Spinal MRI shows extensive and prominent degenerative changes such as ligamentum flavum hypertrophy, thickening of anterior and posterior longitudinal ligaments, vacuum phenomena, reduced intervertebral disc spaces and multiple Schmorl's nodes with multiple prolapsed discs.
The main causes of spinal canal and neuroforaminal narrowing in the lumbar spine include disc herniation, facet hypertrophy, and ligamentum flavum hypertrophy/infolding.
Lower back pain/extremity numbness is frequently caused by the degenerative condition known as lumbar spinal stenosis: the narrowing of the spinal canal caused by the overgrowth of ligamentum flavum.
For the same reason, the incidence of CSFL increases to more than 20% in PD patients when the diagnosis includes ossification of ligamentum flavum (OLF),[sup][1],[5],[22],[27] considering the occurrence of adhesion between OLF and the dural sac behind the spinal cord.
MRI (Figure-4-5) of cervical and dorso-lumbar spine showed diffuse low signal marrow, hypertrophy of ligamentum flavum, causing canal stenosis and compression of the cord at multiple levels especially at D7-D8.
Visibility degrees of the anatomic structures in vertebral space (spinous process vertebral bone ligamentum flavum dura mater static bladder) observed through ultrasound were numerically scored using the following values:
In the midline technique, the needle is inserted below the lower edge of the spinous process of the selected upper vertebrae and passes through the skin, subcutaneous tissue, supraspinous ligament, interspinous ligament, ligamentum flavum as well as the epidural space until it reaches dura arachnoids and pierces it.
Pathophysiological factors in CSM Mechanical Static Congenital canal stenosis Cervical disc prolapse Vertebral osteophyte formation Hypertrophic ossification of PLL Ligamentum flavum hypertrophy Facet/unconvertable hypertrophy Dynamic Repetitive movements Primarily in sagittal plane Poor cord elasticity Ischaemic Compression of larger arteries Decreased pia/medullary flow Venous congestion PLL - posterior longitudinal ligament.
Significant spinal canal stenosis at L4/5 level was seen due to a degenerative posterior disc bulge as well as a 2 x 1 x 1 cm size well capsulated, well defined lesion seeming to arise fromthe ligamentum flavum contributing to the canal narrowing.
There were no significant differences between the groups for the simulation of the ligamentum flavum.
The narrowing typically is caused by three pathoanatomic abnormalities occurring together: thickening of the normally paper-thin ligamentum flavum, facet joint osteoarthritis, and disc protrusion.
