A Kansas man who lost his legs and several fingers to E. coli has been fitted with X-Fingers, mechanical devices that he powers with the remaining muscles in his hand. While computerized prostheses are available for whole-hand amputees, advanced prosthetics are not really available for people missing just a few fingers, according to practitioners at Hanger Prosthetics, who fit Martinez with the X-Fingers. Martinez, who uses microprocessor-controlled prosthetic feet, said, "It actually feels like your fingers. That's the amazing part. It feels as though I have fingers."
