Midnite: Mini's Back on All Four Hooves Thanks to Prosthetic Boot

Midnite is a miniature horse at a rescue farm in North Texas; he has lived his whole life with a deformed hind foot that is missing its coffin bone, according to the Rescue.

Have you heard about Midnite? His story is all over the Internet and television news shows today. This young miniature horse was a law-enforcement rescue case who hopped into Ranch Hand Rescue in South Argyle, Texas on three legs. He couldn't put his left hind hoof down because...well, because it just wasn't there.

Midnite may have come to a safe, new home, but even as he gained weight and his overall health improved, he wasn't cheering up and that was a challenge. Almost as much of a challenge as simple movements like laying down, or getting back up. Scampering around with the other animals in the paddock wasn't an option. He won over the hearts of everyone at the rescue farm, especially director Bob Williams, and Bob decided to see if they couldn't do something to help the little guy.

The first attempt was using a donated Soft-Ride hoof boot (thanks, Soft-Ride!), with its removable gel-pad orthotics. These rehabilitation boots are familiar to many Hoofcare and Lameness readers, and lucky come in a vast array of sizes--even tiny enough for a mini. They taped the boot on the stump of his pastern each day and removed it each night. The staff massaged him, and powdered his stub, and they learned a lot about three-legged horses, especially how they need to re-disribute their weight after a long time of not using one of their limbs.



Here's a YouTube interview with Lane Farr, designer of the prosthetic clamshell boot.

From seeing a bit of improvement with the Soft-Ride boot, the rescue team, led by Bob Williams, scratched their heads and wondered what a human orthotics designer might be able to design for a tiny artificial hoof replacement.

Enter Lane Farr, a prosthetic designer with a lifelong connection to horses and a way with carbon graphite and fiberglas and gel foam. Lane designed a prosthetic support device that he told me both allows the little horse to bear some weight on what passes for a hoof, and also transfers some of the weight to a passive load share state rather than the direct load straight down the bony column through the pastern.

Lane told me that there is no medical history on the little horse,but that the assumption is that the deformity is congenital--it was present at birth.

The support/weight transfer boot has been through a couple of stages of re-design and Midnite is now able to run with it on, as you can see in the AP video.

I thought you might like to see these other videos, which show the boot up close. I'd love to see the inside of the boot and the gel construction and will ask Lane and Bob if we might get pictures of that. They're both busy with reporters today, and I know how they can be.

Hoofcare and Lameness apologizes for the ads on these and all videos. They are embedded by the hosts and they're just there, sorry. These television stations and media outlets are generous to allow Hoofcare and Lameness to embed the videos, or to post them on YouTube the way that Associated Press did. Many won't allow embedding at all, which is why many great stories can't be posted on the Hoof Blog. But for those who do work with us--the ads are ok, even though I will probably never need an orthodontist in Fort Worth! It seems like the least I can do for the privilege of sharing videos with you.

This short video has some good close-up views of the boot.

Finally, a big thanks, hats off and high-five to Bob Williams, the Board of Directors of Ranch Hands Rescue, Prostheticare, and Lane Farr for all their hard work on behalf of this little horse. I know some people say, "So what? Why bother?" but I would remind you that these are real people, without a lot of money to invest in a single case and who are pretty much self-taught, who took a risk and came up with a successful, low-impact way to help this horse.

What none of these videos tell you is that Ranch Hand Rescue could use your donation to help Midnite and all their other rescued animals. Here's a direct clickable link to their PayPal donation page. Please help them out!

It is true that with a $14,000 price tag, this clamshell design isn't going to sold every night on eBay, but this story has received more press than any story since Molly the Pony back in 2008, and I can tell you that that story had an amazing impact on the way that people think about going the extra mile and burning some extra brain cells before they give up on a horse.

I'd also like to thank Bob and Lane for taking the time to return my pestering calls when they have way too much going on already. Like me, they think you all, the readers of this blog, might be the ones who can make a difference.

Please prove them to be right.

Cheltenham's the Place to Be Today


Last year at Cheltenham, the celebrity riders, trainers and familiar faces got together and recorded a song about the race meet that they all love so much for a charity fundraiser.



