Navigation systems are supposed to increase precision and support surgeons while they perform certain interventions. 2D, or nowadays 3D, systems are used in image-based approaches. Image-free navigation uses 3D printing.
There are several studies on navigation procedures in trauma surgery. In contrast to limb surgery, the use of 3D navigation in pelvic and spine surgery is already well established. Navigation is especially regularly used to treat fractures of the posterior pelvic ring and for posterior stabilization of the cervical spine.
To be able to utilize navigation systems optimally, the learning curve should be completed, and the technique should be used regularly. In addition, the surgeon should know the surgical technique without navigation in order to recognize potential errors of the navigation.
Advantages include increased patient safety, reduction in radiation exposure and less invasive surgical procedures. However, among other disadvantages, initial costs are high.
导航系统旨在提高精准度，并在外科医生进行某些干预操作时提供支持。基于图像的方法中使用二维或如今的三维系统。无图像导航则采用3D打印技术。
关于创伤外科手术中导航程序的研究有多项。与四肢手术不同，三维导航在骨盆和脊柱手术中的应用已相当成熟。导航尤其常用于治疗骨盆后环骨折以及颈椎的后路稳定。
为了能够最佳地利用导航系统，应完成学习曲线，并且该技术应定期使用。此外，外科医生应了解无导航情况下的手术技术，以便识别导航的潜在错误。
优点包括提高患者安全性、减少辐射暴露以及使手术侵入性更小。然而，除其他缺点外，初始成本很高。
