its pretty simple actually. normally we have what is called the 'lordodic curve' within our c spines. this is just a naturally occuring curve that helps to displace wieght much more evenly within the cervical vertebrae. in some people,such as myself,we have lost this natural curve and the vertebrae then tend to be a bit more 'stacked up" upon themselves so the wieght distribution is more right 'on' the column vs that more spread out type of wieght? it,in and of itself really is not a huge thing,but it can create a much higher risk for slippage of a disc,either forward or backwards just becasue of the way it sits. does that help?

this is a very very common finding in many peoples MRIs or x rays. it can be a congenital thing,meaning it is just that way from birth,or it can also be from some form of injury from your past,even in childhood. it doesn;t take much depending upon your age when it occurs. i think mine actually occured in the third grade with a fall off a roof. if you need more info,just hollar. marcia
