Churchill, Arlington, Calder and The Fair Grounds All Ban Toe Grabs

Trainer Steve Asmussen paid close attention to how Steve Norman was trimming his filly Pocahontas during Derby Week at Churchill Downs in 2004. (Thanks to Dan Burke of FPD for this photo.)

This press release was issued today and is printed below verbatim, so that I don't possibly misquote the fine print of what is and is not allowed. I know that this verbiage is still a little confusing, but eventually the what-is-legal-and-what-is-not parameters will sort themselves. The bold terms are mine, to help keep the main points straight.

Brief explanation of terms: Toe grabs refer to traction cleats in the toe bend of the shoe (front of foot). Currently shoes are sold with toe grabs of different heights. Turndowns refer to mechanically bending the heels of the shoe in the back part of the foot. Shoes are sold with flat heels. Turndowns usually refers to a steeper alternation of the heel and a "bend" is a minor turndown.

LOUISVILLE, Ky. (Oct. 14, 2008) - Churchill Downs Incorporated has implemented a new horseshoe policy at its four racetracks that bans the use of toe grabs greater than two millimeters. The new policy is effective immediately.

The policy, which will apply to all horses racing and training at Churchill Downs, Arlington Park, Calder Race Course and Fair Grounds Race Course, states:

"Front horse shoes which have toe grabs greater than two millimeters shall be prohibited from racing or training on all racing surfaces at all Churchill Downs Incorporated racetracks. This includes but is not limited to the following: toe grabs, bends, jar calks, stickers and any other traction device worn on the front shoes of Thoroughbred horses.

"Any hind shoe with a turndown of more than one-quarter inch will not be allowed on the dirt courses.

"Hind shoes with calks, stickers, blocks, raised toes or turndowns will not be allowed on the turf courses. This includes quarter horse shoes or any shoe with a toe grab of more than one-quarter inch."

"Our change in policy is another positive step toward improving the welfare and safety of our equine and human athletes, and it's consistent with the recommendations of The Jockey Club Thoroughbred Safety Committee, TOBA's Thoroughbred Action Committee and the Kentucky Horse Racing Commission to address safety in horse racing," said Donnie Richardson, senior vice president of racing for Churchill Downs Incorporated.

Heel Bulb Injuries 101: Big Brown's Latest Hoof Malady

Earlier today this blog provided details about the heel bulb injury that predicated the disappointing retirement of champion three-year-old Thoroughbred Big Brown. This post will give some background into the type of injury for those unfamiliar with foot anatomy and injury.

(Double click on photo for a much larger detail view.)

A horse's heel bulbs are similar to the fleshy part of the palm of your hand above the wrist, at the base of your thumb. The bulbs are in the back part of the foot, above the hairline and below the "waist" of the pastern. In this photo, which shows a foot cut in half, it is the brownish zone at the right that bulges out from the hoof. The heel bulbs are comprised of soft tissue, namely the digital cushion, a fat-cartilage mass that fills out the foot and provides multiple cushioning, circulation-enhancing and/or structural functions in maintaining the integrity and strength of the foot. The bulbs are covered with skin and hair and are not protected by hard hoof wall or sole. They are a vulnerable structure. (Photo courtesy of HorseScience.com)

This stakes horse at Keeneland suffered a heel injury that might have been similar to Big Brown's. Technically the heel bulbs are the area covered with hair, just below the horseshoer's thumb. The area was filled in and covered with acrylic and a glue on Polyflex shoe was applied by Curtis Burns. This photo was taken when the horse was well into the healing process. Sometimes the hind shoe scrapes down the back of the pastern over the heel bulbs and ripping off part of the heel or pulling off the front shoe. Thoroughbred racehorses frequently suffer from a grabbed quarter, heel bulb lacerations and coronet bruising and cuts because of toe grabs on their shoes. But, as Big Brown showed today, these injuries can occur even without toe grabs. Frequently a hind foot comes up and strikes the front foot when there is a gait abnormality, such as when horses are galloping on soft turf and the front foot stays on the ground a fraction of a second too long and the hind foot comes forward and strikes it. The injury frequently happens when horses scramble out of the starting gate, and can happen to hind feet when "clipping heels" with another horses. Some horses have conformational or coordination problems that designate them "hitters" and suffer from chronic lower leg and hoof injuries. They usually wear bandages, bell boots and have their hind shoes "set back" to reduce the chance of injury when training. Big Brown wore bell boots when schooling for the Belmont to protect his quarter crack patch.

