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 progresses through stages and the latter stages are normally worse. During early phases of disease, intermittent lameness is observable, but there is no observable head nod because the disease is normally bilateral in nature. Intermittent lameness becomes more visible when moving the animal in circles. Another additional symptom one can observe at this stage is shortened strides. Circular motion can make the situation worse for the animal.
Age and breed of an animal are some of the factors based on when making a diagnosis. Performing a lameness examination should show a characteristic to palmar digital nerve anesthesia by the animal. Some studies only revealed 11% of positive results from hoof testers, making the test to be regarded as not sufficient in all cases. Anesthesia of navicular bursa seems to be the most effective and precise diagnosis process. However, owing to the amount of pain involved and the complexity of the injection, this process is not performed during lameness examination.
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.
In cases where the lameness is much worse, efficiency of drugs could be limited, leaving rest as the only recommendable treatment. Incorporating foot care measures can also work well together with drugs. The alignment and balance of phalangeal could be restored by trimming and shoeing the hooves. A period of two weeks is enough to determine if the shoeing is effective.
Seeking medical assistance the minute the problem is discovered is advisable. Total disability could result if one delays. Animals that are not treated on time undergo a lot of pain.
