The topography of the developing epidural ligaments in man was investigated by dissecting 12 fetuses ranging from 60-310 mm in CR length. It was found that in a 60 mm CR length fetus, the epidural space is occupied by an ubiquitous connective tissue which in longer fetuses becomes reduced into topographical structures. Posterior, lateral and anterior ligaments could be identified. The atlantodural and the sacral ligaments appear to be permanent ligaments anchoring the dural sac, whereas most of the dorsal ligaments become resorbed during the development of the fetus. These ligaments may be responsible for the compression of the nerve root that occurs when the dural sleeve and the contained nerve root are stretched over a protrusion (e.g. a protruded disc).
通过解剖12例颅顶-臀长在60-310毫米之间的胎儿，研究了人类发育过程中硬膜外韧带的形态。研究发现，在颅顶-臀长为60毫米的胎儿中，硬膜外间隙被一种普遍存在的结缔组织占据，而在较大的胎儿中，这种结缔组织会逐渐演变成不同部位的结构。可以识别出后韧带、侧韧带和前韧带。寰枕韧带和骶韧带似乎是固定硬脊膜囊的永久性韧带，而大多数背侧韧带在胎儿发育过程中会被吸收。当硬脊膜袖套及其包含的神经根在突出物（如突出的椎间盘）上伸展时，这些韧带可能是导致神经根受压的原因。
