Abstract
The study's aim is to calculate the parameters for retrograde insertion points for fixed superior pubic ramus fractures. From the pubic symphysis, diameter and length of the screw were measured, as well as the angle between the screw axis and the 3 planes. When the diameter was fixed at 4.5 mm, the maximum lengths were 125 mm and 119 mm. When the fracture occurs in Zone I, the penetration point could be selected in the pubic symphysis pubis angle to ensure that medial fracture fragments have sufficient screw channel length.
