What Is The Navicular Bone?
The navicular bone is a small, boat-shaped bone located in the heel of the horse’s foot. It plays a crucial role in the horse’s movement and weight-bearing, as it helps to distribute pressure and absorb shock. The navicular bone is surrounded by a number of tendons, ligaments, and bursae (small fluid-filled sacs) that work together to facilitate movement and reduce friction.
What Causes Navicular Syndrome?
Navicular syndrome is a complex condition that can be caused by a combination of factors. Some of the most common causes include:
-
Overuse and repetitive strain: Horses that are subjected to repetitive strain and overuse, such as those involved in high-impact activities like jumping or racing, are more likely to develop navicular syndrome.
-
Conformational defects: Horses with conformational defects, such as club foot or ringbone, are more prone to developing navicular syndrome.
-
Foot imbalance: Horses with foot imbalance, where the hooves are uneven or poorly trimmed, can develop navicular syndrome.
-
Trauma: Trauma to the navicular bone or surrounding tissues can cause navicular syndrome.
-
Genetics: Some breeds, such as Quarter Horses and Thoroughbreds, are more prone to developing navicular syndrome due to genetic factors.
-
Age: Navicular syndrome is more common in older horses, as the navicular bone and surrounding tissues undergo wear and tear over time. (See Also: Why Do Horses Spook So Easily)
Symptoms Of Navicular Syndrome
The symptoms of navicular syndrome can vary in severity and may include:
-
Lameness: Navicular syndrome can cause significant lameness, which can range from mild to severe.
-
Pain: Horses with navicular syndrome may exhibit pain or discomfort in the heel area, which can be evident through changes in behavior or gait.
-
Heat and swelling: The heel area may become hot and swollen due to inflammation.
-
Reduced performance: Horses with navicular syndrome may exhibit reduced performance or reluctance to move.
-
Changes in gait: Horses may alter their gait to avoid putting pressure on the affected heel.
Diagnosis Of Navicular Syndrome
Diagnosing navicular syndrome can be challenging, as the symptoms can be similar to those of other conditions. A veterinarian will typically use a combination of the following methods to diagnose navicular syndrome:
-
Physical examination: A veterinarian will perform a thorough physical examination to assess the horse’s lameness and identify any areas of pain or discomfort.
-
Imaging studies: X-rays, ultrasound, and MRI scans can be used to visualize the navicular bone and surrounding tissues, allowing the veterinarian to identify any abnormalities or damage.
-
Nerve blocks: A veterinarian may use nerve blocks to numb the nerves in the heel area, allowing them to isolate the source of the pain and lameness.
-
Blood tests: Blood tests can be used to rule out other conditions that may be causing the symptoms.
Treatment And Management Of Navicular Syndrome
Treatment and management of navicular syndrome typically involve a combination of the following:
-
Rest and rehabilitation: Affected horses should be given a period of rest and rehabilitation to allow the navicular bone and surrounding tissues to heal.
-
Pain management: Pain management medications, such as anti-inflammatory drugs, may be used to alleviate pain and discomfort.
-
Corrective shoeing: Corrective shoeing can help to redistribute pressure and alleviate strain on the navicular bone.
-
Physical therapy: Physical therapy, such as massage and acupuncture, can help to reduce pain and inflammation.
-
Surgery: In severe cases, surgery may be necessary to repair or remove damaged tissues.
Prevention Of Navicular Syndrome
While navicular syndrome can be challenging to prevent, there are several steps that can be taken to reduce the risk of developing the condition:
-
Proper hoof care: Regular trimming and shoeing can help to prevent foot imbalance and reduce the risk of navicular syndrome.
-
Regular exercise and conditioning: Regular exercise and conditioning can help to strengthen the navicular bone and surrounding tissues.
-
Avoid overuse: Avoiding overuse and repetitive strain can help to reduce the risk of navicular syndrome.
-
Genetic testing: Genetic testing can help to identify horses that may be more prone to developing navicular syndrome due to genetic factors.
-
Early detection: Early detection and treatment of navicular syndrome can help to prevent long-term damage and improve outcomes.
Prognosis And Outcome
The prognosis and outcome for horses with navicular syndrome vary depending on the severity of the condition and the effectiveness of treatment and management. In general, horses with mild cases of navicular syndrome may be able to return to full function with proper treatment and management. However, horses with more severe cases may experience ongoing lameness and discomfort, and may require ongoing management and treatment to maintain a good quality of life.
