In the world I'm constructing, I have equine centaurs. I was going over my research and my notes for centaurs, and I realized that most horses are put down when they break a leg. Now, these centaurs live in a society on par to ours, and they wouldn't let someone die for such a simple injury, especially not when the humanoids are barely bothered by it.
I was thinking that maybe the centaurs could use canes, crutches, or walkers, due to the fact that they have a humanoid torso. However, I need some help with the design. Whatever you design, it needs to let the centaur walk without putting pressure on that last and it needs to let them heal properly. Please remember that they have difficulty reaching their back and back legs, but others could most certainly help them.
Their technology is at the same level as ours, save the fact that it's a touch more advanced in recycling and clean energy. There's also a ton of plastic, so you can definitely use that as a material if you want to.
