Pollitt's Laminitis Images Have a New Look: MIMICS Software Goes 3-D

by Fran Jurga | 27 September 2009 | Fran Jurga's Hoof Blog

The cover of the Proceedings of the 2009 laminitis conference is a compilation of images of one foot of a chronic laminitis case from the University of Queensland in Australia. The foot's CT scans were converted to 3-D images using Mimics software and the expertise of Dr. Simon Collins of the Animal Health Trust in Newmarket, England. (Double-click on image for a larger view in a new window, but sorry that the web requires a low-resolution version of a very high-resolution form.)

When the end of the Fifth International Equine Conference on Laminitis and Diseases of the Foot comes, attendees might remember proportionately less of what they heard...and more of what they saw.

The heightened visual aspect of the exciting biennial conference, which will be held November 6-8 in West Palm Beach, Florida, may lie in the technology side of things, but the impact will be an eyeful that everyone can appreciate.

Leave it to Dr. Chris Pollitt (photo inset at left), assistant director of the conference, to bring the latest and greatest technology to the conference and to enhance his presentations.

The new software is called MIMICS; it is made by a Belgian company called Materialise NV. In a nutshell, MIMICS converts CT scans into three-dimensional forms. I've also seen it used to model a nasal cavity for a surgery case at Cornell's vet school, and for a comparative study of the soft tissue structures of equine feet at Auburn University. Dr. Pollitt says that MIMICS software is used extensively for human skeletal reconstruction surgery and prosthetic implant design and simulation.

"Suddenly I can 'see' an individual horse’s foot from all angles and can virtually dissect it on the computer monitor," Dr Pollitt wrote in the Proceedings.

MIMICS was introduced to Dr Pollitt and to the world of laminitis by British hoof anatomy researcher Dr Simon Collins. Dr Collins will be in Palm Beach to explain how he uses computer modeling in his work at the Animal Health Trust, where he collaborates with lameness experts Drs Rachel Murray and Sue Dyson. His images will be dazzling.

Dr Pollitt wrote in his introductory essay in the Proceedings, "Analyses of feet with chronic laminitis clearly show that distorted tubular hoof growth, lamellar wedge formation and solar loading of the distal phalanx are relentlessly destructive to bone. It behooves laminitis caregivers to understand the unmitigated, severe chronic process and develop proactive, early intervention strategies that will measurably arrest the process. MIMICS in the hands of laminitis scientists will aid this process."

Does anyone besides me see great irony in the way that Dr Pollitt over the years has created stunning visual images of the terribly destructive disease of laminitis? The quality of his images is always worthy of Scientific American or National Geographic and yet the subject is the disease we all dread. Thanks to his artistic eye we all know what laminitis looks like, even though it's the disease we'd most like to see wiped off the equine map.

NOTE: The deadline for registration for the conference has been pushed back to September 28th, since the mail has been so slow in getting the brochures and registration forms to everyone. Brochures were sent to all subscribers to Hoofcare and Lameness Journal. Also, a reduced rate for two-person registrations has been added. Visit www.laminitisconference.com for more information.

Wherever you are today, you are probably a long way from Stanley Vasques. But we all share an interest in horse hooves and their care. The only difference between most of us and him is that Stanley will wake up this morning and go to work in one of the most beautiful places in the world.

Stanley has been shoeing horses on the Hawaiian island of Kauai for more than 40 years. An article about him was published in the island newspaper, and I thought you might like to get to know Stanley and see a little bit of his world.

Click here to read an article about someone who will wake up in paradise this morning and go out and shoe some horses.

NEAEP Conference Preview: Patrick Reilly Will Report on Hoof Balance Studies

by Fran Jurga | 20 September 2009 | Fran Jurga's Hoof Blog

A last-minute addition to the 2009 NEAEP conference program is farrier Patrick Reilly from the University of Pennsylvania's New Bolton Center. Pat is filling in for farrier David Farley; both Dave and Pat are on the board of the new organization, which has both farriers and veterinarians among its members.

Patrick's lectures will include interesting studies and observations of hoof balance. In the video clip above, you will see that he has been documenting comparative solar forces on the hoof during athletic activities. This video clip shows the extended trot, which will be compared to a working trot in both a straight line as well as on a 20-meter circle. Pat also has some interesting measurements of the solar forces during jumping, and a comparison of differing density rim pads during jumping.

Patrick's videos and the use of pressure-sensitive data collection media give him some opportunities to make observations that bring up plenty of questions. For example, the same horse might land toe first in one gait (such as the extended trot), but land heel first in the regular trot. Also, a horse might land laterally on one footing, but lands evenly with the same trim on another.

