| Objective: A comparative analysis of the radiographic(X-ray)parameters of the spine and pelvis of healthy and asymptomatic Korean and Han nationalities in Yanbian area provides a reference for clinical prevention and treatment of spine and pelvic diseases.Methods: A retrospective analysis of standing position and full spine X-rays of volunteers who were asymptomatic and without known spine and large joint diseases in the outpatient clinic of Yanbian University Hospital from August 2017 to January2021.A total of 160 cases met the requirements,including 76 cases of Korean nationality(male:30,female:46),84 Han nationality(male:35,female:49),aged18-49,with an average age of 27.The angle and distance can be directly measured and read in the software PACS image browsing system,and all parameters are kept to one decimal place.The statistics before the filming include: ethnicity,gender,and age.The data that needs to be measured in the later stage of the filming mainly include pelvic incidence angle(PI),pelvic tilt angle(PT),sacral slope(SS),lumbar lordosis(LL),thoracic kyphosis(TK)and sacral sacral angle(SSA).According to Roussouly classification criteria,the Korean and Han nationalities were classified into the sagittal view of the spine and pelvis,and the differences in the parameters of the spine and pelvis of the two ethnic groups were analyzed.Result:1.Comparative analysis of various variables among ethnic groups: There is no statistically significant difference in Roussouly typing composition between the Han and Korean ethnic groups(P>0.05);the difference between PI and SS between the two ethnic groups is statistically significant(P<0.05).PI and SS are higher than the Koreans.2.Comparative analysis of variables of the same nationality and different genders: In the Han nationality,only the difference in PT between men and women was statistically different(P<0.05),and the PT of men was lower than that of women;In the Korean nationality,there was no statistically significant difference in each variable between men and women(P>0.05).3.Comparative analysis of variables between different ethnic groups and the same sex: Among men,the differences between the variables between the two ethnic groups are not statistically significant(P>0.05);among women,only the difference in PI between the two ethnic groups There is statistical significance(P<0.05).The PI of Han women is higher than that of Korean women.4.After Pearson correlation analysis,there is no correlation between age and each variable(P>0.05),PI and PT(r=0.481,P=0.000),SS(r=0.796,P=0.000),LL(r=0.459),P=0.000),SSA(r=0.550,P=0.000)has a positive correlation.PT only has a positive correlation with PI(r=0.481,P=0.000),SS and PI(r=0.796,P=0.000),LL(r=0.569,P=0.000),SSA(r=0.658,P= 0.000),there is a positive correlation between LL and PI(r=0.459,P=0.000),SS(r=0.569,P=0.000),TK(r=0.219,P=0.005),SSA(r=0.446,P= 0.000)There is a positive correlation.TK only has a positive correlation with LL(r=0.219,P=0.005),SSA and PI(r=0.550,P=0.000),SS(r=0.658,P=0.000),LL(r=0.446,P= 0.000)There is a positive correlation.Conclusion:1.The PI and SS of Han nationality in Yanbian area are greater than those of Korean nationality,and the difference between women of the two ethnic groups is the largest,and the average PI of Korean nationality women is the smallest.There is a positive correlation between spine and pelvic parameters.2.In the prevention of lumbar spine diseases and the formulation of surgical plans,the differences between ethnic groups should be fully considered. |
