Taxonomic definition
Taxonomic definition The subdural space is a space of compartment of head [spatium compartimenti capitis ] which is a occasional space that can be opened by the separation of the arachnoid [arachnoidea ] from the dura mater [pachymeninx ] as the result a pathologic process.
Although the terms Spatium subdurale and Spatium epidurale/extradurale are in common usage, under normal conditions the arachnoid is attached to the dura and the dura is attached to the skull; there are no naturally occurring spaces at these interfaces at all. The occurrence of these spaces is the result of trauma or of pathological process that artifactually separates the arachnoid from the dura or the dura from the skull (Haines DE 1991 On the question of a subdural space. Anat Rec 230:3-21; Van Denabeele F, Creemans J, Lambrichts I 1996 Ultrastructure of the human spinal arachnoid mater and dura mater. J Anat (Lond) 189:417-430).
