St. Croix's Street Sense: Farrier Says Derby Winner Was Shod with Mustad Family Shoes

This just in from Mustad, via press release:

Veteran Horseshoer Richard McChesney shoes his second Derby winner

FOREST LAKE, Minn. – May 15, 2007 – Babe Ruth had his bat, Michael Jordan had his high-tops, and now Street Sense, winner of the 2007 Kentucky Derby, has his shoes.

For the greatest American horse race, Street Sense – and his Shoer Richard McChesney of Mt. Washington, Ky. – trusted his hooves to St. Croix Forge’s Aluminum Racing Plates and Capewell nails from Mustad Hoofcare Center, the hoofcare people.

McChesney has been shoeing horses for 39 years. He has shod two Kentucky Derby winners: 1990 Unbridled and now, 2007 Street Sense. “It’s taken me 17 years to come up with a second Kentucky Derby winning horse,” says McChesney. “But there have only been 133 Derby race winners, and I’ve done two of them, which makes me feel good.”

He switched to St. Croix Forge shoes a year and a half ago, when he decided to try St. Croix Hinds, because “the samples were a little beefier, with room for extra nails,” he says. “You can put four nails right close together, and it seems to hold better. It eliminated problems so well in back, I decided I might as well use them on the front.”

“Street Sense’s come-from-behind win in less-than-ideal conditions speaks to his championship spirit, assisted by Richard’s horseshoeing skills,” says Mustad Hoofcare Center President Carlos Xifra. “We salute them both, and are very proud that Richard trusts our products for the most celebrated American horse race, the Kentucky Derby.”

McChesney replaces shoes once a month on his horses. Street Sense will run the Preakness Stakes May 19 wearing the same St. Croix Forge shoes, secured with Capewell nails.

People News: Get Well, Manfred!

Put your hand over your heart today (Tuesday, May 15) and think of our friend, Manfred Ecker, the original farrier at Rood and Riddle Equine Hospital's podiatry clinic in Lexington, Kentucky. Manfred was hospitalized a few days ago with a heart problem and will be undergoing a "procedure" at the University of Kentucky's medical center today.

I'm sorry to say that I have hundreds of photos of Manfred's exquisitely-crafted shoes and braces and tools, but this is the closest I could come to a photo of Manfred himself. I remember this day very well: a big Belgian pulling horse (foundered, of course) was in the clinic for shoeing. Manfred fired up the beautiful stainless steel forge and before long he was striking for Aaron Gygax (shown here on left), as they went to work creating handmade shoes for the giant horse. On that day, there was no glue, no high-tech fiber and no support material in sight, just two highly skilled farriers doing the job as farriers have for hundreds of years. What impressed me was how easily they switched gears--or centuries--in their work.

We're thinking of you today, Manfred.

Sue Dyson: More Information on Collateral Ligament Injuries in the Foot Follows Up Paper in Our Journal

This image from the journal article illustrates the telltale bump on the coronet that indicates a collateral ligament injury. However, Dr. Dyson warns that such visible signs are evident only in a percentage of cases. She recommends scintigraphy or MRI for identifying ligament damage in horses that illustrate specific lameness behavior characteristics.

Sue Dyson's article "Desmitis of the Collateral Ligaments of the Distal Interphalangeal Joint" was very well-received when it was published in Hoofcare & Lameness #79. While it is often difficult to definitely prove that collateral ligament (CL) injury is the sole cause of lameness, particularly in sport horses with degenerative joints and possible multiple foot problems, the good news is that horses do tend to recover from CL injuries.

Recently Sue shared with me her newest paper, which is a retrospective of more than 200 horses that had been diagnosed with lameness related to collateral ligament injury in the foot.

Among the many key points were that there was rarely any outwardly visible sign of injury not could the injury site be palpated or manipulated to induce or replcate the lameness. Trotting in circles on a hard surface was the ideal test. Only occasionally was heat or swelling present. While the injury has now become a common diagnosis for hardworking event horses and jumpers, it may be common in other sports as well.

The horses fell into three groups for comparative study of their diagnostic images, histories, and follow-up, when available.

In a group of 109 selected horses studied for comparison, the medial ligament (73%) was more damaged than the lateral (27%) one; the damage to the ligament was visible on MRIs of all 109 horses. One third of the horses from that sector of the study returned to work. These horses were identified as having lameness caused directly by injury to the ligament, and no other known cause of lameness.

A second group of horses had collateral ligament injury as one of multiple lameness disorders affecting the horse's soundness; these horses had a much poorer prognosis.

A third, smaller group of horses had problems with the ligaments at the point of origin or insertion, but 55% returned to full athletic function.

One of the points made in the paper that is very interesting is the higher incidence of bilateral collateral ligament injury, although the medial is still the more severely affected, in most cases.
A telltale sign of common CL injury in the foot is when the horse is more lame on the outside leg when trotted in a circle on a hard surface.

Whenever possible, Hoofcare & Lameness tries to keep readers up to date with newer research by our authors.

