Abstract :Aim: The aim of our study; to investigate the location of hypertrophy in the epidural adipose tissue in the lumbar spinal stenosis clinic, to compare the area measurements of the spinal canal and dural sac in patients with a preliminary diagnosis of lumbar spinal stenosis or radiculopathy, and to determine the place of the superior articular process area measurement in the diagnosis of spinal stenosis. Material and Method: 180 patients aged 50-69 years who underwent Lumbar Magnetic Resonance Imaging were divided into two groups according to the prediagnosis of lumbar spinal stenosis or radiculopathy and retrospectively analyzed. Spinal canal, dural sac, epidural fat, and superior articular process areas were measured. Statistical relationships of the findings were investigated. Results: There was no difference between the stenosis groups of these patients in terms of age and gender insert ignore into journalissuearticles values(respectively p=0.078; p=0.564);. There is a significant difference in terms of the spinal canal, dural sac, superior articular process, and epidural fat widths between spinal stenosis and radiculopathy insert ignore into journalissuearticles values(p<0.001; p<0.001; p<0.001; p=0.033, respectively);. Superior articular process, spinal canal, dural sac, and epidural fat cross-sectional areas were each found significant for their use as a diagnostic test for diagnosing lumbar spinal stenosis insert ignore into journalissuearticles values(p<0.001; p<0.001; p<0.001; p=0.034, respectively);. Conclusion: Spinal stenosis is a problem that greatly affects the quality of life of patients. Measuring only the width of the spinal bony canal does not provide sufficient information in the diagnosis of spinal stenosis. In our study, hypertrophy of the superior articular process was the strongest finding in the diagnosis of lumbar spinal stenosis. Hypertrophy of epidural adipose tissue has also been shown to be a risk factor for lumbar spinal stenosis. In radiological evaluations, other structures that narrow the canal should also be carefully examined.
