the initial injury results in a disruption of neurons and protective layers which happens at the
moment of impact. The sec- ondary injury the occurs when the inflammatory response causes
further damage, the patient may have hypo perfusion from systemic or local hemorrhage, or the
stress response causes vasoconstriction and leads to further blood flow reduction to the spinal
cord.



blood is ultimately shunted away from the cord due to decreased perfusion and inflammation
that can lead to compression of the cord
