Horse Navicular Disease: Emerging Therapies and Welfare

Navicular syndrome is a common cause of forelimb lameness in horses, and evolving understanding is improving both treatment options and welfare outcomes.

Key Facts

Navicular syndrome involves degeneration of the navicular bone, bursa, and associated soft tissues
Quarter Horses, Thoroughbreds, and Warmbloods with upright hooves are most commonly affected
Corrective shoeing remains a cornerstone of management, optimizing hoof balance and breakover
Bisphosphonate medications (tiludronate, clodronate) can slow bone resorption and reduce pain
Extracorporeal shock wave therapy provides pain relief in some horses without resorption inhibition
Advanced imaging (MRI) allows precise diagnosis of which structures are affected, guiding targeted treatment

Welfare Considerations

Navicular syndrome causes chronic, often progressive pain that significantly impacts horse welfare and working capacity. The historical approach of masking pain with nerve blocks to keep horses in work without treating the underlying cause is now recognized as ethically problematic. A horse that is numb to pain in its foot will continue to damage structures it cannot feel, worsening long-term prognosis. Welfare-centered management prioritizes pain relief, hoof health, and honest assessment of whether continued work is appropriate.

What You Can Do

Seek specialist lameness evaluation including imaging if your horse shows forelimb lameness or shortened stride
Work with an experienced farrier and veterinarian together to optimize hoof care for navicular horses
Ask your vet about bisphosphonate therapy if the diagnosis involves active bone resorption
Provide deep, soft bedding and turnout on appropriate surfaces to reduce concussion on affected feet
Consider retirement or reduced workload honestly rather than masking pain to continue performance
Maintain healthy body weight to reduce loading on affected feet
