Abstract:
Objective:To analyze the correlation between MRI indicators and clinical features of multifidus degeneration in patients with unilateral lumbar disc hemiation. Method:Eighty-six eligible patients with unilateral lumbar disc hemiation admitted to our hospital from Janu-ary 2018 to December 2021 with complete clinical data were retrospectively analyzed and divided into three groups according to the level and number of lumbar disc hemiation:27 patients in group A were treated with L4/5 disc hemiation only,30 patients in group B were treated with L5/S1 disc hemiation only,and 29 pa-tients with multi-level lumbar disc hemiation in group C.All patients underwent lumbar MRI scans,and the measurements included the ratio of the total cross-sectional area of the unaffected and affected sides of the multifidus muscle at L4/5 and L5/S1 levels,the degree of bilateral multifidus muscle atrophy,and the propor-tion of fatty infiltration.The lumbar visual analogue scale(VAS),Oswestry disability index(ODI)and other clinical features of patients with lumbar disc herniation were obtained from the medical records,and Spearman correlation was used to analyze the correlation between the ratio of the total cross-sectional area of the unaffect-ed and affected sides of the multifidus muscle at L4/5 and L5/S1 levels and the proportion of fatty infiltration. Result:There was no significant difference in age,gender and body mass index(BMI)between the groups(P＞0.05);the total cross-sectional area ratio of the unaffected and affected sides of the multifidus muscle in the three groups was positively correlated with the VAS score(P＜0.05)and not correlated with the ODI score(P＞0.05);the degree of bilateral multifidus muscle atrophy and the proportion of fatty infiltration were posi-tively correlated with the ODI score(P＜0.05)and not correlated with the VAS score(P＞0.05). Conclusion:In patients with unilateral lumbar disc herniation,the degree of asymmetry in the left and right cross-sectional areas of the multifidus muscle was associated with lumbar pain,whereas the degree of bilateral multifidus muscle atrophy and the proportion of fatty infiltration were associated with ODI scores.
