Medical problems that are more common in horses with long, sloping pasterns include: Bowed tendon; Sesamoiditis; A fracture of the sesamoid bones found at the back of the fetlock, should the joint hyperextend to the point where it touches the ground. This is especially likely if the horse is tired, such as at the end of a race.
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 ...
Sesamoid bones: Bones embedded within a tendon. The horse's proximal digital sesamoids are simply called the "sesamoid bones" by horsemen, his distal digital sesamoid is referred to as the navicular bone. Ligaments and tendons hold the skeletal system together. Ligaments hold bones to bones and tendons hold bones to muscles.
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 pasterns are weak and unable to stabilize fetlock drop, so the horse is predisposed to ankle injuries, especially in speed events where the sesamoids are under extreme pressure from the pull of the suspensory. This can cause sesamoid fractures & breakdown injuries. May be associated with high or low ringbone.
There are between one and four sesamoid bones associated with the stifle joint in different species. These sesamoids assist with the smooth movement of tendon/muscle over the joint. The most well-known sesamoid bone is the patella, more commonly known as the "knee cap". It is located cranially to the joint and sits in the trochlear groove of ...
Skeletal fractures account for 87% of fatal injuries. [citation needed] When a horse's leg hits the ground at racing speed on a straightaway, it bears a load that is three times its weight (with the exception of harness racing). When negotiating a turn, centrifugal force increases the load to between 5 and 10 times body weight.
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.
