Fig. 7From: A parametric investigation on traditional and cortical bone trajectory screws for transpedicular fixationThe distribution of screw stresses of the different fixators along the bone-screw interfaces (Line AB). A Flexion. B Extension. C Bending. D Rotation. The terms “Head”, “Entry”, “Junction”, and “Tip” denoted screw head (i.e., screw hub), entry site of the screw into posterior element, interface between posterior element and cortical bone, and screw tip, respectivelyBack to article page
