California Statistics Reveal Dangerous Trend in Hind Limb Breakdowns on Artificial Tracks

by Fran Jurga | 28 August 2009 | Fran Jurga's Hoof Blog

Data on racing breakdowns compiled by the University of California at Davis tracks the incidence of injuries, the seasonality of injuries and which limb is affected, among many other data points recorded. A publication of recent statistics presented to the California Horse Racing Board (CHRB) reveals a disturbing prevalence of hind limb injuries that led to the death of racehorses last year.

While the report is not available at present, the Los Angeles Times today reported that the study presented to the CHRB yesterday reveals that 19 horses died on California tracks from hind limb injuries in 2008, and that those injuries were split pretty evenly between left and right hinds. Only one horse died from a hind limb injury on a dirt track.

Breakdowns on the front limbs were somewhat more comparable between dirt and artificial tracks, but the artificial breakdowns still exceeded the dirt tracks: 74 horses broke down in front on artificial tracks while 59 broke down in front on dirt tracks.

Some people feel that this is an invalid comparison, and that trainers will often work a horse on a synthetic track that they would not work on a dirt track.

UC Davis examined 351 cadavers of breakdowns in its search for new insights into why racehorses are so susceptible to fatal injuries.

California has a 4 mm limit on toe grabs on front shoes and allows horses to run barefoot.

Death Under the Palm Trees: Breakdowns at Santa Anita

The Los Angeles Times and Paulick Report blog startled me this morning with updates on the number of horses euthanized at California's Santa Anita racetrack since it opened the day after Christmas.

In less than three weeks, seven horses have been euthanized. No word on how many others have been injured.

People are accustomed to the shock and horror of horses breaking down during races, but the reality is that more horses break down during early morning training sessions, as was the case on Sunday when two horses had to be euthanized.

No mention of the deaths is made in the news section or horsemen's notes on Santa Anita's web site.

The beautiful racetrack outside Los Angleles switched from a dirt surface to synthetic last year and experienced maintenance nightmares that caused the entire surface to be replaced with an Australian surface called Pro-Ride. The 2008 Breeders Cup was run on the Pro-Ride strip when it had been tested for only a month during the track's Oak Tree meet but the championship races went off without any fatalities. The major California tracks have all switched to artificial racing surfaces.

Santa Anita re-opened for its traditional winter meet over Christmas.

California led the nation in legislating lower toe grabs for race horses, along with the switch to synthetic surfaces that normally don't require traction devices anyway. Both moves were part of a concerted effort to reduce breakdowns and improve the safety of racehorses.

Oddly enough, the documentary/reality television show Jockeys was filmed at Santa Anita during the first weeks of the Oak Tree meet. It tracks the working and private lives of seven Santa Anita jockeys as they work toward the Breeders Cup. Presumably, the show, which premieres February 6 on Animal Planet, will give some interesting insights into the surface and the safety issues that were on the minds of jockeys and exercise riders as they rode over an untested surface.

Horseshoes + Racing Injuries + Video = Eclipse Award for the Louisville Courier Journal

The friendly smile of Churchill Downs horseshoer Sonny Broaddus brightened the Louisville Courier-Journal's otherwise sobering media-rich mini-site on injuries in Thoroughbred racing. The video-enhanced feature hit the web in mid-August and this week was announced as the winner of the prestigious Eclipse Award for multimedia.

Roll out the red carpet, here come the horseshoers.

When the Eclipse Awards for journalism and media coverage were announced this week, the Louisvillle Courier-Journal was in luck. Lots of luck, as it turned out: the winning feature section "Tragedy at the Track" on racing injuries was heavily laced with text, photography and especially video of horseshoes and the people who nail and glue them on the Thoroughbreds in Kentucky.

Graphic from the newspaper articles shows the effects of a toe grab when a racehorse stands on a hard surface, such as a concrete wash rack slab, or a paved road.

Written and compiled by Jenny Rees, Andrew Wolfson, and Gregory A. Hall, the series looks at racing injuries as a combination of the medical, mechanical and surface strains put on Thoroughbreds. It's an exciting combination of short and longer clips, including a short feature of Churchill Downs horseshoer Steve Norman and his entourage of helpers and apprentices on a hot August day.

Two special videos make a real impact on the newspaper's web site with the original stories. These are farrier Mitch Taylor's high-speed clips of horses running over different surfaces, wearing different shoes, with a simple measuring interface to show the difference in slippage and "snowplow effect" of changes in the foot's equipment and surface. I believe the high speed videos were shot by Scott Lampert and interpreted with his OnTrack analysis system.

Turfway Park Brings Back Toe Grabs on Hind Shoes After Eight Horses Break Down in December

You know those hind shoes you just threw away? Most of the shoes in this pile are old draft horse shoes with holes where removable calks could be applied for icy streets.

