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.
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.
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.
In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
Central cord syndrome (CCS) is the most common form of cervical spinal cord injury (SCI). It is characterized by loss of power and sensation in arms and hands. It usually results from trauma which causes damage to the neck, leading to major injury to the central corticospinal tract of the spinal cord. [1]
When the spinal canal diameter divided by vertebral body diameter is less than 0.82, or the anteroposterior diameter of the spinal canal is less than 1.3cm or the distance between the pedicles is less than 2.3cm during imaging, cervical spine stenosis is diagnosed symptoms correlate well with the spinal canal narrowings.
