Greetings from the Gluegrass: Will Big Brown and Pyro Choices of Designer Footwear Turn It Into the Ken-STUCK-y Derby?

Risen Star and Louisiana Derby winner Pyro impressed a lot of people this winter. He did it wearing glue-on shoes called Polyflex, shown here on stakes winner Malibu Mint. Little Belle won the Ashland Stakes at Keeneland wearing these shoes last week; that's the track that Pyro will run on today. The shoes are more or less transparent, with a yellowish hue. They have a steel wire core which is shaped like the foot in a special mold, then urethane is poured in to the ideal shape. A steel toe insert completes the kit.

Glue-on horseshoes are the stuff of legend this year as at least two of the Derby favorites flaunt their footwear on the road to the Triple Crown.

In the Southeast corner, we have Big Brown, winner of the Florida Derby by a landslide in spite of recovering from heel wall separations in both front feet. The photo (bottom of this post) shows a typical injury of this type, usually caused by a subsolar abscess, trimming too short, or training and racing on hard tracks (or a combination of these factors).

Ian McKinlay, the New Jersey quarter crack specialist who repaired the detached wall on the first foot, said that the colt "is not a bad-footed horse" and just needed cushioning on the inside heel where an abscess had been. "Chances are, it will grow down, on both feet, and he'll be fine going into the future," Ian said yesterday. "His trainer knows what he's doing."

Ian's solution, which we hope to show on the blog, is a standard one; he says the injury is quite common among both Standardbreds and Thoroughbreds. He cleaned up the wall from the quarter back to the heel and put a gum rubber insert under the deficit. There's one heel nail holding the glued shoe from slipping, along with a copper clip (the PMMA adhesive sticks very well to copper) on the outside. The gum rubber material is like window caulking; it acts like a gasket. The glue-y shoe is a regular race plate.

(To read more about Big Brown's fancy footwork, see photo below and scroll down to posts and photos from earlier this week, marked April 8.)

And in Kentucky, all eyes will be on Pyro in the Bluegrass Stakes today. I didn't know until this week that Pyro won the Risen Star and Louisiana Derby wearing Curtis Burns' Polyflex all-urethane shoes, and he will apparently have them on today, as well,to run on Keeneland's Polytrack. Pyro's gluesmith is Steve Asmussen's regular horseshoer, David Hinton.

What's in a name? Polytrack seems to agree with Polyflex; you'll agree if you watched Kiaran McLaughlin's trainee Little Belle win the Ashland Stakes at Keeneland last Saturday, with Curtis's see-through shoes glued on her fast little feet.

And who gets the last word in this sticky story? That maven of the media, 2007 Belmont Stakes winner Rags to Riches. It seems R2R, who now resides at Ashford Stud in Versailles, Kentucky, was bred to Giant's Causeway last week. To celebrate her future marehood, farrier Steve Norman pulled her raceplates and replaced them with glueons which will stay on for a cycle or two. This is called "transitional shoeing" and is meant to encourage sole growth before she goes barefoot.

Traditionally, fillies and mares coming from the track have their shoes yanked off and they go straight to a barefoot lifestyle. This usually means gimping around the breeding farm for a number of weeks, since the feet are often cut quite short at the track, and the soles can be thin, until the feet toughen up.

One horse who I cannot imagine in gimp-mode is Rags to Riches.

Note: There are special shoes for gluing on racehorses, such as the Polyflex shoes or Sigafoos shoes, with cloth cuffs. Farriers can also glue on or glue-and-nail normal plates or shoes. There are some amazingly creative people working on these horses.

Thanks to all the farriers and trainers who contributed to this and other posts. I know they had a lot to do this week but most took the time to talk because these new shoes are past the "experimental" stage and are now considered creative equipment adjustments. We've come a long way.

