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.
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 ...
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]
In addition to spinal stenosis, other lower back conditions such as spondylosis, tumors, infections and herniated or ruptured discs can cause NC. These conditions contribute to the potential narrowing of the spinal cord, increasing pressure and inducing damage on the spinal nerve roots, thus, causing paing, tingling or weakness in the lower ...
Lumbar spinal stenosis is very prevalent with 9.3% of the general population producing symptoms and the number is continuing to rise in patients older than 60. [16] It's generally an indication for spinal surgery in patients older than 65 years of age. [17]
Spinal decompression is the relief of pressure on the spinal cord or on one or more compressed nerve roots passing through or exiting the spinal column. [1] Decompression of the spinal neural elements is a key component in treating spinal radiculopathy , myelopathy and claudication .
