Navicular Syndrome simply refers to changes deep with in the hoof and
involves the navicular bone. Previously described as a disease, navicular
is now thought to be a preventable disorder. Navicular syndrome is
responsible for intermittent front leg
lameness in horses. The syndrome is thought to be directly caused
by over exertion of the foot. Hard stops, abrupt turns at high speed, and
percussion on over extended fetlocks, seem to be at the root of navicular
syndrome. This pretty well describes what is required of our horses in
many disciplines, both Western and English Competition.
The healthy navicular bone has the amazing ability to increase it’s density according to the stresses demanded upon it. But recent research suggest that it is the damage to the surrounding tissue, ligaments and infra-structure of the hoof caused by the stresses of training and Competition that sets the equine athlete up for problems involving the navicular. The swelling and resultant internal pressure compromises circulation to the area. The fluid trapped fluid and blood results in depleted oxygenation and a myriad of tiny blood vessels die, further decreasing the navicular’s ability to regenerate.
The syndrome is not reversible, but may be preventable if we can protect
the invaluable blood supply and provide proper support for the lower leg
and fetlock joint. Magnetic pads under shoes or in an easy boot along
with wraps on the lower leg should increase blood flow to this area.
Helping not only the underlying Navicular bone but improving hoof integrity
as well.
