The other day, my neighbor asked me to check out a horse he was thinking of buying. As I took a closer look, I noticed some signs of Navicular Disease, and my neighbor started to worry if that would rule out the purchase altogether.
I recommended passing on the horse with navicular disease. It can be a severe and debilitating syndrome that the horse may never fully recover. Navicular syndrome is a degenerative bone disease in the heel of the horse’s feet, typically the front feet.
Choosing the perfect horse is a challenge. Whether you’re drawn to a horse’s unique color or impressive pedigree, it’s important to make sure that the animal is healthy and sound. In this blog post, we’ll take a deep dive into Navicular Disease, a condition that affects many horses and can have significant implications for their well-being.
What Is Navicular Syndrome?
Navicular Disease is a multifaceted condition that impacts the navicular bone—a small yet essential bone in a horse’s hoof—and its surrounding structures. Specifically, this disease involves the gradual deterioration of the navicular bone situated at the rear of the coffin joint within the hoof.
As the bone degenerates, it causes soreness in the horse’s heel, leading to lethargic movement and lameness. The primary consequences of this condition include discomfort and lameness in the front feet, which can significantly affect a horse’s performance and overall well-being. Detecting this degenerative disease can prove challenging due to its often subtle and inconspicuous symptoms.
What Causes Navicular Disease?
While the exact cause remains unknown, experts believe it is multifactorial, involving genetics, conformation, and environmental factors. Horses with a genetic predisposition, such as Quarter Horses and Thoroughbreds, may be more prone to developing the condition. Additionally, conformational aspects like upright pasterns, small feet, and a large body mass can put added stress on the navicular bone, increasing the likelihood of Navicular Disease.
Environmental factors, including working on hard or uneven surfaces, can also contribute to the development of the disease. Inadequate hoof care, poorly fitted shoes, or excessive toe length can alter the biomechanics of the foot, increasing the strain on the navicular bone and the associated structures.
Symptoms of Navicular Disease
As a new horse owner, it’s crucial to familiarize yourself with the symptoms and signs of Navicular Disease. The primary indicator is lameness, which may be subtle or intermittent at first but may worsen over time. A horse with Navicular Disease may be reluctant to move forward, stumble, or take short, choppy strides.
A horse’s deteriorating navicular condition often starts with acute pain in the hoof. Of course, the horse lacks the ability for complex communication, so naturally, it can’t tell you what he’s feeling. So, you have to pay attention to the horse’s behavior and how it moves during its runs. Chronic forelimb lameness occurs more often in performance horses rather than in ones not stressed as much.
A horse with degenerated navicular bone expresses the condition by pointing one foot. It does this because, typically, the pain starts in one foot more acutely. When the animal runs, may stop often to rest and might alternate its weight from side to side. Horses may also switch lead legs when running, which can be an alarming symptom.
Since the heel is also degenerating, the horse typically lands toe-to-heel, contrasted with a healthy heel-to-toe landing, which the usual horse exhibits. Paying attention to the movements and overall condition of your horse will help you catch issues and plan possible treatment.
Other signs to look for include heat or swelling around the coronet band, uneven wear on the hoof wall or shoes, and a shortened stride when turning or moving on uneven ground. Remember that early detection is key to managing the condition effectively, so monitoring your horse closely for these signs can help ensure their long-term health and happiness.
The condition impacts horse’s feet in several ways:
- Significant degradation in the bone’s central cavity, where marrow is located.
- Damage to the cartilage fibers.
- Increased likelihood of new bone formation, sometimes known as medullary sclerosis.
- Pronounced displacement of tendons and flexor bone.
- Development of enthesophytes, or spurs, at the attachments of bones and ligaments. These abnormal bony outgrowths can cause discomfort in the horse.
About the navicular bone
To have a better understanding of the disease, one first needs to understand more about the affected structure.
- Etymology: The prefix “navicu” comes from Latin and means a small boat. The reason for this prefix is because the shape of the navicular bone resembles a canoe (a pointed vessel used to navigate the seas)
- Structure: The navicular bone is a small, flattened bone lined across the back of a coffin joint. It comprises a central marrow cavity for nerves and blood vessels to enter and a smoother backside, which acts as a gliding surface for the flexor tendon.
- Location: The navicular bone is located within the horse’s hoof, between the coffin bone and the pastern bone. The navicular bone is surrounded by many soft tissues, which help attach the bone to other ligaments. A soft sac called the navicular bursa acts as a cushion to the bone.
- Function: The navicular bone’s primary function is to act as a gliding surface for the digital flexor tendon. It helps the tendon to switch the angles and allows for movement.
Now as we have a better understanding of the structure and what it does, let’s look at the symptoms associated with navicular bone.
The Challenges of Owning a Horse with Navicular Disease
Owning a horse with Navicular Disease can be quite challenging due to its impact on the animal’s performance and overall quality of life. As the condition causes discomfort and lameness, the horse may experience a decline in its athletic abilities and daily activities.
This may limit the horse’s suitability for various disciplines such as dressage, jumping, or trail riding. Furthermore, the pain and limitations resulting from the disease can lead to a diminished quality of life, affecting the horse’s overall happiness and well-being.
Financial aspects: veterinary care and treatments
The financial aspects of managing a horse with Navicular Disease can be substantial, as the condition often requires ongoing veterinary care and treatment. Expenses may include diagnostic tests, such as X-rays, ultrasounds, or MRI scans, and regular visits from a farrier to ensure proper hoof care.
Additionally, treatment options like medications, corrective shoeing, and alternative therapies can be costly. The financial commitment of managing a horse with this condition should be carefully considered when deciding whether to own a horse with Navicular Disease.
The emotional toll on the owner
Beyond the practical challenges, owning a horse with Navicular Disease can take an emotional toll on the owner. Watching a beloved equine companion struggle with pain and discomfort can be distressing, and the uncertainty of the disease’s progression can be anxiety-inducing.
Additionally, the potential need to make difficult decisions regarding the horse’s future, such as retiring from competition or considering humane euthanasia, can weigh heavily on the owner’s emotions. It is essential for potential horse owners to be prepared for the emotional challenges of managing a horse with Navicular Disease.
Treatment and Management Options
Navigating the complexities of Navicular Disease requires a thorough understanding of the various treatment and management options available. Owners must explore both traditional and alternative therapies to find the most suitable approach for their horse’s specific needs.
Traditional treatments and therapies
