Objectives : This study was conducted to find out the correlation between lumbar malposition and lumbar disc herniation.
Methods : Among the patients who visited Gwangju Jaseng Hospital of Korean Medicine from January 2019 to January 2021, taking 92 patients under age 60 who had the records of X-rays and magnetic resonance imaging (MRI) images as the research subjects, Cobb's angle was measured in anterior-posterior (AP) view and lateral (LAT) view, the number of displacements was scored by listing categories defined by The Korean Society of Chuna Manual Medicine for Spine and Nerves. The degree of lumbar intervertebral disc herniation was expressed as a percentage according to the method of Kato, etc., and the correlation between each factor was analyzed.
Results : AP curvature and MRI herniation index showed significant positive correlation in L4-L5 level but there was no significant difference in L5-S1 level. LAT curvature and MRI herniation index had no correlation in L4-L5 level, but there was a significant negative correlation in L5-S1 level. Malposition score and MRI herniation index had a significant positive correlation in L5-S1 level, whereas there was no correlation in L4-L5.
Conclusions : As a result of the study, AP curvature and MRI herniation index showed a significant positive tendency in L4-L5 lumbar spine, and LAT curvature and MRI herniation index showed a significant negative tendency in L5-S1 lumbar spine. Malposition score and MRI herniation index were found to have a significant positive tendency in
L5-S1 lumbar spine.
