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.
This is the normal structure of the vertebrae in the body. However, in Anterolisthesis the upper vertebral body tends to slip forward and lies abnormally as compared to the second vertebral body. This phenomena of slipping forward of the upper vertebral body is known as the Anterolisthesis. It causes immense pain at the back.
