One of the best things about the Hoof Blog is hearing from people inspired to share how they would use different materials or methods to achieve the same thing.
Paul Raw, DipWCF is a farrier in northern England who had never heard of the California Wrap featured on the Hoof Blog back in December 2012. But as soon as he saw what Southern California Equine Podiatry's Dr Mark Silverman and farrier Ernest Woodward had done for a case of white line disease, Paul "got it" -- because he had come up with a similar solution using a completely different material.

In both cases, the problem is white line disease in the lateral wall but there's a very big difference between the two cases that goes far beyond the variation in materials. In California, the assignment was simply to create a treatment-friendly matrix that would allow someone else to shoe the horse. Ernest never drove a nail into his adhesive-impregnated fabric hoof jacket. But someone else did. (Photo below.)
Paul, on the other hand, built his design from the shoe up. His choice for a shoe was a glue-on Imprint thermoplastic shoe. For those who haven't seen them, these shoes are extremely lightweight and, when heated, become completely malleable.
To help Reggie, a Thoroughbred gelding with white line disease, Paul's vet-reviewed wall jacket includes the negative space of a palladium-style treatment window. He constructed the jacket of moldable thermoplastic granules, which are integrated into the shoe made of the same material. The granules are transformed by hot water or a heat gun into a flexible, shapable, transparent material that can fill cracks, create extensions, or (in this case) create a barrier jacket over the hoof.
|After six weeks in the thermoplastic wrap, the foot had recovered enough that Paul reversed the process he had begun: he filled the defect with thermoplastic crystals and shod the horse with a Blurton heart bar shoe.|
The Hoof Blog asked Paul if brittleness was a factor in the Imprint system. He answered, "They do not get brittle at all as (the material) has been engineered to mimic the exact hardness of the equine hoof so it is very flexible."
"It was packed with pevidine (iodine solution) and sugar (known as "sugardine" in the USA) for the first week," Paul continued, "as it acts as a super drying agent but keeps it clean while new tissue granulated. Then it was left open for the air to get to it unless (the horse) was going anywhere unclean-- i.e muddy field or hacking out -- then it was wrapped up with duck (tape) briefly to keep it clean to reduce the chance of it abscessing."
How did Paul's palladium window work on this horse? He reports: "I did see the horse after that and still shoe him. The shoe stayed on for six weeks, which was long enough for the treatment to make such a leap forward I was able to fully fill the crack with Imprint granules on the second shoeing and within 4-5 months it had completely grown out. The horse was back in work after a month."
