Plastinate Anatomical Tools Make Everything Perfectly Clear

by Fran Jurga | 12 October 2009 | Fran Jurga's Hoof Blog


It's Columbus Day, so you're invited to "discover" a new equine anatomy reference tool that will be a boon to your ability to creatively and constructively communicate with colleagues, clients and students no matter where you are.

Plastination is a tissue preservation process that gained worldwide fame this decade with the Body Worlds museum exhibit. The last I heard, Body Worlds was set to overtake King Tut as the most viewed exhibit in the world. It shows human organs and muscles preserved in various positions or medical conditions. But everyone I know came out of it saying, "Wow, if they could just do that for horses..."

And someone has. Germany's veterinary anatomy expert Dr Christoph von Horst has patented a process for preserving veterinary specimen in this way; he's done birds and rats and ticks and dogs. But thanks to the encouragement of people like Dr. Chris Pollitt and a loud cheer from Hoofcare and Lameness, Dr Von Horst is preparing spectacular hoof and distal limb anatomy specimen, and you end up with a hoof music video slide show on a day of discovery.

I remember for years how I struggled trying to learn anatomy from textbooks. I couldn't get the 3-D part. I believe that 3-D models from HorseScience are the absolute way to learn and study anatomy and that they revolutionized my ability to understand the hoof, to the extent I can say that I do.

These plastination models are a step somewhere between anatomy models and an x-ray. They come in different models, designed for more or less portability. Many will slip inside a briefcase or agenda planner...or even a jacket pocket.

I can't wait for you all to see these teaching aids. They are like living x-rays...in equally-living color! They are actual paper-thin slices of tissue vacuum sealed inside layers of crystal clear acrylic resin.

You can keep one in your briefcase, or collect a set to show different conditions like laminitis, a navicular cyst, ringbone, etc. or use them to show where a shoe will sit, where you will trim (or won't trim) or where an injection or surgery site will access a joint or problem.

This specimen illustrates ringbone quite clearly but, like most anatomy models, the medical history of the animal is not available for reference. (Dr. Christoph von Horst image)

The plastinate tissue is very clear and well-defined because it is paper-thin and light passes through, illuminating the details and edges of structures and their relative textures. (Dr. Christoph von Horst image)

The specimen come in two types: flat sheets, which are about 3/8" thick, or the block versions, which are about 3/4" to 1" thick. The blocks are stunning and look fantastic on a desk or bookshelf, particularly if there's a light nearby. They make a beautiful gift or presentation award.

Of course, no two are alike. Hooves are available in sagittal, coronal and transverse sections, with the vast majority being sagittal, since that is the primary view people are accustomed to using for reference.

Right now we even have a foal's limb and a huge draft horse lower limb with what Dr Von Horst labels as lymphangitis-type swelling. There's also a stunning example of pastern ankylosis.

Even a large joint like the hock can be encapsulated into a plastinate specimen. (Dr. Christoph von Horst image)


Also available are laminated posters of several popular types of distal limb and hock plastinates; you can write on the plastic, draw a shoe or cast on, or use the poster for teaching by asking students to fill in labels for specific structures. Plastic casts of the blood supply and plaster casts of hooves are available by special order.

The best news? Prices start at under $100, plus shipping, with the blocks selling for about $200 at the current exchange rate.

Be sure to visit the Hoofcare and Lameness booth at conferences this fall to see these amazing teaching and learning aids, or contact the office to arrange an order to be selected and shipped directly to you.

If you have trouble with my video widget, you can also view the slide show on Hoofcare's slowly-expanding video channel. The widget seems to be skipping over some of the images in favor of text slides.

Applied Anatomy: The Painted Horses as Teachers

by Fran Jurga | 30 July 2009 | Fran Jurga's Hoof Blog





How did we teach (and learn) anatomy before we had super-markers to paint directly on horses' bodies? I believe that this clever technique was popularized by American clinician Susan Harris in the 1990s, or at least she was the first to make an educational project out of horse-painting.

