Axial pullout testing is the standard pre-clinical testing method for new screw designs although it has questioned clinical relevance. The aim of this study was to determine the fixation strength of three current osteoporotic fixation techniques and to investigate whether or not pullout testing results can directly relate to those of the more physiologic fatigue testing.en0940-6719European spine journal20141021962202SpringerCement augmentationFatiguePedicle screwPulloutSpineToggleMedicine, HealthEngineeringInfluence of the screw augmentation technique and a diameter increase on pedicle screw fixation in the osteoporotic spine : pullout versus fatigue testingJournal Article10.1007/s00586-014-3476-7Other
