Overview

Multicenter retrospective study reveals superior pedicle screw accuracy with robotic assistance compared to O-arm navigation during lumbar fusion, suggesting robotic systems enhance precision.

Key Points

  • To compare the accuracy and safety of robot-assisted versus navigation-guided percutaneous pedicle screw placement during minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF).
  • Multicenter, retrospective study of 100 patients undergoing 1- to 3-level MIS-TLIF between 2019 and 2022 for symptomatic spinal stenosis and spondylolisthesis.
  • Patients were grouped into robot-assisted (RA, n = 42) and O-arm navigation (ON, n = 58) cohorts to place a total of 514 percutaneous pedicle screws.
  • Postoperative CT scans were evaluated to determine screw placement accuracy and safety according to the Gertzbein and Robbins classification.
  • Clinically satisfactory screw accuracy was achieved in 100% of the RA group compared to 92.1% of the ON group (p < 0.001).
  • Overall operative time was similar between groups (263.54 ± 114.33 minutes in RA vs 243.4 ± 68.96 minutes in ON, p = 0.2821), though RA took significantly longer for 2-level MIS-TLIF (324.67 ± 101.25 vs 266.4 ± 66.38 minutes, p = 0.0264).
  • Neither group experienced medial breaches or required revision surgeries or reoperations for screw malposition.
