Introduction:  The purpose of this study was to clarify the learning curve for robotic – assisted spine surgery.   Our experience with robotic assisted spine surgery in first 100 cases over 5 months period in single tertiary care center.  To know the experience required to become proficient in robotic assisted spine surgery.

Methods:  the data was obtained from consecutive 100 patients who underwent robotic assisted screw placement soon after introducing a spine robotic system at a single center from October 2025 to February 2026. 100 cases were divided into 4 phases with 25 cases each and compared for surgical time, accuracy of screw placement, post op pain, radiation exposure

Results:  there was no significant differences in intra operative blood loss, operation time per segment fused. There is significant decrease in surgical time, radiation exposure, post op pain and improved accuracy of pedicle screw placement.

Conclusion: in an analysis of 100 robotic assisted spine surgeries in the initial phases from phase 1 and 2 there was increase in operative time, increased post op pain, increased radiation exposure. In subsequent phases from phase 3 and 4 significant improvements in operative time, post op pain, radiation exposure and accuracy of pedicle screw placement. Surgeons should be proficient with regional anatomy and other techniques of pedicle screw placement if any break down of robo intraoperatively.
