Abstract:Objective: To explore and analyze the association of multifidus muscle fat ratio and cross-sectional area changes with pfirrmann grading and reabsorption of intervertebral disc nucleus pulposus after treatment in patients with lumbar disc herniation (LDH). Methods: Totally 105 patients with LDH admitted to the hospital from July 2020 to July 2023 were included. The changes of cross-sectional area and fat ratio of multifidus muscle were detected by magnetic resonance imaging (MRI), and the relationship with pfirrmann grading and reabsorption of intervertebral disc nucleus pulposus after treatment was analyzed. Results: There were statistical differences in the proportion of affected side, the muscle area of healthy L5/S1-pre pure multifidus muscle and healthy L5/S1-pre fat ratio between LDH patients with pre-pfirrmann grade 3 and grade 4 (P<0.05). The differences in age and affected L4/L5-post fat ratio among LDH patients with post-pfirrmann grade 3, grade 4 and grade 5 were statistically significant (P<0.05). The proportion of post-pfirrmann grading, affected/healthy L4/L5-post fat ratio and affected/healthy L5/S1-post fat ratio revealed no statistical differences between patients with reabsorption and without reabsorption (P<0.05). Logistic regression showed that the ratio of healthy L4/L5-post fat was a risk factor for reabsorption after treatment (P<0.05). ROC curves showed that the AUC of LDH reabsorption after LDH treatment as assessed by healthy L4/L5-post fat ratio was 0.729, respectively. Conclusion: The muscle area of healthy L5/S1-pre pure multifidus muscle and the fat proportion of healthy L5/S1-pre were different in different pre-pfirrmann grades, while the fat proportion of patients with L4/L5-post was different in different post-pfirrmann grades.Moreover, the healthy L4/L5-post fat ratio is related to reabsorption after LDH treatment, and has a certain evaluation value for reabsorption.
