English: Projectional radiograph of the neck of a 79 year old man presenting with pain at the nape and left shoulder, and radiating to the left arm. It shows stenosis of the left intervertebral foramen between cervical vertebra 3 and 4, indicating radiculopathy of cervical spinal nerve 4.
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.
Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.
They allow for flexion and extension and limit lateral flexion in the cervical spine. Pathological processes that can occur in these joints include degenerative changes or hypertrophic arthritis, resulting in foraminal stenosis and nerve compression. Foraminal stenosis at this joint is the most common cause of cervical nerve root pressure.
Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel ...
The posterior triangle (or lateral cervical region) is a region of the neck. Boundaries. The posterior triangle has the following boundaries: [1]
In the thoracic region and lumbar region, each vertebral foramen is additionally bounded anteriorly by (the inferior portion of) the body of vertebra (particularly in the thoracic region) and adjacent intervertebral disc (particularly in the lumbar region). [2]: 425 In the cervical region, a small part of the body of vertebra inferior to the ...
This contributes to narrowing the spinal canal and compressing the spinal cord in the corresponding region. Herniated disk due to tearing of the spinal disk over time, causes the disk to protrude and exert pressure on surrounding spinal nerve tissue. Consequent compression on the spinal cord at the cervical region causes CSM. [12]
