Osseointegrated prosthetics, artificial limbs that fuse to the bone, have been touted as the future of prosthetics -- and rightly so. There are a number of possible benefits, both for humans and animals, including prosthetic limbs that attach without chafing or irritation and limbs with more natural ranges of motion.
