The Posterior Epidural Ligaments: A Cadaveric and Histological Investigation in the Lumbar Region
Figure 3
Comparative images of control ligamentum flavum and the identified posterior epidural ligament stained with H&E and EVG. Ligamentum flavum is 80% elastin and 20% collagen. Dura mater is a dense collagenous connective structure. On elastic van Gieson staining, elastin appears dark blue and collagen pink (H&E 40, EVG 40).
