Although clinically important, the lumbar epidural space is inconsistently described in textbooks of both anatomy and anaesthetics. This anatomical study of twelve cadavers was performed in an attempt to clarify the description of this region. ⋯ This contains the internal vertebral venous plexus and a posterior deposit of fat which lies in a recess between the ligamenta flava. These findings are discussed in relation to previous studies in an attempt to arrive at a cohesive description of the epidural region.
