The advantages offered by 3D printing in the medical world increase each day and this technology becomes an indispensable part of medical applications. Helping doctors before surgery thanks to its prototyping feature, 3D made a first in a tumor surgery occured in China.
There are many opinions on 3D’s development in medical world. It is widely thought that in a very near future, it will be possible to back up organs with 3D printing thusly the average human life will be doubled. There is time for that, but 3D is already accomplishing a lot in medical sector. One of these was in a sacrum tumor operation in Beijing QingHua ChangGeng Hospital.
Professor XiongHua Xiao, director of the department of orthopedics, led physicans Fei 
Songand Ji Zhao to successsfully complete an operation for a patient with a sacrum 1-2 giant cellbone tumor by removing the whole high sacral tumor and embedding 3D printed custom prostheses, establishing pelvic stability, whilst successfully maintaining the use of lower limbs, bladder and bowel functions. This is the first time this has been done successfully. The physicans cooperated with technists, and rebuilt the pelvis three-dimensional structure, repeated calculations and combined with clincial practice, they designed 3D printed custom artificial sacral vertebra.
According to professor Xiao, there are two therapeutic methods for large bone tumors. The first method is Excochleation, which is simple but has a high recurrence rate. Another method is full sacrectomy pelvic ring reconstruction surgery, which radically cures tumors but is highly difficult as there are few hosptials where this can be carried out. Moreover, this method requires the sacral nerve to be cut off, leaving patients with varying degrees of side effects.
