ABSTRACT
The lumbar intervertebral disc is a disc-shaped fibrocartilaginous structure located between the vertebral bodies and acts as an important anatomical structure in the spine for stability. The spinal stability system consists of three subsystems passive subsystem, active subsystem, and neural control subsystem. Lumbar intervertebral disc degeneration (IVDD), the leading cause of low back pain, induces pathological changes in other tissues of the three subsystems and interacts to degrade spinal stability. IVDD is commonly accompanied by degeneration of facet joint and ligament, Modic change, decreased vertebral blood flow, increased paraspinal muscle fat infiltration, reduced axial tension injury of the nerve, et al. Magnetic resonance imaging (MRI) is the preferred imaging modality for assessing spinal stability. Conventional MRI could completely demonstrate the morphological changes of the three subsystems in IVDD patients, and functional MRI could quantitatively evaluate the degree of pathophysiological change. We summarized the morphological and functional changes of MRI in lumbar intervertebral disc, facet joint, ligament, vertebral body, paraspinal muscle, and nerve of patients with IVDD, and then analysed the changes in spinal stability caused by IVDD, aiming to provide more imaging information for improving diagnosis accuracy and developing appropriate management of patients with low back pain.
