[Comparison of accuracy between robot-assisted and fluoroscopy-guided percutaneous pedicle screw placement for treatment of lumbar spondylolisthesis].

Abstract

Objective: To explore the clinical application value of the spinal robot-assisted surgical system in mild to moderate lumbar spondylolisthesis and evaluate the accuracy of its implantation. Methods: >0.05). The screw insertion angle was measured by CT, the accuracy of screw implantation was evaluated by Neo's criteria, and the invasion of superior articular process was evaluated by Babu's method. Results: =0.003). Conclusion: Compared to fluoroscopy-guided percutaneous pedicle screw placement, robot-assisted percutaneous pedicle screw placement has the advantages such as greater accuracy, lower incidence of screw penetration of the pedicle wall and invasion of the facet joints, and has a better screw insertion angle. Combined with MIS-TLIF, robot-assisted percutaneous pedicle screw placement is an effective minimally invasive treatment for lumbar spondylolisthesis.
