Background: Lumbar spinal canal stenosis (LSCS) is an important cause of morbidity in the elderlypopulation. Many morphological abnormalities such as facet joint hypertrophy, ligamentum flavumhypertrophy, disc herniation combined with osteophytes associated with LSCS were investigated.Degenerative changes in all the elements of the vertebral bone such as lumbar pedicle thickness (LPT)has not evaluated clearly. The aim of this study to investigate whether LPT can be a morphologicalparameter to predict LSCS using magnetic resonance imaging (MRI).Materials and Methods: 150 patients diagnosed clinical LSCS and 150 control subjects who did nothave LCSC-related symptoms referred to radiology unit to undergo lomber MRI enrolled the study.LPT was measured at the most stenotic level of the L5 vertebra using axial T2-weighted images.Results: The mean LPT value was 14.70±1.94 mm in the LSCS group and 14.23±2.00 mm in thecontrol group and was higher in patient group than the controls but did not reach statistical significance(p=0.082).Conclusion: LPT cannot be an effective factor to predict patients with LSCS.
