Gabriel Granados carries a ball during his physiotherapy session at Mexico City's Nutrition Hospital November 26, 2013. Two years after losing his arms to severe burns, a 53-year-old Mexican man is enjoying a new lease on life thanks to a rare double-arm transplant. Gabriel Granados arms were amputated just below the elbow after receiving a severe electrical shock. But in May 2012, nearly 20 medics, including five plastic surgeons, five nurses and three anaesthesiologists, performed a marathon 17-hour operation to attach two arms donated by a shooting victim. The operation was the first of its kind in Latin America with Granados having recovered the majority of movement in his arm from the operation following an extensive course of rehabilitation.
