目的研究腰痛患者腰骶椎Modic改变(Modic changes,MCs)及其类型与骨质疏松的关系。方法选取2021年1月至2024年9月于南京中医药大学附属徐州市中医院就诊的女性腰痛患者204例为研究对象,根据磁共振成像结果将患者分为MCs组(139例)和无MCs...目的研究腰痛患者腰骶椎Modic改变(Modic changes,MCs)及其类型与骨质疏松的关系。方法选取2021年1月至2024年9月于南京中医药大学附属徐州市中医院就诊的女性腰痛患者204例为研究对象,根据磁共振成像结果将患者分为MCs组(139例)和无MCs组(65例),将MCs组按MCs分型分为Ⅰ型组(33例)、Ⅱ型组(90例)和Ⅲ型组(16例)。比较各组患者的年龄、髋部骨密度(bone mineral density,BMD)及其T值。结果MCs组和无MCs组患者的年龄、髋部BMD及相应T值比较差异均无统计学意义(P>0.05)。四组患者的髋部BMD及相应T值依次为Ⅲ型组>无MCs组>Ⅱ型组>Ⅰ型组。Ⅲ型组患者骨量多处于正常水平,其余三组患者多处于骨量减少或骨质疏松水平。Ⅱ型组与无MCs组患者的髋部BMD及相应T值比较差异均无统计学意义(P>0.05),Ⅲ型组患者的髋部BMD及相应T值均显著高于其余三组(P<0.05)。Ⅰ型组患者的髋部BMD及相应T值均显著低于其余三组(P<0.05)。结论腰痛患者不同的骨量水平有不同的MCs发病倾向:较高骨量(骨量正常)者多发生Ⅲ型MCs,骨量减少或骨质疏松者则易发Ⅰ型MCs,应重视Ⅰ型MCs患者的抗骨质疏松治疗。展开更多
