Pelvic fractures associated with high-energy trauma and polytrauma
Hemorrhage is a major cause of early mortality in unstable pelvic ring injuries
Older adult trends
Low-energy pubic rami fractures increasing with aging population
Osteoporosis and falls as key drivers
Pathophysiology
Bleeding sources
Venous plexus bleeding predominant in many pelvic ring injuries
Cancellous bone bleeding contributes significantly
Arterial injury subset
Internal iliac branch injury possible
CT arterial extravasation marker
Instability and volume
Pelvic ring disruption increases pelvic volume
Increased volume reduces tamponade effect
External compression reduces volume and displacement
Neurologic injury mechanisms
Lumbosacral plexus stretch or compression with posterior ring disruption
Sacral fracture canal involvement risk
Therapeutic Considerations
Pelvic binder evidence and guidance
Early non-invasive pelvic compression recommended in unstable pelvic fractures WSES Grade 1A
Pelvic binders superior to sheet wrapping for hemorrhage control WSES Grade 1C
Pelvic orthotic device reduces displacement and pelvic volume EAST Level 3
Binder may not reliably reduce blood loss across heterogeneous clinical studies
Imaging guidance
Avoid log rolling before pelvic imaging in suspected pelvic fracture except specific emergent indications per NICE
Hemorrhage control strategy rationale
Packing targets venous and bony bleeding
Angioembolization targets arterial bleeding
External fixation improves mechanical stability and supports tamponade
Patient Discharge Instructions
copy discharge instructions
Discharge instructions
Weight bearing
Non weight bearing or partial weight bearing per orthopedics plan
Crutches or walker use instruction
Pain control
Acetaminophen scheduled option if no contraindication
NSAID option if no contraindication and not late pregnancy
Opioid limited use for breakthrough pain with constipation prevention plan
Activity and swelling
Avoid strenuous activity and heavy lifting until cleared
Ice and rest strategy in first 48 hours if helpful
Return precautions
Worsening pain uncontrolled by medications
New numbness or weakness in either leg
Cold or pale foot
New inability to urinate
Blood at urethral opening
Fever or wound drainage if open injury
Dizziness syncope or chest pain
Follow-up
Orthopedics follow-up timing provided
Repeat imaging plan if advised
Physical therapy plan if advised
