Abstract

Background and purpose: The inner pedicle diameter is very important in pedicle screw placement in order to achieve safe and strong posterior stabilization. The optimal pull-out strength can be achieved by a screw which fits into the pedicle medulla. The aim of the present study was to compare the inner and outer pedicle diameters of lumbar pedicles, to determine the inner/outer pedicle diameter ratios, and to develop a simple measure for estimating optimal pedicular screw size.
