Cervical spinal stenosis is one of the most common forms of spinal stenosis, along with lumbar spinal stenosis (which occurs at the level of the lower back instead of the neck). Thoracic spinal stenosis, at the level of the mid-back, is much less common. [2] Cervical spinal stenosis can be far more dangerous by compressing the spinal cord.
Moderate to severe spinal stenosis at the levels of L3/4 and L4/5 [further explanation needed] The diagnosis of spinal stenosis involves a complete evaluation of the spine. The process usually begins with a medical history and physical examination. X-ray and MRI scans are typically used to determine the extent and location of the nerve compression.
The normal lumbar central canal has a midsagittal diameter (front to back) greater than 13 mm, with an area of 1.45 cm 2. Relative stenosis is said to exist when the anterior-posterior canal diameter measures between 10 and 13 mm. Absolute stenosis of the lumbar canal exists anatomically when the anterior-posterior measurement is 10 mm or less.
Degenerative disc disease; Other names: Degenerative disc disorder, intervertebral disc degeneration: Degenerated disc between C5 and C6 (vertebra at the top of the picture is C2), with osteophytes anteriorly (to the left) on the lower portion of the C5 and upper portion of the C6 vertebral body.
Cervical disc herniations occur in the neck, most often between the fifth and sixth (C5–6) and the sixth and seventh (C6–7) cervical vertebral bodies. There is an increased susceptibility amongst older (60+) patients to herniations higher in the neck, especially at C3–4. [23]

Stenosis (from Ancient Greek στενός (stenós) 'narrow') is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture ).
Sectional organization of spinal cord. The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. [3] [4] Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous ...
