Basically, the higher is the grade, serious is the problem. Grade I: It is treated as the low intensity Anterolisthesis in the human body. The slipping forward percentage of the body remains preciously less than 25%. Grade II: The slippage percentage of the vertebral body in this situation remains between 25%-50%.
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.
