摘要
Study Design:Comparative biomechanical study by finite element (FE) method.Objective:To investigate the pullout strength of pedicle screws using different insertional trajectories.Summary of Background Data:Pedicle screw fixation has become the gold standard for spinal fusion, however, not much has
