Although degenerative disc disease (DDD) and degenerative spondylolisthesis (DS) are two common causes of back pain in elderly, the association between the lumbarfacet joint angle and tropism in these conditions are still unclear.
To evaluate the difference in facet joint angles between normal population and lumbar degenerative disc disease and spondylolisthesis patient.
The angle of lumbar facet joints were retrospectively measured with magnetic resonance imaging (MRI) to determine whether there was a difference between degenerative diseases. MRI of patients with DDD, DS, and control group at facet joint between L3-4, L4-5 and L5-S1 level were measured in axial view (60 subjects in each group).
There was no difference infacetjoint angle in DDD (44.1 ± 11.9) and control (45.6 ± 8.9), but differed in DS (40.1 ± 10. 7) and control group (p = 0.010) at L4-5 level. Facet tropism showed difference between degenerative groups and control group at L4-5 level.
DS group showed difference in facet joints angle and tropism when compared with control population, while DDD showed difference only in facet tropism. In addition, longitudinal studies are needed to understand the clinical significant between facet joint angle and tropism in spinal degenerative diseases.
虽然椎间盘退变疾病（DDD）和退变性腰椎滑脱（DS）是老年人背痛的两个常见原因，但在这些情况下腰椎小关节角度与关节不对称性之间的关联仍不清楚。
评估正常人群与腰椎间盘退变疾病及腰椎滑脱患者之间小关节角度的差异。
通过磁共振成像（MRI）回顾性测量腰椎小关节的角度，以确定退行性疾病之间是否存在差异。在轴位视图下测量DDD患者、DS患者及对照组在L3-4、L4-5和L5-S1节段小关节的MRI（每组60例受试者）。
在L4-5节段，DDD组（44.1±11.9）与对照组（45.6±8.9）的小关节角度无差异，但DS组（40.1±10.7）与对照组有差异（p = 0.010）。在L4-5节段，退变组与对照组之间的小关节不对称性存在差异。
与对照组相比，DS组在小关节角度和关节不对称性方面存在差异，而DDD仅在小关节不对称性方面存在差异。此外，需要进行纵向研究以了解脊柱退行性疾病中小关节角度和关节不对称性之间的临床意义。
