Bones & Joints
Open book pelvic fractures are severe, life-threatening pelvic ring injuries where external rotation forces cause the pelvis to 'open like a book'—disrupting the pubic symphysis (front of pelvis) and often the sacroiliac joints or sacrum (back of pelvis), classified as APC-II or APC-III (Anterior-Posterior Compression) injuries in the Young-Burgess classification. These high-energy injuries typically result from motor vehicle accidents, pedestrian vs car collisions, or motorcycle crashes, presenting with massive pelvic instability and life-threatening hemorrhage from torn pelvic venous plexus and arterial bleeding (mortality 10-20% in severe cases despite modern trauma care). Immediate management focuses on hemorrhage control using pelvic binder application, resuscitation, and emergency pelvic stabilization (external fixator or emergent ORIF), followed by definitive surgical fixation once patient stabilized. These injuries often occur as part of polytrauma (multiple injuries) and require multidisciplinary trauma team management in specialized trauma centers, with long-term outcomes depending on associated injuries (bladder/urethral trauma, nerve injuries, blood loss) and quality of pelvic reduction and fixation.
