腰椎终板ModicⅡ型面积改变率与慢性下腰痛之间的相关性研究

摘要

目的：研究腰椎终板ModicⅡ型面积改变率与慢性下腰痛之间的相关性。方法检测45例ModicⅡ型患者的腰椎终板面积改变率，并采用疼痛视觉模拟评分（VAS）来评估慢性下腰痛的程度。结果所有45例ModicⅡ型患者均进行MRI检查后，统计得出Modic改变率为（15.13±10.75）％，计算VAS评分为（3.90±0.40）分， ModicⅡ型患者的面积改变率与VAS评分经Pearson相关分析，呈正相关性（r=0.31，P＜0.05）。结论腰椎终板Modic Ⅱ型面积改变率与慢性下腰痛之间具有正相关性，即终板面积改变率越大，患者下腰痛程度越严重。%Objective To study the relationship between the change area rate of Modic II of lumbar endplate and chron-ic low back pain (CLBP). Methods The change rate of lumbar endplate area of 45 Modic Ⅱcases was detected and vi-sual analogue scale (VAS) was used to assess the degree of CLBP. Results All 45 cases of Modic Ⅱpatients underwent MRI examination, the ModicⅡarea change rate was (15.13±10.75)%, VAS score was (3.90±0.40). Pearson correlation analysis showed that Modic Ⅱ area change rate and VAS scores were positively related (r=0.31, P<0.05). Conclusion Modic Ⅱ area change rate and the CLBP are positively related. The larger of endplate Modic Ⅱ area change rate is, the more severity in patients with low back pain.
