title: Radiologic assessment of lumbar intervertebral instability and degenerative spondylolisthesis.
abstract: Despite many efforts, there is no clear and widely accepted definition of lumbar instability because there are no unquestionable and currently applicable clinical or radiologic criteria available for this entity. This article reviews the current concepts of lumbar instability and the different imaging modalities used to make the diagnosis as evident as possible.
