for navicular bone lesions and hock spavin. Hopes have been high for its use in demineralization of the coffin bone but I don't think there is any documentation of tests for that problem.

Denoix's new study opens up the area of the back and makes one wonder about using it for neck and sacroiliac pain...but I'm sure he's working on that!

4th International Equine Laminitis Conference in Palm Beach, Florida Planned for November 2007

Mark your calendars for the first weekend in November of 2007, and plan to attend the 4th International Equine Conference on Laminitis and Diseases of the Foot, a.k.a. "Palm Beach Laminitis".

The 2005 event was probably the single largest gathering of Hoofcare & Lameness subscribers ever. I loved every minute of it and look forward to seeing you all again next year!

I'll set up a separate blog for the event and post photos from last year. Watch this space for more information!

In the meantime, here are a few favorites:


Drs. Sue Dyson of England and Jean-Marie Denoix of France, who both spoke at the conference, danced beneath the stars on the top deck of the yacht chartered for all the attendess, speakers, and exhibitors, thanks to our gracious hosts, Mr. and Mrs. John Castle.

Denoix, Dyson and those tricky ligaments

Collateral ligament injury (black arrow) on a case diagnosis by Dr. Sue Dyson at the Animal Health Trust in Newmarket, England

One of the many popular topics covered by Hoofcare & Lameness is the importance of the collateral ligaments of the coffin (distal interphalangeal, DIP) joint. Sue Dyson, lameness veterinarian of the Animal Health Trust in England, has written a super article on injuries to the ligaments and how to identify them.

We pair this with a compelling discussion of the movement of the coffin (distal phalanx, P3) bone by Jean-Marie Denoix. He termed the word "collateralmotion" to describe how the coffin bone moves slightly to the inside or outside, in a gliding motion, which most people do not usually consider when they consider the foot and what might cause lameness.

The collateral ligaments stabilize the coffin joint and allow the limited amount of gliding that a sound horse requires. Excess gliding may injure the ligaments, causing lameness. Conversely, excess gliding (such as "lunge til dead" training techniques) can injure the ligaments.

It certainly is hard to illustrate, however!

Denoix has a superb article in the January 2005 edition of Equine Veterinary Journal about how the weightbearing foot's coffin bone moves under the short pastern bone when a horse is turning. The article was dedicated to the memory of Jean-Louis Brochet, Denoix's sidekick and farrier who died tragically in Paris a few years ago of an unknown disease he contracted while working in Florida.
We are very grateful to have Drs Denoix and Dyson on our editorial board. Both of them will be speaking at the 3rd International Laminitis and Equine Diseases of the Foot Conference in Palm Beach, Florida November 4-6.

AAEP Convention Schedule Announced: Highlights Related to Lameness

The schedule for the 2004 American Association of Equine Practitioners Convention arrived at the office yesterday. The convention will be held December 4-8 in Denver, Colorado, and of course, Hoofcare & Lameness will be there with a double booth this time in the huge trade show.

Here are a few highlights from the schedule that may interest Hoofcare & Lameness readers.

Friday 12/3 Foot Surgery wet lab with Kent Carter, Bill Moyer, and Robin Dabareiner--the Texas A&M hoof surgery team--or Advanced Ultrasound with Jean-Marie Denoix, Norm Rantanen, Ron Genovese, and others.

Saturday 12/4 1-3 pm "Veterinarian-Farrier Relations Committee" is listed; I don't know if this is an open meeting or not. Stacey and I will be there setting up the booth that day (helpers welcome!).

Sunday 12/5 10 a.m. Larry Bramlage presents the "Kester News Hour". This is always fun--a rapid-fire review of veterinary developments over the past year, with some humor thrown in.

Sunday 12/5 NOON--Bill Moyer and our farrier friend Bob Pethick will host a lunchtime "table topic" on therapeutic shoeing. Should be great! Also at the same time: Cushings Disease and Hind Limb Lameness.

