200. Comparison of freehand, fluoro-guided, CT navigation, and robot-guided TLIF and ALIF

Screw placement in transforaminal interbody fusion (TLIF) and anterior lumbar interbody fusion (ALIF) can be done with open free hand (FH), fluoroscopy-guided (FG), spinal navigation (NAV), or robotic guided (RG) techniques. Varied techniques may affect perioperative (periop) outcomes. Few studies c...

Description
Summary:Screw placement in transforaminal interbody fusion (TLIF) and anterior lumbar interbody fusion (ALIF) can be done with open free hand (FH), fluoroscopy-guided (FG), spinal navigation (NAV), or robotic guided (RG) techniques. Varied techniques may affect perioperative (periop) outcomes. Few studies compare all four guidance techniques. Compare the perioperative outcomes between FH, FG, NAV, and RG TLIF and ALIF. Single center retrospective cohort study A total of 1,646 patients who underwent 1-2 level TLIF or 1-3 level ALIF from 2012-2019. Outcomes: registration failure, operative time (OT), radiation dosage (RD), estimated blood loss (EBL), length of stay (LOS), and periop complications, and retursn to OR up to 90 days. Patients undergoing 1-2 level TLIF or 1-3 level ALIF were included. Analysis of variance (ANOVA) and χ2test were used to analyze differences in outcomes with significance set at p
