The aim of this experimental was to compare the durability of the use of the study transpedicular screw supported by dowel or bone cement. In this experimental study which was performed on fresh frozen calf vertebrae, two groups were formed. 7 fresh frozen calf vertebrae were used in each group (n=7). A transpedicular screw supported by a dowel was placed to the left side of the vertebrae and a transpedicular screw supported by bone cement was placed to the right side. Then mechanical pulling force was applied to these groups. The force at which the pull out of the screw occurred and the expansion value up to the moment of pulling out were recorded. There was no fracture in any subject. There was no statistically significant difference between groups in terms of pulling out and expansion value (p = 0.58). There is no difference in durability between the uses of a transpedicular screw supported by a dowel or bone cement.
