Immediate stabilization of pedicle screws [PDF]
Current Directions in Biomedical Engineering, 2023 Abstract This study was designed as proof of principle and safety test of the novel technique, the Immediate Stabilization System (ISS). The technique is designed to immediately stabilize polymer-augmented pedicle screws (PAS) in deficient bone and avoid complications of loosening pedicle screws at the bone-screw interface, especially in
