The primary objective of the present study was to evaluate the accuracy of a new robotic device when coupled with intraoperative flat-panel CT guidance. Screws (D8-S1) were implanted during two separate cadaver sessions by coupling the Rosa(®) Spine robot with the flat-panel CT device. Of 38 implanted screws, 37 (97.4 %) were fully contained within the pedicle. One screw breached the lateral cortical of one pedicle by <1 mm. The mean ± SD accuracy (relative to pre-operative planning) was 2.05 ± 1.2 mm for the screw head, 1.65 ± 1.11 for the middle of the pedicle and 1.57 ± 1.01 for the screw tip. When coupled with intraoperative flat-panel CT guidance, the Rosa(®) Spine robot appears to be accurate in placing pedicle screws within both pedicles and the vertebral body. Large clinical studies are mandatory to confirm this preliminary cadaveric report.
本研究的主要目的是评估一种新型机器人设备与术中平板CT引导相结合时的准确性。在两次单独的尸体实验过程中，通过将罗莎脊柱机器人与平板CT设备相结合，植入螺钉（D8-S1）。在38枚植入的螺钉中，37枚（97.4%）完全位于椎弓根内。一枚螺钉突破了一个椎弓根的外侧皮质不到1毫米。螺钉头部的平均±标准差准确性（相对于术前规划）为2.05±1.2毫米，椎弓根中部为1.65±1.11毫米，螺钉尖端为1.57±1.01毫米。当与术中平板CT引导相结合时，罗莎脊柱机器人在将椎弓根螺钉植入椎弓根和椎体中似乎是准确的。必须进行大型临床研究以证实这一初步的尸体报告。
