Diseases & disorders of the Diseases & disorders of the horse : a treatise on equine medicine and surgery diseasesdisorder00gres Year: 1886 152 CORNS. Corns are bruises or contusions of the sensitive membrane, which covers the lower surface of the coffm-bone, and secretes the horny sole. A corn appears as a small reddish spot or patch, in the space between the bars and thejvall at the heel. Corns are almost always met with in the fore feet, though the hind ones are also sometimes affected. In nearly all cases it is the insides of the feet, which are the seats of these bruises, and this is probably attributable to the fact that more weight is thrown on the inner than on the outer side of the foot. We mentioned, in treating of navicular disease, that the fore feet were much more liable to suffer from continued concussion than the hind ones. This would also account for the much more common occurrence of corns in the fore feet than in the hind ones. As in navicular disease, so in the case of corns, it has been observed that animals subjected to constant work on hard ground, are more liable to become affected ; and this is especially the case with high-stepping animals, with weak heels and marked 'heel action.' In the accompanying picture of the near fore foot, A shows the position of corns between the bar B and the wall at the heel. The chief cause of corns is the irrational method of shoeing, which causes pressure at the seat indicated at A in the above picture. In the opinion of Professor Williams, 'the ordinary seated shoe is the most irrational and insensate one which ever emanated from man's brain. It is a mechanism which bears upon no fart of the sole, except upon the spot which is incapable of pressure. It is dished out, made concave all round the foot