We've seen an expansion lately, in the art of painting on horses. Dr. Gerd Heuschmann uses the horse as a canvas in his terrific video, If Horses Could Speak, and there's a beautiful new book on the Hoofcare & Lameness list (ordering info below) called How Your Horse Moves that documents painted horses going through gaits and stretches.

The problem, of course, is that you can only suggest the surface structures, and so much lies beneath. And should you choose the skeleton or the muscles?

Nicole Rossa solved that problem by painting the muscles on one side and the bones and joints on the other. Nicole is an equine therapist in England who has written some interesting papers, most notably one on asymmetry of the pelvis in racehorses and the effect on performance. Now she has teamed up with horse insurance company PetPlan and is consultant to the most ambitious web site project in the horse health world, Yourstables.co.uk.

On second thought, don't click on that link. Yourstables.com is a distraction demon. It's an absolute vortex where hours can pass while you wander around inspecting the minute textures of the stable mats and what it says on the plaques of the walls in the office. You'll emerge hours later, blinking.

Yourstables is a setup for teaching horsecare through consulting professionals, with the guidance of eventing legend Lucinda Green as an avatar. A 3-D horse barn (British style) is equipped with the newest and best of everything. You mouse over items and navigate through videos and printable articles explaining everything from grooming to diseases. It's quite good and Nicole Rossa is the consulting therapist. This list video is an out-take from a video made for the web site.

Back to the painted ponies: I just have one question. Why stop with horses? Do dog health educators paint anatomy markers on greyhounds? Who wants to volunteer their Jack Russell or maybe a Pug to be anatomically decorated? Nicole Rossa might find some work on humans when Halloween comes around.

Heads up: How Your Horse Moves by Gillian Higgins can be ordered now. Super reference on anatomy, gaits, biomechanics, jumping, tendon function, back function, etc. All full color photography; most of the horses are anatomically enhanced and very nicely photographed. The cover does not do this book justice. Hardcover, 153 pages, indexed, 350 color photos. Intro by Chris Bartle and Bettina Hoy. I expect I will be seeing a lot of the photos in this book in other people's PowerPoints soon! The good news: $30 per book plus $6 per book post in USA, $13 per book elsewhere. To order call 978 281 3222 or email books@hoofcare.com.

NOTE: Gillian Higgins will be on the program at a conference with Dr Hilary Clayton February 13-14, 2010 in Grantham in Great Britain.

Australian Anatomy Animation: Tendons and Ligaments of the Distal Limb

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



People make a lot of jokes about "boning" up on their equine anatomy knowledge, but Australian researcher Jonathan Merritt took it to heart and dedicated himself to creating a three-dimensional model of the lower limb of the horse, on which he has applied the ligaments that hold the entire apparatus together and the tendons that move its parts. He applied them layer by layer so that you can see the enormous complexity of the segmented structure of the equine limb.

The technical definition of a ligament is an attachment between two bones; generally a ligament is in a position that will make use of its fibruous strength in just the right place and angle to stabilize a joint. Ligaments allow flexion, but prevent malfunction. Tendons, of course, are extensions of the muscles in the upper limb that move the joints in the lower limb.

Jonathan Merritt's PhD thesis at the University of Melbourne was on the biomechanics of the forelimb of the horse. The focus of the research has been the relationship between the dynamics of locomotion and the strains induced in the third metacarpal bone. Dr. Merritt's work includes being lead researcher in the study Influence of Muscle-Tendon Wrapping on Calculations of Joint Reaction Forces in the Equine Distal Forelimb in the Journal of Biomedicine and Biotechnology (Click here to read online.)

Here's his description of how the little video was made: "The models of the bones were created from real equine limb bones using in-house photogrammetric software that I wrote. The bones were imported into Blender, and the ligaments and tendons were modeled by hand. Finally, a custom RenderMan exporter script was used to export the models and camera animations to the Aqsis renderer."