How bad can a heel bulb injury be? This is a case at the Rood and Riddle Equine Hospital's Podiatry Clinic, as featured in issue #79 of Hoofcare and Lameness Journal. Dr. Scott Morrison reconstructed the frog and over time, was able to restore the foot and the young Thoroughbred began its racing career wearing normal raceplates. Heel bulb injuries are common around farms, particularly wire cuts, horses catching a hoof in a cattle guard, pasture injuries, trailer loading mishaps, etc.

Aftermath of a heel bulb laceration: This ex-racehorse shows evidence of a severe injury earlier in its life. The horse is completely sound.

Iavarone: Big Brown Was Barefoot; Injury Not Related to Toe Grabs

I was fortunate to be on a conference call this afternoon with Michael Iavarone of IEAH, managing partner owners of Triple Crown star Big Brown. As reported earlier today, the colt grabbed a quarter at some point in his work on the turf this morning and his immediate retirement from racing was announced.

Among the information that Iavarone shared was that Big Brown was not wearing his glued-on Yasha shoes this morning. He was barefoot. He stressed that toe grabs were not on the hind shoes and that the horse wore no bandages today. The injury happened on the Aqueduct (New York) turf course, perhaps on a turn, although no one has seen video of the incident.

Iavarone said that the colt cut about a three inch wound in his heel bulb. When the owner arrived at the barn, the horse was still walking, which the owner attributed to adrenaline, but the horse grew increasingly resistant to being led around the shedrow.

Trainer Rick Dutrow's immediate worry is to prevent infection. Iavorone did not have specific details on the treatment regimen. He said that the injury was not life-threatening but that it's timing, just 12 days before the biggest race of the colt's life, predicated the decision to announce his retirement rather than start a stop-gap treatment for a miracle cure.

Iavarone had few technical details to share, other than that a gash about three inches long showed where the heel bulb had been injured and that part of the hoof wall was gone as well. He mentioned that the horse was not favoring the limb and was standing on all four feet.

Big Brown will remain in New York for perhaps three weeks to a month and then will go to Three Chimneys Farm in Kentucky to stand at stud.

In my next post, I will share the anatomy of the heel bulbs and some photos of injuries. Iavarone said he would try to make photos of the injury available.

Big Brown has the most well-documented hoof problems in history. He suffered from hoof wall separations in the heels of both front feet this winter and then survived a quarter crack before the Belmont Stakes. Check the April and May 2008 archives of this blog (see column to the right) for much more on Big Brown, including videos of his hoof repair.

Bye Bye, Big Brown: Champion Colt Retired After Foot Injury During Training in New York

Today was the day he booked his van ride to Kentucky.

Champion three-year-old colt Big Brown limped home from a work at New York's Aqueduct racetrack this morning.

Owning partner Richard Iavarone of IEAH is quoted on bloodhorse.com: "Big Brown has been retired. He not only tore the bulb off his foot, but half the foot was torn off. We did everything we could to get to the Breeders' Cup. It's devastating. And what makes it even worse is that he worked great."

Considering that a great portion of both heels of both the colt's front feet were artificial hoof wall and glue holding on a high-tech gasketized Yasha shoe, this is quite a feat.

Iavarone is quoted on the Daily Racing Form web site as saying that the decision was made after consulting with Aqueduct horseshoer Alex Leaf, who was at the track this morning. Leaf had ben a key player in keeping Dutrow's star Saint Liam sound in spite of hoof crises as he won the 2005 Breeders Cup Classic.

