  1. Pelvic fracture Management Erik Hasenboehler MD Orthopaedic Trauma Surgery Baltimore MD Kentucky Trauma Symposium 2012

  2. Subjects Basic Polytrauma management Polytrauma basic science Pelvis Exam, Stability and managment Acute treatment of pelvic ring injuries Open Pelvis fracture

  3. Pelvicfracture and Polytrauma Management One goal !!!!!!! Save the patient`s life !

  4. ATLS: Structured Trauma Care Hemodynamically Unstable Pelvic Fracture Management by Advanced Trauma Life Support Guidelines Results in High Mortality . Orthopedics 2012 Stahel PF, Smith WR, Moore EE. Current trends in resuscitation strategy for the multiply injured patient. Injury. 2009 Phases of Management Primary Survey Resuscitation Secondary Survey Definitive Care Tertiary Survey Airway Breathing Circulation Disability Exposure

  5. Steps of Acute Management • Assess • Physical Exam • Labs, Physiology • Images • Stabilize • Resuscitate • Contain • Sheet/Ex fix/C-clamp Damage control orthopaedics in unstable pelvic ring injuries. P.V. Giannoudis and H.C. Pape, Injury 2004

  6. Basic Science of Trauma Second hit phenomenon: Existing evidence of clinical implications Lasanianos et al Injury 2012 • First Hit • Primary injury response • Second Hit • Incomplete resuscitation • Hemorrhage • Prolonged surgery Systemic Inflammatory Synergistic Inflammatory

  7. Two Hit Model MOF Severe SIRS Delayed definitive surgery First insult Moderate SIRS Moderate immuno-suppression 2nd insult Severe immunosuppression Definitive surgery EARLY Infection MOF Moore FA and Moore EE. SurgClin North Am. 1995

  8. Secondary Period Damage control orthopaedics in unstable pelvic ring injuries. P.V. Giannoudis and H.C. Pape, Injury 2004 Damage control orthopedics: current evidence Lichtea et al CO-Critical Care 2012 Second hit phenomenon: Existing evidence of clinical implications . Lasanianos et al. Injury 2011 • Old concept: Day 1, 5-7 (window of opportunity) and after 14 days • Patients operated on day 2-4vs day 5-8 worse inflammatory changes • Avoid significant surgery on days 2-4 for patients at risk • For more severely injured patients a longer waiting period may be needed

  9. Pre- Hospital: Devastating injury

  10. Hospital-Acute/Primary: shock, hypoxia or head injury

  11. Hospital-Secondary/Tertiary: MOF or ARDS

  12. Measurable Risk Factors • Damage control orthopedics: current evidence, Lichte et al CO-Critical Care 2012 • Keel M, Trentz O. Pathophysiology of polytrauma. Injury 2005 • Giannoudis PV. Current concepts of the inflammatory response after major trauma: an update. Injury 2003 • Tschoeke SK, et al. The early second hit in trauma management augments the proinflammatory immune response to multiple injuries. J Trauma 2007 • HD unstable or difficult resuscitation • Under resuscitation • Shock and > 25 units PRBC’s • Thrombocytopenia ( platelets < 90,000) • Hypothermia (< 32° C) • Bilateral lung contusions on initial x-ray • Multiple long bone fractures and truncal AIS >2 • Presumed OR time > 6 hours • Exaggerated inflammatory response (IL-6> 800 pg/ml)

  13. Causes of Death from Pelvis Fractures < 24 hours: blood loss > 24 hours: MOF Exsanguination caused 75% of the deaths

  14. Orthopaedic Damage Control “… temporary stabilization of fractures soon after injury, minimizing the operative time, and preventing heat and blood loss.” • In severely injured patients, initial orthopaedic surgery should not be definitive treatment • Definitive treatment delayed until after patients overall physiology improves Damage control orthopedics: current evidence, Lichte et al CO-Critical Care 2012

  15. Damage Control

  16. Minimize the Second Hit

  17. Assess • Treatment of pelvic ring injuries is usually amultidisciplinaryactivity • Trauma, Orthopaedics, Radiology • Urology/Gynecology

