Retrospective radiologic study on a prospective patient cohort. To devise a qualitative grading of lumbar spinal stenosis (LSS), study its reliability and clinical relevance. Radiologic stenosis is assessed commonly by measuring dural sac cross-sectional area (DSCA). Great variation is observed thou...
