Introduction: Transforaminal lumbar interbody fusion (TLIF) surgery is well established for the
treatment of discopathy, foraminal disc herniation, and recurrent disc herniation.
At the Amiens university medical center, we have been using a robot-assisted technique
for performing the TLIF. The purpose of this study is to evaluate the radiological
and clinical outcome, specifically pain, of patients having undergone robot-assisted
TLIF. Materials and Methods: We performed a retrospective analysis of prospectively collected data of patients
having undergone minimally invasive (MI) robot-assisted TLIF between November 2014
and July 2018 in a French university medical center. In clinical consultations at
6 weeks, 12 months, and 24 months posttreatment, patients were assessed for back and
leg pain (on a visual analog scale), breached screws, and sagittal parameters. Results: A total of 136 pedicle screws were inserted with robot guidance into 32 patients.
Four of the patients required laminectomy before fusion. No pedicle breach occurred
for 94% of the screws, and no joint violation was observed for 90%. Lordosis was improved
in 78% of the cases. Conclusions: The robot provides valuable assistance during MI arthrodesis; it facilitates the
surgical procedure by preplanning the trajectory, providing instantaneous navigation
and tracking, and thus assure the accuracy of screw positioning.
