The five-year-old French boy saved his father's life by cycling to get help after he had a heart attack.
The father was given 30 years in jail for placing the boy in the machine and switching it on, the mother 12 years for aiding and abetting murder.
Using technology provided by US foundation e-NABLE, the hand cost less than 50 euros to produce and can be easily replaced as the boy grows.
The boy, on a family skiing holiday in Flaines near the Swiss border, apparently became lost on a piste before falling over a rock formation.
Critics say quizzing of pupil who said he was 'with the terrorists' after Charlie Hebdo murders is sign of 'collective hysteria' engulfing country.
The eight-year-old was killed after being hit in the head while sitting in the stands at a match in the Dunkirk arena.
