摘　　要：目的探讨移位的内侧半月板桶柄状撕裂MRI表现特点。方法回顾性分析我院2011年4月~2015年8月12例经关节镜证实的膝关节移位的半月板桶柄状撕裂资料。结果 12例均为单侧发病,均伴以下征象：碎块内移征、双后交叉韧带征、半月板翻转征和双前角征、外周残半月板征、领结残破征及后角残破征。结论移位的内侧半月板桶柄样撕裂有较为特征性的MRI表现,MRI可作为内侧半月板桶柄样撕裂的一种较佳的影像学检查手段。Objective To investigate the MRI findings of displaced bucket-handle tear in medial meniscus. Methods From April 2011 to August 2015 in our hospital, the clinic and MRI data of 12 patients with displaced bucket-handle tear in medial meniscus confirmed by arthroscopy were retrospectively analyzed. Results 12 cases were unilateral.Fragment shift sign, double posterior cruciate ligament sign, flipped meniscus sign and double meniscus forefoot sign,abnormal circumferential meniscus sign, bow tie broken sign and disproportional posterior horn sign could be seen in all cases. Conclusion Displaced bucket-handle tear in medial meniscus has some characteristic manifestations on MRI,MRI can be used as a preferred imaging methods for displaced bucket-handle tear in medial meniscus.
