Navicular
disease as
it is more commonly known must be looked at and
treated as a syndrome rather than a specific item
~ this is due to the fact that many different
parts of the foot could be affected when it is
present.
This
is one of the most common lameness factors
in horses and is seen to happen in the front feet
rather than the rear feet. It also seems to first
effect horses from the age of four and up to nine
years of although it is mainly seen in the front
feet, it can affect the rear feet, but is
extremely rare to find rear feet that are
affected.
Over
the years various theories have come to light
about what causes the navicular syndrome to
begin. It was first thought to be an arthritic
condition that was brought about from either an
injury from excessive pounding or hard usage of
the front feet of the horse. There are also
additional theories that have added in the
research and development of a broader
understanding of this entire condition. What has
been discovered is the fact that certain horses
have traits that allow us to pre-determine, with
some sort of accuracy, the type of horse that may
be more prone to suffer from this condition.
Information now tells us that the horse that has a
history of previous horses in its lineage that
have suffered from navicular syndrome are more
likely to also suffer from navicular syndrome.
This is pre-determined through conformation
faults
that are inherited from their parents and/or
grandparents or in some cases both.
It
has also been proven that improper trimming
and/or
shoeing techniques
can contribute to the progression of the navicular
syndrome at
a faster than normal rate. In reference to horses
that are pre-disposed to the condition through
conformational faults can have the condition
accelerated as well by too hard a work schedule or
even by being worked in improper ground conditions
(to hard a surface). Further findings have found
that an improper diet can also advance the
condition at a faster rate of speed that the
specific animal may experience.
The
front foot that is affected by this condition will
also change its appearance as time goes on and the
condition progresses in severity. The foot will
become “contracted”
at the heels and the frog will
start to shrink in size ~ with the shrinking of
the frog the pressure to it will be reduced and in
some cases total eliminated which leads to the
added condition of “thrush”
in most cases. The foot will appear to become “boxy”
in shape as the condition progresses and will
become smaller than the less affected foot as
well.
Horses
that suffer from navicular disease are
ones that have a history in their lineage of
preceding horses having the same condition. This
is found to be true through conformational traits
that are passed from generation to generation. In
addition, horses that have too small a foot for
the amount of body mass that they have to support
are
also a high risk factor for this condition.
Don’t forget horses that do not get adequate
conditioning for the work that they are asked to
do.
The
best treatment for navicular disease is
through complete and correct farrier techniques
using a shoe that properly supports and protects
the heel area
of the foot with a wide web, all of these factors
allow for the maximum benefit of the program to be
accomplished and the horse to be aided in their
ability to reduce the amount of pain that they are
suffering. Additional care must be taken to make
sure that the toe of the shoe is shaped in a
manner that will allow for the ease of operation
and allow for the maximum roll over to be
accomplished. The program that is established for
the correct and proper maintenance of the horse
suffering from this condition needs to be followed
on a four to six week cycle so that the proper
angle and position of the foot can be realized at
all times, thus allowing the horse to suffer as
little amount of pain as possible on a regular
basis.
With
proper care and treatment most horses can extend
their usefulness by up to five years and in some
cases even longer. This can be accomplished
through a shorter shoeing cycle,
more exercise and a good and balanced diet
that does not allow for over-feeding.
Proper
Treatment for Navicular Problems
In
order to properly have the correct procedures be
followed there has to be quite a few points that
need to be both considered and accomplished. These
points are easy enough to explain and sometime
difficult to accomplish, since the correct
decision and procedures have to be determined and
accomplished that are correct for the particular
situation that your horse is going through.
Additionally, you are at the mercy of persons that
may or may not know what is necessary or even
required to set your horse onto the most
comfortable path to recovery.
There
has to be some very basic points that the farrier
has
to cover within themselves to make sure that they
are able and experienced enough to accomplish what
is necessary to both start and finish the task at
hand. If they do not have the required abilities,
they then have to be professional enough to help
the horse by referring or bringing to your
attention another person that is experienced
enough to accomplish what may be necessary. A
point of contention here is that just because the
average farrier is quite capable of taking care of
the day-to-day requirements of the average or
good-footed horse, it does not mean that they have
the highly skilled ability or the knowledge that
is specifically required to help the horse
correctly. There are people within the farrier
industry that do specialize in what is referred to
as “Corrective” or
“Orthopedic” style
of farrier work. This specialist is what is
required at this point. It would also be a major
point of progression for your particular farrier
to assist the specialist so that knowledge and
expansion of abilities can happen. The results of
this can be two fold, the farrier gains the
knowledge and the experience of the more advanced
education and allows the same farrier the ability
to be available in the event that the specialist
is unable to get to the horse right away in the
event that shoes may be thrown or minor adjustment
might be required to be accomplished when the
specialist is not readily available. Most
specialty farriers have no problem with this
arrangement since they have a great amount of
workload from being a limited number of themselves
to be able to accomplish all of the work that is
out there. Any point that allows them to have a
bit of
the load removed will be greatly appreciated.
The
farrier that
is chosen to accomplish the work that is required
needs not only the experience but the proper
amount of confidence has
to be in place that will allow them to make the
solid judgments that may be necessary as they
appear and have to be dealt with in a positive
way. The person that you have chosen to accomplish
the necessary work must have a positive
relationship with the veterinarian that you have
been working with on this particular problem, for
if you do not look at that point there could be
major conflicts in the procedure to follow as the
program progresses. Once an initial program has
been started it has to be followed and not wavered
from; this takes cooperation on both sides of the
equation to end up with the correct answer that is
right for the horse. The ability to understand the
principles of allowing the horse to be balanced
from
the ground up through the entire body must also be
understood, for understanding the complete balance
principles
there will be a complete understanding of the
interior of the foot and its proper and correct
operation and position.
One
of the most important abilities that a specialist
type farrier can
have is the ability of being able to look at the
problem that is at hand and to visualize within
their own mind the finished product before the
work is even started. This one ability will allow
them to have the finished product always looking
them in the face as they progress through the
various steps and procedures that will lead to the
completion to the program. This is the same as
filing a flight plan by a pilot to make sure that
they follow the safest and most reasonable path
and to get to their required destination in the
required time.
As
the owner of such an animal that has suffered from
this particular foot situation there are also
requirements on your side of the fence. You have
to be able to change ~ you have to remember that
this situation did not occur overnight ~ and
can’t be fixed over night either. The changes
that the owner has to make are that they have to
be able to start to provide the necessary after
care as both the veterinarian and the specialty
farrier direct
you. What they will be doing is instructing you as
to the everyday procedures that are necessary
since this situation can be slowed down, but it
will never go away. The horse can be made more
comfortable, but never totally recover from this
particular problem. The shoeing process
for a navicular problem is best realized that the
overall support of
the leg, the foot and the tendon have
to be changed and the correct foot balance has
to be realized so that the shock and concussion
that
is introduced to the foot with each step is
minimized.
