Axelrad said he was pleased to learn where and how Hung had been living for so many years, and to meet his family.
He added that returning the arm was certainly important but that "the event of him being with me and me be with him really overshadowed what the arm meant".
After the surgery, Hung spent eight months recovering and another six assisting American military doctors.
He spent the rest of the war offering private medical services in the town, and later served in local government for a decade before retiring on his rice farm.
