Fluoronavigation is an image-guided technology which uses intra-operative fluoroscopic images taken under a real-time tracking system and registration to guide surgical procedures. With the skeleton and the instrument registered, guidance under an optical tracking system is possible, allowing fixation of the fracture and insertion of an implant. This technology helps to minimise exposure to x-rays, providing multiplanar views for monitoring and accurate positioning of implants. It allows real-time interactive quantitative data for decision-making and expands the application of minimally invasive surgery. In orthopaedic trauma its use can be further enhanced by combining newer imaging technologies such as intra-operative three-dimensional fluoroscopy and optical image guidance, new advances in software for fracture reduction, and new tracking mechanisms using electromagnetic technology. The major obstacles for general and wider applications are the inability to track individual fracture fragments, no navigated real-time fracture reduction, and the lack of an objective assessment method for cost-effectiveness. We believe that its application will go beyond the operating theatre and cover all aspects of patient management, from pre-operative planning to intra-operative guidance and postoperative rehabilitation.
荧光导航是一种图像引导技术,它利用在实时跟踪系统下获取的术中荧光透视图像以及配准来指导外科手术。在骨骼与器械配准后,就可以在光学跟踪系统下进行引导,从而实现骨折固定和植入物插入。这项技术有助于减少X射线暴露,提供多平面视图以监测植入物并进行精确定位。它允许进行实时交互式定量数据以辅助决策,并扩展了微创手术的应用范围。在骨科创伤领域,通过结合术中三维荧光透视和光学图像引导等更新的成像技术、骨折复位软件的新进展以及使用电磁技术的新跟踪机制,其应用可以得到进一步加强。普遍和更广泛应用的主要障碍在于无法跟踪单个骨折碎片、缺乏导航实时骨折复位以及缺乏成本效益的客观评估方法。我们相信,其应用将超越手术室,涵盖患者管理的各个方面,从术前规划到术中引导以及术后康复。
