horse back leg anatomy
• Sudden hind leg lameness in horses results in an uneven gait. The x-ray beam is centered at the coronary band. Since the form of the horse's legs is closely associated with the function, it is not an overstatement to stress their importance in the overall well-being of the horse. If you lift your horse's leg and manipulate his hoof while palpating the pastern with your other hand, you should be able to feel the play of the extensor branches of the suspensory ligament angling forward over the sides of the pastern just below the fetlock. Bog spavins are unsightly, but many horses perform well despite them. It also includes the joints of the hip, stifle, hock, fetlock, pastern, and coffin. Horse rear legs The horse leg anatomy in the rear includes the bones of the pelvis (the ilium, ischium and pubic bones), femur, tibia, fibula, metatarsus and the phalanxes. This protects the cassette from the weight of the horse. They are joined to the spine through the sacroileac joints and allow transfer of propulsion to the hind legs. The back’s “position” depends on the neck’s “position” All this thanks to the “supraspinous ligament”. One of it's main functions is to cause the rear leg to become stiff when the foot is on the ground. bones of the pelvis (the ilium, ischium and pubic bones), femur, tibia, fibula, metatarsus Horse, back leg bone structure.huesos de miembro posterior, un caballeo. The digital extensor is the large tendon that runs down the front of the horse's leg. Hock: The tarsus (hind limb comparable to the human ankle and heel) – a ;large joint in the hind leg. Members of this order walk on either one toe (like horses) or three toes (like rhinos and tapirs). The knee joint, or carpus, is composed of the carpal bones and allows movement in the foreleg. The hind limbs are involved in approximately 20 percent of cases, with the hock and stifle joints being the main problem areas. When the horse is viewed from the front, the observer can drop an imaginary line from the top center of the leg at chest level down through the forearm, knee, cannon, and fetlock to the center bottom of the hoof. Hind Legs’ Engagement. The reciprocal apparatus of the hind limb aids in preventing fatigue when the horse is standing and insures that there will be reciprocal flexing of the hock joint when the stifle joint is flexed or that the hock will extend when the stifle extends, thereby preventing injuries. The pastern bones occur above and below the pastern joint with the long pastern on top, between the fetlock and the joint, and the short pastern below the joint connecting to the coffin joint. The flexing can be more subtle, however, appearing occasionally and may be more obvious when the horse is asked to step back or turn sharply. This quiz has tags. They also join the common digital extensor tendon where the two branches attach to the long pastern bone. A horse with good conformation is going to have well-formed, symmetrical legs. This ligament is a wide, elastic, tendon-like band that runs from the back of the cannon bone and attaches to the back of the upper third of the long pastern bone.

The navicular bone functions as a pully for the deep flexor tendon that wraps around the navicular and is attached to the pedal bone. Origin - the ischial tuberosity (pelvic head). The tibia forms the upper part of the hind limb from the stifle to the hock. Collateral ligaments are important in maintaining stability in joints such as the fetlock, carpus, elbow, hock and stifle. The suspensory ligament in the horse is a strong, broad, fibrous anatomical structure that attaches to the back of the cannon bone just below the knee — the origin of the ligament. The tendons and ligaments on a weight-bearing pastern are difficult to discern because they hug the bone surfaces so tightly. #19-The stifle is the largest single joint in the body. The majority of the power of movement should come from the rear legs. A horse with proper leg angles has less stress on its joints, and the legs are better able to absorb the concussion from the impact of each hoof as it hits the ground. The horse's legs and feet are actually quite hardy. The patella, or kneecap, is the bone in the stifle joint above the fibula and tibia. All rights reserved. Keep in mind there are layers of muscles. Equine Juvenile Arthritis - Causes and Treatments, Horse Conformation - Head, Neck and Shoulders, Limping Horse? The power propulsion system and major defensive tool, a horse's rear legs are functional and beautifulNew window. The superficial digital flexor tendon runs down the back of each leg and forms the rear outline of the leg. The cannon bone is a weight-bearing bone in the lower leg and stretches from the knee joint to the fetlock joint. Hand-walking and shoeing changes can help your horse in the meantime. The ischium forms the point of the buttock. This is controlled by the stay apparatus, which is similar to our own kneecap. This is in contrast to even-toed ungulates, members of the order Artiodactyla, which walk on cloven hooves, or two toes. The pedal bone is a hoof-shaped structure in the foot that serves for the attachment of tendons and ligaments from the muscles in the forearm. When the hind leg is viewed from behind, the imaginary line will run from the back of the hindquarters along the back of the gaskin, hock, cannon, fetlock, and pastern to the bulbs of the heels. Occasionally, a stifle joint becomes locked due to overstraining or genetic joint problems. Beneath the superficial tendon is the deep digital flexor. The suspensory apparatus of the fetlock absorbs the shock of concussion and supports the fetlock, which is the joint subject to the greatest stress. Tendons serve as either flexors or extensors, depending on whether they bend the limb or straighten it. Good breeders focus on leg conformation to improve with each breeding.
