Pelvic Injuries in Trauma

Pelvic Anatomy

1. Sacrum

2. Innominate bones

3. Ligamentous complex

Pelvic Anatomy

Pelvic # in approx. 9% of all major traumas

All age mortality rate = 5-to-16%

Age > 65 years mortality rate = 20%

Some mortality quotes up to 45% ?

Pelvic Fractures in Trauma

Age > 65 years mortality rate = 20%

What does this mean?

? isolated pelvic injury (without an abdominal injury)

Pelvic #s = increased risk of death

Pelvic Fractures in Trauma

Where can we bleed from?

Where can we bleed from?

1. Pelvic venous plexus

2. Pelvic arterial injury

3. Fracture bone surfaces

4. Any visceral injury

Remember: extra-pelvic injuries

How much blood can we lose into our pelvis ?

1 litre ?

2 litres ?

3 litres ?

4 litres ?

5 litres ?

How much blood can we lose into our pelvis ?

‘Haemorrhage from pelvic fracture is essentially bleeding into a free space, potentially capable of accommodating the patient’s entire blood volume without gaining sufficient pressure-dependent tamponade’

(Suzuki et al., 2008)

Mechanism of Injury and Classification

Three mechanisms

i. AP Compression Injury

ii. Lateral Compression Injury

iii. A Shear Force Injury

Mechanism of Injury and Classification

Three mechanisms four patterns



iii. A Shear Force Injury

iv. A Combination

How:

RTC (car vs. peadestrian / motor-cycle crash)

direct crush injury

fall (>12ft)


How:

RTC (car vs. peadestrian / motor-cycle crash)

direct crush injury

fall (>12ft)

What Happens:

symphysis pubis brakes

tearing of posterior ligamentous complex

(may rupture venous plexus / internal iliac artery)

AP Compression (‘open book pelvis’)Frequency = 15 to 20 %


How:

RTC (motor-cycle crash)

Direct compression / crush


How:

RTC (motor-cycle crash)

Direct compression / crush

What Happens:

internal rotation of hemi-pelvis

fractures around pubis

genitourinary system injury

(life threatening haemorrhage is less common)

Lateral Compression (‘closed pelvis’)Frequency = 60 to 70 %


How:

falling from a height onto one limb

RTC

iii. Shear Force Injury

How:

falling from a height onto one limb

RTC

What Happens:

high-energy applied in a vertical plane

major instability of pelvisVertical Shear

Frequency = 5 to 15%

iii. Shear Force Injury

Tile Classification

Young Classification

Ross Classification

iv. Combination

iv. Combinationi. AP Compression Injury

? major haemorrhage of the venous plexus / internal iliac artery

ii. Lateral Compression

injury to bladder/urethra/other / ↓ pelvic volume therefore ? ↓ haemorrhage

iii. A Shear Force

high-energy / major instability

Managing the Pelvis in the EDSheet

Pelvic binders / splints

? Bend knees & tie ankles (internal rotation)

Scoops (not boards)

Large IV lines / ?permissive hypotensive

resuscitation / ? haemorrhage protocol

Definitive Management of the Pelvis

Surgery stem bleeding / fix pelvis / pack pelvis

Angiography plus iatrogenic embolization

Conclusion

Assume there is not a isolated pelvic injury

Assume the worst

Early intervention / minimal pelvis movement once splinted

Thankyou
