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.
What this means is that in this study only people with a retrolisthesis had a bulging disc. No retrolisthesis - no disc bulge. This was present in those with a bulged disc 100% of the time. The specificity medically means: The extent to which a particular diagnostic test is specific for a given condition.
