Management of Polytrauma with Multiple Right Lower Extremity Fractures
This polytrauma patient requires immediate hemodynamic assessment and stabilization, with the pelvic (iliac) fracture taking priority as it poses the greatest risk for life-threatening hemorrhage, followed by staged orthopedic fixation of the femur, tibial plateau, and fibula fractures based on the patient's physiologic status. 1
Initial Assessment and Resuscitation
Hemodynamic Status Determination
- Classify the patient as hemodynamically stable or unstable using ATLS criteria: blood pressure <90 mmHg, heart rate >120 bpm, evidence of skin vasoconstriction (cool, clammy skin, decreased capillary refill), altered consciousness, or shortness of breath 1
- Measure serum lactate and base deficit as sensitive markers to estimate traumatic-hemorrhagic shock extent and monitor resuscitation response 1
- Obtain pelvic X-ray and E-FAST in the Emergency Department to identify injuries requiring early stabilization, angiography, or laparotomy 1
Immediate Pelvic Stabilization
- Apply pelvic binder immediately if hemodynamic instability is present or suspected from pelvic fracture mechanism 1
- Time between Emergency Department arrival and definitive bleeding control should be minimized and must not exceed 60 minutes 1
Management Based on Hemodynamic Status
If Hemodynamically UNSTABLE
Pelvic Fracture Management:
- Proceed immediately with external pelvic fixation (provides rigid temporary stability and serves as adjunct to hemorrhage control) 1
- Perform preperitoneal pelvic packing (PPP) via separate suprapubic midline incision, placing three laparotomy pads on each side of the bladder in the retroperitoneal space below the pelvic brim 1
- External fixation is required as adjunct to PPP to provide stable counterpressure for effective packing 1
- Consider angiographic embolization if ongoing hemorrhage or transfusion requirements persist after PPP (needed in 13-20% of cases) 1
- For embolization: perform non-selective bilateral internal iliac artery embolization in unstable patients with multiple bleeding targets 1
- Arterial access via common femoral arteries is preferred; use humeral route if pelvic injuries prevent femoral access 2
- PPP revision should occur within 48-72 hours 1
Other Fractures:
- Delay definitive fixation of femur, tibial plateau, and fibula fractures until successful resuscitation is achieved 1
- Patients "in extremis" with coagulopathy must be resuscitated prior to definitive orthopedic fixation to avoid the lethal triad of coagulopathy, acidosis, and hypothermia 1
If Hemodynamically STABLE
Pelvic Fracture Management:
- Determine mechanical stability of the pelvic ring based on fracture pattern 1
- If mechanically unstable (rotationally or vertically unstable patterns): proceed with early definitive internal fixation within 24 hours if patient is stable or "borderline" 1
- Surgical fixation modalities include iliosacral screw fixation, pubic symphysis plating (if diastasis >2.5 cm), or spinopelvic fixation for vertically unstable patterns 1
- If mechanically stable with negative CT scan: can proceed directly to definitive stabilization 1
Femoral Shaft Fracture:
- Perform early definitive fixation within 24 hours in hemodynamically stable patients to reduce complications and improve outcomes 1
- Intramedullary nailing is the standard treatment for midshaft femur fractures in polytrauma patients
- Early stabilization decreases incidence of multiple organ failure and mortality 1
Tibial Plateau Fracture:
- Surgical reduction and stabilization is indicated for displaced tibial plateau fractures to restore articular congruity, mechanical alignment, and ligamentous stability 3, 4
- Timing of surgery and soft-tissue handling are critical to treatment success 3
- Goal is stable, well-aligned, congruent joint with early range of motion 3
- Techniques include open reduction with internal fixation, bone grafting for depressed fragments, and buttress plating 3, 5
- Consider arthroscopic-assisted reduction for appropriate fracture patterns 5
Proximal Fibula Fracture:
- Generally treated non-operatively unless associated with significant tibial plateau instability
- The fibula fracture is typically addressed in conjunction with tibial plateau fixation if surgical intervention is required
Timing Considerations for Definitive Fixation
Physiologically Stable/"Borderline" Patients:
- Perform early definitive fixation within 24 hours for all fractures 1
- Multiple studies demonstrate that early fixation in stable patients reduces complications and improves outcomes 1
Physiologically Deranged Polytrauma Patients:
- Postpone definitive pelvic fixation until after day 4 post-injury 1
- Complication rates significantly increase when definitive fixation performed between days 2-4 1
- Complication rates decrease when surgery delayed to days 6-8 post-injury 1
- Use damage control external fixation initially, then convert to definitive internal fixation after successful resuscitation 1
Critical Pitfalls to Avoid
- Never attempt early definitive pelvic fixation in patients with ongoing hemorrhagic shock - this significantly increases mortality risk from exsanguination 1
- Do not delay hemorrhage control beyond 60 minutes - mortality increases 1% for every 3 minutes of delay 1
- Avoid fixation between days 2-4 in unstable polytrauma patients - this window has highest complication rates 1
- Ensure adequate soft-tissue assessment before tibial plateau surgery - timing and soft-tissue handling are critical to success 3
- Monitor for urethral injury in pelvic fractures (blood at meatus is contraindication to catheterization without retrograde urethrography) 6
Expected Outcomes
- With appropriate management, 87% of tibial plateau fractures achieve successful outcomes, though severely comminuted fractures (AO Type C3) have poorer prognosis 5
- Early pelvic stabilization decreases multiple organ failure incidence and mortality 1
- At least half of tibial plateau patients return to original physical activity level when anatomy and stability are restored 4
- Complications include post-traumatic arthritis, infection (especially in severe injuries), chronic pain, and functional limitations 1, 4