In Gloucestershire, England they run a four-day National Hunt race meeting that is like no other in the world. It's like Saratoga on steroids: the best horses, the (hopefully) best weather, and a few hundred thousand of your very best friends all make sure that you have an unforgettable time.

Today, Friday, is the last day and it all culminates in the Gold Cup. Old rivals--and stablemates--Demman and Kauto Star may be eleven now, but they're heading out again. Kauto Star has won it twice. Denman won it once and was second twice. Oh, and there are some other horses in the race, too, like Imperial Commander, who beat both of them last year. (Denman was second, Kauto Star fell.) That these three Gold Cup winners could be back to challenge each other again is the flip side of the chronic unsoundness we take for granted in racehorses. These jumping horses, at their age, must have tendons of steel. The Gold Cup is three miles, two furlongs...with hills.

The sad thing is, this will probably be their last meeting. Safe run, you old boys!

Grayson Laminitis Research Funding Breaks New Ground: Richardson, Pollitt and Van Eps Join Forces for International Support-Limb Laminitis Prevention Study

Today the Grayson Jockey Club Research Foundation announced its selection for the 2011 round of equine research projects that will be funded.

Laminitis research figured prominently in the mix of subjects to be studied. In particular, two studies will receive support from the Lexington, Kentucky-based charitable organization.

The first covers the dreadful form of laminitis that led to the death of 2006 Kentucky Derby winner Barbaro. This will be a multiple-year study; "first year" refers to the funding applied for 2011. Andrew van Eps received his PhD at the University of Queensland in Australia by studying laminitis; his previous contributions have included the first studies of the use of cryotherapy to prevent laminitis.

Here are the Grayson descriptions of the new studies:

Laminar Energy Failure in Supporting-Limb Laminitis
Dr. Andrew Van Eps, University of Queensland--First Year
Andrew Van Eps BVSc, PhD, MACVSc, DACVIM
A frequent and disheartening result of injury repair is that the leg opposite the one injured develops laminitis. This is known as supporting-limb laminitis and is what eventually caused Barbaro to be euthanized. Although it is a common occurrence, the mechanisms of the malady have not been established.

This project is headed by a young researcher, but the co-investigators are world renowned Drs. Dean Richardson and Chris Pollitt.

Professor Chris Pollitt BVSc, PhD
The project involves testing the hypothesis that supporting-limb laminitis is a result of reduced blood supply to the connection between hoof and bone (lamellar tissue). Further, that the blood supply in normal circumstances is encouraged by a regular loading and unloading of the legs and hooves (alternating which one is bearing the most weight). Injury to one leg interrupts that alternating pattern.

The researchers will test the hypothesis with a state of the art, minimally invasive technique known as tissue mycrodialysis in conjunction with three dimensional computed tomography to develop effective methods of preventing or minimizing lamellar tissue energy failure.

Comments in the Research Advisory Committee evaluations included “may well provide immediately applicable strategies to prevent supporting-limb laminitis” and “really nice grant, new idea about a devastating problem.”

Dr. Richardson received second-year funding for his ongoing study of laminitis:

Dr. Dean Richardson, University of Pennsylvania--Second Year
In Vivo Gene Transfer for the Treatment of Laminitis

Dean Richardson DVM, DACVS
This project seeks to develop a gene therapy approach to prevent laminitis in the contralateral hoof when a horse is being treated for a musculoskeletal injury. This, of course, was what eventually ended the efforts to save Barbaro and is a frequent threat to horses with hoof and leg injuries. The well known research team already has compelling preliminary data which encourages the hypothesis that use of recombinant adeno-associated viruses can be used as vectors to deliver a therapeutic gene (TMP-3) to the lamellar tissues. This is meant to inhibit the damage to the epidermal laminae without disrupting the normal hoof structure.

Another completely new study will begin at The Ohio State University, where the mechanism of cryotherapy in averting laminitis will be studied and, hopefully, recreated via pharmacology.

