The Daily Mail: A Chinese man known as Zhou lost his left hand in a factory accident involving a spinning blade.
Doctors kept his hand alive by attaching it to his ankle for several weeks.
Dr. Tang Juyu of the Xiangya Hospital in Changsha, China determined Zhou’s hand could only be reattached when the injured nerves and tendons in his wrist healed, Medical Daily reports.
So, the surgeon and his team attached the hand to Zhou’s right ankle, allowing the hand to receive blood from the leg’s arteries.
Dr. Juyu said,
In normal temperatures, a severed finger should resume blood supply within 10 hours. The time is even shorter for a separated limb. If it falls short of blood for long, the tissues dies and it would be impossible to get it back.
The hand was grafted onto the ankle for over a month and then reattached to Zhou’s arm in an extremely complex procedure lasting 10 hours.
Zhou is currently able to make minute finger movements, but he will reportedly not have full use of his hand until he completes a significant amount of rehabilitation.
This was at least the second time Dr. Juyu and his team grafted a severed hand onto an ankle.
The previous patient, who lost his hand in a work accident in 2013, also required a month of healing before the limb could be reattached.
