下腰痛患者腰椎间盘突出与椎间高度指数及腰椎前凸角的关系

Relationship between lumbar disc herniation and intervertebral height index and lumbar lordosis angle in patients with low back pain

目的分析下腰痛患者腰椎间盘突出与椎间高度指数及腰椎前凸角的关系。方法选取120例2019年1月—2021年6月河南大学第一附属医院收治的下腰痛患者纳入研究,根据腰间盘突出症发生情况分为对照组(非腰椎间盘突出症患者)、观察组(腰椎间盘突出症患者),各60例。观察分析腰椎间盘突出与椎间高度指数及腰椎前凸角间的关系。结果两组患者椎间高度指数由L_(1)-L_(2)-L_(5)-S_(1)呈上升趋势,且各节段椎间高度指数间存在明显差异,具有统计学意义(P<0.05),观察组较对照组L_(1)~L_(2)、L_(2)~L_(3)、L_(3)~L_(4)、L_(4)~L_(5)、L_(5)~S_(1)各节段椎间高度指数明显较低(t=5.117、4.938、3.645、3.645、5.589,P<0.001),差异有统计学意义(P<0.05);观察组较对照组腰椎前凸角明显较小(t=5.416,P<0.001),差异有统计学意义(P<0.05);采用Spearman相关分析法对腰椎间盘突出与椎间高度指数、腰椎前凸角的关系进行分析,结果表明腰椎间盘突出与L_(1)~L_(2)、L_(2)~L_(3)、L_(3)~L_(4)、L_(4)~L_(5)、L_(5)~S_(1)各节段椎间高度指数及腰椎前凸角呈负相关(r=-0.189、-0.216、-0.324、-0.308、-0.312、-0.275,P=0.011、0.008、0.002、0.001、0.001、0.003),具有较高的相关性(P<0.05)。结论下腰痛患者与腰椎间盘突出患者由L_(1)-L_(2)-L_(5)-S_(1)呈上升趋势,且下腰痛非椎间盘突出患者各节段椎间高度指数与腰椎前凸角均高于腰椎间盘突出患者,下腰痛患者腰椎间盘突出与椎间高度指数及腰椎前凸角存在相关性,在对腰椎间盘突出症诊断及治疗效果评估,椎间高度指数、腰椎前凸角是重要的参考指标。

Objective To analyze the relationship between lumbar disc herniation and intervertebral height index and lumbar lordosis Angle in patients with low back pain.Methods A total of 120 patients with low back pain admitted to our hospital from January 2019 to June 2021 were included in the study.According to the occurrence of lumbar disc herniation,they were divided into control group(non-patients with lumbar disc herniation)and observation group(patients with lumbar disc herniation),60 cases in each group.To observe and analyze the relationship be⁃tween lumbar disc herniation,intervertebral height index and lumbar lordosis angle.Results The intervertebral height index showed an upward trend from L_(1)-L_(2)-L_(5)-S_(1)in the two groups,and there was a significant difference between the intervertebral height index of each segment(P<0.05).The intervertebral height index of l_(1)-L_(2),L_(2)-L_(3),L_(3)-L_(4),L_(4)-L_(5)and L_(5)-S_(1)was significantly lower in the observation group than in the control group(t=5.117,4.938,3.645,3.645,5.589,P<0.001),and the difference was statistically significant(P<0.05).The lumbar lordosis angle in the observation group was significantly smaller than that in the control group(t=5.416,P<0.001),and the difference was statistically significant(P<0.05).Spearman correlation analysis was used to analyze the relationship between lumbar disc herniation,intervertebral height index and lumbar lordosis Angle.The results showed that lumbar disc herniation was negatively correlated with l_(1)-L_(2),L_(2)-L_(3),L_(3)-L_(4),L_(4)-L_(5),L_(5)-S_(1)intervertebral height index and lumbar lordosis Angle(r=-0.189,-0.216,-0.324,-0.308,-0.312,-0.275,P=0.011,0.008,0.002,0.001,0.001,0.003),with high correlation(P<0.05).Conclusion L_(1)-L_(2)-L_(5)-S_(1)showed an upward trend in patients with low back pain and patients with lumbar disc herniation,and the intervertebral height index and lumbar lordosis Angle of each segment of patients with low back pain without disc herniation were higher than those of patients with lumbar disc herniation.There was correlation between lumbar disc herniation and intervertebral height index and lumbar lordosis Angle in patients with low back pain.Intervertebral height index and lumbar lordosis Angle are important reference indexes in diagnosis and treatment evaluation of lumbar disc herniation.
