Acute Complications of Open Book Open Pelvic Fractures

Primary Life-Threatening Concerns

Open book pelvic fractures with open wounds carry mortality rates exceeding 50%, with exsanguinating hemorrhage and perineal contamination representing the two immediate threats to survival, as stated by the American Society of Anesthesiologists 1, 2

Bleeding originates from multiple sources including disrupted pelvic venous plexus from the expanded pelvic ring, as reported by the American College of Surgeons 1
Bone bleeding from fracture surfaces is a common cause of hemorrhage, according to the American Association for the Surgery of Trauma 1
Hemodynamic instability occurs frequently and requires immediate mechanical stabilization to limit hematoma expansion, as recommended by the Eastern Association for the Surgery of Trauma 1, 3

Pelvic sepsis is the second leading cause of mortality after hemorrhage control is achieved, as stated by the Infectious Diseases Society of America 1, 2
Perineal contamination from open wounds creates high risk for deep pelvic infections, particularly when fecal contamination occurs, according to the American Urological Association 1, 2
Infection risk increases significantly without early antibiotic administration within 3 hours, as recommended by the Society of Critical Care Medicine 2

Bladder injuries occur in 4-15% of unstable pelvic fractures, particularly intraperitoneal ruptures that require early surgical closure, as reported by the American Urological Association 4
Posterior urethral injuries are present in 4-19% of pelvic fractures, especially with bilateral pubic rami fractures and sacroiliac dislocation, according to the American Association for the Surgery of Trauma 4

Mechanical stabilization with pelvic binder application immediately upon recognition is crucial, as recommended by the Eastern Association for the Surgery of Trauma 3
Hemorrhage control via external fixation should not exceed 60 minutes from hospital admission, as stated by the American College of Surgeons 1, 3, 4
Angioembolization should be performed if bleeding persists after mechanical stabilization, ideally within 60 minutes, according to the Society of Interventional Radiology 3, 4
Antibiotic administration within 3 hours is essential, as recommended by the Infectious Diseases Society of America 2

Definitive wound coverage must occur within 7 days to reduce fracture-related infection risk, as stated by the American College of Surgeons 2

Delaying colostomy in patients with buttock or perineal wounds is associated with near-universal pelvic sepsis, as reported by the American Society of Colon and Rectal Surgeons 4
Exceeding 60 minutes from admission to bleeding control intervention increases mortality, as stated by the American Heart Association 3, 4
Delaying antibiotic administration beyond 3 hours increases infection risk exponentially, as recommended by the Infectious Diseases Society of America 2
Extending antibiotics beyond 72 hours without documented infection is not recommended, as stated by the American Society of Health-System Pharmacists 2
Missing associated rectal injuries can have severe consequences, and sigmoidoscopy should be performed in all open pelvic fractures, according to the American College of Surgeons 1

Functional consequences are typically severe despite survival, as reported by the American Academy of Orthopaedic Surgeons 1
