Eighteen-old-entrepreneur Leander, from Greece, discovers how sci-fi became reality, through the work of leading orthopaedic surgeon Professor Munjed Al Muderis. He has developed a new generation of implants for amputees which replaces the traditional socket based technology with a robotic prosthetic limb. We also hear about Professor Al Muderis’s life, and the journey he made as a refugee from Iraq to Australia. Made by BBC World Service and BBC Rewind. Produced by Tamsin Barber.
