Okay no pictures forthcoming until I get home and my other half can resize them...
three types of pelvic fractures based on mechanism of injury (young and burgess classification)
lateral compression
anteroposterior compression
vertical shear
ap compression and vertical shear open the pelvic ring and have increased incidence of bleeding. Lateral compression doesn't seem to have the same sort of bleeding problems...probably because the venous plexus around the sacrum isn't disrupted. As for arterial bleeding pretty much all types can have fractures that shear across a vessel...we treat those with embolization rather than surgical intervention and obviously in the field that wouldn't be an option.
AP compression or open book type fractures may have benefit from a sheet wrapping/velcro device/ MAST trouser since they all help close back down the ring.
Vertical shear typically needs traction to bring the leg/pelvis back down to its normal orientation.
Pics will come later.
doc t.
Great responses above btw...lots of useful information.
