In clinical routine, the application of radiofrequencywarmed bone cement through a cannulated pedicle screw would signify a major improvement because the rate of cement extravasations can be markedly reduced and pullout forces increased. Furthermore, the procedure is associated with less radiation exposure for the surgeon because cement augmentation can be performed mechanically at a safe distance from the source of radiation. Finally, the patient also benefits from the reduced risk of cement extravasation and the possibility of minimally invasive insertion of screws and cement augmentation.
