A Slice of Life: Behind-the-Scenes of Equine Anatomy with Dr. Christoph von Horst



Suppose you could suspend the animation of a bird or a fish or a horse...by preserving its anatomy in whatever angle or gesture or exposure you wished. That's the power that Germany's Christoph von Horst wields in his plastination laboratory.

Everything that was once alive not only lives again, but lives forever. It may no longer be living and breathing, but it's catching light and revealing its form to anyone who cares to have a look. And it has taken on an artistic, minimalist power.

Dr. von Horst's company, HC Biovision, is the world's leader in preserving anatomical specimen for educational and exhibition purposes. We are fortunate that he finds the horse's foot especially fascinating. He has been encasing microscopically thin slices of hoof tissue in Lucite for several years now, and has created a portfolio of hoof pathology to rival any in a museum.

Dr. von Horst will visit the USA this month; he will be helping Hoofcare Publishing introduce a new collection of plastinated hoof tissue specimen at the International Equine Conference on Laminitis and Diseases of the Foot in West Palm Beach, Florida this weekend, October 29-31.

He visited previously this year to speak at the international plastination conference at the University of Toledo and the annual convention of university veterinary anatomists at Cornell University.

Keep a hoof in your pocket; this new technique, called the "basic hoof" is impregnated with plastic but not cased in Lucite. Basic hooves cost only $50US (plus shipping) and will fit in your pocket. No two are alike!

Each plastinate is treated to resist light damage and will not fade. The cost on most blocks is $200. Most are about an inch thick and will stand up on their own.  But relief "basic" hooves start at $50--without plastic casing, just plastic impregnating the hoof tissue--and the "sheet", or thin plastic casings are $95 each.

Plastinates have many applications in the way that professionals interact with each other and with clients. On another level, they are used in anatomy education and on still another, for corporate use in detailing product or service details. When a veterinarian needs to explain why a horse with a fetlock problem might benefit from a course of Legend, this "slice" is an inexpensive, indestructible, reusable and portable tool for showing a typical fetlock to a client.

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 chronic laminitis samples are available as real models or in laminated poster form for reference, with areas of interest like the toe of a laminitic foot or a cross-section of a navicular bone and its ligaments greatly enlarged.  Sheet plastinates of the distal limbs of foals clearly show the growth plates and are perfect for explaining to horse owners why their horses need therapy sooner instead of later.

Dr Denoix's book is the perfect companion to plastinated specimen. Highly recommended for reference for academic or professional use of specimen or diagnostic images. It is simply "THE" book to have on hand. Call 978 281 3222 or email Hoofcare + Lameness to order your copy. A superb gift!

Vascular Plastination Casts of Equine Feet Ready for Shipping from Hoofcare Publishing

Note: these casts are temporarily not in stock. Because of the delicate work involved, they will be offered on a "special order" basis in the future. Please contact us to find out what the status of supply is at any time and we'll do our best to assist you. We do also sell beautiful posters of images of the blood supply

A plastinated "corrosion cast" of the blood supply in a horse's foot is created from the foot of a cadaver. Plastic is injected into the veins and, after removing the hoof capsule and processing away any non-vascular tissue, what is left is virtually a three-dimensional venogram. Hoofcare and Lameness is offering these for sale on a special order or as-available basis beginning in November 2010.




This over-exposed and light-enhanced image of a corrosion casting shows the delicate structure of the blood supply inside the hoof capsule.


Hoofcare and Lameness is now taking orders for full-hoof vascular casts, preserved by the plastination process of Dr. Christoph von Horst of HC Biovision in Germany. Dr. von Horst will be shipping these to the USA.

Some of you may have seen the half-hoof cast that has been on display in the Hoofcare and Lameness booth in the past. Everyone wanted it, but it wasn't for sale. A special-order trial set of casts was sold this spring, and new sets have followed.

The cost for a whole hoof corrosion casting in the USA is $352 plus $10 shipping. The casts cannot be shipped to foreign addresses.

The plastic is quite resilient, but these models should be handled with care. It's hard to imagine a better tool to explain why a venogram is needed, or as an asset to an anatomy class.

Photos can be shown to preview a model. They vary in the amount of detail and thickness in the hoof wall and sole; many have high detail in the coronary band papillae and digital veins.

One model that has been popular was affixed to a plexiglas base, making handling easier and insuring longer life. To view the underside, you can just look through the plexiglas. This is an excellent model for anyone who would use the model in a classroom setting.

A great variation exists in the amount of capillary tissue that has clung to the plastic through the mastication process. Models with more external capillaries are attractive to represent the whole hoof and the complexity of the hoof's blood supply; models with fewer capillaries allow better examination inside the capsule and more attractive light transmission for photography. The two models in the photographs with this article illustrate the extremes of these variations.

Partial models mimic venograms of horses with severe laminitis so that the owner can see in three dimensions what the damage to the vascular system might look like. This is just a gross approximation and is not meant to represent any particular case or stage of laminitis, but to illustrate where the damage might have occurred. These partial models are fragile.

Special orders can be arranged with Dr. Von Horst if you are looking for a vascular model of a certain type of foot. The casts available are a mixture of front and hind feet of average-sized, presumably healthy horses with no medical history available.

Please contact Fran Jurga at 978 281 3222 or email fran@hoofcare.com to inquire about the models. They are sold on a first-come, first-served basis. Pre-payment is required on all orders.

Hoofcare & Lameness has some amazing plastinated equine educational tools from HC Biovision.

These models are used in natural history museums, universities, veterinary hospitals, farrier clinics, and natural trimming schools around the world. They are permanent, low-maintenance, colorful, and durable preservations of actual tissue slices of horse hoof and limb tissue.

Equine Hoof Vascular Supply Plastination Cast for Equine Education is a 3-D Venogram

2 December 2009 | Fran Jurga's Hoof Blog at Hoofcare.com

A plastinated "corrosion cast" of the blood supply in a horse's foot is created from the foot of a cadaver. Plastic is injected into the veins and, after removing the hoof capsule and processing away any non-vascular tissue, what is left is virtually a three-dimensional venogram. Hoofcare and Lameness began offering these for sale on a special order basis on December 1, 2009.

This over-exposed and light-enhanced image of a corrosion casting shows the delicate structure of the blood supply inside the hoof capsule.

Hoofcare and Lameness is now officially taking orders for full-hoof vascular casts, preserved by the plastination process of Dr. Christoph von Horst in Germany. Dr. von Horst has agreed to ship these fragile wonders to the USA on a special-order basis.

Some of you may have seen the half-hoof cast that has been on display in the Hoofcare and Lameness booth for the past year. Everyone wanted it, but I couldn't sell it.

The cost for a whole hoof corrosion casting to the USA is $280 plus air shipping from Germany, which is probably about $20 since the cast does not weigh much, but does require a lot of protective packaging.

These models are fragile and little bits have been falling off mine for the past year but it still looks wonderful. Dr. Von Horst warns that this "shedding" of plastic particles is inevitable and unavoidable. It probably doesn't help that my sample travels from trade show to trade show and is handled a lot.

The plastic is quite resilient, but these models should be handled with care. It's hard to imagine a better tool to explain why a venogram is needed, or as an asset to an anatomy class.

If you would like to order a vascular cast or any type of plastination model, please contact Hoofcare and Lameness by calling 978 281 3222 or emailing fran@hoofcare.com. Advanced payment by Visa or Mastercard is required.

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.
