“…It is firmly attached at the foramen magnum cranially and to the coccygeal vertebrae caudally. Laterally, it extends over and blends with the nerve roots epineurium [28] . Within the spinal canal, the dura is only loosely attached to the posterior longitudinal ligaments and is therefore free to move considerably during spinal movements.…”

We report the case of an 18-year old male with a history of asymmetric weakness and amyotrophy of distal upper extremities, suggestive of Hirayama disease. Magnetic resonance imaging (MRI) of the cervical spine was obtained both in flexion and neutral position. Flexion MRI showed forward displacement of the dura and subsequent cord compression, with associated marked enlargement and postcontrast enhancement of posterior epidural plexus. These findings are pathognomonic of the disorder. On neutral MRI abnormalities may be subtle: in our case, they included loss of physiological lordosis, asymmetric atrophy and increased T2 signal intensity of the lower anterior cervical cord. The ability to identify abnormalities on neutral MRI however is even more important in that it allows the radiologist to include a flexion sequence in the MRI examination, if not specifically requested by the referring physician, and in cases in which the suspicion of the disorder has not been raised.

“…Most notably, the cervical spine increases in length approximately 3 cm during neck flexion. Consequently the dura, attached above and below, migrates within the spinal canal, compensating for the increased length of the cervical canal in flexion [28 , 29] .…”

“…The cord is encased by the pia mater, the innermost layer of the spinal meninges. It is often considered as a single membrane with the intermediary arachnoid mater; collectively known as the leptomeninges (Figure 1b; Kayalioglu, 2009a). This continues to envelop the spinal roots as they leave the spinal cord, finally blending with the perineum of the spinal nerves.…”

The human spinal cord can be described using a range of nomenclatures with each providing insight into its structure and function. Here we have comprehensively reviewed the key literature detailing the general structure, configuration of tracts, the cytoarchitecture of Rexed's laminae, and the neurochemistry at the spinal segmental level. The purpose of this review is to detail current anatomical understanding of how the spinal cord is structured and to aid researchers in identifying gaps in the literature that need to be studied to improve our knowledge of the spinal cord which in turn will improve the potential of therapeutic intervention for disorders of the spinal cord.

“…The outer layer also referred to as pachymeninges or the dura mater, is the toughest, thick, dense, and white fibrous (inextensible) connective tissue. The dura is composed of fibroblast and dense interlacing bundles of collagen and elastic fibers [17]. The elastic fibers provide considerable flexibility upon stretching during movements, and the collagen provides tensile strength and pro- [18,19].…”

Reinvestigation on Newer Facts to Anticipate, Avoid And Mitigate The Development of Post-Dural Puncture Headache-A Prospective Cohort Study

Purpose: Various researchers have described the size and the type of spinal needle used for neuraxial anesthesia as the most common risk factor for developing postdural puncture headache (PDPH). Even though the occurrence of the PDPH is rare in modern anesthesia practice, we come across many such patients despite following all guidelines or precautions. Patient-related factors for developing PDPH are relatively understudied. For that, clinical features commonly present in such patients may require a thorough investigation. Methods: This prospective cohort study included fifty patients admitted for lower extremities orthopedic surgeries and developed PDPH following the neuraxial blockade. We screened all patients in this study for the presence or absence of common manifestations suggestive of connective tissue disorders (CTD). The other outcomes, like the effect of spinal needle size/type to develop PDPH and time to develop PDPH, were also measured. Results: Almost all PDPH patients included in this study had common features suggestive of CTD: the ligamentous laxity (96%), high-arched palate (96%), the blue sclera (45%), joint hyperextensibility (82%), and ejection clicks (64%). PDPH occurred more frequently with the 25G spinal needle of Quincke type than 27G of Whitacre type (82% vs. 18%). The mean (SD) headache freedom time was 73.14 (24.74) hours. Conclusions: The CTD might also be a causative factor responsible for the development of PDPH in some individuals. It can be considered a risk factor to anticipate, avoid, and mitigate the development of PDPH.
