Canker: Seldom Seen But Important to Recognize

Canker in Hoof, originally uploaded by krissid2001.

I can almost smell this photo right through the computer screen. And it doesn't smell good.

Have you ever seen a horse with hoof canker? I've only seen it a few times, but it certainly made an impact. I know that this is becoming more of a problem in horses in the USA, and people are reporting more cases all the time.

The problem is that many owners don't recognize what it is and rarely contact a veterinarian until it is so advanced that you can see it (and smell it) from across the paddock.

Another problem is that it often strikes draft horses, like this Clydesdale or Shire, so the feathers cover it.

If you see something ugly growing on the bottom of a horse's foot, either in the cleft of the frog or the sulci or in the heel bulbs, don't just assume it is a bad case of thrush that will go away when the pasture dries up or when summer comes. Canker often requires the services of a consulting vet or farrier and horses are sometimes put down because of it. Medications and soaking and diligent cleaning are all on the list of treatments.

Thanks to Krissid2001 for allowing me to blog this photo for you all.

So Long, Wonder Pony: Theodore O'Connor 1995-2008

America's favorite pony was put to sleep today after an accident on the Team O'Connor eventing training center in The Plains, Virginia. Karen O'Connor's diminutive 14.1-hand Pan Am gold-medal winning sport pony (ArabxShetlandxThoroughbred) captivated eventing fans with his gravity-defying leaps and amazing athletic precision.

Teddy had been shortlisted for the upcoming Olympics this summer in Hong Kong.

Thanks to Squib Girl for this great photo of him in action. He was an action hero of the horse world, that's for sure.

New York Veterinarian Dead Following Head Injuries from Horse Mishap

,Veterinarian John Steiner has died in the hospital in Albany, New York. As reported here last week, he was injured while performing services at the Rhinebeck Equine practice in Rhinebeck, New York. Dr. Steiner suffered massive head injuries. Scroll down to read more about this tragedy in last week's posts.

Rhinebeck Equine has posted a biography of John Steiner. He had recently moved back to New York to his family's farm after many years living and working in Lexington, Kentucky as a reproduction-specialist veterinarian.

Triple Crown "Crack"down: Update from Ian McKinlay on Big Brown's Latest Hoof Malady

This device from Holland was marketed in Europe for stabilizing quarter cracks on Standardbreds. This photo shows clearly what a typical quarter crack would look like after being cleaned up. Notice where the start of the crack is at the hairline vs where the bottom of the crack is at the shoe. A quarter crack is a fissure in the hoof wall and is a reaction to stress so it will generally follow the angle of the horn tubules if the intertubular horn is weak, or the path of least resistance. Big Brown's crack is only 3/4" long, according to Ian, and is up at the top of the wall.

As promised yesterday, Hoofcare and Lameness caught up with hoof repair specialist Ian McKinlay today. Ian has promised a photo of Big Brown's new quarter crack on Wednesday of this week.

Ian was called to Belmont Park the other day when trainer Rick Dutrow noticed something wrong with the medial (inside) hoof wall on Big Brown's left front foot.

As avid Big Browners will recall, the left front foot is the site of the original wall separation that started the chain of hoof repair and layups for the champion colt over the winter months. Ian had removed the heel tissue on the inside heel of the left front, as detailed in previous posts and videos on this blog. The horse then shipped to Florida, where his right front inside heel was removed and repaired by Tom Curl.

Since then, Big Brown has been training and racing on a designer adaptation of a Thoro'Bred racaing plate that is glued on his foot without nails. The Yasha shoe system is like an orthotic insert between the shoe and the foot. One density of plastic, similar to the gasket that holds your truck's windshield in place, circuits the shoe and holds adhesive in place. Another density is a thick block pillow on which the remains of the heel sits as it grows out. Big Brown raced successfully in these shoes, winning the Florida Derby, Kentucky Derby and Preakness Stakes.

Note: in the "combi" Yasha paradigm, the plastic coats the foot surface of the shoe and acts like a dual-density rim pad. Some Yasha shoes have dual densities for different parts of the foot. Big Brown's shoes do not look like this.

"He doesn't even need the shoes anymore," McKinlay said today. "He could be in a regular shoe now."

My first thought was that a crack had developed at the hair line above the patch because of the stress from the material as the colt pounded down on the heel but Ian assured me that was not the case. "It's back around a little ways toward the heel," he said, "but not near that area. Besides that heel is all grown down now."

Many reports state that the crack has been "patched" but that is not the case. The crack has been cleaned up and treated with drying agents to dry it out and allow drainage of any infected area inside the crack. Then it was laced with the sutures as illustrated in the video posted on this blog last night (scroll down to May 25 video post to see that technique illustrated).

"As soon as I tightened it down, the foot started to cool out," Ian said. "Call me Wednesday to find out how it went."

Ian will check Big Brown again on Wednesday and decide what the next step will be in, in terms of replacing or relocating sutures, covering the crack with hoof wall adhesive, etc. The horse would then have nine days to train up to the mile-and-a-half Belmont.

In an email just received this evening, Ian gave an update: "By the way, his foot went cold within five hours of lacing him up, couldn't ask for more than that."

Nike Signs Big Brown to $90 Million Horseshoe Contract: Onion Makes Light of the Triple Crown Hoof Madness

I'm sure that The Onion's writers thought they were making all this high-tech horseshoeing stuff up; little could they know that the technology they describe is available...yet Big Brown wears a stock out-of-the-box shoe that is customized into the "designer model" Yasha cushion-heel prototype.

Big Brown Really Does Have a Quarter Crack This Time

According to Ian McKinlay on Sunday night, this horse's crack would be similar to the one that Big Brown has.

It's 12 days to the deciding race of the Triple Crown. We are on the verge of possibly the first Triple Crown winner since Affirmed in 1978. How wonderful it would be to have a new racehorse hero.

But...reports coming out of Belmont Park tell us that Big Brown has developed a quarter crack that is being disinfected and will be patched by specialist Ian McKinlay later this week when it is dry.

Hoofcare and Lameness received verification this evening from Ian McKinlay that the news is correct. Ian has posted some photos of the type of minor crack that Big Brown has on his web site for his Yasha shoes.

The irony here is that it was reported back in the winter months that Big Brown was suffering from quarter cracks on both front feet, when he actually had wall separations. This time, he really does have a quarter crack, apparently.

There are all sorts of hoof cracks and some quarter cracks are much worse than others. Some are painful for the horse while others are not.

A true quarter crack is a fracture in the hoof wall, much life a painful vertical split in your fingernail. Imagine how painful that split would be if you had to bear your weight on it!

The word "patch" or "repair" in conjunction with a quarter crack is a bit of a misnomer. The word "stabilize" would be more apt. The goal is to prevent shearing movement between the two parts of the hoof separated by the crack. Some people lace the crack to stay open a small bit so the coronet (hair line) stays at its normal angle while others lace it up very tightly to prevent any movement at all. Most decisions are based on two factors: the severity of the crack and the risk of infection.

In all cases, the horse is evaluated for its individual suitability to treatment. Some horses are very sensitive to hoof pain. Some have damage to the coronary band. Some have old chronic cracks that reappear. And some have infected quarter cracks, which cannot be patched until the infection is gone and the fissure is "dry". The age of the horse also affects the treatment plan.

Big Brown is in good hands and we all know that some horses have run--and won--with quarter cracks patched as little as a week before a big race.

Remember: Ferdinand won the 1987 Breeders Cup Classic with his foot patched for a quarter crack. He slipped by Alysheba to win.
