X线透视导航技术在创伤骨科的应用

X线透视导航技术对创伤骨科尤为重要。因为术前骨折块及骨折移位的方向可发生改变,所以需在术中将骨折块整复对位后,才能进行透视图像的获取和导航手术操作。X线透视导航技术的优点包括减少X线暴露的时间、准确放置植入物、术中适时测量评估及改善创伤骨科的微创操作。随着软件和硬件的不断改进及发展,许多需要术中X线透视监控的手术操作现在都可以借助X线透视导航技术完成。我们过去四年的临床经验已证实X线透视导航技术的优点及不断扩大的应用领域。X线透视导航技术在不断进展,因此需要更多的临床实践来评价此技术的使用价值。另外,X线透视导航系统在虚拟外科环境的外科培训和评价中发挥重要作用。这一技术将不仅为年轻外科医生提供实践机会,而且也将产生设计外科技术资格客观评价系统的新领域。

Application of fluoro-navigation technology in orthopaedics and traumatology

Fluoro-navigation technology becomes more and more important in orthopaedic surgery. Because of preoperative alteration in fracture fragment orientation it is necessary to complete the fracture reduction before fluoroscopic image acquisition and surgery assisted with navigation. The advantages of the fluoro-navigation technology include minimal X-ray exposure, accurate positioning of implants, real time interactive quantitative data of the images, and minimally invasive surgery. With further development and improvement of both software and hardware, many operations, which require X-ray monitoring, can be conducted with the help of fluoro-navigation technology. Our past 4-year clinical experiences confirm the above advantages and its potential applications. As the technology of fluoro-navigation is still under improvement, further evaluation and validation is necessary to confirm its clinical values. In addition, fluoro-navigationsystems may play an important role in virtual surgical training and assessment. It may provide not only training opportunities to young surgeons but also an objective assessment system for evaluating proficiency of surgical techniques.