Digital Hypothermia in Laminitis: Timing and Signaling
Dr. James Belknap, The Ohio State University--First Year
The most recent figures from a study involving the USDA and State Veterinary Medical Officers project that at any given time laminitis affects 8 of every 1,000 horses in the United States. Based on the American Horse Council survey that there are 9.5 million horses in the nation, that would indicate 76,000 horses being affected at any given time. Of those affected, the USDA survey found that 4.7% died or were euthanized, or about 3,572 deaths from laminitis annually.

The authors of this project report that “an integrated research effort over the last decade has enhanced the current understanding of the pathophysiology of equine sepsis-related laminitis (one of numerous causes of the disease). This has mirrored progression of sepsis research in human medicine by moving from (an earlier) concept . . .to determining that a marked inflammatory injury takes place and is likely to play a prominent role in tissue injury and subsequent failure.”

However, there have been persistent failure of systemic therapies for organ/laminar injury in both human and equine medicine. One advantage laminitis presents is that it effects the hoof rather than visceral organs, lending itself to artificial cooling more readily. In a present project funded by the Foundation, digital hypothermia (cooling of the hoof) prior to onset of carbohydrate overload-induced equine sepsis resulted in dramatic decrease in laminar inflammatory signaling.

The next goal is to find pharmaceutical therapies which can accomplish the same without the cumbersome aspects of maintaining constant hypothermia to the equine hoof (hooves).

Equine Hoof Lameness, Laminitis Survey Results from British Study; Statistics Announced at National Equine Forum

Great Britain's Princess Royal addressed the National Equine Forum, where new statistics on horse health were presented.
The 19th National Equine Forum (NEF), held in Great Britain on March 8, 2011, was the launch pad for the results of the United Kingdom’s first public National Equine Health Survey. The event was attended by over 200 of the country’s most influential members of the equestrian industry, including NEF President HRH The Princess Royal, leading equine vets, international riders and trainers, equestrian society figureheads, business leaders and numerous members of the equestrian trade industry.  

Josh Slater, Professor of Equine Clinical Studies at the Royal Veterinary College and immediate past president of the British Equine Veterinary Association (BEVA), announced the results of the survey, which was pioneered by The Blue Cross animal charity and is supported by BEVA. The survey was conducted in November 2010.
The survey, which was pioneered by The Blue Cross animal charity and is supported by The British Equine Veterinary Association (BEVA), was carried out last November following two years of pilot schemes. The intention was to find out more about endemic non-notifiable equine diseases that have never before been recorded, such as coughs, skin diseases and lameness.

The results were announced at the Forum by Professor Josh Slater, Professor of Equine Clinical Studies at The Royal Veterinary College, who has been working with The Blue Cross on the survey.

Analyzed data from the study will be used to pinpoint current, non-notifiable healthcare issues affecting horses, ponies, donkeys and mules in the UK and is expected to break new ground for all of Europe as well.

Professor Slater explained that the survey should provide a future benchmarking facility for equine disease, welfare, standards of care and codes of practice and it has also confirmed the workability of an important template to monitor the serious threat of infectious and exotic disease in the future.

Laminitis cases still abound in Great Britain; this dramatic photo of a medial sinker from the case files of farrier Jim Ferrie FWCF is evidence of that. Jim provides consulting services at the University of Glasgow's Wieper Equine Hospital. (Jim Ferrie photo)
A total of 306 sets of records were submitted from 3120 horses in mainly private ownership, with a balance of representation from competition yards, riding schools, welfare charities and studs. A broad range of syndromes and diseases were assessed including colic, sarcoids, laminitis, wounds, dental issues, eye disease, lameness and weight issues.

Equine lameness statistics also figure prominently in the survey and show some variation from oft-quoted statistics about soundness problems in horses.

The results showed that lameness was the most common problem affecting horses (11% of horses surveyed) but that, unexpectedly, the foot was not the most common cause of lameness and that laminitis (3%) was less common than the 7-8% total that previous surveys had suggested.

Weight management was the next most common issue for horse owners, with 9% of horses recorded as overweight and 8% as underweight.