Dr. Merritt has been very generous to post this video and others he's made both on YouTube and vimeo.com.

I don't know that you can or should download it and hope that no one will abuse his generosity in both posting the videos and allowing them to be seen in places like this blog. The right thing to do would be to bookmark the video, send others to watch it and send an email to him letting him know you appreciated his hard work.

Encouraging talented people like Dr Merritt to pursue further studies in equine biomechanics and anatomy would benefit us all. Thanking generous people like him can't be done often enough.

Click here to go to Jonathan Merritt's home page on YouTube.com; you can send him an email from there and also see some of his other videos.

Sport Horse Biomechanics DVD Rollout: "If Horses Could Speak"--Would They Scream "Ouch"? German Vet Thinks So.

by Fran Jurga | 7 April 2009 | Fran Jurga's Hoof Blog


The trailer for our new "If Horses Could Speak" DVD is in German with subtitles but the DVD we are selling has been re-engineered with an English soundtrack.

Enjoy this trailer for the feature-length DVD now offered for sale by Hoofcare Publishing.

What are the potential ill effects of training methods used for "sport" dressage vs the "classical" way of riding and training? Known for his campaign against "rollkur" (hyperflexion), Dr Gerd Heuschmann's If Horses Could Speak DVD goes even further in this dvd and condemns "modern" training and riding methods that he feels are damaging to horses, even though they produce an upper level dressage horse in a shorter time and the judges seem to like what he considers incorrect movement.

Warning: this DVD is graphic and sometimes even violent; at other times it is beautiful and poetic and the special 3-d animated anatomy graphics are spectacular, if all too brief. The scenes of an anesthestized horse being prepped for surgery may be upsetting to someone who hasn't seen it before and the DVD is not specific about the nature of the leg tendon or suspensory ligament injury surgery and how it is related to improper training or movement.

For all of you who ever thought of dressage as being akin to "watching paint dry", here's your wake-up call.

Specifics:75 minute DVD format in English • USA DVD format (may not play on all Euro systems) • "Starring" Dr. Gerd Heuschmann with commentary by Oberberieter Johann Riegler of the Spanish Riding School of Vienna and Professor Heinz Meyer and Peter Kreinberg, riding by Grand Prix rider David de Wispelaere, with introduction and epilogue by the esteemed equestrian historian Hans-Heinrich Isenbart and so much more. • Special effects and animation by Pixomondo • Produced by Isabella Sonntag and Wu-Wei VerlagPrice $60US plus $6 post in USA, $12 post to the rest of the world. (Companion book, Tug of War, is $25 plus $6 post.)

Click here for more information on ordering the complete 75-minute dvd with new English narration and/or Dr Heuschmann's best-selling book Tug of War. Alternately, call 01 978 281 3222 or fax 01 978 283 8775 with Visa/Mastercard information, send checks to Hoofcare Books, 19 Harbor Loop, Gloucester MA 01930, or email our office.

Click here to watch an interview with Dr. Heuschmann posted previously on The Hoof Blog.

Disclaimer: Opinions stated in the DVD are open to interpretation according to some anatomists and biomechanics experts. Trainers and riders and veterinarians and farriers and anyone who works around these horses shares their moments of pain and knows their athletic prowess. There are no easy answers and anyone interested in this area should follow the research of biomechancs leaders like Drs. Hilary Clayton and Jean-Marie Denoix as well as the equine spinal research of Drs. Rachel Murray, Sue Dyson or Kevin Haussler (to name but a few).

The Hoof Blog
tries to keep readers abreast of new developments in this area and they are coming along at a fast clip, which must be very encouraging for Dr. Heuschmann and others who have rattled a stick on the fence to get attention for the welfare of competition horses.

Please let me know what you think of this DVD after you have watched it. Whether you agree with this DVD or not, you will have to agree that the window is open to a new world of science and research and that Heuschmann's passionate work legitimizes and demands more of the new field of equine sport science. Thank you, Dr. Heuschmann.