Just when you think you have things figured out...

Turfway Park in Florence, Kentucky runs Thoroughbreds over a Polytrack (artificial) surface that has been in place since 2005. After a new policy went into place in September that banned all but the flattest horseshoes on front and hind feet, the track was a model for reform and safety. Then the calendar turned to December: Turfway reported breakdowns that caused the death of eight horses, most of whom injured the left front leg.

Are the breakdowns related to the shoe changes? It's impossible to tell but one theory is that a slipping hind foot puts more stress on the opposite front. This is still a brainteaser, though, since the foot slips less in Polytrack than on dirt, such as you'd find at Churchill Downs.

Whether as a result of the breakdown or in deference to trainers wishes, Turfway has announced a policy change on shoes. While flat shoes are still required on front feet, toe grabs no higher than 1/4" are allowed on racing and training horses as of the first of January.

Here's the new rule:

Shoe Policy for Turfway Park

Effective January 1, 2009, the following shoe policy will govern racing and training at Turfway Park

Prohibited – Front and Hind
The following devices are prohibited both front and hind for racing and training at Turfway Park: turn-downs, bends, jar calks, stickers and any other traction device worn on the shoes of Thoroughbred horses.

Acceptable – Front
The following front shoes are acceptable for racing and training at Turfway Park: Queen's Plate, Queen's Plate XT, King's Plate, King's Plate XT, Fast Break, Speed Toe, and Outer Rim.

Acceptable – Hind
Hind shoes with a toe grab not exceeding one-quarter inch (1/4") shall be permitted for racing and training at Turfway Park.

Could the same shoe modification believed to cause injury and strain to the front legs actually be of benefit to the hind legs? Time for more research...and keep those new shoe designs coming.

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.

Still Thinking About Eight Belles? Leading Vet Hogan Suggests That Thoroughbreds Could Learn A Lot From Standardbreds

Dr. Patty Hogan in surgery

Carol Hodes, former media relations director for the Meadowlands Racetrack in East Rutherford, New Jersey, has posted a terrific interview with one of my favorite sources, Patty Hogan VMD, ACVS of the new Hogan Equine Clinic LLC in Cream Ridge, New Jersey. Two years ago, it was Hogan who testified against her veterinary brethren in front of the US Congress, and explained why she was not aligning herself with AVMA and AAEP political positions regarding slaughter of horses for meat. She didn’t like the idea of the whole horse meat slaughter industry and she gave poignant compelling reasons why. Congress listened. So when Eight Belles died tragically on the track at the end of the Kentucky Derby, journalist Hodes turned to Hogan for insight. Hogan, after all, is often described as the veterinarian who saved Kentucky Derby winner Smarty Jones, and she is the AAEP’s “On Call” veterinarian for some harness races that are televised. Carol’s entire interview with Hogan is posted on the HarnessLink web site in New Zealand. I highly recommend you follow this link and read the entire interview, but here are a few savvy comments from one of the best industry’s most independent thinkers and leading surgeons. This fall, Hogan will take over as head surgeon of the new Ruffian Equine Medical Center at Belmont Park, owned by IEAH, who also own 2008 Kentucky Derby winner Big Brown. Hogan: “I’ve seen horses break both ankles, in fact I repaired one this past week that came to me with a fracture in one hind leg, and I repaired it. When he got up, the other leg was broken. He was a thoroughbred with bilateral injuries, similar to hers, but not so severe. But that’s so rare. “For it to occur at the end of the race is very unusual. She [Eight Belles] must have had enormous fatigue, and that’s just puzzling. I know she was very well taken care of. I don’t think there was any smoke and mirrors there. That trainer [Larry Jones] is very honest. I don’t think the jock [Gabriel Saez] deserves the criticism he’s received at all.” “I’m sure genetics has played a role because [catastrophic injury] has increased in recent years. A lot of horses that have retired to be bred are not necessarily the most durable horses. They’ve hurt themselves after one or two races, and then they are sent to be bred.” From there, the interview heads in a new direction: why don’t Standardbreds break down the way that Thoroughbreds do? Hogan’s practice is evenly divided between the two breeds. Hode digs for some answers and Hogan supplies some good ones: “(Standardbreds) are being bred for speed and they’re getting sore, but they don’t kill themselves. The horses that end up going to the breeding shed, at least with the stallions, they’re the ones that have performed incredibly well and raced well.” “The prognosis is always better for standardbreds than it is for thoroughbreds. They always come back from everything. I definitely have a different set of prognoses that I can give for a standardbred vs. a thoroughbred even if it is exactly the same injury. It’s rare for a standardbred to founder or have laminitis as a result of having an injury in the other leg. With a thoroughbred it’s a huge priority.” Thanks to HarnessLink.com and Carol Hodes for the good work on this interview.
