Lindsay Block of Oklahoma City with an i-Limb. She's been using prosthetics since she was six months old.
Edinburgh-based Touch Bionics has launched i-Limb, the "world's first commercially available bionic hand".
The hand is controlled via a myolectric electrode attached to the patient's skin, which picks up electrical signals from tiny muscle movements. Each finger has its own motor to provide lifelife movements.
The Touch Bionics site has a terrific picture gallery showing early users with their bionic hands.
The i-Limb is being unveiled at the 12th World Congress of the International Society for Prosthetics and Orthotics in Vancouver on 29 July.
Touch Bionics is a spin-off from the NHS.
