In 2013, Doctors kept the hand of Chinese factory worker, Xie Wei, alive by stitching it to his left ankle and "borrowing" a blood supply from arteries in the leg.
Following the surgery, the hand itself felt warm, he said, but it was numb since no nerves were connected and only blood vessels were attached. His leg felt no different, he said, but was “heavier than usual.”
After a month, doctors were able to reattach the hand to his arm.
After being discharged, Xie Wei said he can twist his wrist to a certain degree, but doesn’t have full movement with his fingers.
Doctors told him a full recovery for the nerves in his hand should take about six months.