This foot has been cleaned up after being blown out by a subsolar heel abscess, similar to the problem that necessitated glue-on shoes for Kentucky Derby hopeful Big Brown. Ian McKinley padded the exposed heel with gum rubber and glued window caulking like a gasket to hold it in so the area is cushioned. At this stage in the procedure, dead or hangnailish wall has been removed. This is NOT Big Brown, who is now well on his way in the healing process. (Ian McKinlay photo)

Big Brown’s Trainer Richard Dutrow Says Kentucky Derby Favorite Benefited from Expert Farrier Care Before Florida Derby

In this fun video, you can watch Big Brown gallop nimbly around the track at Gulfstream Park, winning the 2008 Florida Derby in near-record time last week while wearing glue-on shoes to help his front feet, both of which have suffered painful wall separations. What could he have done that day if he was 100 percent? Listen closely to the altered-lyrics of this familiar Jim Croce song; glue-on shoes are having their praises sung!

In an interview today with Hoofcare and Lameness Journal editor Fran Jurga, trainer Richard Dutrow shared some insights into the hoof problems that have been in the headlines lately.

If his horse Big Brown, owned by IEAH Stables Inc., can win the Florida Derby in near-record time from the outside post position with two hoof wall separations and special shoes glued on his feet, what might this horse be able to do if he was sound?

Dutrow said that when he arrived at his barn, Big Brown already had suffered one quarter crack, or wall separation, which was repaired in New York by hoof repair specialist Ian McKinlay. Later, the horse developed a second separation, in his “good” foot, after being shipped to Florida. This repair was handled by Tom Curl, a Florida-based hoof problem specialist who works with Ian McKinlay.

Among the horses on Curl’s resume are Belmont Stakes winner Touch Gold and famed leading money-earner Cigar. He also helped Afleet continue his racing career as he ran in stakes races with the first glue-on race plates back in the mid-1980s.

Dutrow consulted his calendar and said that it has been 40 days since Curl repaired the second foot. He said the first one is all but “history”, but on the second (newer) one, the problem is still visible above the glue holding on the shoe.

On his hind feet, Big Brown wears normal shoes, but with turndowns. A turndown is an exaggerated heel calk, formed by twisting the heel of the shoe toward the ground like a spike. Turndowns are not allowed in New York.

Big Brown will not be in the spotlight at Churchill Downs and Keeneland, where most of the other Kentucky Derby candidates are training.

Dutrow said that Big Brown will stay in training at Palm Meadows in Florida, almost right up until the Kentucky Derby. He will fly to Louisville on the 28th of April, according to Dutrow’s current plans. The Kentucky Derby will be run on May 3rd.

“I see no reason to move him,” Dutrow said. “He’s better off. I’m happy to get him ready right where he is. He’s happy here.”

Dutrow had nothing but praise for McKinlay, who he said has helped him with hoof repair situations before, and Curl, who is close by in Florida. He said that it was great to have experts like them to turn to. “This horse is dodging his problems,” he said. “And he’s going to keep doing that.”

Please click here to learn more about quarter cracks and see a short video from Big Brown's consulting specialist Ian McKinley of a horse with a quarter crack.

Note: Most of the information published so far on Big Brown's glue-on shoes are about their very high cost. I am not sure how or why that information was given to the racing press, or if it is correct and whether or not that price included the patching, which is an involved procedure. There are many expenses involved in treating a complex wall separaton or crack and in gluing on special shoes. What matters is what the care and shoeing and patching allowed the horse to do. I hope to have more details about the shoes to post shortly.

Quarter Crack Repair: Why Hoof-Impaired Athletes Like "Big Brown" Need Expert Care

Click on the "play" button to see a closeup video of a quarter crack and the initial stages of the repair process typically undertaken on a horse that needs to stay in training. This video is by Ian McKinlay of New Jersey, the quarter crack expert consulted for Big Brown's hoof problem. The horse in this video is NOT Big Brown and this horse's problem is not identical to Big Brown's!

