Basics Of Navicular Syndrome In Horses

By Lena Stephenson


Caudal heel pain syndrome refers to a degenerative disorder of the structure of hoof of a horse. Navicular syndrome is particularly associated with the navicular bone, which is sometimes known as distal sesamoid bone. Distal sesamoid bone is small and is set deeply within the hoof. It is as the posterior junction of the short pastern and coffin bones.

The disease is characterized with a lot of pain due to changes in the position of bursa, ligaments, tendons and bones. Partial lameness, which worsens with time, is observed among animals suffering from the disorder. The pain is experienced in the fore feet making the horse want to reduce strain placed on them as much as they can. While resting, the most painful hoof is normally held ahead of the other.

The other indicators of the disorder include a horse having difficulties in turning sharply. It also becomes hard for the affected animal to move on hard or rocky ground as well as finding it hard to go downhill. The disorder makes a horse very uncooperative during shoeing or trimming as they involve picking up one front foot leaving the other to support the animal. Once, the weight is concentrated on one foot the horse feels unbearable pain thus the stubbornness.

The disorder can affect any type of horse as there is no guarantee that certain breeds do not get affected. Even though, the disease is common in stock type horses like quarter, appaloosas, and paints horses. The condition is worse in thoroughbreds and warmblood horses. On contrary, Arabian breeds hardly suffer from the disorder. Body weight contributes to caudal heel pain as an overweight animal exerts too much pressure exerted on the musculoskeletal system.

The pain increases with work and decreases with more resting time. Affected horses should be treated once the disorder is ascertained by a qualified veterinary. Treatment may be inform of alterations in schedule or operation. Trimming the toes and shoeing with square shaped shoes may go a long way in helping the horse.by doing so the strain placed on the hoof is greatly reduced.

Medical treatment includes administration of anti-inflammatory drugs like phenylbutazone. Vasodilator drugs such as pentoxifyline, metrenperone, and isoxsuprine are used to increase blood flow to the affected areas. Application of some drugs is not allowed if the horse is to take part in certain competitions. For this reason, it is good to consult with a certified veterinary before administering any drug.

Surgical approach to navicular disease involves digital neurectomy. Neurectomy involves transecting the digital nerve within the lower pastern area and prolonging its growth as long as possible. The surgery can be performed using two approaches. The first approach includes transecting the nerve using a scalpel blade or performing the surgery using high-tech operation laser. Either approach is used when deemed necessary and also to minimize complications.

Neurectomy is not cure rather it is a technique that removes the pain when every method has failed. It is not a long-lasting solution as it might have to be repeated at some time. Compilations can arise from this technique though this is rear. Neuroma is the commonest complication.it is a painful tumor, which grows at the tip of transected nerve.
