ABSTRACT
Over recent years,pedicle screw fixation is widely used in spine surgery,which allows 3-dimensional fixation with a more rigidconstruct and permits a shorter fusion length.However,its fixationeffect is not so good for patients with severe osteoporosis.Cortical bone trajectory screw insertion has been advocated because it is reportedly less invasive,improvesscrew-bone purchase and reduces neurovascular injury.Based on the present evidence,the author evaluates the relative advantages of cortical bone channels.To this end,a search of relevant published studies reporting biomechanical,morphemetricor clinical outcomes after using of cortical bone trajectory screws in patients with spinal pathologies is reviewed.
