Are fractures above and below the waist in a highway trauma victim an indicator of abdominal injury?

In a previous review of all highway trauma victims admitted to The Southern New Jersey Regional Trauma Center from 10/1/83 to 10/31/84, it was found that concomitant skeletal fractures above and below the waist (LUBI-lower and upper body injury) were accompanied by an extremely high rate of visceral injury to the head, chest, or abdomen The original hypothesis vas found to be questionable; however, by defining LUBI to consider only femur fractures as lower body fractures (FUBI). A useful indicator of occult abdominal injury in the highway trauma victim has been developed.
