Horse Navicular Disease: Welfare and Modern Management

Navicular disease (podotrochleosis) causes chronic forelimb lameness in horses. Modern understanding and management options offer better welfare outcomes than older approaches.

Key Facts

Navicular disease involves pathology of the navicular bone, deep digital flexor tendon, and associated bursa
It affects primarily Warmbloods, Quarter Horses, and Thoroughbreds, causing insidious onset forelimb lameness
Conformation (upright pasterns, small feet) and workload are predisposing factors
Diagnosis is by nerve blocks, radiography, and MRI for detailed soft tissue assessment
Treatment options include corrective shoeing, anti-inflammatory medication, bisphosphonates, and surgery
Palmar digital neurectomy (nerve cutting) is a last resort that carries ethical and safety concerns

Welfare Considerations

Navicular disease causes chronic pain that significantly reduces quality of life — affected horses show reluctance to work, stumbling, toe-pointing at rest, and behavioral changes reflecting persistent discomfort. Early intervention with appropriate farriery (egg bar shoes, raised heels), combined with NSAIDs and where appropriate bisphosphonate therapy (tiludronate), can significantly reduce pain and maintain workable levels of comfort. Horses managed humanely for navicular disease can have good quality of life, particularly when workload is adjusted to match their capacity.

What You Can Do

Work with both your vet and a skilled farrier to create an integrated lameness management plan
Consider MRI evaluation for accurate diagnosis of which structures are involved before committing to treatment
Adjust workload and ridden exercise to match the horse's level of comfort on any given day
Discuss bisphosphonate therapy with your vet if shoeing and NSAIDs provide insufficient relief
