Introduction: There has been no report comparing the accuracy of percutaneous pedicle screw (PPS) insertion between fluoroscopy and intraoperative CT navigation.
Methods: Eighty-three patients who underwent indirect decompression with extreme lateral lumbar interbody fusion (XLIF) and PPS were studied. Eighty-three patients were divided into three groups; Dual-position (DP) -PPS group to insert PPS under fluoroscopy in prone position (36 patients); Single position (SP) -PPS group to insert PPS under fluoroscopy in lateral decubitus position (19 patients); SP-PPS+O-arm group in which PPS is inserted in the lateral decubitus position under intraoperative CT navigation (28 patients). We compared the accuracy of PPS insertion among the three groups.
Results: The results showed that the screw insertion angle of the SP-PPS group was smaller than that of the DP-PPS group, but there was no significant difference in the screw perforation rate among the three groups (DP-PPS: 4.0%, SP-PPS: 5.1%, SP-PPS+O-arm: 3.8%).
Conclusion: We think that the SP-PPS procedure under fluoroscopy was considered to be a useful method because it does not require an expensive surgical support device and has the same screw accuracy as the DP-PPS procedure.
