Innovations in intraoperative imaging lead to major changes in orthopaedic surgery. In our setting, a 3D flat-panel c-arm (Artis zeego) is mounted on a robotic arm offering an integrated aiming tool (Syngo iGuide). Our aim was to investigate the feasibility of Syngo iGuide for pedicle screw placement in comparison with fluoroscopic screw implantation.
In 10 lumbar models, 100 screws were implanted. In 5 models, a standard fluoroscopic technique was used. Syngo iGuide was used in all other models. Afterwards, CT-scans were performed and screw accuracy was investigated.
The procedure time for the new technique was significantly longer in comparison with the standard technique. The post-operative CT showed the same accuracy in both groups.
Syngo iGuide proofed feasible for percutaneous implantation of pedicle screws in anatomic models. Syngo iGuide can be a help for screw implantation in difficult anatomic regions without the need of an additional navigation system.
术中成像技术的创新给骨科手术带来了重大变革。在我们的研究中，一台三维平板C型臂（Artis zeego）安装在一个提供集成瞄准工具（Syngo iGuide）的机器人手臂上。我们的目的是研究与透视下螺钉植入相比，Syngo iGuide在椎弓根螺钉置入中的可行性。
在10个腰椎模型中植入100枚螺钉。在5个模型中采用标准透视技术。其他所有模型均使用Syngo iGuide。之后，进行CT扫描并研究螺钉置入的准确性。
与标准技术相比，新技术的手术时间明显更长。术后CT显示两组的准确性相同。
Syngo iGuide在解剖模型中经皮植入椎弓根螺钉是可行的。Syngo iGuide有助于在困难解剖区域进行螺钉植入，而无需额外的导航系统。
