When a tear in the outer, fibrous ring of an intervertebral disc allows the soft, central portion to bulge out beyond the damaged outer rings, the disc is said to be herniated. Disc herniation is frequently associated with age-related degeneration of the outer ring, known as the annulus fibrosus , but is normally triggered by trauma or ...
Spinal disc protrusion visible in MRI [1] A disc protrusion is a medical condition that can occur in some vertebrates, including humans, in which the outermost layers of the anulus fibrosus of the intervertebral discs of the spine are intact but bulge when one or more of the discs are under pressure.
55% of facet syndrome cases occur in cervical vertebrae, and 31% in lumbar. Spinal osteoarthritis is known as spondylosis . [ 7 ] Pathology of the C1-C2 (atlantoaxial) joint, the most mobile of all vertebral segments, accounts for 4% of all spondylosis .
An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column.Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
A cerebrospinal fluid leak (CSF leak or CSFL) is a medical condition where the cerebrospinal fluid (CSF) that surrounds the brain and spinal cord leaks out of one or more holes or tears in the dura mater. [1]
[28] [29] This inflammatory molecule, called tumor necrosis factor-alpha (TNF), is released not only by the herniated or protruding disc, but also in cases of disc tear (annular tear), by facet joints, and in spinal stenosis. [24] [30] [31] [32] In addition to causing pain and inflammation, TNF may also contribute to disc degeneration. [33]

The part of the spinal cord that was damaged corresponds to the spinal nerves at that level and below. Injuries can be cervical 1–8 (C1–C8), thoracic 1–12 (T1–T12), lumbar 1–5 (L1–L5), [9] or sacral (S1–S5). [10] A person's level of injury is defined as the lowest level of full sensation and function.
