When was the first successful spinal transplant in China?

As early as June 1970, China Shanghai Orthopedic Research Institute and Shanghai Ruijin Orthopedic Hospital successfully performed spinal transplantation for a 27-year-old male patient with giant cell tumor of spinal bone after tumor resection. This operation was replaced by medical stainless steel artificial vertebral body. Two months after operation, the patient's lower limb paralysis disappeared and he was able to get up after half a year. He has worked for many years.
