Quality Road: Another Quarter Crack in the Road to the Derby

Tell me it isn't true: just when you thought it was safe to make him the favorite without an asterisk, top Kentucky Derby contender Quality Road has popped another quarter crack, this time in his right front.

Ian McKinlay reported on April 23 that he will be patching the new crack, which he says is minor, probably on Saturday, after suturing it today. The foot has been soaked and poulticed. The poultice was pulled on Friday morning, Ian said, after being applied to draw out any infection before the patch is applied. He will lace it with sutures later today. The same procedure will be used on the front foot that was used on the hind, which includes suture-lacing and an embedded drain covered by a patch.

Quality Road has had a quarter crack in his right hind foot for the past 26 days; the first crack opened during or immediately after his record-setting win in the Florida Derby at Gulfstream on March 28. The crack was patched in Florida and then dried out and re-patched with a drain when the colt returned to Belmont Park in New York under the care of trainer Jimmie Jerkens. Recently he has been training well and looked solid; plans are to ship him to Kentucky to race in the Kentucky Derby on May 2.

As of this morning, no announcement had been made to scratch the horse from the Kentucky Derby. Ian said he thought the horse would be able to make the race, based on other cases he has worked on.

Ian remarked again on the immense size of the three-year-old colt. "I'm six-three, and I look just barely over this horse's butt," he said. "And he's wearing a size five. He's a very, very big horse with a small foot."

That comment brought to mind a section on Ian's new video, From the Ground Up, which includes interviews with many trainers and horseshoers about foot problems and quarter cracks. Bob Baffert talks about the curse of the size-five foot, but then says with satisfaction that War Emblem was an example of a small-footed horse that overcame it and won the Kentucky Derby.

Video: Ian McKinlay's Quarter Crack Patch Drainage System

by Fran Jurga | 9 April 2009 | Fran Jurga's Hoof Blog



As promised, here's "film at eleven", just like on the evening news. Ian McKinlay videotaped the steps in the process he used to make a sub-p,atch drainage system for a quarter crack on Kentucky Derby contender Quality Road, who is now training at Belmont Park with trainer Jimmy Jerkens and will hopefully get a good work by this weekend.

PLEASE NOTE: The horse in this video clip is not Quality Road. It's his stunt double. Ian did do this procedure yesterday on Quality Road (scroll down for more on this horse's crack and patch over the past five days) but did it again on another horse in order to make this video so the Hoofcare and Lameness community could see both what he did and how he did it.

The drain is a precautionary step so that if the horse does have a flareup of inflammation, it can be treated. Please read the previous post about the technique, which Ian is not claiming to have invented.

I know that everyone will ask about the glue, it is the same PMMA-adhesive Ian has been selling, but in a new packaging system that will allow the user to cool it in summer to slow down the setup time so it can be shaped. Ian's Tenderhoof company sells sutures, drains and adhesive on his website. Click here to learn more.

Thanks to Ian for doing this; it's not easy filming a procedure in a racetrack shedrow with a moving horse, and that's just the beginning: editing and narrating can be even more work than the filming. I'm sure that this makes it much easier for everyone to understand.

Video: Update on Blood Test for Thoroughbred Breakdown Risk Markers, Researcher McIlwraith Interviewed

by Fran Jurga | 20 December 2008 | www.hoofcare.blogspot.com

Click on the screen to launch the video.

"How's his blood?" "Did you check her blood?" Questions like those might be the new mantra of racehorse owners when questioning a trainer before a race.

Colorado State University researcher Dr Wayne McIlwraith is bullish on the reliability--80% accuracy, he claims--of a blood test developed in his Equine Orthropaedic Research Center. This video is a good introduction to the concept of a blood testing protocol in the bigger picture of breakdown prevention.

The blood test will certainly not replace good horsemanship and monitoring of routine soundness and training issues, and there's no indication yet of what the test would cost, but this is a good news video for the holiday season.

Tests like the CSU protocol will do nothing to help accidents like the horrific death of a runaway filly at Aqueduct racetrack in New York last weekend. Nor will it help horses who go down from clipped heels or other stumbling upsets, starting gate mishaps or any number of accident-type situations that can happen in a race.

