Someday, robotic prostheses and exoskeletons might be so commonplace that amputees will no longer have to use something that resembles a suction cup on a stick. In the interim, though, there’s ITAP. The technology, which stands for intraosseous transcutaneous amputation prosthesis, is a type of prosthetic that plugs right into an amputee’s bone. This allows them to actually feel that artificial limb and walk like they normally would with two healthy legs, and it also prevents chafing and skin issues common among those who use prostheses. For ITAP to organically merge with one’s bones, its creators from the University of London and the Royal National Orthopaedic Hospital drew inspiration from deer antlers. Like antlers, the metal part sticking into the bone is porous, inviting soft tissue to invade it and seal any surface or opening that could be infected by bacteria.
