Understanding The Navicular Disease In Horses: Diagnosis And Management

By Francis Riggs


Whenever a horse is labeled as suffering from the 'navicular', there is a tendency of people to shy away from him, making it look like he was suffering from some deadly malady like the Typhoid Mary or other similar diseases. Many people are in the dark when it comes to treating or even visualizing the navicular disease in horses. This is a condition that the feet that normally results in lameness and is most likely to appear as the lameness in one of the forelimbs.

Unknown to many horse owners, a horse with the said condition can easily be brought back its former perforce level, all that is needed is proper management by someone who fully understand what it take to manage the condition. In order to understand the situation better, compare the horse with an athlete that has been diagnosed with bad feet, the athlete can go back to its former level of performance as long as it is well managed; the same goes for the horse.

The most common sign the vet will normally notice is a history of the front leg lameness which can be gradual. At times, the lameness can be observed on both front feet. The other sign is a history stumbling and developing a choppy gait that appears to be uncomfortable. The condition is also more common with the thoroghbreds and the quarterhorses than other breeds as they are larger in size and rests on small feet. The onset of signs is also common at the age of 7 to 14 although it can occur at any age.

There is no particular cause of the condition as several factors can contribute to the diseases. In the same way, it is rare to find one treatment procedure that is successful. Bute is widely used as it is known to reduce pain as well as inflammation, particularly in the early stages of the syndrome.

Other risk factors include the horse breed. The quarterhorse breed and the thoroghbreds are at higher risk than other horses as their legs are smaller as compared to their big bodies. The signs are more likely to be noticed from the age of 7 to 14.

However, the best option to differentiate the possible causes of foot lameness is the selective nerve blocks, although it is still associated with a few limitations. As such, most experienced veterinarians usually use a combination of radiographs and the nerve blocks techniques.

The other common alternative is the use of corrective shoeing particularly when the condition is chronic. This involves trimming each of the affected shoes to conform to particular needs. The shoe types used include the rolled toe shoe, the wide web shoe, the Tennessee navicular shoe, the slippered hell shoe, and the egg bar shoe among others.

However, the steroids are used particularly when it is suspected that the origin of the pain is from the coffin joint or the navicular bursa. This is far from the cure as it only reduces inflammation but does not cure the underlying pathology problems. The other treatment includes administration of isoxcuprine hydrochloride, use of an anticoagulant, corrective shoeing techniques and neurectomy for chronic cases.
