With the increasing prevalence of magnetic resonance imaging (MRI), lumbar spinal stenosis grading systems have been developed.

Demographic values, accompanying diseases, radiological staging of lumbar spinal stenosis, Oswestry Disability Index, Istanbul Low Back Pain Disability Questionnaire, Swiss Spinal Stenosis Questionnaire will be evaluated. Pain levels will be evaluated with Visual Analog Scale (VAS). Radiological stenosis level will be determined with Lee radiological spinal stenosis classification system. Those with and without stenosis will be determined. In addition, subgroup analysis will be performed by creating subgroups with mild, moderate and severe stenosis in the stenosis group. Evaluations will be made at the L4-L5 vertebrae level, where degenerative spinal stenosis is most frequently seen.
