In general, a horse is more likely to survive if it is small in stature and has a good temperament that will tolerate the months of inactivity required for healing. Fractures that are open, comminuted (very fragmented), or located higher on the limb tend to have a poorer prognosis. [2]
As horses become older, the cannon bone becomes stiffer and thus bucked shins rarely occur again. Approximately 12% of horses that develop bucked shins go on to have stress or saucer fractures later. [46] Bucked shins force 7% of racehorses to retire. [47] Splints are new bone formation (exostoses) along the involved splint bone. [48]
Ignoring the disorientation and consequent stumbling of a horse who had just seconds before slammed his head against a metal door, horse industry theorists focus on the injury itself. Barbaro broke his right hind leg in more than 20 places: [ 4 ] a broken cannon bone above the pastern, a broken sesamoid bone behind the fetlock, and a broken ...
Equine polysaccharide storage myopathy (EPSM, PSSM, EPSSM) is a hereditary glycogen storage disease of horses that causes exertional rhabdomyolysis.It is currently known to affect the following breeds American Quarter Horses, American Paint Horses, Warmbloods, Cobs, Dales Ponies, Thoroughbreds, Arabians, New Forest ponies, and a large number of Heavy horse breeds.
Additionally, horses with a hind limb lameness will tend to reduce the degree of leg use. To do so, some horses will reduce the contraction time of the gluteals on the side of the lame leg, leading to a "hip roll" or "hip dip" and appearance that the hip drops a greater degree on the side of the lame leg. [10]
Many horses compete actively in demanding sports with sidebone, and are not hindered in any way. If the ossification is severe and associated with lameness then the prognosis is more guarded. Discovery of sidebone on an equine prepurchase exam without signs of lameness or local sensitivity should not affect the purchaser's opinion of the horse.
Prognosis can also vary depending on type and severity as well. However some signs of a positive prognosis may include, a horse being able to stay up and not lying down too much, keeping the horse quiet can also help with the healing factor, if the horse appears to be back to normal within 24 hours the prognosis outlook is better.
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 ...
