What does it mean to be positive to hoof testers?

Many mechanical tests help the diagnosis of foot lameness: Hoof tester: pressure is applied on the affected foot with a specific clamp to localize the painful area. Test is positive if the horse withdraws his foot under the pressure. This test is often positive on the heels of a horse with navicular disease.

How does a hoof tester work?

Hoof testers are large steel pincers designed to apply focal pressure to specific areas of the hoof. The primary goal in a hoof tester examination is to test for a pain response, usually indicated by the horse as a withdrawal of the limb.

What causes navicular disease in horses?

Navicular syndrome is a chronic degenerative condition that can cause lameness in the front legs. It is most commonly seen in competition horses and quarter horses. It may be caused by repetitive mechanical stress on the navicular bone, resulting in degeneration of tissues and ligaments in the heel.

How do you test for navicular in horses?

“Skyline” radiographs help veterinarians make a diagnosis of navicular disease. Typically, these radiographs include a single shot aimed across the bottom surface of the navicular bone (approximately 55° in reference to the horizontal).

Does my horse have laminitis or abscess?

Horses with an abscess should have a single painful spot, while those that are sore all over the hoof may have diffuse disease such as laminitis or a coffin bone fracture. Vets may use nerve blocks to numb the hoof.

How do you use a hoof gauge?

Green says farriers should set the bottom arm of the hoof gauge on the flat bottom of the foot, slide the device up against the toe and then place the top arm of the gauge up against the hoof wall to obtain an accurate measure of the angle.

What does a hoof tester look like?

Veterinarians and farriers often carry a tool that looks like a long-handled pincer with flat or rounded tips. This is a hoof tester, a device that can be used to apply gentle pressure to any spot on the horse’s sole, toe, or heel area.

What are the first signs of navicular in horses?

A history of intermittent low grade or recurrent lameness is suggestive of navicular disease. Affected horses often appear to place the toe down first, as if trying not to put weight on their heels (in contrast to laminitis), and the lameness is worse on the inside leg on a circle.

Can you still ride a horse with navicular?

Just like people with osteoarthritis, horses with navicular disease who are sedentary grow stiff and their body functions deteriorate. Turn your horse out in a pasture or paddock all day every day, if possible, and limit his time in the stall. If he’s still sound enough to ride, try to do so only on soft footing.
