How to diagnose navicular disease in horses?
Diagnosis is based on a combination of history, symptoms, nerve blocks and radiography. A history of intermittent low grade or recurrent lameness is suggestive of navicular disease. Affected horses often appear to place the toe down first, as if trying not to put weight on their heels (in contrast to laminitis), and the lameness is worse on the inside leg on a circle. Injection of local anesthetic (nerve block) around the nerves sensitizing the back half of the foot and/or into the navicular bursa will improve or alleviate the lameness associated with navicular disease. Some cases also improve when the coffin joint (P2/P3, distal phalangeal or DIP joint) is blocked. Radiographs (x-ray pictures) may reveal damage to the navicular bone but bone changes can be difficult to interpret, as there are differing opinions on what is 'normal'. Navicular syndrome can exist without demonstrable radiographic abnormality and magnetic resonance imagining (MRI) may reveal injury to the impar or other ligaments or soft tissues.
What causes navicular disease?
