Shoe Boil

The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus, which locks major joints in the limbs, allowing horses to remain standing while relaxed or asleep. The limbs play a major part in the movement of the horse, with the legs performing the functions of absorbing impact, bearing weight, and providing thrust. The hooves are also important structures, providing support, traction and shock absorption, and containing structures which provide blood flow through the lower leg.

Good conformation in the limbs leads to improved movement and decreased likelihood of injuries. Large differences in bone structure and size can be found in horses used for different activities, but correct conformation remains relatively similar across the spectrum. Structural defects, as well as other problems such as injuries and infections, can cause lameness, or movement at an abnormal gait. Injuries to and problems with horse legs can be relatively minor, such as stocking up, which causes swelling without lameness, or quite serious. Even non-fatal leg injuries can be fatal to horses, as their bodies are designed to bear weight on all four legs and serious problems can result if this is not possible.
