Summary: This study compared the efficacy and safety of freehand atlantoaxial pedicle screws with custom 3D printed navigation template screws in the treatment of upper cervical fractures. The results showed that using individualized 3D printed guide can significantly improve the safety, efficacy, and accuracy of the screws.

Summary: The use of 3D printed navigation template for pedicle screw placement in type II odontoid fractures resulted in reduced surgical time, blood loss, and improved safety and accuracy of screw placement. Patients in the guiding group showed better improvement in VAS scores and ASIA scores at 1 week post-surgery.

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 used finite element analysis to compare the biomechanical properties of a novel posterior fixation device with a conventional pedicle screw system in lumbar fusion surgery. The results showed that the new device can effectively reduce the range of motion of the spine and provide comparable stability to the traditional screw system when used with different interbody devices.

Summary: The aim of this study was to verify the optimization algorithm for pedicle screw placement in a cadaveric study and to quantify the effect of optimization. Results showed that optimization of the pedicle screw trajectory improved the pull-out strength and pull-out strain energy only for vertebrae with high elastic modulus values.

Summary: Expandable pedicle screws have advantages in treating lumbar spine fractures, but there is a lack of preclinical investigations on their use in lumbar vertebrae. This study compared the stress-strain distribution of normal and expandable pedicle screws, showing that the expandable screws had better fixation and stability.

Summary: This study proposes a new universal method using computed tomography (CT) morphological parameters analysis to assist precise pedicle screw placement in the subaxial cervical spine. Through the analysis of data from 53 participants, it was found that the six parameters were closely related to the patient's gender, height, and weight. Among them, pedicle height and width were linearly correlated and could guide the selection of appropriate screws. Additionally, changes in sagittal section angle were independent of cervical curvature or posture.

Summary: Patients with sandwich AAD have distinct clinical manifestations and are at greater risk for myelopathy. They also have higher incidences of lower cranial nerve palsy, Chiari malformation, and syringomyelia. Treatment for these patients often requires the use of various internal fixation techniques and transoral release procedures.

Summary: This study describes a new and safe technique for freehand cervical pedicle screw insertion using preoperative CT measurements as a guide and a medial pedicle pivot point. The results show that this technique allows for a safe and accurate procedure in patients with a pedicle diameter of 3.5 mm or greater.

Summary: This study compares the stability of lateral mass screws and cervical pedicle screws in the subaxial cervical spine. The biomechanical testing shows no significant difference in primary stability between the two techniques, but the mean load failure is slightly higher in the cervical pedicle screws group.

Summary: The present study assessed the feasibility, safety, and accuracy of navigated spinopelvic fixation with the use of high-resolution 3D intraoperative imaging and real-time spinal navigation. The results showed successful implantation of S1 screws in 53% and S2AIS in 85% of patients, indicating that navigation technology improved accuracy and reduced surgical time.