A freakishly fast young Thoroughbred named "Big Brown" won the Florida Derby last week in spite of having "quarter cracks", or wall separations, in both front feet. The "cracks" were immobilized and he was wearing specially-adapted glue-on shoes (more on them later). From the email queries coming in, it seems that a lot of people are not really sure what a quarter crack is and what it means to a horse...especially a horse who hopes to win the Kentucky Derby three weeks from now.

First of all, please understand that a quarter crack is a specific injury to a foot, but that, at the racetrack, people often refer to multiple problems as quarter cracks. There are also bar fractures, heel cracks, subsolar abscesses that affect the wall, and other problems that are repaired with patches or glues and, in backstretch lingo, are called "quarter cracks".

This article refers only to the explicit condition of an actual crack in the inside quarter of the hoof wall. It is a common problem for racing Standardbreds and Thoroughbreds.

A quarter crack is literally a fracture of the hoof wall through the area of the hoof known as "the quarter", a point where, more or less, the geography of the hoof wall completes its arc around the toe, and the heel region begins. Sometimes you can see where angles of the hoof tubules change between the heel area and the radial part of the hoof. Some farriers refer to toe quarter, "the" quarter, and heel quarter as regions of the hoof wall.

Obviously, the regions of the hoof are much more delineated on a larger foot,and much more visible on a white foot.

Horses usually get quarter cracks in the medial (inside) hoof wall, as opposed to the outside wall. This is generally believed to be because of the shear forces of the horse's weight from above that is either abnormally high on the inside hoof wall, or because the foot is misshapen or weakened (known as "medial-lateral imbalance"). Conformation, improper shoeing, neglect and poor quality hoof walls are some of the causes of quarter cracks but experts say that they are often surprised when relatively normal hooves develop quarter cracks, possibly as a result of training or running over hard ground or changing gait so that suddenly more of the horse's weight loads the inside wall.

In simplest terms, a quarter crack is like a split fingernail that goes right up through the cuticle. Ouch! Now, imagine standing and bearing weight on that cracked nail. And then imagine running on it. And Big Brown has two of these cracks, although they are both in the healing process.

This, of course, is a vast over-simplification of one of the most complex disorders that can affect a hoof, and is meant only as an explanation for people outside the hoofcare field who are asking for more information about what quarter cracks are.

To answer one question: No! Cracks are not like musical notes, there are no half or eighth hoof cracks, that I know about, anyway! (Great question!)

Dr. David Hood of the Hoof Project, in his great little book "Building the Equine Hoof", offers a simple explanation: "Deep cracks occur when loads placed on the wall are greater than the structural strength of the wall. Inadequate blood flow, lack of balanced nutrition, or improper cornification can lead to a weaker wall prone to cracking."

The goal of crack "repair" is not to heal the crack but to immobilize it so that new growth can begin. A very serious crack will damage the top of the wall at the hairline, called "the coronet" (crown of the hoof). This is the area where new growth starts, and scar tissue in the coronet will prevent normal growth. Sometimes the wall that grows down from the cracked hoof is a different consistency and the zone is always in danger of a repeat fracture.

You'll notice on the video how soft the hoof wall is on this Thoroughbred, particularly in the detached heel area.

There's no doubt that these young Thoroughbreds have thin walls and that they are prone to these cracks. It's also pretty amazing how they heal.

As nasty as a quarter crack looks, an expert patch job can keep a horse running. And winning. One of the most famous crack repairs was on Kentucky Derby winner Ferdinand back in 1987 when he ran by Alysheba to win the Breeders Cup. Ferdinand's crack was patched by California horseshoer Buzz Fermin. The great Standardbred Nihilator was known to have raced wearing "mushroom" shoes, which remove pressure from the heel area.

NOTE: This is not a "how-to" video. The hoof walls on these horses are incredibly thin and the skill that it takes to properly drill through the wall without damaging live tissue is critical as is the exact amount of pressure used when lacing. Ian has been doing this for as long as I can remember and his skill is remarkable. Don't try this at home.
