The pressure of the
wall at the toe upon the exudate between wall and coffin bone,
tends to force the coffin bone and sole out of their normal
position. Leave the sole alone. You can lower the excess of growth
at the heels.

"There are many designs of shoes to relieve this condition. A great
deal depends on the judgment of the shoer to meet the conditions
presented, depending on the degree of the convexity and strength of
the sole. In some cases we use a shoe that admits of a large amount
of sole room. Again, we shoe with a shoe of wide cover. In other
cases a shoe with even pressure over the whole sole. In some cases
a high, narrow shoe, resting only on the wall, or the ordinary
plain shoe with side calks welded close to the outside edge and the
shoe dished well from these as a foundation. Then we have the air
cushion pad designed after the model of the bowl shoe."

In cases when slight and persistent lameness interferes sufficiently to
prevent using an animal at any sort of work on hard roads, median
neurectomy will relieve all lameness in most instances. This is a safe
operation, moreover, in that no bad after effects are to be feared, even
though lameness were to continue.

Calk Wounds. (Paronychia.)

Etiology and Occurrence.--Injuries of various kinds are inflicted upon
the coronary region but usually they are due to the foot being trampled
upon. When the foot that inflicts the injury happens to be unshod, a
contusion of the injured member is occasioned, but in the majority of
instances, wounds that demand attention are the result of shoe calks
which have penetrated the tissues in the region of the coronary band.
Often calk wounds are self-inflicted. When animals are excited and in
turning crowd one another, they often perform dancing movements which
frequently result in deep calk wounds of the coronet. Some horses have a
habit of resting the heel of one hind foot upon the anterior coronary
region of the other. While sleeping in this position, if they are
suddenly awakened, the weight is abruptly shifted to the uppermost foot
and the one underneath is (because of the pain attending its being
wounded) quickly drawn out from under its fellow. In this way deep cuts
may divide the coronary band and inflict extensive injury to the
sensitive lamina as well.

An infectious type of coronary inflammation occurs in some localities
