A worker operating a machine in a family workshop in China accidentally cut off his hand -- which doctors are able to save by grafting it onto his lower calf. The transplanted hand has survived and the point of reattachment is healing, It took doctors about half an hour to resume blood supply to the severed right hand. On Dec. 4, Tang and his surgical team spent nine hours restoring the hand to its original limb. [Photo/XXCB.cn]
