When was the first successful human limb reattachment surgery performed?

A landmark in microsurgery occurred in 1962, when surgeons in Boston successfully reattached a severed human arm/hand using techniques that later became central to limb replantation. This kind of surgery depended on the ability to repair tiny blood vessels and nerves. The development of microsurgery in the 1960s made limb reattachment increasingly possible. It was a turning point for trauma and reconstructive surgery.
