Abstract：Objective: To explore the application value of digital orthopedics technology in the individualized treatment of thoracolumbar fractures. Methods: A total of 10 patients with thoracolumbar vertebral fracture were enrolled from December 2015 to June 2017, who had to be operated on internal fixation of thoracolumbar fractures. The DICOM data were obtained preoperatively by means of CT scan. Injured and surrounding vertebra were reconstructed in patients with the aid of digital orthopedics technology and related software (Mimics 17.0, Geomagic studio12.0, Unigraphics NX10.0, Rapid prototyping technology). According to the related vertebral sclerotin condition in three-dimensional space, the operative plan was made, the nail canal designed, the navigation template done and the operation procedure simulated. Intra-operative thoracolumbar vertebral fracture operations were implemented with pedicle navigation template. The postoperative effect of screw placement and its complications were recorded. Results: The thoracolumbar vertebral fracture operations in 10 cases were successfully completed. Totally 64 pedicle screws were placed. In accordance with the Gertzbein and Robbins rating standard: 53 cases of pedicle screws were Grade I, 9 were Grade II and 2 were Grade III, with an accuracy of screw placement being 96.9% (62/64). All patients received 12-24 months’ follow-up, average time 13.0±6.3 months, and no complications related to screw placement such as screw false placement, spinal cord injury, internal fixation failure and so on were found. Conclusion: Digital orthopedics technology provides a kind of new change and method for the individualized and lean treatment of thoracolumbar fractures.
