AAEP Convention Report: Digital Extension Device Details from Hans Castelijns

And now for something completely different: German farrier/veterinarian Hans Castelijns gave several lectures at the 2008 American Association of Equine Practitioners Convention in San Diego, California. In a special session on lameness in the foot in Monday, he presented a tool that has, as yet, not hit the radar of American-style lameness diagnosis.

Castelijns is a referral vet/farrier and runs a rehabilitation farm in the Tuscany region of Italy, when he's not harvesting his olive groves or traveling the world as a lecturer and thought-provocateur.

His tool is a multi-level aluminum-encased disk that the horse stands on; the top surface is covered with a non-slip pad. A long lever arm extends from the center of the disk. It cranks the disk up to displace medial or lateral, toe or heel, regions of the foot, to test for discomfort, or perhaps more precisely, to gauge the horse's range of comfort. The horse protests when too much torque is placed on the foot, indicating ligament pain or general intolerance to uneven weightbearing.

Closeup view of the digital extension device: the center plate swivels quite elegantly so the operator can move around the horse while the horse stands still and does not have to have its foot repeatedly placed on and off the device. The opposite leg is still held up by a helper. (Loic Entwistle image)


Swiss farrier Bernard Duvernay demonstrated the device at the wonderful Luwex HufSymposium in Germany in 2006.

The lever arm has an angle gauge and a level at the end, so the operator can say, "Before we trimmed him, he had a medial intolerance at x degrees. With this new trim, he showed no intolerance at all."

The tool is a massive sophistication of the basic lever test for navicular pain; veterinarians formerly stood horses on a board and lifted it, higher and higher to extend the coffin joint and stress the navicular zone, including the deep digital flextor tendon and the navicular ligaments, while an assistant lifted the opposite foot (see photo below). Horses with navicular pain shivered their upper leg muscles, jumped right off the board or buckled backward. The test was often dangerous for all involved; sometimes diagnostic tests would try to lift the foot from the side to elevate the lateral side of the foot, so that pain in the collateral ligaments might be identified.

French veterinarians with a customized board for navicular zone reaction testing; one end has been covered with a non-slip pad, while the operator end has a handle for pulling up. Notice that the board is long enough to keep the diasnostician somewhat clear of the horse in case it rears up or jumps off.

While digital extension tests with a board may not be very accurate in pinpointing the source of pain, they can be helpful, particularly in the field, and they are useful for before and after illustrations of horses reactions pre- and post-shoeing or trimming or surgery. Castilijns has developed a protocol for the use of the more sophisticated tool and also has pinpointed areas that he feels are sensitive to specific elevations.

Castilijns's paper is published in the official Proceedings of the AAEP Convention. An older paper on the device is published in the English language section of his excellent web site. Click here to read the older paper.

The device is sold commercially in Europe.

Friends at Work: Meet Brian Cameron, Award-Winning National Senior Apprentice Farrier in New Zealand

by Fran Jurga | 4 December 2008 | www.hoofcare.blogspot.com

When New Zealand apprentice farrier Brian Cameron puts down the last horse's hoof at the end of a day of shoeing, he puts his own foot in the stirrup and starts schooling his show jumpers.

Brian was recently awarded the title of National Senior Apprentice for his achievements with his mentor, senior farrier Jock Good.

This article is not just a good view of a hardworking young farrier who wants to excel; it offers insight into the New Zealand system of farrier training, which I have always thought was very good. THey not only have a system for apprentices with college training, but also offer continuing education courses with credits for working farriers--or at least they did when I was there.

You might see Brian Cameron in the farrier competition tents soon--or in the show jumping ring. He seems set to succeed in both arenas!

Click here
to read about Brian and the farrier training system in New Zealand, as published today in the Taranaki Daily News in New Zealand..

Brian seems to be following in the hoofprints of show jumper Bernard Denton, who didn't make the Kiwi show jumping team for Hong Kong on his high-flying jumper Suzuki, but as a consolation prize was chosen as the team's farrier!

What I Was Going to Write About Today

For the past few weeks I have been following the course of a strain of Equine Influenza in India. It has been traveling from the high mountains of Kashmir down through the western side of the country. Recently, the racetracks in Mumbai were closed.

The disease was hitting working horses and racing horses and polo ponies. It has shut down racing in the country just as it did in Australia last year. But because it is India, we are not hearing so much about it.

When I heard that it had hit the carriage horses that are lined up outside the Taj Mahal in Mumbai, I thought of this photo, one of my favorite images by the great globetrotting farrier Bernard Duvernay of Geneva, Switzerland, aka "The Flying Anvil". He is also a superb photographer whose photos show that he cares as much for people as he does for horses' feet.

His fascination and affection for India are contagious.

Click here to read an interview with Bernard Duvernay about the state of farriery in India for the burgeoning Thoroughbred breeding and racing industry. (Remember that English is not Bernard's native language.)

I hunted down this image from my files and had it ready to go. Then I heard the news on Wednesday that the area around the Taj Mahal and other sites in the great teeming city had been attacked. I wondered if I should publish this photo or not.

The lastest count is 125 people dead and more than 300 wounded.

I can't imagine how the police have handled this situation. Mumbai is probably the largest single city on earth. More people life in that one city than on the entire continent of Australia. The streets aren't just crowded, they are full.

I know a lot of veterinarians and farriers who have gone to Mumbai and the outlying stud farms or to Pune to work on valuable horses with quarter cracks or laminitis. Bernard is the one who goes there to teach the local farriers and to help upgrade their skills. He convinces the stud owners that their future lies in the farriers they have, not in the farriers who come through the airport.

How ironic that Danny Coyle's great (I hear) new film "Slumdog Millionaire" has just opened. It is about Mumbai. The old Mumbai. The one before this happened. I was going to see it this weekend. Mumbai in technicolor. Mumbai in action. People told me that the city was the star of the movie.

Until a week ago I couldn't have found Mumbai on a map. I didn't know if it was on the coast (or which coast) and I probably wasn't sure how to spell it. Now I can't get it off my mind.
