Background
With the development of minimally invasive surgery, the pedicle screw internal fixation technology gradually becomes the routine operation of thoracolumbar surgery, and after thoracolumbar burst and fracture, broken bone blocks can move to the position of a vertebral canal, so that physical pressure is generated on the spinal cord, the cone or the cauda equina. This disease may cause the patient to lose some of his sensory or motor function and the spine may lose stability. The most effective auxiliary examination means for clinically confirming the disease is CT scanning. AO type A3 thoracolumbar vertebrae rupture fracture is characterized in that the fracture blocks burst to the periphery, and can press the dural sac and nerve root to generate nerve symptoms. And studies have shown that a3 type fracture is at risk for kyphosis. Surgical treatment is an effective solution to stress and stabilize the spine, and can be used for anterior and posterior surgery. Some patients receive posterior pedicle screw distraction reduction internal fixation surgery treatment and do not perform laminotomy decompression. In the past 20 years, the application range of the pedicle screw technology in clinic is increasingly wide, the posterior operation becomes more mature, and the purposes of fracture reduction and vertebral canal volume recovery are achieved. However, researchers find that a few patients still have residual obvious bone blocks at the position of the spinal canal as shown by the postoperative CT scanning, the diameter of the spinal canal does not reach the normal level or approach the normal level again due to the operation treatment, the position of the pedicle screw is not good, iatrogenic neurological impairment occurs, the relationship between the doctors and the patients becomes more tense, and the patients need to receive further treatment.
The root cause of this phenomenon is the key intraoperative process, pedicle screw implant surgery, which is the placement of pedicle screws for fixation through the pedicles into the vertebral bodies of the spine.

Such devices generally have only a perspective function, and to know whether the fractured bone has returned to a normal position, it is usually necessary to observe the "straight line" or "front arc" of the posterior edge of the vertebral body, so as to know the occupying space of the vertebral canal, which is related to the practical experience of the operator, the level of the perspective technician, the perspective definition of the C-arm, the perspective condition, and the like. In addition, the current CT scanning range of the movable C-shaped arm is small, the three-dimensional reconstruction dynamic interference is large, blind areas are more, the requirement of accurate evaluation in the operation cannot be met, and in addition, the professional levels of doctors are different, so that sequelae with different degrees can be caused in a plurality of operations.
