South Korea's "Korean Daily" reported on October 9 that Korean doctors successfully transplanted 3D printed sternum into a patient with advanced bone cancer. According to the South Korean news, in the future, South Korea will use 3D printing technology to create a lighter and stronger artificial bone for patients.
The patient in this case was a middle-aged man with bone cancer who had reached advanced stage. According to the diagnosis, the patient's cancer cells spread faster in the near future, and the doctor diagnosed his life with only 6 months. In order to control the spread of cancer cells and prolong the life of the patient, the doctor decided to perform surgery on the patient. Since the patient's cancer cells have spread to the inside of the sternum, if the artificial bone made of synthetic resin or metal material is difficult to grasp and easily breeds bacteria after surgical removal of the sternum, the research team used lighter and harder than ordinary metals. Better titanium. Titanium is harmless to the human body and is widely used in medical tools such as artificial spines.
The research team used CT to measure the patient's body shape and plotted the design. Then the design was entered into a 3D printer and titanium powder was added to make an artificial sternum. 3D printing is a technique that combines extremely thin metal deposits, and then irradiates a strong laser to melt the titanium surface and strengthen the density to make artificial bone. The research team also made a porous structure on the artificial bone to make it more elastic.
On September 19th, the Affiliated Hospital of the Central University of Korea transplanted a 3D printed sternum for the patient. The sternum size is just right for the patient's chest size. This operation is the first successful transplant of 3D printed sternum in Korea and the sixth successful case in the world.
