MRI was used to measure the changes in the angle of the facet joints of the lumbar spine and analyze the relationship between it and the herniated lumbar intervertebral disc. Analysis of the causes of lumbar disc herniation from the anatomy and morphology of the spine provides a basis for the early diagnosis and prevention of lumbar disc herniation. There is a certain correlation between the changes shown in MRI imaging of lumbar disc herniation and the TCM syndromes of lumbar intervertebral disc herniation. There is a correlation between the syndromes of lumbar disc herniation and the direct signs of MRI: pathological type, herniated position, and degree of herniation. Indirect signs with MR, nerve root compression and dural sac compression, are related. The MRI examination results can help syndrome differentiation to improve its accuracy to a certain extent. MRI has high sensitivity for the measurement of the angle of the facet joints of the lumbar spine and can be used to study the correlation between the changes of the facet joint angles and the herniated disc. Facet joint asymmetry is closely related to lateral lumbar disc herniation, which may be one of its pathogenesis factors. The herniated intervertebral disc is mostly on the sagittal side of the facet joint, and the facet joint angle on the side of the herniated disc is more sagittal. The asymmetry of the facet joints is not related to the central lumbar disc herniation, and the angle of the facet joints on both sides of the central lumbar disc herniation is partial sagittal.
MRI 用于测量腰椎小关节角度的变化，并分析其与腰椎间盘突出症之间的关系。从脊柱解剖学和形态学分析腰椎间盘突出症的病因，为腰椎间盘突出症的早期诊断和预防提供了依据。腰椎间盘突出症的 MRI 影像学表现与中医腰椎间盘突出症证候存在一定相关性。腰椎间盘突出症的证候与 MRI 的直接征象：病变类型、突出部位、突出程度具有相关性。MR 的间接征象神经根受压、硬脊膜囊受压存在相关性。MRI 检查结果有助于辨证分型，在一定程度上提高其准确性。MRI 对腰椎小关节角度的测量具有较高的敏感性，可用于研究小关节角度变化与椎间盘突出的相关性。小关节不对称与侧方型腰椎间盘突出症密切相关，可能是其发病因素之一。突出的椎间盘多位于小关节矢状面，且椎间盘突出侧小关节角更偏向矢状位。小关节不对称与中央型腰椎间盘突出症无相关性，中央型腰椎间盘突出症两侧小关节角呈偏矢状位。
