Horses are magnificent creatures that have been an integral part of human life for centuries. Their strength, agility, and beauty make them a popular choice for various equestrian activities, such as racing, jumping, and trail riding. However, like any living being, horses are prone to various health issues that can affect their performance and overall well-being. One such issue is navicular syndrome, a painful and debilitating condition that affects the navicular bone in the horse’s hoof.
What Causes Navicular in Horses?
Navicular syndrome is a complex condition that is caused by a combination of genetic, environmental, and biomechanical factors. It is characterized by inflammation and degeneration of the navicular bone and surrounding tissues, leading to pain, lameness, and reduced performance in affected horses.
Genetic Factors
Genetic predisposition is believed to play a significant role in the development of navicular syndrome in horses. Certain breeds, such as Warmbloods and Thoroughbreds, are more prone to the condition due to their genetic makeup. Additionally, horses with a family history of navicular syndrome are more likely to develop the condition themselves.
Environmental Factors
Environmental factors, such as poor hoof care, excessive exercise, and inadequate nutrition, can also contribute to the development of navicular syndrome. Horses that are subjected to repetitive stress and strain on their hooves, such as those that engage in high-impact activities, are more likely to develop the condition. Similarly, horses that are fed a diet that is deficient in essential nutrients, such as calcium and phosphorus, may be more susceptible to navicular syndrome.
Biochemical Factors
Biochemical factors, such as inflammation and degeneration of the navicular bone and surrounding tissues, also play a crucial role in the development of navicular syndrome. This inflammation can be triggered by various factors, including trauma, infection, and genetic predisposition. Once the inflammation occurs, it can lead to degeneration of the navicular bone and surrounding tissues, resulting in pain, lameness, and reduced performance in affected horses.
Conclusion
Navicular syndrome is a complex condition that is caused by a combination of genetic, environmental, and biochemical factors. Understanding the causes of navicular syndrome is essential for preventing and treating the condition in horses. By identifying the underlying factors that contribute to the development of navicular syndrome, horse owners and equine professionals can take steps to prevent the condition and improve the overall health and well-being of their horses.
What Causes Navicular In Horses
Navicular syndrome is a common and debilitating condition affecting horses, particularly those involved in high-impact activities such as racing, jumping, and endurance riding. The navicular bone, located in the hoof, is a small, triangular bone that plays a crucial role in supporting the horse’s weight and facilitating movement. When the navicular bone becomes inflamed or damaged, it can cause significant pain and discomfort, leading to a range of symptoms and potentially even laminitis or navicular disease.

The Anatomy of the Navicular Bone
The navicular bone is situated in the hoof, specifically in the navicular fossa, a depression in the inner hoof wall. It is surrounded by a network of tendons, ligaments, and blood vessels that work together to support the bone and facilitate movement. The navicular bone is responsible for transmitting forces from the hoof to the rest of the leg, allowing the horse to bear weight and move efficiently.
The Causes of Navicular Syndrome
Navicular syndrome can be caused by a combination of genetic, environmental, and lifestyle factors. Some of the most common causes of navicular syndrome include:
- Genetic predisposition: Some breeds, such as Thoroughbreds and Quarter Horses, are more prone to navicular syndrome due to their genetic makeup.
- Hoof conformation: Hooves that are too long, too short, or have an irregular shape can put additional stress on the navicular bone, leading to inflammation and damage.
- Overuse and repetitive strain: Horses that engage in high-impact activities, such as racing or jumping, are more likely to develop navicular syndrome due to the repetitive stress and strain on the navicular bone.
- Poor nutrition and hydration: A diet that is lacking in essential nutrients, such as calcium and phosphorus, can contribute to navicular syndrome, as can inadequate hydration.
- Age and wear and tear: As horses age, their navicular bones can become more prone to inflammation and damage due to wear and tear.
The Symptoms of Navicular Syndrome
The symptoms of navicular syndrome can vary depending on the severity and progression of the condition. Common symptoms include:
- Pain and discomfort: Horses with navicular syndrome may exhibit pain and discomfort in the affected hoof, often accompanied by a reluctance to bear weight or move.
- Lameness: Navicular syndrome can cause lameness, which can range from mild to severe, depending on the extent of the damage.
- Swelling and heat: Inflamed navicular bones can cause swelling and heat in the affected area, which can be accompanied by pain and discomfort.
- Loss of performance: Horses with navicular syndrome may experience a decline in performance, as the condition can make it difficult for them to move efficiently or bear weight.
Diagnosis and Treatment of Navicular Syndrome
Diagnosing navicular syndrome can be challenging, as the symptoms can be similar to those of other hoof-related conditions. A veterinarian may use a combination of the following diagnostic techniques to confirm the diagnosis:
- Physical examination: A veterinarian will perform a physical examination of the horse, including a visual inspection of the hooves and a palpation of the navicular bone.
- Radiography: X-rays can be used to visualize the navicular bone and surrounding structures, allowing the veterinarian to identify any signs of damage or inflammation.
- Ultrasonography: Ultrasonography can be used to visualize the navicular bone and surrounding tendons and ligaments, allowing the veterinarian to identify any signs of inflammation or damage.
- Pain management: Medication can be used to manage pain and discomfort, allowing the horse to move more comfortably.
- Rest and rehabilitation: Rest and rehabilitation can help to reduce inflammation and promote healing in the affected area.
- Hoof trimming and shoeing: Hoof trimming and shoeing can help to redistribute pressure and reduce stress on the navicular bone.
- Surgery: In severe cases, surgery may be necessary to repair or remove the damaged navicular bone.
- Proper hoof trimming and shoeing: Regular hoof trimming and shoeing can help to prevent hoof-related problems and reduce stress on the navicular bone.
- Regular exercise and conditioning: Regular exercise and conditioning can help to strengthen the hooves and surrounding structures, reducing the risk of navicular syndrome.
- Proper nutrition and hydration: A balanced diet that includes essential nutrients, such as calcium and phosphorus, can help to promote healthy hooves and reduce the risk of navicular syndrome.
- Regular veterinary care: Regular veterinary care can help to identify any potential problems early on, allowing for prompt treatment and prevention of navicular syndrome.
