Abstract
OBJECTIVES: The study's aim is to calculate the parameters for retrograde insertion points for fixed superior pubic ramus fractures. METHODS: 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. RESULTS: When the diameter was fixed at 4.5 mm, the maximum lengths were 125 mm and 119 mm. CONCLUSIONS: 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.
