IntroductionCement augmentation is a commonly performed procedure by spine surgeons as well as interventional radiologists. The ultimate goal of cement augmentation is to aid a vertebral body in resisting axial stresses. Understanding the difference between traditional and modern techniques in cement augmentation is therefore important in providing the best possible augmentation technique. Objective: To compare the traditional technique of using a cannulated needle to introduce cement followed by a non-cannulated, non-fenestrated screw against introduction of cement through a cannulated, fenestrated screw. Materials and Methods: Eight cadaveric spines were used. The T8-L1 vertebrae were dissected, divided into their respective groups, potted in a resin, augmented and subjected to increasing axial loading.
