A retrolisthesis is an acute, degenerative, or congenital condition in which a vertebra in the spine becomes displaced and moves backward. In most cases, retrolisthesis occurs when a soft disc that separates and cushions vertebrae either deteriorates or ruptures.
Anterolisthesis is the term for part of the vertebral body being  abnormally positioned compared to the vertebral body below it. This  is caused by the upper vertebrate slipâ¦ping on the lower one. The  slippage is rated 1-4 with 1 being the mild at about 20% slippage  and 4 being the worse at 100%.
