Abstract
Introduction: This study was conducted to evaluate reliability and precision of a novel intraoperative computed tomography(iCT)-based navigated procedure to minimally invasive positioning of cervical pedicle screws. Methods: Ten cases were included. Pedicle screws were positioned percutaneously with iCT-based navigation between C3-C7 (Airo mobile CT scanner, Brainlab, Munich, Germany). In the control CT scan screws were assessed regarding affection of the pedicle cortices and neuroforamina. Image quality was evaluated with a subjective Likert-Scale (0–5) and a semi-objective Assessability score (0–4). Results: 40 screws were placed. Average subjective image quality was 3.57 ± 1.0, average assessability score was 3.59 ± 0.73. 23 screws (58 %) were positioned centered in the pedicle. 4 screws perforated the medial wall by more than 2 mm [2.7–2.9]. 9 screws were positioned laterally by more than 2 mm [2.5–4.9]. No postoperative neurological deficits were observed. Conclusion: Even in shallow anatomic structures, iCT-navigated visualization of instruments and implants allows for minimally invasive surgery.
