Osselet is arthritis in the fetlock joint of a horse, caused by trauma. [1] Osselets usually occur in the front legs of the horse, because there is more strain and concussion on the fetlock there than in the hind legs. The arthritis will occur at the joint between the cannon bone and large pastern bone, at the front of the fetlock.
Splints is an ailment of the horse or pony, characterized by a hard, bony swelling, usually on the inside of a front leg, lying between the splint and cannon bone or on the splint bone itself. It may be "hot," meaning that it occurred recently and is still painful; or "cold," meaning that the splint has completely recovered and there is no ...
Bucked shins: pain, heat, and swelling over the dorsal surface of the cannon bone most commonly seen in racehorses. This complex disease process, called "dorsal metacarpal disease," involves inflammation of the periosteum , subperiosteal hematoma, and microfractures to the cortex of the underlying bone.
Zygomatic bones: attach to the temporal bone to form the zygomatic arch (cheek bone) Palatine bones: form the back of the hard palate; Sphenoid bone: formed by fusion of the foetal basisphenoid and presphenoid bones, at the base of the skull. Can become fractured in horses that rear over backwards. Vomer: forms the top of the inside of the ...
Skeleton of the lower forelimb. Each forelimb of the horse runs from the scapula or shoulder blade to the third phalanx (coffin or pedal) bones. In between are the humerus (arm), radius (forearm), elbow joint, ulna (elbow), carpus (knee) bones and joint, large metacarpal (cannon), small metacarpal (splint), sesamoid, fetlock joint, first phalanx (long pastern), pastern joint, second phalanx ...
The concussion comes from the rigorous training regimen that two-year-olds often face and inability of the bone to adapt fast enough. 70% of young Thoroughbred racehorses in training develop the problem, usually in the first six months. As horses become older, the cannon bone becomes stiffer and thus bucked shins rarely occur again.
Heel pain is very common in horses with navicular syndrome. Lameness may begin as mild and intermittent, and progress to severe. This may be due to strain and inflammation of the ligaments supporting the navicular bone, reduced blood flow and increased pressure within the hoof, damage to the navicular bursa or DDF tendon, or from cartilage erosion.
Lameness is most commonly associated with injury to synovial joints, or those joints containing articular cartilage, a joint capsule, and a synovial membrane.Joint disease may affect the joint capsule and synovial membrane, articular cartilage, subchondral bone (the bone underneath the cartilage), menisci, or any ligaments associated with the joint.
