Navicular Syndrome: What Horse Owners Should Know

What is it?
Navicular syndrome is a common cause of long-term (usually front) foot pain in horses. It affects the structures in the back half of the hoof, including the navicular bone, deep digital flexor tendon, navicular bursa, collateral sesamoidean ligament, and collateral sesamoidean impar ligament).

Who gets it?
It's most often seen in adult horses, especially those used for heavy work or certain breeds like Quarter Horses, Thoroughbreds, and Warmbloods. Horses with very steep or very low hoof angles are also more at risk.

What are the signs?
• Lameness, usually in the front feet
• Horse may land toe-first instead of heel-first
• Lameness often gets worse when turning in circles
• Both front feet may be affected

What causes it?
• Repeated stress and strain on the navicular area
• Wear and tear on the bone and soft tissues
• Sometimes, poor hoof shape or conformation

How is it diagnosed?
Veterinarians use nerve blocks, radiographs, ultrasounds, and MRIs to pinpoint the source of pain.

How can it be managed?
Management options include special shoeing, rest, and medications. The right approach depends on the individual horse and the specific problem. Remember, what might help one horse might not help another. Overall, early diagnosis and tailored care can help many horses stay comfortable and active.

If you have questions or concerns about navicular syndrome in regard to your own equine, contact your veterinarian.
