Objective To analyze the clinical effect of pedicle screw fixation in the treatment of multi-segmental lumbar fracture and dislocation under the guidance of visualization technique. Methods A total of 21 patients with multi-segmental lumbar fracture and dislocation were selected from November 2012 to November 2013. Before the screw implantation, the structure of bilateral pedicle was observed through Mimics software and the implantation parameters were measured. The position of pedicle screws by postoperative CT scan, operation time, and the satisfaction of the patients were assessed. The percentages of anterior vertebral height and Cobb′s angle were measured before operation, 2 weeks and 8 months after operation. Results All patients were satisfied with informed consent score and the way of pedicle screw and the selection of plant were more reasonable. With better screw position, shorter operative time and less blood loss and adverse reactions, pedicle screw fixation achieved good effect. Conclusion With high security and considerable clinical value, pedicle screw fixation in the treatment of multi-segmental lumbar fracture and dislocation under the guidance of visualization technique has exact and good effecct.
