BACKGROUND:: Three-dimensional visualization technique has been widely used in clinical treatment. Preoperative visualization technique allows safe demonstration on the complex spine fracture models, and also prepare screw placement scheme according to three-dimensional model of patients. OBJECTIVE:: To discuss the clinical result of treating short-segment lumbar vertebrae fracture with pedicle screw visualization. METHODS:: A total of 32 patients with lumbar vertebrae fracture were treated with 182 pedicle screws. Before the screw implantation, the structure of bilateral pedicle was observed using Mimics software and the implantation parameters were measured. The operation methods and related complications were told to the patients through the reconstructed three-dimensional images. The satisfaction of the patients, operation time, and the position of pedicle screws by postoperative CT scan were assessed. The percentages of anterior vertebral height and Cobbʼs angle were measured before operation, 2 weeks after operation and 8 months after operation. RESULTS AND CONCLUSION:: The excellent satisfaction rate of the patients was 100%, the mean operation time was 185 minutes, and 173 pedicle screws (95.1%) were totally inserted within the pedicle. All patients were followed up for 7-22 months. The results showed that the fracture healed well. The percent of anterior vertebral height and Cobbʼs angle at 2 weeks after operation were significantly decreased compared with them before operation (P < 0.05). There were no significant difference about the percent of anterior vertebral height and Cobbʼs angle between 2 weeks and 8 months follow-up (P > 0.05). Single-segment lumbar vertebrae fracture was well treated by the pedicle screw visualization technique. This method assists to make up preoperation plan, increase the rate of patientsʼ satisfaction, shorten operation time, and increase the accuracy of pedicle screw insertion.
