Three Austrians have replaced injured hands with bionic ones that they can control using nerves and muscles transplanted into their arms from their legs.

The three men are the first to undergo what doctors refer to as "bionic reconstruction," which includes a voluntary amputation, the transplantation of nerves and muscles and learning to use faint signals from them to command the hand.

Previously, people with bionic hands have primarily controlled them with manual settings.

"This is the first time we have bionically reconstructed a hand," said Dr. Oskar Aszmann of the Medical University of Vienna, who developed the approach with colleagues. "If I saw these kinds of patients five to seven years ago, I would have just shrugged my shoulders and said, 'there's nothing I can do for you.'"

He said while some patients might be candidates for a hand transplant, that has its own complications, including having to take anti-rejection medicines for the rest of their lives.

Aszmann and colleagues described the cases of the three men in a report published online in the journal Lancet. The men decided on amputation only after having the bionic hand strapped onto their injured hand, to see how the robotic one might function.

For Milorad Marinkovic, 30, who lost the use of his right hand in a motorbike accident more than a decade ago, the bionic hand has allowed him to hold things like a sandwich or bottle of water and more importantly, to play with his three children.

"I can throw things, but it is harder to catch a ball, because my right hand is still not quite as quick and natural (as my left)," said the Vienna based-clerk.

Dr. Simon Kay, who authored an accompanying commentary and performed Britain's first hand transplant, said there would always be major limits to bionic hands. He pointed out that the brain has thousands of ways to send messages to the human hand but that a robotic prosthetic can't handle such complexity.

"The question is always going to be: How do we get the message from the mind to the metal?" he said.

Patients like Marinkovic, however, have few complaints about the bionic hand, which proved especially popular with his son. When he first got the device, his son, then 4, would put on the bionic hand and proudly walk around with it, telling the other kids in his kindergarten class that "my father is a robot."

Marinkovic says using his bionic hand is nearly as natural as using his uninjured hand.

"I can do almost everything with it. I just don't have any feeling in it."

An unrelated study published last year gave patients some feeling in a prosthetic hand by relaying signals to the brain in a temporary experiment and other replacement hands can do things like grip objects but are controlled externally.

Aszmann estimated the new procedure costs around $33,960. The study was paid for by groups including the Austrian Council for Research and Technology Development and a laboratory which receives funds from Otto Bock, maker of the prosthetics used.

    Three Austrians (not Australians) have had bionic hands replace their injured ones through a process of voluntary amputation, transplantation of nerves and muscles (from their legs), and training. They will have to take anti-rejection medication for the rest of their lives, but the hands have allowed them to grip things and play with their children. It restores almost all the functionality back into the hand, although the feeling is gone-but the procedure costs almost 34,000 dollars. I thought this article was another advancement in science which sets humans apart. Although the question of whether that is good or bad still does not have a suitable answer.

    It's awesome that people had Bionic Reconstruction and received a second chance by having a working arm. Now they can do push ups easier and pat their head and rub their stomach at the same time.

    I think it was right for these men to get new bionic hands to replace the old injured ones. I also thought this process was cool because it was the first time the people reconstructed a bionic hand.

    It is truly amazing how technology has prospered and really taken a turn for the better. Years from now there will be options to be able to get any type of bionic part.

    How did they injure their hands? Why did they get the ones that they can control using nerves and muscles transplanted into their arms from their legs?

    The scientists had to undergo programming a piece of metal to do exactly what an arm and hand does. this means years of work, also you literally have to cut your arm off

    It is amazing how technology can help people 50 years ago nobody would of even dremt about something like bionic hands and arms.Technology can be a really big help.

    It'd be pretty hard to get the metal to obey the commands of living nerves, it is, after all, stronger than our nerves. The metal doesn't respond well to the skin's commands, because it isn't the natural order of things.

    this is surprising because its like building a robot but only their head is, its just weird to have a robot head but if they needed it they should have it plus they still have mind so they can think. its good to have a head instead of being dead.

    I think that we've came a long way from having wooden arms/ legs to robotic ones that transform us into bionic people. I think it can probably be better than real human parts as far as abilities go.
