Regarding Radiation Exposure in Posterior Lumbar Fusion: A Comparison of CT Image-Guided Navigation Robotic Assistance and Intraoperative Fluoroscopy by Wang et al

摘要

The study published by Wang et al is highly interesting in our opinion and it highlights a crucial aspect of spinal surgery in terms of patient safety.1 Furthermore, it is beyond all doubt essential to assess the radiation exposure of conventional fluoroscopy-guided surgery to robotic navigational guidance and intraoperative computed tomography (CT) image-guided navigation. As stated by Wang et al and shown by various authors, the application of these techniques yields improved accuracy of pedicle screw positioning.1 However, there are some aspects of this study that need to be discussed, and we would like to compare our findings on radiation exposure in intraoperative computed tomography (iCT) versus fluoroscopy-assisted surgery to this study.2