Data from the hoof is transmitted directly, rather than through a pressure-sensing plate in the ground

The rider in the video is Patrick's wife, Karen; the flashy horse is her own; they just won a national young horse title last month. Congratulations!

Hoofcare@NEAEP: See You in Connecticut!

by Fran Jurga | 20 September 2009 | Fran Jurga's Hoof Blog

Don't call the office this week. Hoofcare and Lameness will be on location at the first-ever conference of the Northeast Association of Equine Practitioners (NEAEP) in Ledyard, Connecticut. The new NEAEP organization is kicking off its public persona with a double-barreled lecture series from Wednesday through Friday. One lecture hall is podiatry only, while the other covers a range of veterinary topics, including equine sportsmedicine.

Chances are, you'll find me in the podiatry lectures. The NEAEP has brought together a great group of speakers--including Robin Dabareiner, Melissa Fagerlin, Ian McKinlay, Scott Morrison, Scott Pleasant and Patrick Reilly--and filled a trade show with exhibitors.

I will try to keep the blog updated from Connecticut, but if you are planning to attend--and I hope you are--please stop by the Hoofcare booth in the trade show and say hello!

Registration will be available on site; details are at www.neaep.net. See you there!

PS I chose this nice old illustration as our company's booth logo for this event because it is so old. It dates back to a time when farriery was veterinary medicine, and the art of bandaging a horse was an example of one of the many arts of farriery. NEAEP is an organization comprised of both veterinarians and farriers (and other horse health professionals) and I am looking forward to working with this organization for many years to come!

Farriery Forensics: Who Shod the Wall Street Bomber's Horse?

The scene on Wall Street in 1920 after a wagonload of explosives became a horse-drawn bomb in front of the New York Stock Exchange. 

When the 9/11 tragedy happened in 2001, few people knew that it was not the first terrorist attack in lower Manhattan on a September day. Anarchists had tried it way back in 1920, and the only clue detectives had to go on in that case was a  horseshoe that survived the blast.

This is the story of that horseshoe.

Laminitis Prevention: Is Current Body Condition Scoring Irrelevant for Ponies?

by Fran Jurga | 18 September 2009 | Fran Jurga's Hoof Blog

A 9.2 hand, 12-year-old spotted pony named Firefly suffered from overgrown feet and laminitis in England in April 2007. She couldn't walk properly, but her owner refused to have her cared for, nor would she sign the pony over to the World Horse Welfare. A court case ensued and the owner lost her right to own horses for two years.

Here's Firefly in September 2007, on her way to full recovery and adoption to a new home. The research project funded by WHW at the University of Liverpool suggests that it is difficult to assign an objective body condition score to ponies using the system designed for larger horses.

Researchers at the department of clinical science at Britain's University of Liverpool, with support from the World Horse Welfare charity, presented new research at the annual convention of the British Equine Veterinary Association(BEVA) last week.

The question: how accurate is conventional equine body condition scoring for weight loss management when the equine being evaluated is an overweight pony?

The study, entitled Managed Weight Loss in Obese Ponies: Evaluating Weight Change, Health and Welfare, involved five mature, overweight or obese ponies and aimed to restrict their feed intake (on a dry matter basis) to 1% of body weight of a chaff-based complete diet for 12 weeks.

During this time the ponies' weight change, health parameters and behavior were monitored. All ponies remained healthy throughout the whole trial and an appropriate and safe rate of weight loss was achieved.

Clare Barfoot BSc (Hons) RNutr, registered nutritionist and the research and development manager for SPILLERS® (British horse feed company) explained: “Body weight decreased at a steady rate. However, despite significant weight loss, the body condition scores of the ponies didn't change. This highlights the concern that body condition scoring may not be the most effective way to monitor early weight loss in ponies.”

Even in this well-managed study, the feeding activity of the dieting ponies was decreased by 74 percent compared to ad libitum intake, highlighting the need for a practical feeding system that is both effective at managing weight loss but is sensitive to behavioral needs.

The WALTHAM® Equine Studies group was closely involved with this study as it has been with other groundbreaking work on equine obesity, such as showing that an obese body condition score was associated with increased insulin resistance back in 2003, and developing the cresty neck scoring system.

In response to the study, the research group is in the process of developing a new condition scoring system designed specifically for ponies. “This will involve validating the relationship between actual measurements of body fatness and the external appearance of the pony,” said Alex Dugdale, lead researcher for the study at Liverpool University.
