s necessary in properly padding the member with
cotton lest sloughing from pressure occurs at the coronet; but this does
not apply in rupture of extensors so much as where flexors are ruptured.

Open wounds are treated along general surgical lines, dressed as
frequently as occasion demands, and recovery will be complete in a few
months' time unless much of the tendon has been destroyed. In one
instance, the author had occasion to observe such a condition, which,
because of the extensive destruction of tendon and lack of facilities
for giving proper attention to the subject, results were so unfavorable
that it was deemed necessary to destroy the animal.

Wounds From Interfering.

When, during locomotion, injury is inflicted upon the mesial side of an
extremity by the swinging foot of the other member, the condition is
termed interfering.

Etiology and Occurrence.--Faulty conformation, bad shoeing and
over-work are the principal causes of interfering. Horses that are "base
narrow" or that have crooked legs are quite apt to interfere. Shoes that
are put on a foot that is not level or applied in a twisted position, or
shoes wide at the heel will often cause interfering and injury. Animals
that are driven at fast work until they become nearly exhausted may be
expected to interfere. Such cases are frequently observed in young
horses that are driven over rough roads, particularly when so nearly
exhausted or weakened from disease or inanition that the feet are
dragged forward rather than picked up and advanced in the normal manner.

Symptomatology.--Wounds inflicted by striking the extremities in this
manner present various appearances and occasion dissimilar
manifestations. The hind legs are almost as frequently affected as the
front and the fetlock region is most often injured, though wounds may be
inflicted to the coronet. In front, the carpus is sometimes the site of
injury.

When only an abrasion is caused, little if any lameness occurs, but
where interfering is continued and nerves are involved or subfascial
infection and extensive inflammation succeed such abrasions, marked
lameness and evidence of great pain are manifested. Frequently, in
chronic cases affecting the hind leg, the fetlock assumes large
proportions, and at times during the course of every drive the subject
strikes the inflamed part, immediately flexing and abducting the injured
member, and the victim hops on the other leg until pain has somewhat
