Comparative StudyComparison of Superior-Level Facet Joint Violations Between Robot-Assisted Percutaneous Pedicle Screw Placement and Conventional Open Fluoroscopic-Guided Pedicle Screw Placement.
To compare the superior-level facet joint violations (FJV) between robot-assisted (RA) percutaneous pedicle screw placement and conventional open fluoroscopic-guided (FG) pedicle screw placement in a prospective cohort study. ⋯ Compared to the open FG technique, minimally invasive RA spine surgery was associated with fewer proximal facet joint violations, larger facet to screw distance, and higher intra-pedicle accuracy.
