An Austrian man has voluntarily had his hand amputated so he can be fitted with a bionic limb.
The patient, called "Milo", aged 26, lost the use of his right hand in a motorcycle accident a decade ago.
After his stump heals in several weeks' time, he will be fitted with a bionic hand which will be controlled by nerve signals in his own arm.
The surgery is the second such elective amputation to be performed by Viennese surgeon Professor Oskar Aszmann.

Such bionic hands, manufactured by the German prosthetics company Otto Bock, 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.
