The purpose of this study was to clarify the learning curve for robotic-assisted spine surgery. We analyzed the workflow in robotic-assisted spine surgery and investigated how much experience is required to become proficient in robotic-assisted spine surgery.
The data were obtained from consecutive 125 patients who underwent robotic-assisted screw placement soon after introducing a spine robotic system at a single center from April 2021 to January 2023. The 125 cases were divided into phases 1-5 of sequential groups of 25 cases each and compared for screw insertion time, robot setting time, registration time, and fluoroscopy time.
There were no significant differences in age, body mass index, intraoperative blood loss, number of fused segments, operation time, or operation time per segment between the 5 phases. There were significant differences in screw insertion time, robot setting time, registration time, and fluoroscopy time between the 5 phases. The screw insertion time, robot setting time, registration time, and fluoroscopy time in phase 1 were significantly longer than those in phases 2, 3, 4, and 5.
In an analysis of 125 cases after the introduction of the spine robotic system, the screw insertion time, robot setting time, registration time, and fluoroscopy time were significantly longer in the 25 cases in the period initially after introduction. The times were not significantly different in the subsequent 100 cases. Surgeons can be proficient in robotic-assisted spine surgery after their experience with 25 cases.
本研究旨在阐明机器人辅助脊柱手术的学习曲线。我们分析了机器人辅助脊柱手术的工作流程，并研究了要达到机器人辅助脊柱手术熟练程度需要多少经验。
该数据来自于 2021 年 4 月至 2023 年 1 月在一家中心引入脊柱机器人系统后，连续接受机器人辅助螺钉植入术的 125 例患者。这 125 例患者分为 5 个阶段，每个阶段 25 例，并对螺钉植入时间、机器人设置时间、注册时间和透视时间进行比较。
5 个阶段之间的年龄、体重指数、术中出血量、融合节段数、手术时间和每节段手术时间均无显著差异。在螺钉植入时间、机器人设置时间、注册时间和透视时间方面，5 个阶段之间存在显著差异。第 1 阶段的螺钉植入时间、机器人设置时间、注册时间和透视时间明显长于第 2、3、4 和 5 阶段。
在引入脊柱机器人系统后对 125 例病例进行分析，在引入初期的 25 例病例中，螺钉植入时间、机器人设置时间、注册时间和透视时间明显较长。在随后的 100 例病例中，这些时间没有显著差异。在经验达到 25 例后，外科医生可以熟练掌握机器人辅助脊柱手术。
