Tricortical screw spinal fixation: a scoping review and introduction of technique, biomechanical advantages, and clinical outcomes in high-risk vertebral fractures

TCPS fixation enhances spinal stabilization in high-risk fractures through tri-cortical load distribution, minimizing screw loosening and invasiveness. While requiring precise trajectory planning to avoid perforation risks, it offers shorter operative times, reduced blood loss, and improved biomechanical stability, particularly in osteoporotic/DISH patients. Further prospective studies are needed to optimize patient selection and refine navigation-assisted techniques for broader applicability.
