摘　　要：目的探讨不同部位的永存骨骺与撕脱骨折的影像学特点及鉴别方法。方法分析经临床及影像学证实的永存骨骺20例及撕脱骨折30例影像特征。结果 20例永存骨骺中,发生在第五跖骨基底部8例,椎体前缘9例,尺骨茎突3例,均具有游离骨块,其斜边与骨干缺损面对应,呈平行直线型,轮廓光整,皮质连续,局部软组织无异常改变等特征,撕脱骨折30例,尺骨骨折9例,腰椎10例,第五跖骨骨折11例,骨块多成游离骨块或部分游离,骨折线与骨干多成横行或斜行,骨皮质欠连续,软组织水肿、积液或积血CT、MRI异常改变等。结论综合运用DR、CT、MRI检查来鉴别永存骨骺与撕脱骨折,最大程度减少误诊、漏诊,以免延误治疗。Objective To explore different parts of perpetuating epiphysis and radiological characteristics and identi- fication. Methods A retrospective analysis of 20 cases of persistent epiphysis by clinical and radiographic evidence of and 30 cases of avulsion fracture image features, the mechanisms of comparison. Results 20 cases forever epiphysis in 8 cases occurred in the base of the fifth metatarsal, 9 cases of vertebral, ulnar styloid 3cases, all with free bone, and the back- bone of its hypotenuse face should defect, was parallel to the straight line type, contour finishing, leather continuous, no ab- normal changes in soft tissue and other features, 30 cases of avulsion fracture of the ulna 9 cases, 10 cases of lumbar fifth metatarsal 11 cases, more than a free bone or bone part of the free, the fracture line multi backbone into the transverse or oblique, cortical bone due to continuous, soft tissue edema, fluid or blood CT, MRI abnormalities and changes. Conclu- sion The comprehensive use of DR, CT, MRI tests to identify persistent epiphysis and avulsion fracture, the maximum ex- tent to reduce misdiagnosis and missed diagnosis, so as not to delay treatment.
