Horse Navicular Disease and Palmar Foot Pain

Navicular disease is a major cause of chronic forelimb lameness in horses, requiring careful management to maintain quality of life.

Key Facts

Navicular syndrome affects the navicular bone, associated ligaments, and deep digital flexor tendon
Quarter horses and warmbloods are overrepresented, suggesting a genetic component
Poor hoof balance, inappropriate shoeing, and concussion on hard surfaces are key risk factors
Diagnosis requires nerve blocks, radiography, and often MRI for accurate lesion identification
Treatment includes corrective shoeing, anti-inflammatories, bisphosphonates, and occasionally surgery
Many horses can be maintained in light work with appropriate management

Welfare Considerations

Navicular disease causes persistent, often bilateral forelimb pain that horses struggle to communicate clearly. Subtle signs like toe-pointing at rest, short choppy stride, and reluctance to work on circles are easy to dismiss or misinterpret. Chronic unmanaged pain leads to significant welfare compromise, behavioral changes, and muscle wastage. Advances in MRI diagnosis now allow more targeted treatment of the specific structures affected. With appropriate farriery, pain management, and workload adjustment, many horses achieve acceptable comfort levels - but owner education about early recognition is critical.

What You Can Do

Have any horse showing shortened stride or reluctance on circles promptly evaluated
Work with a skilled farrier and veterinarian to develop an appropriate trimming and shoeing plan
Avoid working navicular horses on hard or uneven ground excessively
Discuss bisphosphonate therapy (tiludronate/clodronate) with your veterinarian
Monitor pain levels regularly using validated equine pain scales
Consider MRI for accurate diagnosis of specific structures involved
