Leg Injuries in Horses

As the saying goes no foot no horse. Most horses have jobs that require athleticism. Additionally a horse with a severe lameness on one leg cannot survive for very long without causing irreparable damage to at least one of the other limbs. Knowing what causes leg injuries in horses how to identify lameness and when to call your veterinarian are keys to saving your horses athletic career and potentially its life.
What Are Leg Injuries in Horses?
Leg injuries in horses occur when any one or more structures in a horses limb is damaged by inflammation infection or trauma. This results in pain that can manifest as limping or lameness. Injuries can either be acute meaning they happened very recently or chronic meaning the 

injury developed over time. A good example of an acute injury is a hoof abscess while arthritis in a joint is more of a chronic condition.
Another way to think about leg injuries is considering what body structure may be affected. A little anatomy knowledge goes a long way to understanding the most common leg injuries. Horses have evolved to bear weight on one digit of each limb and all muscles that control movement are in the upper limb. That means that muscles above the knee in the front and the hock in the back attach to tendons and control flexion of joints. This allows for the finely tapered and fastacting limbs of the horse but these tendons and ligaments that run alongside are prone to injury.

Additionally these critical ligaments and tendons along with nerves blood vessels and joints are very close to the surface and often are involved in a wound. What may look like a minor cut may involve a critical structure.
Finally and most commonly are injuries contained within the hoof. The hoof is a rigid capsule
