Arco cirúrgico em cirurgia de coluna: avaliação da qualidade da imagem e precisão

Abstract

ABSTRACT Introduction: The use of intraoperative imaging systems has become a recurring practice in spinal procedures, especially due to the need for greater control in implant placement. Among the resources used, the surgical arch (C-arm) stands out, whose application allows real-time visualization of anatomical structures. Objective: To describe the use of the surgical arch in spinal surgeries, with a focus on image quality and precision during instrumentation. Methodology: This is an integrative literature review, carried out in the PubMed, SciELO, and CAPES Periodicals databases. Descriptors in Portuguese and English were used, combined with the Boolean operator AND. Inclusion and exclusion criteria were applied, considering articles published between 2019 and 2024, in Portuguese and English, with free access to the full text. Results and Discussion: A total of 29.885 articles were located, of which 61 were screened by title and abstract. After applying the established criteria, 18 studies were included. The selected articles presented data on variations in image quality according to the C-arm model, acquisition protocols, radiation exposure, and implant placement accuracy. Operational aspects of the equipment, such as acquisition time, positioning, and navigation features, were also described. Conclusion: The description of the studies allowed us to characterize the use of the surgical arch in spinal procedures, highlighting the main technical and clinical variables associated with imaging and instrumentation. The organized data provide support for understanding the topic and decision-making in surgical practice.
