This study was presented problems with usage of transpedicular spine fixators.The purpose of this work was defined the value of pull-out strength of transpedicular screw from vertebrae. Impact of geometrical parameters of transpedicular screw on value of pull-out strength was analysed. Investigation was carried out on cadaver of lumbar and thoracic vertebrae. The results of investigation showed significance of geometrical parameters of transpedicular screws on durability of screw-vertebrae connection. This study proved also that very important for good performance of the vertebrae and pedicle screw unit is adequate match the screw diameter up with pedicle diameter.