Hoofcare 101 Part One: Anatomy Basics Refresher Course Video with Nate Allen



This blog is read by hoofcare professionals of all levels and stripes and ranks and religions. It is also read by hundreds of people each day who are just "passing through" and are interested in a specific aspect of the hoof, or maybe manufacture a product or are horseowners looking for a clue that will help a lame horse.

Farrier instructor Nate Allen of Allen Farrier Service in Juanita, Nebraska and Central Community Technical College in Hastings, Nebraska, narrates this and other videos in the series that I will be posting in short segments so as not to overwhelm you all. This project is made possible by support from the University of Nebraska and Purina Mills through the Cooperative Extension Service network of educational agriculture resource providers and eXtension.org, an educational partnership of 74 universities in the United States.

Note: if you think this video is too basic for you, be patient. The series has to walk before it can run, and I think it is a good idea both to review basic anatomy and learn the terms and principles that Nate Allen will prefer to use in later videos. Anatomy doesn't change and is not a creative subject, but people do approach it in different ways and educators tend to vary in the way that they stress the roles of different structures.

I should probably add that throughout these videos, Nate is sharing his own point of view on subjects like sole pressure, hoof expansion, the role of structures in hoof mechanism, etc. and I realize that many people do not share the tried-and-true farrier science approach. Again, these videos are what a mainstream, middle-of-the-road well-educated farrier instructor thinks people should know about hoofcare. He has put a lot of work into this project and deserves a lot credit and respect, whether you agree with him or not.

You could also download these videos and use them for educating horse owners, or run them on a loop at a trade show booth. You can't go wrong by starting with the basics...and no matter what people tell you, most of them can't find their way around the most basic anatomy diagram and have forgotten everything they learned decades ago in Pony Club or 4-H. Letting them watch this refresher-course video may save them a lot of embarrassment, and you'll be even more of a hero than you already are.

Congratulations to Allie Hayes of HorseScience

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

Congratulations to our friend Allie Hayes of HorseScience, who was recently inducted into the Horseshoeing Hall of Fame.

Allie's fame in the hoofcare world began when she retired from active shoeing in the 1980s, after a long career as a farrier here in Massachusetts. She was one of the first women to go through farrier school, and was challenged by instructor Bud Beaston to complete the course at his Oklahoma Farrier College. She met the challenge, and went on to do advanced studies with Dr. Doug Butler at Sul Ross State University in Alpine, Texas. And this was after she had finished both a Bachelor's and Master's degree in liberal arts!

Allie said in her acceptance speech that sitting in Bud's classroom was the first time that a lecture really hit home with her and meant something in her life.

In the mid-1980s, Allie's ability to shoe was limited by a freak accident on the job, and she switched her attention from shoeing to making educational hoof models. Her "HorseScience" business has expanded to a point where she is the world's leading (and almost exclusive) source of freeze-dried educational models, and she also supplies much more than legs. The models are freeze-dried in a monstrous freeze-drier machine on Allie's farm, a stone's throw from her wildlife rehabilitation and re-homing projects (anyone for a blind skunk or a one-winged crow?), her farm animals, and her how-many-are-here-today cats.

She's also well-known to FedEx, as vets and farriers from all over the country ship legs amputated from euthanized cases to her to be eternally preserved for further study. People must wonder...

As one farrier said in an email, "It's too bad Allie had that accident and had to stop shoeing, but it was a great thing for us that she started making her models!"

Allie gives clinics, lectures, and slide shows on the anatomy of the foot and lower leg and occasionally presents a museum-like collection of her most unusual specimen. At the Cincinnati conference last week, she casually pulled out a camel's foot, and mentioned a giraffe foot as well. Her show-and-tell discussions with farriers and veterinarians are legendary.

Needless to say, Allie is the first woman to be inducted to the hall, and it is a sign of respect for her that the living members voted for her to join them.

