Navicular syndrome, often called navicular disease, is a syndrome of lameness problems in horses. It most commonly describes an inflammation or degeneration of the navicular bone and its surrounding tissues, usually on the front feet. It can lead to significant and even disabling lameness. [1]
Navicular disease or navicular syndrome: a catch-all phrase used to describe pain in the palmar hoof which was originally attributed to damage to the navicular bone. MRI has since shown that navicular syndrome may be caused by damage to any of the structures within the hoof, including the navicular bone, the navicular bursa, the coffin joint ...
Evaluation of the horse's conformation, hoof balance, and shoeing is often a first step in treatment of lameness. A correct, balanced trim is a key component of lameness treatment and prevention. Some cases of lameness, such as angular limb deformities and navicular syndrome , are best managed with special trimming and shoeing.
The horse has a sesamoid bone called the navicular bone, located within the hoof, that lies on the palmar aspect of the coffin joint between the second phalanx and third phalanx (coffin bone). The navicular bone in the horse is supported by the distal sesamoidean impar ligament and two collateral sesamoidean ligaments.
In veterinary medicine, tiludronic acid is used to treat navicular disease and bone spavin in horses. Its tradenames are Tildren and Equidronate. It is approved for treatment of navicular disease and distal, tarsal osteoarthritis in Europe, [1] and was approved for treatment of navicular disease in the United States in 2014.
A horse can live with laminitis for many years, and although a single episode of laminitis predisposes to further episodes, with good management and prompt treatment it is by no means the catastrophe sometimes supposed: most horses suffering an acute episode without pedal bone displacement make a complete functional recovery. Some ...
It forms the "forearm" of the horse along with the ulna. Ulna: caudal to the radius, it is fused to that bone in an adult horse. Shoulder joint (scapulohumeral joint): usually has an angle of 120-130 degrees when the horse is standing, which can extended to 145 degrees, and flexed to 80 degrees (such as when the horse is jumping an obstacle).
While the horse uses muscles throughout its body to move, the legs perform the functions of absorbing impact, bearing weight, and providing thrust. [17] Good movement is sound, symmetrical, straight, free and coordinated, all of which depend on many factors, including conformation, soundness, care and training of the horse, and terrain and footing.
