A retrolisthesis is a posterior displacement of one vertebral body with respect to the adjacent vertebrae to a degree less than a luxation (dislocation) .igns and symptoms [edit]. Retrolisthesis may lead to symptoms of greatly varying intensity and distribution. This is because of the variable nature of the impact on nerve tissue and of the mechanical impact on the spinal joints themselves.
Retrograde spondylolisthesis, or retrolisthesis, is the condition or problem that results when one vertebra (spinal bone) slips backward in relation to the vertebra that is below it. This is a rather rare and unusual problem compared to the more common antegrade spondylolisthsis.ypically and traditionally the term spondylolisthesis by definition means the forward slippage of one vertebra in relation to the one below it, but the additional term antergrade is added to clarify the direction of abnormal movement because of the occasional occurrence of backward movement.
