Abstract

Objective: Midline lumbar fusion with cortical bone trajectory(CBT) screw is a novel technique operation, robot system is the new developed system which can help CBT insertion. In this retrospective study, we compare the CBT accuracy by the assistance of navigation system and robot system. Clinical result is also compared.
Result: 55 patients were involved in this retrospective study, 29 patients are assisted by navigation system, 26 patients are by robot system. Mean follow-up is over 12 months. The mean VAS is significant improved at the final follow up for navigation group from 6.2±1.5 to 3.2±1.1(back pain), 7.5±0.9 to1.8±0.7(leg pain), same as the robot system from 6.8±1.5 to 2.9±0.8(back pain), 7.7±1.0 to 1.6±0.8 (leg pain). The JOA score pre-operation is 14.7±4.5 and 14.5±4.1 for navigation and robot system, at the final follow up, it is 24.3±4.2 and 23.9±4.4. the number of penetration cortex has no difference between 2 groups(n=0.363).
Conclusion: MIDLF with CBT screw is effective for the treatment of lumbar degenerative disease. Using navigation and robot system will help the insertion of CBT screw safety and accurate, robot can release the surgeon from part of aiming work.
