Navicular disease, a common cause of chronic forelimb lameness in horses, is primarily a degenerative condition affecting the navicular bone and its surrounding structures. While it is not typically caused by a single injury, repetitive stress or trauma can contribute to its development over time.
What is Navicular Disease in Horses?
Navicular disease is a complex condition involving the navicular bone, the deep digital flexor tendon, and associated ligaments in a horse’s hoof. It often leads to chronic lameness and can significantly impact a horse’s performance and quality of life. The disease is most prevalent in middle-aged horses and is often seen in breeds used for riding, such as Quarter Horses, Thoroughbreds, and Warmbloods.
Can Navicular Disease Be Caused by an Injury?
While navicular disease is not typically caused by a single injury, repetitive stress or trauma can exacerbate the condition. Factors such as poor hoof conformation, improper shoeing, and excessive workload can lead to increased pressure on the navicular bone and its supporting structures, accelerating degeneration. Therefore, while an injury might not directly cause navicular disease, it can contribute to its progression in horses already predisposed to the condition.
What Are the Symptoms of Navicular Disease?
Recognizing the symptoms of navicular disease early can help manage the condition more effectively. Common symptoms include:
- Intermittent lameness: Often worse after exercise or on hard surfaces.
- Shortened stride: The horse may appear to "tiptoe" or walk on its toes.
- Stumbling or tripping: Particularly on uneven ground.
- Pain in the heel area: Sensitivity during hoof testing.
How is Navicular Disease Diagnosed?
Diagnosing navicular disease involves a combination of clinical examination and imaging techniques:
- Lameness examination: Evaluating the horse’s gait on different surfaces.
- Hoof testers: Applying pressure to identify pain in the heel area.
- Radiographs (X-rays): Assessing changes in the navicular bone.
- MRI: Providing detailed images of the soft tissue structures around the navicular bone.
What Are the Treatment Options for Navicular Disease?
Several treatment options are available to manage navicular disease, focusing on reducing pain and slowing disease progression:
- Corrective shoeing: Balancing the hoof and reducing pressure on the navicular bone.
- Anti-inflammatory medications: Alleviating pain and inflammation.
- Physical therapy: Improving circulation and reducing stiffness.
- Surgical options: In severe cases, procedures like a neurectomy (cutting nerves to relieve pain) may be considered.
How Can Navicular Disease Be Prevented?
Preventing navicular disease involves maintaining good hoof health and managing workload:
- Regular farrier care: Ensuring proper hoof balance and alignment.
- Appropriate workload: Avoiding excessive stress and providing adequate rest.
- Proper nutrition: Supporting bone and joint health with a balanced diet.

What is the Prognosis for Horses with Navicular Disease?
The prognosis for horses with navicular disease varies depending on the severity and response to treatment. With appropriate management, many horses can continue to lead active lives, although they may require adjustments to their workload and care routine.
Can Navicular Disease Be Cured?
Navicular disease is a chronic condition that cannot be completely cured. However, with effective management strategies, the symptoms can be controlled, and the horse’s comfort and performance can be improved.
How Long Does It Take for a Horse to Recover from Navicular Disease?
Recovery time depends on the severity of the disease and the treatment approach. While some horses may show improvement within weeks, others may require months of consistent management to see significant changes.
Are Certain Breeds More Prone to Navicular Disease?
Yes, certain breeds are more predisposed to navicular disease, particularly those used for riding and performance, such as Quarter Horses, Thoroughbreds, and Warmbloods. These breeds often have conformational traits that can increase the risk of developing the condition.
What Role Does Conformation Play in Navicular Disease?
Conformation plays a significant role in the development of navicular disease. Horses with upright pasterns, small hooves, or a long toe-low heel conformation are at increased risk due to the additional stress these traits place on the navicular bone and its structures.
Conclusion
Understanding navicular disease is crucial for horse owners and caretakers. While it is not directly caused by an injury, repetitive stress and poor management can contribute to its progression. By recognizing symptoms early and implementing effective treatment and prevention strategies, the impact of navicular disease can be minimized, allowing horses to maintain a good quality of life.