Sue Dyson is a consulting editor of Hoofcare and Lameness and generously shares her articles and photos and cases with us. In Hoofcare 80, she addresses the dilemma of lameness examinations on horses with multiple limb lameness, and suggests guidelines for sorting out horses that are two-legged, three-legged and even all-legged lame.

She is also co-author, with Mike Ross of UPenn, of the reference book Diagnosis and Management of Lameness in the Horse, sold through Hoofcare Publishing.

Plastinate: A Funny Name for a Fascinating View of Soft Tissue, Horn, and Bone

If you have visited a Hoofcare and Lameness trade show booth at any of the conferences this winter, chances are that you saw our display of plastinated samples of hoof tissue. If you haven't been to our booth, perhaps you have been to the highly successful (and somewhat controversial) museum exhibit called "Body Worlds," which also uses the plastination process to preserve body tissue. While we can be forgiven for studying closeup hoof tissue, the jury is still out on the ethics of human tissue manipulation.

We are working on bringing Dr. Christoph von Horst of Germany to the USA to share his delicate and precise representations of the hoof. Best guess is that he will be in Palm Beach for the laminitis conference in November.

In the meantime, Hoofcare and Lameness will facilitate orders for Dr von Horst. Each tissue sample is, of course, life size and sandwiched in inch thick Lucite. The sample becomes a living study object but it also is a work of art, and the play of light through the hoof tisue is dazzling.

One visitor to our booth at the AAEP convention was so enchanted that he offered to buy the entire display!

Each sample is treated to resist light damage and will not fade. The cost on most is around $200 including air shipment from Germany. I will try to mount some more images to share them with you, but please contact Hoofcare and Lameness if you are looking for a unique gift, award, trophy, or a real treat for your own study of the hoof. Navicular damage and P3 rotation samples are available but sometimes are in great demand and have a longer lead time.

What's the Antithesis of Natural Horsemanship? Meet No Horsemanship: Robotic Horse Training on a Sanitized Track

Call this the round pen backlash. Or high technology's answer to the average human's inability to train a horse. Several sources on the web have pointed me to a web site for what appears to be an Eastern European group that is promoting horse training systems that remove the influence of humans from the conditioning process.

Did you ever wonder what Disney World did with ride parts when they go through periodic renovations?

Kurt Equine Systems of course would appeal to a trainer who has more horses than exercise riders. Or someone who needs to condition multiple endurance horses but simply does not have the time to get them all ridden. There are also problems with weather and reliable help and many other variables in training that can make you dream of a "system" that would get all the horses moving and know when to quit.

Watching this video, I thought I was in a bizarre futuristic equine science fiction film. Dr Who goes to the racetrack? But the racetrack has been sanitized, and the only people in sight are in the control room--or are those robots, too?

The web site promo doesn't give many details; it tells us that these systems work for either horses or camels, so that is a broad hint to me that this prototype has been installed in the Middle East, possibly in Qatar, Saudi or The Emirates, although I think if it was in the UAE I would have heard about it. Someone would have called me from the World Cup back in March and said, "You MUST see this!"

I present this to you only as a wonderment. No comments, just wonderment. I knew when I posted the video of the Seawalker system for hoof rehab that someone would have to top it. And this is way over the top!

For the time being, I think exercise riders still have job security but if Todd Pletcher's string gets much larger...

Pergolide Cleared for Equine Veterinary Use by FDA

This announcement just in from the FDA:

May 11, 2007

CVM Working to Address Concerns about Supplies of Pergolide for Horses

The Center for Veterinary Medicine (CVM) is aware that veterinarians and horse owners are concerned about the issuance of an FDA Public Health Advisory (PHA), www.fda.gov/cder/drug/advisory/pergolide.htm, detailing the removal of pergolide products from the market. Pergolide, a drug used to manage the signs and symptoms of Parkinson’s disease in humans, is being removed from the market due to concerns about cardiac side effects.

CVM recognizes that veterinarians are prescribing pergolide for the treatment of Cushing’s Syndrome in horses. Veterinarians have been prescribing the drug under the provisions of the Animal Medicinal Drug Use Clarification Act which allows veterinary practitioners to prescribe approved human drugs for “extralabel” use in animals.

FDA is working with the sponsors of the approved products and all other interested parties to ensure that pergolide remains available to treat Cushing’s Syndrome in horses until a new animal drug application is approved for that use. This includes trying to make the approved product available through veterinary distribution channels and exercising enforcement discretion as appropriate over the pharmacy compounding of pergolide. Bulk substance used for pharmacy compounding should be labeled for “animal use only.” All pharmacy compounding must be done under a valid veterinary prescription to treat an affected horse.

Although the sponsor has stopped marketing pergolide for human use, CVM will also work with sponsors who are interested in seeking approval of a new animal drug application for the use of pergolide to treat Cushing’s Syndrome in horses.

For more information, contact Christopher Melluso, DVM, at Christopher.Melluso@fda.hhs.gov or (240) 276-9065.
