Horses need 4 legs to survive

All the recent news of Barbaro, the horse that won the Preakness Stakes and borke it's leg had me wondering... why do they have to put down horses that break one of it's legs.
I did some research and it was quite interesting and thought I'd share it.
Horses have two small arteries in their legs, and when a horse breaks a leg, the blood flow to the lower limb might be impeded.
That's what you worry about as life-threatening
If this kind of injury happened to a human, we'd be put up in bed for six weeks. But you can't do that for a horse.
A horse's physiology and temperament are not designed for long stretches of inactivity. A horse with a severely injured leg will try to put weight on it; if a horse is forced to recline, its internal organs may not react properly.
Why broken legs are life-threatening for horses
Kentucky Derby winner Barbaro broke three bones in his right rear leg in Saturday's Preakness Stakes. It is a life-threatening injury because a horse must heal fast and well enough to have four weight-bearing limbs. Why that's difficult:
Can't keep a horse lying down: Horses are continuous grazers. Sedating a horse enough that it will lie down for a long period of time disturbs its gastrointestinal tract.
Can't keep a horse still: Horses are animals of flight. When horses get in unfamiliar circumstances, they revert to nature and want to run.
Can't keep a horse off his feet: Whenever they are under stress, horses want to stand. In a sling, a horse will struggle until it gets its feet back on the ground.
Artificial limbs aren't practical: Artificial limbs have been tried repeatedly, with limited success. Horses require four limbs to spread their weight. When they overload a limb, it is extremely painful.
Equilibrium is crucial: Equilibrium is so finely tuned in a horse that it needs all four legs for long-term survival.
