The bucket-handle meniscal tear is a specific type of meniscal injuries which has specific signs on MRI. An attached fragment displaced away from the meniscus with any type of tear causes bucket-handle tear of the meniscus. Magnetic resonance imaging (MRI) is the most commonly used diagnostic tool for meniscal injuries. We present a case of free medial meniscal fragment which mimics the dislocated bucket-handle tear on MRI. The presence of "fragment within the intercondylar notch sign" and "the absence of the bow tie sign" may be an indication of a free meniscal fragment. This should be considered during diagnosis.
桶柄状半月板撕裂是半月板损伤的一种特殊类型，在磁共振成像（MRI）上有特定表现。任何类型的撕裂导致半月板附着碎片从半月板移位时，就会引起半月板桶柄状撕裂。磁共振成像（MRI）是半月板损伤最常用的诊断工具。我们报告一例游离内侧半月板碎片病例，其在MRI上表现类似脱位的桶柄状撕裂。“髁间切迹内碎片征”的存在和“蝴蝶结征”的缺失可能提示存在游离半月板碎片。在诊断过程中应考虑到这一点。
