Since the invention of 3D printing technology, many fields apply this technology to carry out new work, medical treatment is no exception, in 2014 I applied for the subject of “cervical pedicle screws in the production of digital modules in the nailing application research and clinical promotion” was approved by the Inner Mongolia Autonomous Region Science and Technology Department funding, the first to carry out this technology in Inner Mongolia, the patient’s CT scan data imported into the MINICS software, the establishment of a model of cervical vertebrae and the patient’s The patient’s CT scan data is imported into the MINICS software to establish a cervical spine model identical to the patient’s, and the pre-setting of the nail path is carried out under the computer, the designed nail path template is printed out with a printer, and it can be applied in the surgery after being sterilized with plasma, and the pre-produced template is put on the atlantoaxial spine of the patient to place the nail accurately, avoiding the risk of damaging the blood vessels and nerves during the surgery, so far, 12 cases of atlantoaxial spine surgeries have been done and the satisfactory efficacy was obtained, and the postoperative radiographs show that The postoperative radiographs show that the nail placement is more precise than the traditional surgery, thus making the difficult and risky surgery simpler, safer and more precise.
