Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness, or weakness in the arms or legs. [1] Symptoms are typically gradual in onset and improve with leaning forward. [1]
In the lumbar spine it is commonly used to treat spinal claudication caused by spinal stenosis, and is considered the most effective treatment for this condition based on current evidence. [3] In the cervical and thoracic spine it is used to treat myelopathy caused by compression of the spinal cord itself.
Spinal stenosis may be congenital (rarely) or acquired (degenerative), overlapping changes normally seen in the aging spine. [6] [7] Stenosis can occur as either central stenosis (the narrowing of the entire canal) or foraminal stenosis (the narrowing of the foramen through which the nerve root exits the spinal canal). Severe narrowing of the ...
This medical treatment is usually accompanied by physiotherapy to increase back and stomach muscles. Thus, the spine can be both relieved and stabilized. [ 10 ] If these conservative measures do not bring about betterment, minimally invasive procedures such as a facet infiltration can be conducted to offer relief.
NC should therefore be distinguished from vascular claudication, which stems from a circulatory problem rather than a neural one. The term neurogenic claudication is sometimes used interchangeably with spinal stenosis. However, the former is a clinical term, while the latter more specifically describes the condition of spinal narrowing. [4]
A laminotomy is an orthopaedic neurosurgical procedure that removes part of the lamina of a vertebral arch in order to relieve pressure in the vertebral canal. [1] A laminotomy is less invasive than conventional vertebral column surgery techniques, such as laminectomy because it leaves more ligaments and muscles attached to the spinous process intact and it requires removing less bone from the ...
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.
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. They were characterized by Hubert von Luschka in 1858. [4] [5]
