A compound elevated skull fracture is a rare type of skull fracture where the fractured bone is elevated above the intact outer table of the skull. This type of skull fracture is always compound in nature.
With lateral skull fracture, the middle meningeal artery can be torn producing an epidural hematoma. With violent falls, traumatic subarachnoid hemorrhages due to arterial tears. During the fall, if the brain is thrust against the boney skull, it can be injured producing a small hemorrhage. A second mechanism, the bridging veins between the dura and the brain are torn producing a subdural hematoma.
