Summary: This study aimed to evaluate the accuracy and safety of navigation-based approaches compared to fluoroscopic techniques for cervical pedicle screw (CPS) placement. The results showed that navigation-assisted techniques had lower CPS misplacement rates and neurovascular complication rates compared to fluoroscopy-guided techniques.

Summary: This study evaluated the safety and efficacy of cervical pedicle screw (CPS) placement with O-arm navigation in the treatment of lower cervical fracture-dislocation. The results showed that CPS fixation had high accuracy in postoperative CT evaluation and there were no significant differences in clinical parameters and surgical complications compared to conventional lateral mass screw (LMS) fixation.

Summary: The study retrospectively analyzed the accuracy and reliability of posterior atlanto-axial fixation using spinal navigation combined with intra-operative 3D isocentric C-arm. The results showed that all cases achieved acceptable screw positioning, with no vertebral artery injury observed and no screw loosening or displacement at three-month follow-up.

Summary: This pilot study demonstrates improved angular precision in one of the first AR-navigated pedicle screw placement studies worldwide. Technical shortcomings need to be eliminated before potential clinical applications. In pedicle screw placement, the AR-navigated technique showed advantages in angular accuracy, but technical issues must be addressed before potential clinical implementation.

Summary: Computed tomography attenuation values were evaluated to compare the trajectories of cervical pedicle screw (CPS), lateral mass screw (LMS), and paravertebral foramen screw (PVFS) in vivo. Results showed that PVFS trajectories had higher attenuation values compared to LMS trajectories at all levels and higher values than CPS trajectories at C5 and C6 levels. Additionally, CT attenuation values were lower in the elder group (>60 years old) for all screw trajectories.

Summary: Posterior spinal fusion and segmental spinal instrumentation using pedicle screws (PS) is the most common procedure for correcting adolescent idiopathic scoliosis. This review compares the accuracy of different techniques, including computed navigation, robotic navigation, and free-hand technique, in placing the pedicle screws and reports the associated complications. The literature suggests that robotic navigation has the highest accuracy, followed by computed navigation and free-hand technique. However, all techniques have low complication rates. Robotic and computed navigation expose patients to higher levels of radiation compared to the free-hand technique.

Summary: This study retrospectively evaluated the accuracy of O-arm navigated CPS in 51 patients with a total of 156 screws. The results showed relatively low accuracy at the mid-cervical level, but the accuracy could be improved by converting the screw.

Summary: This paper describes a technique of minimally invasive, navigated, percutaneous pedicle screw fixation of the cervical spine and reports the initial experience with 27 patients. The results show that this technique can be performed safely with neurovascular complication rates comparable to traditional techniques.

Summary: This study compared the accuracy and clinical outcomes of robot-assisted and fluoroscopy-guided pedicle screw placement in posterior cervical surgery. The results showed that the robot-assisted group had higher success rate and accuracy, as well as less radiation time and dose, but longer operative time.

Summary: This study compared the accuracy of pedicle screw insertion using the Mazor system under different situations. The CT-to-fluoroscopy registration method showed superior accuracy compared to the preopCT/C-arm method. Percutaneous access was slightly better than open surgery. Axial shifts were more common than sagittal shifts. Using a quantitative method, only 10.8% of the screws were considered unacceptable, but with a stricter concept of inaccuracy, almost half were non-optimal. The O-arm registration method delivered more accurate implants than the preopCT/C-arm method.

Summary: By exploring the pedicle screw trajectory perpendicular to the coronal plane based on 3D models, individual navigation templates were developed to assist in surgery, resulting in shorter operative time, reduced intraoperative fluoroscopy, and improved safety of screw placement compared to traditional methods.

Summary: This study compared cervical sagittal alignment after posterior fusion surgery with CPS and LMS fixation. Results showed that SA correction was more reliable with CPS, but CL and SVA did not differ significantly between the two groups over time due to loss of correction.
