Pelvic injuries are characterized by the fracture of one or more pelvic bones and can be classified using multiple systems. In particular, symphysis fractures categorized as rotationally unstable and vertically stable are classified as B1 fractures according to the Tile classification, and APC I and II according to the Young and Burgess classification. Open reduction and osteosynthesis, achieved through plate fixation of the pelvic ring, are the main techniques used in this case. In literature, various plate designs are documented, such as two-hole, multi-hole, and double plates. However, these methods may lead to implant loosening due to the excessive rigidity imposed on the pelvic ring.
