摘要：Pedicle screw technology has been increasingly common in spinal surgery due to its advantages of three-column fixation, immediate fixation to the spine, strong orthopedic force, and significant improvement in fusion rate. To improve the insertion accuracy, a variety of screw systems have been proposed. The traditional freehand insertion has a rather long learning curve, and the contribution of clinical experience to the improvement of the insertion accuracy is limited. However, guided by imaging technologies, insertion accuracy is improved signiifcantly. X-ray assisted screw insertion is the most common technology due to its lower economic cost and easier operation of the assisted equipment, but its accuracy in more complex cases like scoliosis needs to be improved. The new computer-aided screw technology can provide accurate navigation in the surgery, but it is not common now due to high costs. Combined with 3 D printing technology, the digital navigation templates assisted technology can set tailored navigation template for each patient by accurate pedicle screw placement at an inexpensive price. However, this technique has not been widely used since it costs much time for preoperative designing. In this paper, the research development of freehand ( unassisted ) fixation, fixation by computer assisted navigation, fixation assisted by X-ray, and digital navigation template technique are summarized. Evaluation standards on fixation accuracy of pedicle screws are discussed to show the whole picture of pedicle screw placement for spine fusion.
