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 condition never results from a disease entity rather from complex pathogenesis. However, biochemical and vascular components have been linked to it by researcher in that field of study. Additionally, heredity has been added to causes because after disallowing affected stallions from breeding, cases seemed to degrease in number. The appearance of the disease in horses that are 8 to 10 years in age makes it characteristic in mature horses.
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 occurs in stages with later stages getting worse and severe. When the disease is still in its early stages, there is intermittent lameness and owing to its bilateral nature, there may never be any visible head nod. This is especially when moving the animal on a straight line. One of the mild signs at this stage is a shortened stride. During early stages, the condition could be worsened when the horse is moved in circles.
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.
The nature of the disease is that it is degenerative and chronic, making achievement of total cure impossible, especially in severe cases. However, in some cases, the condition has always been managed very well. Corrective shoeing and administration of NSAID are among the commonest options for treatment. Phenylbutazone is the most commonly utilized NSAID. However, renal injury and injury are common side effects that could result from using phenylbutazone and as such should be utilized 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.
It is recommendable to seek assistance immediately the condition is discovered. Animals can be disabled by severe cases. Animals feel a lot of pain if not treated in time.
