Sidebone

What is it?

Sidebone refers to hardening of the cartilages either side of the hoof’s coffin bone. Experts don’t know why the normally springy tissues become hardened or become bone. Theories include genetics, trauma to the hoof, poor hoof and leg conformation, poor trimming, and poor shoeing. Sidebone is most common in heavy breeds like draft horses, warmbloods, and cob-type ponies.

What can we do about it?

Sidebone isn’t a cause of significant lameness, but was found on an X-ray of the feet. No specific treatment is required. If lameness is restricted to the feet, however, damage to nearby cartilages or fractures of these cartilages could be an issue. Ultrasound, nuclear scintigraphy, or advanced techniques like MRI and CT can help determine the activeness of the Sidebone in a horse’s body and if there is any inflammation.

What other information do I need?

Sidebone cartilage tissue is also known as collateral cartilages. Quittor refers to a condition in which the cartilages of the hoof become infected. This condition can cause severe lameness. It should be treated immediately to prevent further tissue destruction.

I’m Allison, born and raised in San Diego California, the earliest memory I have with horses was at my grandfather’s farm. I used to sit at the stable as a kid and hang out with my Papa while he was training the horses. When I was invited to watch a horse riding competition, I got so fascinated with riding!
