文题释义:
腰椎黄韧带肥厚:黄韧带是连接上下相邻2个椎板的黄色弹性韧带,起到维持脊柱固有稳定性、控制椎间运动、保持硬膜后囊表面光滑的作用。黄韧带肥厚被认为是腰椎管狭窄发展中的重要致病因素之一,肥厚的黄韧带压迫硬膜囊和根,进而出现腰痛和坐骨神经痛。黄韧带肥厚的原因是多方面的,包括年龄、脊柱机械应力和生长因子等。
脊柱-骨盆矢状面平衡:是对脊柱曲度形态、骨盆角度位置的描述,包括胸椎后凸角、腰椎前凸角、骶骨倾斜角、骨盆入射角、骨盆倾斜角和矢状面平衡。这对患者脊柱疾病的发生、发展及预后起到一定的预测和评估作用。
 
摘要
背景:腰椎黄韧带肥厚存在多种发病机制,但是否与脊柱-骨盆矢状面平衡存在相关性,目前尚不清楚。
目的:分析腰椎黄韧带肥厚与脊柱-骨盆矢状面平衡参数间的关系。
方法:回顾性分析2015年1月至2017年12月收入院治疗腰椎退行性疾病38例患者的临床资料,在患者站立位脊柱全长正侧位X射线片上进行脊柱-骨盆矢状面参数的测量,包括胸椎后凸角、腰椎前凸角、骶骨倾斜角、骨盆入射角、骨盆倾斜角和矢状面平衡。在患者腰椎MRI轴位关节突层面T2WI图像上对L1-2,L2-3,L3-4,L4-5,L5-S1节段黄韧带厚度进行测量;将黄韧带≤3 mm者作为正常组,>3 mm者为肥厚组,分析腰椎黄韧带肥厚与脊柱-骨盆矢状面平衡参数间的关系。
结果与结论:①各节段性别、体质量指数黄韧带正常组与肥厚组间差异均无显著性意义(P > 0.05),而年龄组间差异有显著性意义(P < 0.05);②L1-2节段胸椎后凸角组间比较差异有显著性意义(P < 0.05),L2-3节段胸椎后凸角、骨盆倾斜角组间比较差异有显著性意义(P < 0.05),L3-4节段胸椎后凸角组间比较差异无显著性意义(P=0.054),L4-5节段腰椎前凸角组间比较差异有显著性意义(P < 0.05),L5-S1节段各参数间比较差异均无显著性意义;③L5-S1节段黄韧带厚度与矢状面平衡存在负相关关系(r=-0.33,P < 0.05);④提示黄韧带肥厚与脊柱-骨盆矢状面参数存在密切联系。

Abstract:

BACKGROUND: The pathogenesis of hypertrophy of lumbar ligamentum flavum is complex, and whether it is related to the sagittal spinopelvic balance remains unclear.

OBJECTIVE: To investigate the relationship between hypertrophy of lumbar ligamentum flavum and sagittal spinopelvic balance parameters.
METHODS: A retrospective analysis of the clinical data of 38 patients with lumbar degenerative diseases admitted to hospital from January 2015 to December 2017 was conducted. The sagittal spinopelvic balance parameters, including thoracic kyphosis, lumbar lordosis, sacral slope, pelvic incidence, pelvic tilt, sagittal vertical axis, were measured on the full-length radiographs in standing position. The thickness of lumbar ligamentum at L1-2, L2–3, L3–4, L4–5, L5–S1 was measured on the axial T2-weighed MR images at the facet joint level. In order to analyze the relationship between hypertrophy of lumbar ligamentum flavum and sagittal spinopelvic balance parameters, patients were divided into normal group (thickness of ligamentum ≤ 3 mm) and hypertrophy group (thickness of ligamentum > 3 mm)
RESULTS AND CONCLUSION: (1) There was no significant difference in the sex and body mass index between two groups at each segment (P > 0.05), but age showed significant difference (P < 0.05). (2) There was significant difference in the thoracic kyphosis at L1-2 between groups (P < 0.05). There were significant differences in the thoracic kyphosis and pelvic tilt at L2-3 between groups (P < 0.05). There was no significant difference in the thoracic kyphosis at L3-4 between groups (P=0.054). There was significant difference in the lumbar lordosis at L4-5 (P < 0.05). The parameters at L5-S1 showed no significant difference between groups. (3) There was a negative correlation between L5-S1 thickness and sagittal vertical axis (r=-0.33, P < 0.05). (4) To conclude, hypertrophy of ligamentum flavum is closely related to the sagittal spinopelvic balance parameters.
