r
lateral cartilage was gangrenous, as was also a small spot on the
extensor tendon near its point of attachment on the coffin bone. Several
small collections of pus were found deep in the connective tissue of the
coronary region; along the course of the sesamoid ligaments; in the
sheath of the flexor tendons; under the tendon just below the fetlock
joint in front; and in the coffin joint.

But all cases of tendinous quittor are by no means so complicated as
this one was. In rare instances the swelling is slight, and after a few
days the lameness and other symptoms subside, without any discharge of
pus from an external opening. In most cases, however, from one to half a
dozen or more soft points arise on the skin of the coronet, open, and
discharge slowly a thick, yellow, fetid, and bloody matter. In other
cases the suppurative process is largely confined to the sensitive
laminae and plantar cushion, when the suffering is intense until the pus
finds an avenue of escape by separating the hoof from the coronary
band, at or near the heels, without causing a loss of the whole horny
box. When the flexor tendon is involved deep in the foot, the discharge
of pus usually takes place from an opening in the follow of the heel; if
the sesamoid ligament or the sheath of the flexors are affected, the
opening is nearer the fetlock joint, although in most of these cases the
suppuration spreads along the course of the tendons until the navicular
joint is involved, and extensive sloughing of the deeper parts follows.

_Treatment._--The treatment of tendinous quittor is to be directed
toward the saving of the foot. First of all an effort must be made to
prevent suppuration; if the patient is seen at the beginning, cold
irrigation, recommended in the treatment for cutaneous quittor, is to be
resorted to. Later, when the tumor is forming on the coronet, the knife
must be used, and a free and deep incision made into the swelling.
Whenever openings appear, from which pus escapes, they should be
carefully probed; in all instances these fistulous tracts lead down to
dead tissue which nature is trying to remove by the process of
sloughing. If a counter opening can be made, which will enable a more
ready escape of the pus, it should be done at once; for instance, if the
probe shows that the discharge originates from the bottom of the foot,
the sole must be pared through over the seat of trouble. Whenever
suppuration has commenced the process is
