Surgeons need to be more cautious when assessing screw loosening based on radiological examination, since a considerable fraction of low extraction torque screws might have been underestimated. Furthermore, to our knowledge, for the first time we used extraction torque during screw removal surgery to analyze risk factors for screw loosening, our findings demonstrated that screws in non-fusion spine and fractured vertebrae had significantly lower extraction torque, while BMD and age showed low, but significant linear correlation with extraction torque. If such findings are detected, a second operation for revision should be considered as soon as possible to prevent potentially fatal complications. An in vitro study.
