liability with increasing strength and age. This dislocation may be
partial or complete. In the former instance and the most common is where
the patella, or the little stifle bone that glides in the groove
composed of the lower hip and upper thigh bones, has become partially
dislocated or removed from its natural position.

SYMPTOMS: When the dislocation is complete the affected limb is drawn
forward, while the foot from the pastern down is drawn backward, and the
animal may throw weight on it when made to move, which is accomplished
with great difficulty. When the dislocation is partial, the symptoms are
about the same as mentioned, only the limb is less rigid. If the horse
is moved, the stifle makes a klick sound. In this form, you may have
both limbs affected.

TREATMENT: In partial dislocation, the stifle bone may be replaced by
drawing the leg forward, and with the hand pressing in on the stifle. In
complete dislocation, tie a rope around the pastern of the affected leg,
then draw the rope through a collar placed around the horse's neck and
draw forward as far as possible and tie. Then press with both hands
inward. After the stifle is placed back into position use the following
liniment: Aqua Ammonia Fort., four ounces; Oil of Turpentine, four
ounces; Raw Linseed Oil, four ounces. Mix and apply well over the stifle
joint once or twice a day for two or three days. Feed nourishing food
and put the animal to slow, easy work or turn out to good pasture.

In old chronic cases of Stifle Joint Lameness, treatment is of no value,
therefore, care for the animal as soon as the catch in the walk or
lameness appears.

STRING-HALT

CAUSE: Several theories have been put forth as to the cause of
String-Halt which is generally supposed to be a nervous disease; a
condition opposite to paralysis. The exact cause of this disease is hard
to determine, but it is likely to occur in highly nervous horses. It
sometimes follows an injury which may have irritated the nerves in some
way. I believe that castration causes it in many instances, due to the
severe struggle when being thrown, or pulling down severely on the
spermatic cord when removing the testicle.

SYMPTOMS: Spasmodic contraction of one or both limbs. This sign varies,
as sometimes it is very violent, while in others it may be so slight
that it is hard to detect when stepping the horse forward, but on
backing or turning the horse around the signs are easily noticed.
