Every horse owner knows that understanding the anatomy of their equine companion is crucial for ensuring proper care and longevity. One of the terms that may often come up when discussing horse anatomy is the fetlock. But what exactly is a fetlock and why is it important for horse owners to be familiar with it? In this comprehensive guide, we dive deep into the world of fetlocks, discussing their function, importance, and potential health issues that can arise.

What is a Fetlock?
Fetlocks are the joints that connect the horse's cannon bone (the lower part of the leg) to the pastern bone (the bone just above the hoof). In simpler terms, a fetlock is essentially the horse's ankle. The fetlocks are present on both the front and hind legs of the horse.
These joints are a vital component of a horse's movement and play a significant role in their ability to bear weight, absorb shock, and perform various athletic activities. Like any other joint, the fetlock is composed of bones, ligaments, tendons, and cartilage.
The Structure of the Fetlock
- Bones: The fetlock joint is made up of three bones: the distal end of the cannon bone, the proximal end of the long pastern bone, and the two sesamoid bones. The sesamoid bones are small, rounded bones that help to support the joint.
- Ligaments: Ligaments connect bones to bones and provide stability to the fetlock joint. The suspensory ligament is the primary ligament that supports the fetlock and is crucial in maintaining its proper alignment.
- Tendons: Tendons are the structures that attach muscles to bones, allowing the joint to perform various movements. The superficial and deep digital flexor tendons are responsible for flexing the fetlock joint, while the extensor tendon enables the extension of the joint.
- Cartilage: Articular cartilage is present in the joint and helps in the smooth articulation of the bones, acting as a cushion and shock absorber during movement.
Potential Health Issues and Proper Care
As with any part of a horse's body, the fetlock can be subject to injuries and other health problems. Some common fetlock-related issues that horse owners should be aware of include:
- Strains and Sprains: Sudden stops, sharp turns, or simply stepping in a hole can cause a strain or sprain in a horse's fetlock. Regularly monitoring your horse's gait, checking for heat or swelling, and allowing time for proper healing are essential steps to addressing such injuries.
- Arthritis: Osteoarthritis in the fetlock joint can cause pain, inflammation, and decreased mobility in horses. Proper nutrition, joint supplements, and regular veterinary care can help prevent or manage arthritis in horses.
- Fetlock Joint Infections: Untreated wounds or punctures near the fetlock can lead to joint infections. Prompt attention to any cuts or scrapes and keeping the horse's living environment clean can prevent these infections from occurring.
- Hyperextension: Overextension or hyperextension of the fetlock joint can occur due to incorrect shoeing or constant overloading of the joint. Consultation with an experienced farrier and adjusting the horse's training regimen can correct this issue.
What Is A Fetlock On A Horse Example:
Imagine a showjumping horse taking off for a jump, then landing and making a tight turn to clear the next obstacle. During this sequence of events, the fetlocks play a critical role in supporting the horse's weight, absorbing the shock of landing, and facilitating the change of direction.
Understanding the structure and function of the fetlock joint is essential for horse owners to maintain their equine partner's health and comfort. Proper care, nutrition, shoeing, and training can help prevent numerous fetlock-related issues and ensure a long, active life for your horse.
