An Austrian man has voluntarily had his hand amputated so he can be fitted with a bionic limb.

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.

Andrei Ninu of German prosthetics company Otto Bock talks through the latest innovations in bionic hands with BBC reporter Neil Bowdler.

He shows how the next generation of hands will offer wrist movement which can be controlled by the amputee's own nerves, and demonstrates a prototype device which may enable the user of a bionic hand to "feel" objects.
