Early Signs of Navicular Disease in Horses: Recognizing the Subtle Clues

Navicular disease, also known as navicular syndrome, is a debilitating condition affecting horses, particularly those involved in strenuous activity. This condition involves inflammation and degeneration of the navicular bone, a small bone located in the hoof. While the exact causes remain elusive, factors like conformation, genetics, and overuse play a role. Early detection is crucial for effective management and potentially preventing long-term complications. This article aims to shed light on the subtle, often overlooked, early signs of navicular disease in horses.

Recognizing the Early Warning Signals

Early stages of navicular disease can be challenging to diagnose as symptoms are often subtle and easily mistaken for other issues. However, a vigilant owner can identify these early clues:

1. Lameness: A telltale sign

• "Walking on Eggshells": One of the first indications is a subtle, shifting lameness, often described as a "short-strided" gait. The horse might appear stiff or reluctant to move, particularly after periods of rest or on hard surfaces. This type of lameness is often intermittent, becoming more pronounced with exertion and less noticeable at rest. (Source: "Navicular disease: a review" by J.A.W. Coetzee et al. 2015)
• "Hot" Hoof: The affected hoof might feel warmer to the touch than the other hoof. This indicates inflammation in the area.
• Increased Sensitivity: A horse with early navicular might show sensitivity when pressure is applied to the heel region of the hoof. This can be observed during shoeing or when the horse is standing on a hard surface.

2. Changes in Behavior:

• Reluctance to Move: The horse may become reluctant to move, especially after periods of rest or exercise.
• Reluctance to Turn: Turning tightly might be painful, leading to a wider turning radius.
• Change in Stance: Horses with navicular disease might adopt a characteristic "sawhorse" stance, where they shift their weight back onto their hindquarters to relieve pressure on the front hooves.

3. Other Physical Signs:

• Thickening of the Frog: The frog, the soft, V-shaped area in the sole of the hoof, may appear thicker or more prominent than usual.
• Changes in Hoof Shape: The hoof might become more contracted or exhibit uneven growth patterns, especially in the heel area.

Seeking Professional Diagnosis and Treatment

If you suspect your horse might be suffering from navicular disease, seeking professional help from a veterinarian is essential. They can perform a thorough physical examination, including hoof testing, palpation, and observation of movement. A veterinarian might also recommend additional diagnostic tools like:

• Radiography: To assess the navicular bone for signs of degeneration and inflammation.
• Ultrasound: To examine the soft tissues around the navicular bone.
• Blood Tests: To rule out other underlying health conditions.

Early Intervention: The Key to Success

Early diagnosis and intervention are critical for managing navicular disease effectively. The goal of treatment is to alleviate pain, reduce inflammation, and prevent further deterioration. Depending on the severity and the individual horse, treatment options might include:

• Rest: Resting the horse is essential to allow the inflamed tissues to heal.
• Shoeing and Farriery: Special shoes and trimming techniques can help distribute weight and reduce stress on the navicular bone.
• Medication: Nonsteroidal anti-inflammatory drugs (NSAIDs) can help reduce pain and inflammation.
• Alternative Therapies: Acupuncture, massage, and other alternative therapies may offer additional relief.

Early detection of navicular disease allows for a more effective treatment plan and potentially better long-term outcomes for your horse. Be a vigilant observer of your horse's behavior and physical condition. Early intervention is crucial for ensuring your equine partner continues to enjoy a happy and healthy life.
