磁共振成像对膝关节半月板桶柄样撕裂的评估作用

MRI evaluation of the bucket handle tears(BHT) of meniscus of knee

目的分析半月板桶柄样撕裂的影像表现。方法回顾性分析44例半月板桶柄样撕裂患者的临床症状、膝关节磁共振影像表现。结果半月板桶柄样撕裂的征象主要包括碎块内移征38例,空领结征37例,外周残半月板征44例,半月板翻转征17例,双后交叉韧带征24例,厚饼征12例,三韧带征7例。结论膝关节MRI扫描可清楚显示能显示半月板桶柄样撕裂的典型征象,对半月板损伤的判定对治疗方案的选择有重要辅助作用。

Objective Analysed the performance of magnetic resonance imaging of the bucket handle tears （BHT） of meniscus of knee. Methods Retrospective analysis the clinical symptoms, MRI scanning methods and imaging performance of 44 cases with he bucket handle tears （BHT） of meniscus of knee. Results The main MRI signs of Bucket handle tear meniscus include internal displaced fragment sign 38 cases, absent bow tie sign 37 cases, abnormal circumferential meniscus sign 44 cases, flipped meniscus sign 17 cases, double posterior cruciatc ligament sign 24 cases, lhick cake sign 12 cases, triplc Iigament signs 7 cases. Conclusion MRI scan can clearly show the main signs of buekct handle tears （BHT） of meniscus of knee, offering an important supporting role of judgmenl on the meniscus on treatment options.
