An old cancer patient of 41 years named Yuan, experienced the surgery at Peking University Third Hospital on 12th June, and he is able to walk by himself ever since the operation, stated by Xinhua news agency repeated the doctors’ words.

Throughout the 6 hour process, the copy, created from titanium powder, was introduced into his spine to block the void left after 5 tumor-affected vertebrae were taken out.

Without this operation, he would probably have been paralyzed, the doctors told.

In an earlier operation on 6th May, the tumor was detached, along with the posterior units of the 5 vertebrae. The space was occupied with titanium rods and some screws, which is a traditional treatment that preferably permits for patient mobility.

This 3D-printed vertebrae was utilized to support the backbone after elimination of the anterior sections in the June operation.

The typical solution of introducing a titanium tube into the lost section would have had foremost disadvantages.

The empty titanium tube is straight and it won’t match humanoid anatomical structure.

The titanium tube could also separate over time ever since the missing section of vertebrae is outsized, which would source to paralysis, based on Liu Zhongjun, the chief surgeon.

“The 3D printing vertebrae expertise offers an enhanced option. It allows us to create a replica resembling Yuan’s usual bone structures, both in length and shape, and it is secure,” Liu said.

The implant also has small pores that permit neighboring bone cells in usual vertebrae to cultivate. This will aid with blend of the replica and actual bones, he told.

Yuan was identified with chordoma, a sporadic cancer that can happen anywhere in the spine and even skull, in the month of December after undergoing acute lower back pain. In the month of January, he moved to the Peking University Third Hospital, which has an investigation team that has studied 3D-printing for orthopedics ever since 2009.

“I have faith in in the innovative technology. I have set myself for hazards. My disease can’t be cured in the conservative way and it makes no logic for me to postpone,” said Yuan, who is working in the catering business in Beijing and has a daughter of 5 years.

Yuan told he was able to walk with supports 2 weeks after the surgery.

A percentage of his medical costs were excused as of the experimental nature of the cure, he told.

The group developed only two 3D-printed vertebrae implant yields approved by the China Food and Drug Administration, which comprise a hip joint product and the vertebrae product permitted in the month of September 2015 and in the month of May correspondingly, the Xinhua report told.
