A 26-year-old man in Austria who lost the use of his right hand in a motorcycle accident ten years ago has decided to undergo "elective amputation," after which he will be fitted with a bionic hand controlled by nerve signals from his own arm. German prosthetics company Otto Bock makes the bionic hands; BBC News reports the prosthetics can "pinch and grasp in response to signals from the brain that are picked up by two sensors placed over the skin above nerves in the forearm."
This will be the second such surgery performed by Professor Oskar Aszmann, of Vienna.
A 24-year-old Austrian man named Patrick was the first patient in the world to choose to have his hand amputated, again by Professor Aszmann, and a bionic replacement fitted. He lost the use of his left hand after being electrocuted at work.More here, and there's video of the bionic hand in use by Patrick, here.
