Robot assisted unilateral biportal endoscopic lumbar interbody fusion for lumbar spondylolisthesis: A case report

Objective: This paper reports a case of lumbar spondylolisthesis treated by unilateral biportal endoscopic lumbar interbody fusion (ULIF) surgery under the assistance of orthopedic robot. The clinical symptoms, surgical way and advantages of robotic surgery were reported conjunction with other literature. Method: One patient with lumbar spondylolisthesis underwent robot-assisted ULIF surgery after completing relevant examinations. The pain visual analogue scale (VAS) and Oswestry disability index (ODI) were recorded before and 3 days after surgery. The accuracy of pedicle screw placement was evaluated according to the Gertzbein-Robbins criteria. Result: The surgery went well. Compared with preoperative, postoperative VAS score and ODI index were significantly improved. 3 days after operation, X-ray and MRI showed that the position of the cage and internal fixation was accurate. The Gertzbein-Robbins score was Category A. Conclusion: Robot-assisted ULIF surgery provides a minimally invasive surgical approach for patients with lumbar spondylolisthesis due to its unique advantages of high precision and minimal invasiveness.
