Specialty: Orthopedics: Symptoms: Pain, numbness, or weakness in the low back, buttocks, or legs typically worsened with prolonged walking or standing and relieved with sitting or lying down: Usual onset ...
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.
Lumbar spinal stenosis is formally defined as a decline in diameter length of either the neural foramina, lateral recess, or spinal canal. [1] Stenosis is classified as a decaying disease because it causes the canal to gradually become more and more narrow which can cause pain or loss of function. [1]
MRI of the lumbar spine showing spinal stenosis. Neurogenic claudication is one subtype of the clinical syndrome of lumbar spinal stenosis (LSS). [9] No gold standard diagnostic criteria currently exist, but evaluation and diagnosis is generally based on the patient history, physical exam, and medical imaging. [1]
The lateral recess or lateral recess of fourth ventricle, is a projection of the fourth ventricle which extends to the lateral border of the brainstem at the pontomedullary junction. [1] [2] At this point the fourth ventricle is at its widest. [1] The lateral recess on each side opens into a lateral aperture (foramen of Luschka) that opens into ...
It is typically used as an adjunct to laminectomy, laminotomy, neural decompression, and facetectomy, in lieu of standard lumbar fusion. [1] The prosthesis is indicated for back and leg pain caused by central or lateral spinal stenosis , degenerative disease of the facets with instability, and grade 1 degenerative spondylolisthesis with ...