The new statistics are not far from those compiled in the study Equine laminitis in the new millennium: frequency, risk factors and assessing a potential new therapy by Claire E. Wylie et al, presented at the 2009 meeting of the Society for Veterinary Epidemiology and Preventive Medicine. Wylie found that  laminitis cases contributes to between 0.11‐28.57% of all equine visits analyzed by veterinarians who participated in her study, with a mean of 5.03% and a median of 3%.

The most often quoted statistics from Britain are from Hinckley and Henderson's 1996 paper presented at the 35th Congress of the British Equine Veterinary Association. (See Hinckley, K.A. and Henderson, I.W. 1996. The epidemiology of equine laminitis in the UK in the 35th BEVA Annual Congress Proceedings) That paper stated: From a study involving 113,000 horses in the UK it was estimated that the total prevalence of acute laminitis in the UK was over 8,000 cases annually, giving a prevalence of 7.1%.

Anyone who reads this blog knows enough to see little red flags popping up right away: there is a big difference in a study like Hinckley's that tracks cases of acute laminitis with a study of all cases of laminitis, like the National Equine Health Survey's, as reported by horse owners.

Many horses who suffer from mild chronic laminitis never get treated and may never even have an official diagnosis. (VetMoves photo)

Another study that is often quoted found a much higher prevalence of laminitis in Great Britain around the same time. Katz surveyed the health of horses at a large charity farm with a population of 1140 horses and ponies, and found an average of 148 episodes of laminitis (prevalence of 13%) occurring each year (between 1997 and 1999), involving 113 animals. (See Katz L, DeBrauwere N, Elliott J, Marr C, Pfeiffer D. The prevalence of laminitis in one region of the UK in Proceedings of the 40th British Equine Veterinary Association Congress.)

None of these statistics really add up. I have often heard Katz's 13% quoted as the nationwide prevalence of laminitis in the UK, when he was actually studying a population of horses that might rightfully be expected to have some sort of laminitis, related to age or neglect circumstances that required their removal to a charity farm. Were those horses a suitable population to use as a sample of the entire national population of horses?

Hinckley's statistics have always been shocking, considering that she was documenting strictly acute cases. Wylie's study, presented as a poster at the conference, does not specify how laminitis was defined. Having her statistic closely matched by the much larger population sampled by the National Equine Health Survey's is encouraging, if their parameters were similar.

That said, a lot depends on when a survey is conducted. Some years have much higher numbers of cases because of weather conditions that encourage grass-related laminitis. The problem with this study's result is that it is tempting to say that education, medication and horse-owner awareness are kicking in and more horses are avoiding laminitis than in the past. But then we immediately see that 9% of the horse population is overweight, and can only wonder if that figure is up or down from previous periods. If that number is down as well, then all the hard work of vets, farriers, feed companies and charities is having an effect and horses in Great Britain are in a lot less pain now than they were 15 years ago. Maybe.

Here's a brief slide show summarizing the National Equine Health Survey in Great Britain (click on right to advance slides):


An interesting extrapolation from the study is that 18 percent of the horses had a problem with weight management (either under- or overweight) vs 11 percent who had suffered from lameness. It's possible that the actual weight problem is much higher, since the statistic allowed the owner to judge his or her own horses' weight suitability.

To clarify the location of lameness: it may sound like news that lameness in the foot was lower than expected, but it should be made clear that lameness location was divided into three groups: foot (3.7%), non-foot (4.5%), and laminitis (3%). If you consider laminitis a lameness of the foot, the combined total would be quite a bit higher than non-foot sources of lameness. However, for the purposes of the study, the statisticians were probably trying to keep their categories separate.

Meanwhile, the British Horse Society reports that its 2011 Laminitis Conference, planned for the end of this month in conjunction with Dodson and Horrells, has been sold out and no more registrations can be accepted.

It's so difficult to compare statistics from different studies or to say that one is the definitive measurement of the most pressing equine health issues. It sounds like the new National Equine Health Survey could be on its way to being the one-stop source for horse health statistics in Great Britain. While it's easy to wonder about the validity of horse owners' judgments about things like their horses' conditions, it's more productive to congratulate the Blue Cross and BEVA for undertaking such a massive effort, and for getting it done. And, most of all, for making the results available to the public. Thank you!
