Introduction: Lumbar spinal stenosis is a severe degenerative condition of the spinal channel with its concentric narrowing with presence of specific clinical syndrome. The relationship between its symptoms and dural sac diameter is not apparent .With relation to the numerous difficulties one encounters in going ahead with the therapy for patients with lumbar canal stenosis, this study aims to find any correlation between degree of spinal canal narrowing based on the canal anatomy and the patients functional status based on Oswestry disability index scores to provide a definitive management guideline. Methodology: 121 patients with clinical suspicion of stenosis on the basis of ODI score and canal anatomy by the means of MRI were studied where in the lumbar spinal canal was evaluated on the basis of dural sac crossectional area (DSCA), mid sagittal diameter (MSD) and separation of cauda equina (SCE).The relationship between the ODI and canal anatomy was established. Observations and Results: Oswestry Disability Indices of patients were obtained and classified as mild, moderate, severe, crippled and bedridden. On imaging central canal stenosis was classified separately on the basis of DSCA, MSD and SCE depending on their MRI findings. Percentages of patients belonging to each group was determined and with the help of a chi square test a correlation was established between severity of radiological stenosis and clinical function. Conclusion: No significant correlation found between radiological central canal stenosis and ODI in clinically suspected cases of lumbar spinal stenosis.