Hoof repair specialist Ian McKinlay, who worked on the horse's well-documented quarter cracks and wall separations and designed the custom-made heel insert shoes, was not at the track.

One of the greatest rivalries in horse racing in many years was developing as Big Brown trained toward the Breeders Cup Classic at Santa Anita in California on October 25, where he would have met champion older horse Curlin and the undefeated Japanese mystery horse, Casino Drive.

Next stop for Big Brown: Three Chimneys Farm outside Lexington, Kentucky, where he can share two-out-of-three's-not-bad stories with another almost-Triple Crown winner, Smarty Jones.

Dressage: The Debate Over Biomechanics Goes Live in the USA This Week

 

In the last year, a new word has crept into the dictionary of dressage around the world. "Rollkur" refers to the hyperflexion of the horse's neck as a training procedure and it has rattled dressage cages around the world. 

The man with a stick who rat-a-tats the bars of those cages is German dressage-specialist veterinarian Gerd Heuschmann. And to him, rollkur is just the tip of a huge iceberg. His book Tug of War: Modern vs. Classical Dressage has been a lightning rod for dressage purists, and has enjoyed a perch atop the bestselling horse books list for most of the past year. 

This month, Heuschmann is speaking in the United States and his lectures are sure to re-open the debate. I will hope to catch his biomechanics lecture next weekend at the International Dressage Symposium at Maplewood Warmbloods in Middletown, New York. 

Another clinic with Dr.Heuschmann is planned for February 12-14, 2009 by the Utah Dressage Society. 

If you have a chance to hear him speak, in any language, make the effort but be sure to keep an open mind. It is his mantra that modern "sport" dressage as practiced by some trainers and riders is cruel and he provides compelling, dramatic, and emotional evidence that sport-type dressage is causing damage to horses' musculoskeletal systems. He, and many other proponents of the classical ways of training, believe that dressage training is a long process that can't be rushed. He is not condemning dressage itself, only the practices of certain trainers and the rewards of the current judging system. 

Sample image from the upcoming Gerd Heuschmann DVD; this is a 3D model of the horse used to explain the effects of tension and improper movement in dressage.

Heuschmann's upcoming 60-minute DVD, "Stimmen der Pferd" ("If Horses Could Speak") on the biomechanical exploitation of horses in sport dressage is said by its producer to be the most expensive production ever attempted on the subject of horses. 

As riveting as Dr Heuschmann's arguments may be, and as lavish as his filmmaker's portrayal of the horse, the debate over rollkur lost some of its teeth following the technical and scientific forum by the FEI on the subject, which included Hoofcare and Lameness consulting editors Drs. Jean-Marie Denoix of France and Hilary Clayton of the USA, among others. 

The researchers and the FEI stopped short of condemning the practice, partly because of a lack of biomechanical evidence. Instead, that forum issued stern warnings about possible misuse of the practice and stressed that it should only be used as a training method by experienced riders and trainers. 

The sport of dressage suffered another blow last week when a German television news broadcast showed a hidden camera's' video of a well-known rider/trainer repeatedly whipping a horse while lunging on a small circle. With this post, Hoofcare and Lameness and The Hoof Blog begin sharing with you some exciting original video about equine sport, and especially sport science and biomechanics, produced by Epona TV. 

Epona TV is a subscription-based video library that includes content from Dr. Hilary Clayton and Dr. Gerd Heuschmann, among others.  

Dr. Heuschmann's book, Tug of War: Modern vs Classical Dressage is available from Hoofcare and Lameness.

Vet School Farriers: Change on the Hoof

An article caught my eye today on the web site of the University of California at Davis College of Veterinary Medicine. One of the largest and most horse-specialist vet schools in the country has two farriers on staff now, Marc Gleeson (in the UC Davis photo above) and Bill Merfy. And former farrier Kirk Adkins is still around, teaching a hoof science course for undergrads. The article started me thinking about how hooves are being served at vet schools.
