Navicular disease

Navicular disease is a degenerative condition affecting the navicular bone, a small bone located within the hoof of a horse. This disease is one of the most common causes of lameness in horses, particularly in the front limbs.

Causes

The exact cause of navicular disease is unknown, but it is believed to be multifactorial. Factors that may contribute to the development of the disease include genetics, conformation of the horse, and the type of work the horse is used for.

Symptoms

The primary symptom of navicular disease is lameness, which may be subtle and intermittent in the early stages of the disease. As the disease progresses, the lameness may become more severe and constant. Other symptoms may include a shortened stride, reluctance to move, and changes in behavior due to pain.

Diagnosis

Diagnosis of navicular disease is based on clinical signs, a thorough veterinary examination, and imaging studies such as radiography, ultrasound, and magnetic resonance imaging (MRI).

Treatment

Treatment for navicular disease is aimed at managing pain and slowing the progression of the disease. This may include rest, changes in shoeing, medication, and in some cases, surgery.

Prognosis

The prognosis for horses with navicular disease varies depending on the severity of the disease and the response to treatment. With appropriate management, many horses can continue to have a good quality of life.
