INTRODUCTION: Lower back pain secondary to degenerative disc disease is a
condition that affects young to middle-aged persons with peak incidence at
approximately 40 y. MRI is the standard imaging modality for detecting disc
pathology due to its advantage of lack of radiation, multiplanar imaging
capability, excellent spinal soft-tissue contrast and precise localization of
intervertebral discs changes. AIMS AND OBJECTIVE: To evaluate the
characterization, extent, and changes associated with the degenerative lumbar
disc disease by Magnetic Resonance Imaging. STUDY DESIGN: Cross-sectional and
observational study. MATERIALS AND METHODS: A total 109 patients of the lumbar
disc degeneration with age group between 17 to 80 y were diagnosed & studied on
1.5 Tesla Magnetic Resonance Imaging machine. MRI findings like lumbar lordosis,
Schmorl's nodes, decreased disc height, disc annular tear, disc herniation, disc
bulge, disc protrusion and disc extrusion were observed. Narrowing of the spinal
canal, lateral recess and neural foramen with compression of nerve roots
observed. Ligamentum flavum thickening and facetal arthropathy was observed.
RESULT: Males were more commonly affected in Degenerative Spinal Disease & most
of the patients show loss of lumbar lordosis. Decreased disc height was common at
L5-S1 level. More than one disc involvement was seen per person. L4 - L5 disc was
the most commonly involved. Annular disc tear, disc herniation, disc extrusion,
narrowing of spinal canal, narrowing of lateral recess, compression of neural
foramen, ligamentum flavum thickening and facetal arthropathy was common at the
L4 -L5 disc level. Disc buldge was common at L3 - L4 & L4 - L5 disc level.
Posterior osteophytes are common at L3 - L4 & L5 -S1 disc level. L1- L2 disc
involvement and spondylolisthesis are less common. CONCLUSION: Lumbar disc
degeneration is the most common cause of low back pain. Plain radiograph can be
helpful in visualizing gross anatomic changes in the intervertebral disc. But,
MRI is the standard imaging modality for detecting disc pathology due to its
advantage of lack of radiation, multiplanar imaging capability, excellent spinal
soft-tissue contrast and precise localization of intervertebral discs changes.
