The RCPmi is connected to the cervical spinal dura mater
via the MDB through the PAOM (Hack et al, 1995; Rutten et al., 1997; Alix et al, 1999; Nash et al, 2005; Zumpano et al, 2006; Scali et al, 2015; Yuan etal, 2016) and the RCPma and OCI is connected to the cervical spinal dura mater
via the MDB through the posterior atlanto-axial membrane (PAAM) (Hack et al, 1995; Rutten et al.; Alix et al.; Nash et al.; Zumpano et al.; Scali et al., 2005; Yuan et al.).
Normally, the spinal dura mater
is loosely anchored to the vertebral canal by the nerve roots and the periosteum at the foramen magnum and the dorsal surfaces of C2 and C3 and the other at the coccyx.
Since the spinal cord is injured by being compressed with the intervertebral disc tissues in front of the spinal dura mater
and fractured bones, anterior decompression is more suitable for alleviating or eliminating spinal cord compression under direct vision.
They can occur in many atypical locations, ranging from the neck to the spinal dura mater
, to below the diaphragm.
(12) They noted the presence of connective tissue attaching the RCPmi fascia and the spinal dura mater in the posterior cranio-cervical region in adult human cadavers.
Investigation of connective tissue attachments to the cervical spinal dura mater. Clin Anat.
In the past 20 years, the findings confirm that the RCPmi is connected to the cervical spinal dura mater
via the MDB through the posterior antlanto-occipital interspace (Hack et al.; Scali et al., 2013; Pontell et al.; Su et al.; Zheng et al.).
Following the same idea, other authors point to the existence of a bridge of connective tissue between the RCPM muscle and dorsal spinal dura mater
in the occipitoatlantal junction (Hack et al, 1995; Torres, 2008).
