  • Title: A radiographic simulation study of fixed superior pubic ramus fractures with retrograde screw insertion.
    Author: Quan Q, Hong L, Chang B, Liu RX, Zhang YQ, Zhao Q, Lu SB.
    Journal: J Orthop; 2016 Dec; 13(4):364-8. PubMed ID: 27504056.
    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.
