The pastern is a crucial part of a horse's leg, often overlooked but vital for its movement and overall health. Understanding its anatomy and potential problems is key for any horse owner or enthusiast. This article will delve into what exactly a pastern is, its function, and common issues that may affect it.

What is a Horse's Pastern?

The pastern is the area of a horse's leg located between the fetlock joint and the hoof. It's essentially the short, sloping part of the leg just above the hoof. Think of it as the horse's equivalent of our ankle. It's comprised of two bones: the short pastern bone (proximal phalanx) and the long pastern bone (distal phalanx), which is actually the coffin bone within the hoof. These bones are connected by joints and supported by ligaments and tendons.

The Importance of the Pastern

The pastern plays a vital role in shock absorption. Its sloping angle acts as a spring, cushioning the impact of each stride. This is crucial for protecting the horse's legs and joints from the constant stress of weight-bearing and movement. The pastern's flexibility also contributes to the horse's agility and smoothness of gait. Damage or abnormalities in the pastern can significantly impact a horse's comfort, performance, and soundness.

Common Pastern Problems

Several conditions can affect the horse's pastern, leading to lameness or discomfort. Let's examine some of the most prevalent:

1. Pastern Fractures

These can range from hairline cracks to complete breaks. They often occur due to trauma, such as a fall or a hard landing. Treatment can involve rest, bandaging, and sometimes surgery.

2. Pastern Injuries from Overuse

Repetitive stress can lead to inflammation and injury, particularly in performance horses. Conditions like tendinitis and desmitis are common. Rest, appropriate shoeing, and therapy are often part of the treatment.

3. Ringbone

Ringbone is a degenerative joint disease affecting the pastern bones. It can cause lameness and stiffness. Treatment often focuses on managing pain and inflammation.

4. Sidebone

Sidebone refers to ossification (the hardening) of the lateral cartilages of the coffin bone. It is often seen in horses used for heavy work.

5. Windpuffs

Windpuffs are soft swellings on the pastern that indicate inflammation of the tendon sheaths and joint capsules. While they can be harmless, they are indicative of potential underlying issues.

How to Identify Pastern Problems

Identifying pastern problems early is critical for successful treatment. Look out for:

• Lameness: Any signs of limping or favoring one leg.
• Swelling: Heat, swelling, or tenderness in the pastern area.
• Changes in Gait: Altered stride length or stiffness.
• Sensitivity to Touch: The horse might show discomfort when the pastern is palpated.

Preventing Pastern Issues

While not all pastern problems are preventable, there are steps owners can take to mitigate the risk:

• Regular Farrier Care: Proper shoeing is crucial for protecting the pastern.
• Appropriate Exercise: Avoid overworking or under-working the horse. Gradual increases in exercise intensity are recommended.
• Maintaining a Healthy Weight: Obesity puts extra stress on the pastern.
• Good Quality Bedding: Well-maintained bedding reduces the risk of joint and tendon injuries.

The horse's pastern is a complex structure crucial for movement and overall well-being. Understanding its anatomy and potential problems is vital for horse owners who want to maintain their horse's health and performance. By being vigilant and taking preventative measures, you can help keep your equine companion sound and comfortable.