Allie has a hard time drawing the line between education and business and has not been utilized as much as a formal speaker and consultant, partly because her business keeps her so busy. If you are in the hoofcare industry, it is important to support Allie and HorseScience as she leads us all ahead on the road to understanding horses and their problems. She has enabled many people to "see" inside the horse and probably learn things they would not otherwise be able to comprehend. Allie Hayes is a unique treasure in the hoofcare world, and deserves this latest honor very, very much.

Allie makes foot and leg models like this one, which has magnetic bones that snap in and out.

HorseScience also makes hock and knee models, and specialized ultrasound interpretation models.

AAEP San DieGO Preview: Discover Plastinated Equine Anatomy at the Hoofcare and Lameness Booth

Posted by Fran Jurga | 15 November 2008 | © www.hoofcare.blogspot.com
This post contains an embedded multimedia file and may open slowly. It's worth the wait!

Your pictures and fotos in a slideshow on MySpace, eBay, Facebook or your website!view all pictures of this slideshow

At the 2008 American Association of Equine Practitioners Convention in San Diego, attendees will be able to meet German veterinarian and anatomist Christoph von Horst in the Hoofcare and Lameness booth. This will be the first time that equine plastination anatomical models will be shown in North America! The majority of the equine plastination models are of hoof tissue, but you will also see in this slide show a tissue slice from a horse's head.

Plastination is a preservation technique. You may have seen or heard about the blockbuster museum exhibit that has been traveling the world, called Body World. Dr. Von Horst is an anatomy specialist who uses the same procedure not to shock the public or create controversy, but to preserve delicate slices of tissue for intense study of equine anatomy.

Serendipitously, he has created hauntingly beautiful images and models that cross the line into art. His images of the hoof's laminae were selected for display this summer at the National Museum of Racing in Saratoga Springs, New York. Was it art or was it veterinary science? It looked like a spectacular sunrise coming up not over the curvature of the earth but the curve of the coffin bone!

Dr. Von Horst will be bringing some samples of his work in the form of both two- and three-dimensional models for sale. Many of his tissue extractions are cased in lucite for long-term preservation and study. I do not know what he is planning to bring but I know it will be a beautiful display--and turn our booth into a museum! You will be able to purchase examples that are for sale.

Be sure to visit www.plastinate.com to learn more about Dr. Von Horst and his work.

I know that many of Hoofcare and Lameness's subscribers and friends will be joining us in San Diego for the AAEP convention, beginning December 7th. There is a half day of lameness lectures each day, and a full day of farrier lectures on Wednesday, December 10th. Add those educational opportunities to the prospect of browsing through the largest trade show on earth dedicated to horse health products and services (you really can't see the whole show in one day) and you can see why this event is the one we have been waiting for through all of 2008.

Having Dr. von Horst visiting with hoof and anatomy afficianados in our booth each day will be a huge bonus. Over the next three weeks, this blog will be featuring many of the speakers and exhibitors and new products that will be making the trip to San Diego. Just a few of the speakers familiar to Hoofcare and Lameness readers are vet/farrier Dr. Hans Castilijns from Italy, farriers Dave Duckett FWCF and John Suttle, and hoof repair specialist Ian McKinlay. (And that is just the tip of a wonderful iceberg!) We all look forward to seeing you and sharing this great experience with you.

Please download and study the AAEP Convention web site's schedule of the veterinary and farrier programs. Click here to preview the trade show, which will be open all day, Sunday through Wednesday.

Is this a natural swim-trim?


hippo feet, originally uploaded by moocatmoocat.

This was a hard photo to find; hippos are usually standing on their hooves. Hippos are of course known as "river horses" and this shot shows you why.

I wonder if anyone has studied the hoof wall composition of hippos; these hooves are in the water virtually 24/7, although not always in the nonweightbearing state.

Is it someone's job at the zoo to trim these hooves?
