Effect of different inner core diameters on structural strength of cannulated pedicle screws under various lumbar spine movements
BACKGROUND: Currently, cannulated pedicle screws have been widely used in minimal invasive or navigation techniques. However, the stress distribution and the strength of different core diameters of cannulated screw are not clear. This study aimed to investigate the mechanical strength of cannulated...
