Figure 2From: Axial pullout strength comparison of different screw designs: fenestrated screw, dual outer diameter screw and standard pedicle screwLateral (A) and posterior radiographs (B) of one of the specimens showing the screw placement and the injected cement spread through the bone. Placement of screws in straight fashion prevented the screws from coming in contact with each other, which could otherwise compromise the pullout strength.Back to article page
