| Abstract:Objective：To investigate the magnetic resonance imaging (MRI) features of acute and subacute lower back pain, and to evaluate its clinical significance. Methods：A total of 177 consecutive patients underwent lumbar MRI examination due to low back pain in our hospital were retrospectively reviewed. According to the duration of disease, patients were divided into group A (subacute low back pain group, 103 cases) and group B (acute low back pain group, 74 cases), and 42 cases without low back pain were recruited as normal control group, group C. The degrees of low back pain were based on the visual analogue scale (VAS). The MRI findings including disc degeneration, disc bulging, disc herniation, posterior high signal of fibrous rings, Schmorl nodes, Modic changes, facet joints degeneration, facet joint effusion, high T2 signal in interspinous ligament, and subcutaneous/paraspinal muscles edema were analyzed. The distribution difference of magnetic resonance findings in the three groups above were analyzed. Results：The incidences of disc degeneration and disc herniation of group A and group B were higher than that in group C (P<0.05). There was no statistical difference in disc bulging, Schmorl nodes, and Modic changes among the three groups. The findings of posterior high signal of fibrous rings, interspinous ligament high signal, subcutaneous or paraspinal muscles edema in group B were more prevalent than those in group A and group C(P<0.05). The incidence of facet joints degeneration, facet joint effusion in group A was higher than those in group B and group C (P<0.05). Conclusions：The degeneration and herniation of the intervertebral disc may be the main cause of the persistent symptoms of low back pain. Posterior high signal of fibrous rings, high signal in interspinous ligament and subcutaneous or paraspinal muscles edema may be the cause of pain in patients with acute low back pain. Facet joints degeneration and facet joints effusion may be related to the subacute low back pain. |
