Horses have zero muscles in their lower legs, meaning their hooves function as second hearts by pumping blood upward with each step; when a horse cannot move due to a broken leg, blood pools in the hooves, causing tissue death within 48 hours that spreads upward, making fractures a death sentence that requires euthanasia.

The Real Reason a Broken Leg Kills a HorseAdded:
A broken leg kills a horse, >> [music] >> but not how you think.
Their lower legs contain zero muscles, none.
Their hooves literally pump [music] blood back upward. Each step squeezes veins like a second heart.
Here's the thing. Stop moving. [music] Blood pools. Comment if you knew. Pooled blood starves tissue of oxygen completely. [music] Within 48 hours, the hooves start dying.
Tissue death climbs upward. No surgery fixes that. That's why vets euthanize [music] horses with broken legs. One fracture becomes a death sentence from the feet up. Laminitis [music] kills thousands yearly and nobody knows the cure. Like this if you'd never ride again.
