PURPOSE: This study aimed to investigate the association between the clinical symptoms of @entity2649 ( @entity2649 ) and morphological parameters using magnetic resonance imaging (MRI) data. METHODS: We retrospectively reviewed 117 @entity1 who visited our @entity158 clinic from 2009 to 2013 and were diagnosed as @entity2649 . All @entity1 underwent MRI of the L-spine and we measured the dural sac cross-sectional area (DSA), @entity2915 ( @entity2915 ), ligamentum flavum cross-sectional area (LFA) and ligamentum flavum thickness (LFT) at the most stenotic intervertebral level on MRI. Clinical outcomes were investigated using the @entity1 -assessed quantitative measurement of visual analog scale (VAS) and subjective disability was assessed by the @entity717 Index (ODI). Additionally, subjective walking distance (SWD) was also collected from electronic medical records. RESULTS: There were no statistically significant correlations found between the VAS score and the DSA, @entity2915 , LFA, and LFT. A statistically significant linear association existed between the DSA and @entity2915 and the subjective walking distance (r  =  0.201, P  =  0.045 and r  =  0.198, P  =  0.049, respectively) indicating that the larger the DSA or @entity2915 , the longer the SWD before the occurrence of @entity613 . The LFA and LFT were significantly correlated with the ODI score (r  =  0.249, P  =  0.007 and r  =  0.250, P  =  0.007, respectively). CONCLUSION: Larger LFA and LFT values are associated with higher ODI values. A larger DSA and @entity2915 are associated with a longer SWD before @entity613 occurs. To evaluate @entity2649 @entity1 , clinicians should more carefully inspect the integral morphological parameters than the individual morphological parameters.
