Compared with the FGF group, the RAF group had a lower fluoroscopy frequency [14 (12–18) vs. There was no significant difference in the mean computed tomography (CT) Hounsfield unit (HU) values, operation duration, or length of hospital stay between the groups. The patients’ sagittal kyphosis Cobb angles (KCA), anterior vertebral height ratios (VHA), and screw loosening rate were evaluated by radiographic data 1 year after surgery. Pedicle screw length, diameter, and pedicle screw placement accuracy were assessed. Demographics, clinical characteristics, and radiological features were recorded. MethodsĪ retrospective cohort study was conducted to evaluate 70 consecutive patients. The purpose of this study is to compare the sizes (diameter and length), placement accuracy and the loosening rate of pedicle screws using robotic-assisted versus conventional fluoroscopy approaches for thoracolumbar fractures. However, it remains unclear whether the robot really optimize the selection of screw sizes and enhance screw stability. There has been increased development of robotic technologies for the accuracy of percutaneous pedicle screw placement.
