What To Know Regarding Navicular Syndrome
There are certain kinds of diseases that affect horses while remain unknown in donkeys and ponies. One such example is the navicular syndrome. This condition is a major cause of chronic forelimb lameness in horses, especially those used for athletic purposes. The condition is degenerative and involves loss of medullary architecture, bone sclerosis, traumatic, fibrillation, and enthesiophyte formation. The disease was discovered long ago and continues to be a problem to date.
The syndrome results from complex pathogenesis rather than a particular disease entity. However, researchers link biochemical and vascular components to it. Additionally, there is a belief that the disease could be hereditary following the decrease in cases after stallions with the conditions were disallowed certification for breeding. The condition seems to be characteristic in mature horses because it does not appear until the animal is 8 to 10 years old.
The process of disease and the degree of lameness are influenced by how the distal limb is conformed. Excess pressure on the hoof-pastern, under run heels, and long toes are among the key causes of this illness in horses. Excess pressure is placed on the flexor tendons and the navicular bones when the aforementioned factors occur. Additionally, those factors also cause the navicular bursitis and the fibrocartilage to be damaged.
The disease entails several stages, with the final ones getting much worse. Seasonal lameness can be observed during the first phases, but no head nod can be seen because of the bilateral nature of this illness. Moving the animal in circular motion worsens the situation and makes symptoms more visible. Shortened strides are also another characteristic symptom observable during the initial stages.
Diagnosis is based on various factors including breed and age of an animal. Lameness examination reveals a characteristic response from the animal to palmar digital nerve anesthesia. Hoof testers never give positive results as seen in only 11% positives in some studies. The most effective and specific diagnostic procedure is the anesthesia of navicular bursa. However the process is painful and the administering the injection is a complex process.
In cases where the condition has gotten worse, achieving total cure is not possible because the disease is chronic and degenerative in nature. However, the problem can be managed quite well in some cases. Administration of NSAID and utilization of corrective shoes are some of the commonest treatment options used. Phenylbutazone is more commonly used over other NSAIDs. However, GI and renal injury are some of side effects of phenylbutazone, and should be used cautiously.
The efficiency of drugs is also limited and in cases where lameness is severe, rest is the most recommended idea. Besides drugs, measures of foot care are also helpful. The hooves could be trimmed and shoed to restore the normal balance and alignment of phalangeal. The efficiency of the shoes can be determined after two weeks.
One should seek help immediately the condition is discovered. Severe cases can completely disable the animal. There is a lot of pain associated with the disorder and that should always be taken into account.
