Abstract:
Objective:To compare the morphological differences of psoas major muscles between patients with lumbar disc herniation (LDH) of lower limb pain and lumbocrural pain based on CT imaging data.Methods:Sixty patients with LDH admitted to Department of Neurosurgery, 900 th Hospital of PLA Joint Logistic Team from January 2012 to February 2023 were included. According to clinical symptoms, they were divided into lower limb pain group and lumbocrural pain group ( n=30). 3D CT images of the psoas major muscles in the 2 groups were reconstructed; the longest transverse axis perpendicular to the longitudinal axis of the psoas major muscle was chosen as the cross-sectional area, and the maximum psoas major muscle cross-sectional area was calculated; maximum psoas major muscle cross-sectional area index (PI max) was defined as ratio of maximum psoas major muscle cross-sectional area and L 5 vertebral cross-sectional area. PI max difference between lower limb pain group and lumbocrural pain group was compared; PI max difference among patients with different pain degrees (visual analog scale [VAS] scores) or pain courses was further compared in both lower limb pain group and lumbocrural pain group. Pearson correlation was used to analyze the correlations of PI max with pain degree and pain course in the 2 groups. Results:PI max in lower limb pain group was significantly larger than that in lumbocrural pain group (0.62±0.05 vs. 0.54±0.04, t=7.320, P<0.001). PI max in patients with severe pain from both lower limb pain group and lumbocrural pain group was significantly smaller than that in patients with moderate pain (0.61±0.05 vs. 0.65±0.04, t=2.422, P=0.022; 0.53±0.03 vs. 0.58±0.04, t=3.502, P=0.002). PI max in patients with short pain course from both lower limb pain group and lumbocrural pain group was significantly larger than that in patients with long pain course (0.64±0.05 vs. 0.59±0.04, t=2.570, P=0.016; 0.57±0.04 vs. 0.53±0.03, t=2.941, P=0.007). Pearson correlation showed that PI max was negatively correlated with pain degree and pain course in LDH patients from both groups ( P<0.05). Conclusion:Atrophy of psoas major muscles in LDH patients is aggravated with increased pain degree and pain course.