Monday 12/6--get up before dawn (or just stay up) for sunrise sessions on foot lameness, gaited horse lameness, racehorse lameness, laminitis, western performance horse lameness, and a lot more by presenters such as Bill Moyer, Tracy Turner, Scott Bennett, Scott Morrison, Steve O'Grady, Jay Merriam, Rick Mitchell, Reynolds Cowles, Kent Carter, Terry Swanson, Jerry Black and many more. You must reserve in advance!

Monday 12/6 1:30 I am looking forward to a group of presentations under the heading "The Unwanted Horse"..but unfortunately at the same time are "how-to" sessions with Tracy Turner, Steve O'Grady and Kevin Keegan on saddle fitting, canker, and head/pelvis movement evaluation in lameness diagnosis, respectively. I won't miss those three, but hope to see some of the welfare presentations, too!

Tuesday 12/7 The sports medicine session starts at 8 a.m. with one of our consulting editors, Sue Dyson, presenting "Collateral Desmitis of the Distal Interphalangeal Joint in 62 Horses". This is a great topic on what I think will be a new BUZZ in our industry. (Read Jean-Marie Denoix's article "Collateral Ligaments of the Distal Interphalangeal Joint: Anatomy, Roles, and Lesions" in Hoofcare #70 for more on this subject.)

Tuesday 12/7 At the same time Sue is presenting, there will also be an imaging panel in progress, with Jean-Marie Denoix, Rick Mitchell, Kent Carter, etc.

Tuesday 12/7 Lameness Program begins at 1:30 (unfortunately overlapping with the tearing down of the trade show! Helpers welcome!) with EIGHT interesting lectures including Sue Dyson again, this time of a VERY HOT TOPIC: "Is there an association between distal phalanx angles and deep digital flexor tendon lesions"? My guess is that she will be comparing lateral radiographs showing P-3 angle with MRIs of the same foot showing tendon lesions in the navicular area. This should be worthwhile. Robin Dabareiner (navicular bursa medication results), Scott McClure (shock waver therapy for navicular disease) and lots more in that special section of the convention.

Tuesday 12/7 Yes, at the same time, there are medical presentations on Cushings syndrome and thyriod dysfunction, plus Jim Belknap on using COX-2 inhibitors in developmental stages of laminitis.

Wednesday 12/8 A terrific program on sacroiliac lameness with Sue Dyson as moderator; speakers include Cornell's Kevin Haussler, Dan Marks, Jean-Marie Denoix.

Wednesday 12/8 NOON Table topics on shock wave therapy and a great one on treating sore backs with Dan Marks and Midge Leitch.

Wednesday 12/8 1:30 pm Hooray! The Hoof! Rood & Riddle's Scott Morrison (see article in our current issue on maggot debridement therapy) and our old friend (and the only farrier on the program) Bob Pethick from New Jersey will do an afternoon program on farriery, with live horses. In the surgery program that afternoon, Robin Dabareiner will speak on heel bulb lacerations and the UK's Andy Bathe will speak about medial patellar desmotomy cases.

-----

Those are just some of the highlights. Also, I don't know what the AAEP's policy is about non-veterinarians attending, so if you are not a veterinarian, you may want to register in advance to avoid late fees on top of non-member rates.

-----
Hotels:The Marriott City Center is the HQ hotel, but the Holiday Inn is much closer to the convention center and $50 less per night. Hoofcare rooms will be at the Holiday Inn.
-------
At the trade show: Visit the Hoofcare & Lameness booth and learn about the exciting new "in the field" (literally, sometimes) gait analysis system from the UK "Equinalysis", plus new lameness-related or farriery products from St Croix Forge, Harmany Equine, Eponaire, Grand Meadows, and The Smart Boot.

PLUS socialize at our booth during book signing events with Joyce Harman (The Horse's Pain-Free Back and Saddle Fitting Book), Hilary Clayton (The Dynamic Horse) and Doug Butler (Principles of Horseshoeing III), to name a few.
