High Energy Pelvic Fractures
• Occur in 10-20% of polytrauma victims
• Mortality varies with associated injuries
• Age, ISS and severe haemorrhage are best predictors of mortality

Polytrauma Mortality
• Pelvic-related mortality ~ 7-18%
• Pelvic # + intracranial mass (a) ~ 50%
+ intra-peritoneal injury (b) ~ 50%
+ (a) + (b) > 90%
• Pelvic # + thoracic / urological / musculoskeletal
~ 20%

Pelvic - related Mortality
• Mostly due to bleeding
• Bleeding may occur from venous or arterial injury or from the cancellous bone surfaces
• Different sources of bleeding require different interventions

• Transient responseto : - resuscitation
- external fixation- embolisation- Novo 7
• No response to laparotomy

Pelvic – related mortality
• The key is to differentiate transient and non-responders
• Clinical - unstable fractures- open fractures
• X-ray - unstable fractures- evidence of pelvic floor disruption- fractures extending into sciatic notch
• ? Physiological response to resuscitation

Assessment
A pelvic fracture:
• should be suspected from the history
• may not be clinically obvious
• confirmed by plain radiographs of the pelvis.
In addition to plain anteroposterior films two 45-degree oblique films should be obtained, the pelvic inlet and the pelvic outlet view.

Examination
• Instability can be assessed by compressing the ASIS, pulling on the leg and looking for evidence of damage to posterior structures (bruising or localised tenderness).

Options to try and control haemorrhage include:
• Mechanical stabilization
• Angiography / embolisation
• Pelvic packing
