The contents of the anterior epidural cavity were studied to elucidate the relationship between veins, ligaments, and membranous formations. Anatomical, radiological and histological studies on human specimens after latex or gelatin/gadolinium venous injection at the level of the lumbar spine show that the posterior longitudinal ligament is a cross-shaped formation which includes the septum, the superficial part extending into the intervertebral foramen and the anterior ligaments of the dura mater. The anterior epidural cavity contains two medial and two lateral spaces. The two medial cavities enclose anterior and medial venous plexuses, which together receive the basivertebral veins; the two lateral cavities receive the anterior longitudinal veins. Contents of the medial and lateral cavities pass freely between the two. The lateral cavity connects with the intervertebral canal and dorsally into the posterior epidural space.
对硬膜外前腔的内容物进行了研究，以阐明静脉、韧带和膜性结构之间的关系。对腰椎水平经乳胶或明胶/钆静脉注射后的人体标本进行的解剖学、放射学和组织学研究表明，后纵韧带是一种十字形结构，包括隔膜、延伸至椎间孔的浅表部分以及硬脑膜的前韧带。硬膜外前腔包含两个内侧间隙和两个外侧间隙。两个内侧腔包绕前内侧静脉丛，它们共同收纳椎基底静脉；两个外侧腔收纳前纵静脉。内侧腔和外侧腔的内容物可在两者之间自由通过。外侧腔与椎间管相连，并在背侧通向硬膜外后间隙。
