Abstract

Abstract Objective The purpose of this study is to explore the morphological differences of Paravertebral muscle in patients with only L4-5 lumbar disc herniation (LDH) under different Michigan State University (MSU) classification, so as to better reveal the relationship between LDH and paravertebral muscle, so as to further reveal the causative causes and guide the treatment of LDH.Methods The study included 160 patients including 39 normal patients and 121 patients with single level L4-5 LDH. Patients with LDH were grouped according to MSU classification and compared to the normal group according to the demographic and Imaging change.Results In patients with L4-5 herniation in Zone B, the FI of ES muscle at L3-4 level, L4-5 level and L5-S1 level was higher than that of normal people (P = 0.018, P = 0.043, P = 0.010), and there was no difference between FI of MF and normal people. The Zone B patients also have a smaller CSA of ES muscle at L45 level than that in the normal group (P = 0.049). Patients in Zone C group were older than those in normal group (P = 0.014). While the CSA of the PM of patients with Grade 3 herniation is different from that of the normal group at the L4-5, L5-S1 level. They were higher than normal people at L4-5 level (P = 0.011) and lower at L5-S1 level (P = 0.028).Conclusion In patients with L4-5 herniation in Zone B, the FI of ES at L3-S1 level was higher than normal, and the CSA at L4-5 level was smaller than normal. In patients with Grade3 herniation, PM CSA is large at L4-5 level and small at L5-S1 level than normal people.
