| 摘要: |
| 椎弓根螺钉固定在脊柱外科手术中已被证实是一种可靠的技术方法，然而随着使用的越来越广泛，如破裂穿孔、重要神经和血管等解剖结构损伤等相关并发症也随之增多。已有许多学者通过一些辅助技术和手段来提高椎弓根螺钉系统的安全性和可靠性，如电生理监测技术、术中透视和CT等，虽然这些技术在一定程度上有所帮助，但是在临床实践中都存在一定局限性。电子导航装置（ECD）是一种新型的徒手探测装置，可以实时检测椎弓根壁的医源性断裂。本综述主要介绍了ECD的结构和作用原理及在脊柱外科领域应用中的优势和不足。 |

| Abstract: |
| Pedicle screw fixation has been proven to be a reliable technique in spinal surgery. It has been widely used, but the incidence of related complications increased, such as rupture, perforation and anatomical damage of important nerves and blood vessels. Scholars have adopted some auxiliary technologies and methods to improve its safety and reliability, such as electrophysiological monitoring technology, intraoperative fluoroscopy and computer tomography. Although these technologies are helpful to some extent, they all have certain limitations in clinical practice. Electronic conductivity device (ECD) is a new free-hand detection device, which can detect iatrogenic fracture of pedicle wall in real time. This review mainly introduces the structure and mechanism of ECD and its advantages and disadvantages in spinal surgery. |
