It results in an inability to flex the stifle, so the horse must walk with an extended hind leg. It is associated with straight hind limb conformation (post leg), poor muscling of the hind limb, stifle trauma, and genetics. [4] Fibrotic myopathy is caused by damage to the hamstring muscles, usually from trauma or intramuscular injection. [5]
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.
With this conformation, the horse can pull the hind legs further under the body, so there is a longer hind end stride, but the animal may not move in synchrony with the front. This will create an inefficient gait, as the hind end is forced to slow down to let the front end catch up, or the horse may take high steps behind, giving a flashy ...
Bone spavin indicated by A.. Bone spavin is osteoarthritis, or the final phase of degenerative joint disease (DJD), in the lower three hock joints.It usually affects the two lowest joints of the hock (the tarsometatarsal and the distal intertarsal joints), with the third joint, the proximal intertarsal, being the least likely to develop bone spavin.
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.
In cow-hocked horses, the hind hocks are too close together and point toward each other, with the feet too widely apart. It is a fairly common defect, and if the metatarsal bones are vertical, may not always cause lameness. A combination of cow- and sickle-hocks poses a greater risk. [1]
Each hind limb of the horse runs from the pelvis to the coffin bone. After the pelvis come the femur (thigh), patella, stifle joint, tibia, fibula, tarsal (hock) bone and joint, large metatarsal (cannon) and small metatarsal (splint) bones. Below these, the arrangement of sesamoid and phalanx bones and joints is the same as in the forelimbs.
The present-day conformation of the hoof is a result of a progressive evolutionary loss of digits I, II, IV and V of the basal pentadactyl limb, with changes in bones, joints, and the hoof capsule. The resulting conformation allows a heavy, strong body to move with high speed on any ground, and most efficiently on open, hard, flat areas like ...
