Navicular Disease: A Common and Challenging Condition in Horses

Introduction
Navicular disease (ND) is a debilitating condition that affects the navicular bone in horses. This small, V-shaped bone is located in the hoof, behind the coffin bone. ND occurs when the navicular bone becomes inflamed and damaged, leading to pain and lameness.

Development of Navicular Disease
The exact cause of ND is unknown, but several factors are believed to contribute to its development, including:

• Conformation: Horses with certain hoof conformations, such as long toes and low heels, are more prone to developing ND.
• Overuse: Excessive stress on the navicular bone can damage it and lead to inflammation. This can occur due to excessive training or riding on hard surfaces.
• Trauma: A direct blow to the hoof can fracture the navicular bone and trigger the onset of ND.

Relationship between Navicular Disease and Navicular Syndrome
Navicular syndrome is a broader term that encompasses navicular disease and other conditions that cause similar symptoms. These symptoms include:

• Heel pain: Horses with ND often show signs of pain when pressure is applied to the heels of their hooves.
• Lameness: Lameness is a common symptom of ND and can range from mild to severe. Horses may be reluctant to walk or trot, and they may have a short, choppy stride.
• Stiffness: Horses with ND may also exhibit stiffness in their gait. They may have difficulty rising from a sitting or lying position.

Diagnosis and Treatment of Navicular Disease
Diagnosing ND can be challenging, as it often relies on a combination of clinical signs and diagnostic tests. These tests may include:

• Radiographs: X-rays can reveal changes in the navicular bone, such as bone spurs or erosions.
• Ultrasound: Ultrasound imaging can provide a detailed look at the navicular bone and soft tissues surrounding it.
• Nerve blocks: Blocking nerves in the hoof can help identify the source of pain and confirm a diagnosis of ND.

Treatment for ND aims to relieve pain, reduce inflammation, and improve mobility. Options may include:
