Recently, Shanghai Changzheng Hospital successfully completed the world's first full cervical spine 3D printing artificial vertebral body replacement surgery.
The patient Xiaowen was diagnosed as chondrosarcoma, a huge tumor was smashed in the cervical vertebrae, and the second to seventh cervical vertebrae were eroded. Chondrosarcoma is a malignant tumor that is highly recurrent, even with chemotherapy. The method of healing only replaces the six cervical vertebrae with a new one to exercise the function of the cervical spine to support the head.
It is understood that there has not been such an extraordinary cervical vertebral body replacement surgery in the medical field. Surgery faces a lot of risk, and accidents can occur if you are not careful. However, Xiao Jianru, who is the surgeon of this operation, said that he has accumulated rich experience through many years of spinal tumor surgery. He has a bottom in this surgery and is expected to have a success rate of about 90%.
In order to complete the operation better, Xiao Jianru led the team to prepare from three weeks ago. This time is mainly to customize the artificial vertebral body prosthesis. In the selection of materials, titanium alloy with high strength and hardness was selected as the best material for orthopedic implants. By comparing and analyzing Xiaowen's 3D model design of cervical vertebrae before surgery, I customized the same 3D printed titanium alloy artificial vertebral body. Xiao Jianru said that the 3D printed vertebral body prosthesis can be made into a sponge microporous structure. In this case, adjacent bones will grow inward. Ultimately, the fusion of the prosthesis and the human bone is achieved.
The operation was performed twice. The first operation was to remove and reconstruct Xiaowen's posterior approach. After a week, a second operation was performed to complete the resection and reconstruction of the anterior cervical and paravertebral tumors. It took 13 hours to complete the two operations.
Now, surgery has been a few weeks, Xiaowen recovered well. However, this cervical vertebral body replacement is more complicated. The 3D printed cervical prosthesis replaced by Xiaowen is one-piece, giving up flexibility but being relatively more stable. If Xiaowen wants to turn her neck, she needs to rotate the whole body together.
