Research On Relative Factors Of Lumbar Spinal Stenosis Disease Imaging Parameters Differentiation-type Of TCM

Objective:To observe and analyze the potential relevance between imageology parameters and syndromes of lumbar spinal stenosis disease (LSSD) with the expectation of providing microcosmic quantitative index for the application of Chinese medicine to the LSSD.Method:We select 78 qualified cases and record their basic conditions and symptoms in detail so that we can roughly divided them into three categories of obstructive syndrome due to wind and cold,syndrome of qi deficiency and blood obstruction,syndrome of kidney-qi deficiency. In addition, through the medical scan of CT and MRI,we measure a lot of values,such as the cross sectional area of centrum,canalis spinalis,dural sac, the angle and radius vector of lateral recess,transverse diameter and radius vector of centrum,canalis spinalis.Then, we do the statistic analysis on these data to find the relevance with the syndrome of TCM.Result:We collect 46 male cases(59%) versus 32 female cases(41%).There is no statistic significance as for the difference in case number of three categories though the case number of kidney-qi deficiency (29) or qi deficiency and blood obstruction (27) is a little bit more than that of the category of obstructive syndrome due to wind and cold (22). Through chi-square test, there is statistic significance for the imageology constitutent ratio of the three syndromes showing significant differences of the stenosis in different syndrome. Moreover,there are significant differences in lots of parameters as the angle and radius vector of lateral recess,radius vector of lateral recess,the ratio of the radius vector of lateral recess and canalis spinalis,canalis spinalis area,dural sac area,the ratio of the canalis spinalis area and vertebral area,the ratio of dural sac area and canalis spinalis area,radius vector of canalis spinalis,the ratio of radius vector of canalis spinalis and vertebral radius vector,the ratio of transverse diameter of canalis spinalis and vertebral transverse diameter and vertebral transverse diameter and vertebral indexConclusion:The type of stenosis varies in different syndromes.Most of LSSD with central type are differentiated as the obstructive syndrome due to wind and cold; the main syndrome for the peripheral type is qi deficiency and blood obstruction; kidney-qi deficiency syndrome is frequently seen in the mixed type.There is certain relevance between the parameters of imagiology and syndromes of TCM. In the comparison of some of the parameters among the three syndromes, the angle and radius vector of lateral recess as well as the ratio of the radius vector of lateral recess and canalis spinalis of obstructive syndrome due to wind and cold diminish gradually in the order of obstructive syndrome due to wind and cold,kidney-qi deficiency syndrome and qi deficiency and blood obstruction, while the canalis spinalis area,dural sac area,the ratio of canalis spinalis area and vertebral area,the raito of the dural sac area and canalis spinalis area are increasing gradually in this order. The parameters like the radius vector of canalis spinalis,the ratio of radius vector of canalis spinalis and vertebral radius vector,the ratio of transverse diameter of canalis spinalis and vertebral transverse diameter are maximum in the syndrome of qi deficiency and blood obstruction. The vertebral index of kidney-qi deficiency syndrome is larger than that of obstructive syndrome due to wind and cold and the vertebral index of qi deficiency and blood obstruction is the smallest.
