Many people have heard of “nerving” a horse for navicular disease, as was mentioned in the Step-by-Step column in the August issue of The Horse.

Madison said there are several methods of severing the nerves, with no research that shows one technique better than the other. He prefers the capping technique, considered a temporary procedure, which involves cutting the nerves with a sharp knife and then capping the ends of the nerves by taking the epineurium (tissue around the outside of the nerve) and making a cap over the end of the nerve