  18. Lots to bleed Big space to bleed into

  19. Volume Changes in the True Pelvis During Disruption of the Pelvic Ring – Where does it go? Moss and Bircher, 1996 Effects of Pelvic Volume Changes on Retroperitoneal and Intra- Abdominal Pressure in the Injured Pelvic Ring: A Cadaveric Model Köher et al 2011 Volume increase - r3 Volume increase 1 – 2L

  20. Physical Exam OBTAIN INFORMATION FIRST • Perform a FULL physical exam • Evaluate lower extremities position Shortening/Rotation • Skin Ecchymosis • Open wound Around the pelvis • !!!!Be alert for open pelvic fractures!!! • Neurovascular exam

  21. Physical Exam Palpate anterior pelvis Watch for perineal Lacerations Scrotal/Labial Swelling Flank Ecchymosis

  22. Physical Exam • Turn the patient!

  23. Physical Exam • Morel-Lavalle lesions • Degloving of the flank, thigh • Large dead space • Increased incidence of infection

  24. #2: Is the Injury Pattern “Stable” or “Unstable”?

  25. Rotational Stability AP Compression Lateral Compression One Positive Exam Only! Gonzalez RP, Fried PQ, Bukhalo M. The utility of clinical examination in screening for pelvic fractures in blunt trauma. J Am Coll Surg. 2002.

  26. Physical Exam Abnormal position of the lower extremity

  27. Pelvis “Stability” • ALWAYS a combination of x-rays and a clinical exam • A single x-ray is a static view • May have been way more displaced at the time of injury

  28. Imaging- AP pelvis Part of ATLS Shows obvious, grossly unstable injuries Obtain Inlet Outlet views In an HD unstable patient DO NOT get more films

  29. Vertical Stability Push pull on leg while palpating the ASIS

  30. CT Scans Blush= embolizable arterial injury!

  31. “Stabilizing” Theories Decreases pelvic volume Prevents gross motion, clot disruption Reduces cancellous bony bleeding

  32. Why is Stability Important? APC 2, 3; LC 3; VS LC3 APC2,3 VS

  33. Mortality Rate LCIII- 14% VS - 25% APC II- 25% APC III- 37% • Magnussen et al. Predicting blood loss in isolated pelvic and acetabular high- energy trauma. J Orthop Trauma. 2007 • Smith W, Williams A, Agudelo J, et al. Early predictors of mortality in hemodynamically unstable pelvis fractures. J Orthop Trauma. 2007;

  34. Transfusion Requirements Lateral Compression - 3.6 Combined Mechanical- 8.5 Vertical Shear - 9.2 AP Compression - 14.8 Hemorrhage occurs up to 75% of patients with high energy injuries • Magnussen et al. Predicting blood loss in isolated pelvic and acetabular high- energy trauma. J Orthop Trauma. 2007 • Smith W, Williams A, Agudelo J, et al.

  35. WHAT TO USE TO STABILIZE THE PELVIS

  36. MAST / PASG

  37. Sheet or Binder

  38. Pelvic Binder Easily applied during resuscitation Portable

  39. Acute Management SAM Sling / T-POD / Circumferential Sheet: TOO HIGH!! Greater Trochanter!! Pelvis and Acetabulum Frontline Treatment

  40. Pelvic Sheeting Correct Incorrect Routt et all JOT 2002

  41. Traction Alone or in combination with sheet/ binder/ ex fix Particularly useful for vertical shear injuries Prevents vertical migration

  42. Anterior External Fixation Disadvantages Can cause a different deformity Poor control of posterior pelvic ring Pin tract infections It’s not that easy

  43. Pelvic C-Clamp Ganz R, et al. The antishock pelvic clamp. ClinOrthopRelat Res. 1991.

  44. AIRS: I agree that the incidence of arterial bleeding after high energy pelvic trauma is 10% • Yes • No- I think it is higher

  45. Who should get angiography? Rationale: fracture (cancellous) / venous > 90% arterial < 10%

  46. Who should get angiography? Rationale: fracture (cancellous) / venous > 90% arterial < 10%
