Navicular Disease in Horses: Chronic Foot Pain and Modern Management

Navicular syndrome causes chronic, progressive forelimb lameness in horses. Understanding the condition and modern treatment options improves welfare outcomes.

Key Facts

Navicular syndrome encompasses several conditions affecting the navicular bone, bursa, and associated structures
It is one of the most common causes of chronic forelimb lameness in horses, particularly in warmbloods and quarter horses
Classic signs include intermittent lameness, toe-pointing when resting, and shortened stride
The condition is often bilateral (both forelimbs affected), making diagnosis more difficult
Modern MRI imaging has revealed that many horses diagnosed with navicular actually have soft tissue injuries rather than bone changes
Management includes corrective shoeing, medical therapy (bisphosphonates, corticosteroids), and in some cases surgical neurectomy

Welfare Considerations

Navicular syndrome causes chronic, daily pain that progressively worsens without management. Horses adapt their movement to minimize weight on painful feet, but this compensation creates secondary pain in other structures. MRI diagnosis has revolutionized treatment specificity — many horses previously labeled as "navicular" have soft tissue injuries that respond far better to targeted therapies than traditional navicular treatments. Corrective shoeing to improve breakover, appropriate exercise management, and medical therapy can maintain quality of life in many affected horses for years. Neurectomy (cutting the palmar digital nerve) eliminates pain but requires careful ongoing hoof monitoring to prevent undetected injury.

What You Can Do

Seek MRI evaluation for horses with chronic forelimb lameness to accurately identify the cause
Work with a farrier and veterinarian together on corrective shoeing for navicular horses
Maintain appropriate body weight in horses — excess weight significantly increases navicular stress
Provide consistent, appropriate exercise rather than periods of complete rest alternating with intense work
