Navicular disease in horses is a chronic condition affecting the navicular bone and its surrounding structures in the hoof. Effective treatment options aim to alleviate pain and improve mobility, ensuring a better quality of life for the horse.
What Is Navicular Disease in Horses?
Navicular disease is a degenerative condition that primarily affects the navicular bone and the associated soft tissues, such as the deep digital flexor tendon and the navicular bursa. It typically causes lameness in the front feet, leading to discomfort and reduced performance.
Symptoms of Navicular Disease
- Intermittent lameness, often in one or both front feet
- Short, choppy stride
- Reluctance to turn sharply or work on hard surfaces
- Sensitivity to hoof testers applied over the heel area
How Is Navicular Disease Diagnosed?
Diagnosing navicular disease involves a combination of clinical examination, radiography, and sometimes advanced imaging techniques like MRI. Veterinarians look for signs of pain, changes in the hoof structure, and abnormalities in the navicular bone.
What Treatments Are Available for Navicular Disease in Horses?
1. Corrective Shoeing and Trimming
Corrective shoeing is often the first line of treatment for navicular disease. It aims to reduce pressure on the navicular bone and improve hoof balance. Farriers may use:
- Egg bar shoes: Provide extra support to the heel
- Rocker shoes: Encourage a natural breakover point
- Wedge pads: Elevate the heel to reduce tendon stress
2. Medication
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to manage pain and inflammation. Corticosteroid injections into the navicular bursa can also provide relief. Long-term use, however, should be monitored due to potential side effects.
3. Exercise and Physical Therapy
Controlled exercise can improve circulation and strengthen the structures within the hoof. Physical therapy may include:
- Hand walking: Encourages movement without excessive strain
- Swimming: Provides low-impact exercise
- Stretching exercises: Enhance flexibility and reduce stiffness
4. Alternative Therapies
Some horse owners explore alternative treatments to complement traditional methods. These may include:
- Acupuncture: May help alleviate pain and improve circulation
- Chiropractic care: Aims to improve overall musculoskeletal health
- Nutritional supplements: Support joint and hoof health
5. Surgical Options
In severe cases, surgical intervention may be necessary. Options include:
- Palmar digital neurectomy: Severing the nerve to relieve pain, though it carries risks
- Bursoscopy: Minimally invasive surgery to clean the navicular bursa
How to Prevent Navicular Disease
Preventing navicular disease involves proper hoof care and management practices:
- Regular hoof trimming and shoeing
- Avoiding excessive work on hard surfaces
- Maintaining a healthy weight and balanced diet
People Also Ask
What Are the Long-Term Effects of Navicular Disease in Horses?
Navicular disease can lead to chronic lameness and reduced performance. With proper management, many horses can continue to be active, though they may require ongoing treatment and adjustments to their workload.
Can Navicular Disease Be Cured?
While there is no cure for navicular disease, effective management can significantly improve a horse’s quality of life. Treatment focuses on alleviating symptoms and slowing disease progression.
How Does Diet Affect Navicular Disease?
A balanced diet supports overall hoof health. Omega-3 fatty acids, biotin, and other joint supplements can be beneficial. Avoiding excess weight helps reduce strain on the hooves.
Are There Any New Treatments for Navicular Disease?
Research is ongoing, with regenerative medicine showing promise. Treatments like stem cell therapy and platelet-rich plasma aim to repair damaged tissues and improve outcomes.
How Do I Know If My Horse Has Navicular Disease?
Consult a veterinarian if your horse shows signs of lameness or discomfort, especially in the front feet. Early diagnosis and intervention can improve treatment success.
Conclusion
Navicular disease in horses requires a comprehensive approach to management, combining corrective shoeing, medication, and alternative therapies. By understanding the symptoms and treatment options, horse owners can work with veterinarians to ensure their horses lead comfortable, active lives.
