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 a form of spondylolithesis that described the manner of slippage of the vertebra. Anterolisthesis is the condition of the spine that involves the vertebrae. The vertebrae make up the spine and are bones that form an opening to allow a passageway for the spinal cord.
