Robotic-Assisted Spine Surgery: Role in Training the Next Generation of Spine Surgeons

Abstract

Objective: This study aimed to assess the degree of interest in robot-assisted spine surgery (RASS) among residents and to investigate the learning curve for beginners performing robotic surgery. Methods: We conducted a survey to assess awareness and interest in RASS among young neurosurgery residents. Subsequently, we offered a hands-on training program using a dummy to educate one resident. After completing the program, the trained resident performed spinal fusion surgery with robotic assistance under the supervision of a mentor. The clinical outcomes and learning curve associated with robotic surgery were then analyzed. Results: Neurosurgical residents had limited opportunities to participate in spinal surgery during their training. Despite this, there was a significant interest in the emerging field of robotic surgery. A trained resident performed RASS under the supervision of a senior surgeon. A total of 166 screw insertions were attempted in 28 patients, with 2 screws failing due to skiving. According to the Gertzbein-Robbins classification, 85. 54% of the screws were rated as grade A, 11. 58% as grade B, 0. 6% as grade C, and 1. 2% as grade D. The clinical acceptance rate was approximately 96. 99%, which is comparable to the results reported by senior experts and time per screw statistically significantly decreased as experience was gained. Conclusion: RASS can be performed with high accuracy within a relatively short timeframe, if residents receive adequate training. © 2024 by the Korean Spinal Neurosurgery Society.