It's not clear how often racehorses would need to undergo the blood screening, or if McIlwraith would recommended that this test be a requirement for entry in a race. Breakdowns frequently occur during training sessions, although the public only sees the ones broadcast on television.

But I hope that the racing world does embrace this glimmer of hope, that it is found to be predictive, and that this is a legitimate step in the only viable direction left for racing: up. Up with horse welfare, up with safety, up with preserving the excitement and vitality of a great sport.

They should name it the Eight Belles Test. Passing the Eight Belles test would be a good thing.

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."

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.

Quarter Crack Repair: What Lies Ahead for Big Brown?

This video by Ian McKinlay explain the steps he goes through to "patch" a quarter crack so a horse can continue to train and race. Hit the "play" icon to watch the video; it is almost ten minutes long.

This video is part 2 of the first video we posted about quarter cracks back before the Derby, when there was confusion between wall separations and quarter cracks. We all thought Big Brown had quarter cracks until Ian clarified the situation. The first part of the video can be viewed here but it does not much, if any, narration.

The steps you see here are the final ones in the process. First the horse needs to be wrapped for a few days to draw out any infection and let the crack drain. Once the crack is clean, the repair process begins.

THE HORSE IN THIS VIDEO IS NOT BIG BROWN. This horse is being repaired for a chronic, pre-existing quarter crack that had become infected, not a fresh one like Big Brown's, but this will give you an idea of what process Ian McKinlay normally uses.

You will hear Ian comment on the prevalence of hoof injuries at Belmont this year.

By the way, Ian McKinlay is scheduled to be demonstrating his Yasha shoes at the University of Pennsylvania's Technical Horseshoeing Conference next weekend. Click here to go to yesterday's post about the conference.

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.

Quarter Horse Web Horseshoe Poll, Certification Article Published

The American Quarter Horse Association (AQHA) has been working with the American Farrier's Association (AFA) lately; the two organizations have an educational partnership exchange.

To that end, the December issue of America's Horse, the AQHA's promotional magazine, has an article about the conduct of an AFA Certification Testing Day in Oklahoma earlier this year.

I highly recommend that anyone who reads this blog find a copy of that magazine (it's not posted online, I checked) and read it. Pay particular attention to the last page, which shows a finished shod foot as presented to the examiner, who then reviews the clinches and explains what is wrong or right with each.

If you know anything about nailing horseshoes, it's interesting to see if you saw what the examiner saw.

My guess is that the nailing shown, imperfect though it may have looked to the examiner's eyes, is of a higher standard than most readers of that magazine would normally see. They might miss the whole point.

What I did find on the AQHA site was a poll of site visitors on the types of shoes their horses wear.

Barefoot was given as a choice, of course, but with the comment "barefoot is better" embedded in the survey question; roughly one-third of the site visitors agreed and said their horses were not shod. If that percentage is indicative of Quarter horse owners in America, then one-third will really disconnect from the AFA's nailing critique in the magazine.

More interesting, though, is that the AQHA listed Natural Balance as a separate category of shoes (bar/therapeutic? normal? sliders? Natural Balance?) To me, Natural Balance is a "normal" shoe.

I wonder how many owners are truly conscious that their horses wear Natural Balance shoes. Apparently five percent of the total is savvy to their brand name shoes, but the actual total might be higher. There are also Natural Balance lookalike shoes sold, and regular shoes can be re-shaped that way. And just to confuse matters, a horse could be shod with sliders made by Natural Balance or therapeutic shoes based on the Natural Balance pattern, as well!

Hoof boots were not listed as a choice. I've just heard about a sliding plate hoof boot that is coming to market; that should be interesting!

The poll is ongoing; check it out here. Results showed that only roughly 52 percent of the total horses were shod with normal shoes; 32 percent were barefoot, 5 percent wore Natural Balance, 7 percent had sliding plates, and 4 percent wore therapeutic or bar shoes.

Thanks to the AQHA for the educational initiative. It's a jungle out here, isn't it?
