Revision surgery for adjacent segment degeneration (ASD) commonly requires exposing and removing the original fixation. To minimize trauma and to reduce the operation time and blood loss, we introduced a minimally invasive lumbar revision technique using cortical bone trajectory (CBT) screws assisted by three-dimensional (3D)-printed navigation templates. Methods: From April 2017 to October 2019, 18 patients with ASD underwent revision surgery with CBT screws assisted by 3D-printed templates in our hospital. All surgical data, including the operation time, blood loss, and incision length, were recorded. We evaluated the clinical efficacy using the visual analog scale (VAS), the Oswestry Disability Index (ODI), and the Japanese Orthopedic Association (JOA) score. X-ray and computed tomography (CT) scans were used to evaluate the stability of CBT screw fixation, the accuracy of screws, and the fusion rate. Results: The mean follow-up was 22.4±4.7 months (12-31 months). The VAS, ODI, and JOA scores were analyzed by SPSS 21.0 and showed significant improvement at 2 weeks and the last follow-up compared with preoperative data (P<0.05). Seventy-six CBT screws were inserted with navigation templates; 2 screws were Grade B, and the other screws were Grade 0 or A. Changes in intervertebral height showed good stability of CBT screw fixation (P>0.05). All the patients exhibited satisfactory fusion results. Conclusion: Revision surgery for ASD with CBT screws assisted by 3D-printed navigation templates has satisfactory clinical efficacy with the advantages of a short operation time, a small incision, and less blood loss.

“…Many researchers use 3D printing technology to make navigation templates to assist the placement of cervical pedicle screws, thoracic pedicle screws, CBT screws, or assist screw placement in special cases such as severe spinal deformity and complex revision surgery, which have been proven to have higher accuracy and safety and help reduce the radiation exposure of both the patients and operating room staff [17][18][19][20]. In this study, we used 3D printed navigation templates to assist the placement of CBT screws in the vertebral body which has been inserted pedicle screw in 18 cases, and the rest of the surgical procedures were the same as conventional techniques.…”
