摘要: 本研究的目的是探讨腰椎矢状面屈曲角、终板屈曲深度和双侧腰大肌横断面积差值诊断腰椎间盘突出症(LDH)的价值及与椎间盘退变程度的关系。选取LDH患者120例作为观察组,同时选取体检健康者100例作为对照组,均给予腰椎CT检查。实验结果显示,观察组L3~S1平均终板屈曲深度、平均矢状面屈曲角、平均腰大肌横断面积与对照组比较,差异有统计学意义(P<0.05);观察组Pfirrmann分级Ⅳ~Ⅴ级的患者L3~S1平均终板屈曲深度、平均矢状面屈曲角、平均腰大肌横断面积差值与Ⅱ~Ⅲ级患者比较,差异有统计学意义(P<0.05);L3~S1平均终板屈曲深度、矢状面屈曲角、腰大肌横断面积差值诊断Pfirrmann分级Ⅳ~Ⅴ级的ROC曲线下面积分别为0.601、0.890和0.771。本研究证实矢状面屈曲角、终板屈曲深度、双侧腰大肌横断面积差值与LDH患者椎间盘退变程度有一定关系,诊断椎间盘退变程度有一定价值。

Abstract: The purpose of this study was to investigate the value of sagittal lumbar flexion angle, end plate flexion depth and the difference of cross-sectional area of bilateral psoas major muscle in the diagnosis of lumbar disc herniation (LDH), as well as the relationship with the degeneration. We selected 120 cases of LDH patients as the observation group, and 100 healthy people as the control group. The Lumbar CT examination was performed on both groups. The results showed that there were statistically significant differences between the observation group and the control group in the following items:the average endplate buckling depth, the average sagittal plane buckling angle and the average psoas major cross-sectional area (L3-S1). Compared with patients of Pfirrmann grading Ⅱ-Ⅲ in observation group, the average depth of the end plate buckling of L3-S1 had statistically significant 386 differences with those of patients in Pfirrmann grading Ⅳ-Ⅴ, as well as the average sagittal buckling angle and the average psoas major cross sectional area (P<0.05). The area under the ROC curve of Pfirrmann grade Ⅳ-Ⅴ diagnosed by the three parameters were 0.701, 0.890 and 0.771. This study confirmed that Sagittal curvature angle, end plate flexion depth and the difference of cross-sectional area of bilateral psoas major muscle are related to the degree of intervertebral disc degeneration in patients with LDH, which has certain value in the diagnosis of intervertebral disc degeneration.
