[Intraoperative imaging with the mobile C-arm : Technique, image creation and radiation protection].

Imaging techniques in the discipline of orthopedics and trauma surgery are essential not only for making a diagnosis but also play a central role in the performance, documentation and monitoring of the corresponding treatment. Procedures such as open reduction and internal fixation (ORIF) and closed reduction and internal fixation (CRIF) of fractures, kyphoplasty and vertebroplasty as well as posterior stabilization of spinal fractures are carried out under X‑ray control. In the relevant operating rooms of emergency departments and operating theaters, mobile fluoroscopy devices are available, which due to their appearance are called C‑arms. These devices can be moved horizontally, vertically, and along the pivotal axis, enabling real-time imaging of joints and bones from various angles. This imaging enables minimally invasive surgical techniques as this often eliminates the need for extensive preparation and resulting in smaller wound defects compared to open surgical preparation. Additionally, surgeons can immediately assess and, if necessary, adjust the reduction outcome to achieve the best possible care and reduce the need for corrective interventions. With current C‑arms it is also possible to generate 3‑dimensional datasets, to enhance the assessment of implant positioning, particularly in complex intra-articular fractures. This availability helps avoid subsequent corrective interventions that would otherwise only be identified through postoperative computed tomography [1].      «
