摘要： 目的探讨撕脱性骨折与永存性骨骺、籽骨、副骨的影像学鉴别办法。方法回顾性分析了14个要求重新鉴定是否存在骨折的案例,观察撕脱性骨折的直接、间接征象,并结合其发生机制与永存性骨骺、籽骨及副骨的固有形态、特点等进行对照。结果所选案例中有2例永存性骨骺、3例籽骨、3例副骨均具有骨块边缘钝圆、骨皮质连续、局部软组织未见肿胀以及伤后该骨的连续摄片无明显变化等共同特征。结论正确掌握撕脱性骨折、生理性小骨骺、籽骨及解剖变异的副骨的特点,并综合运用影像学资料是鉴别撕脱性骨折的基本要素。

Abstract: Objective To investigate a method to distinguish avulsion fracture from sesamoid,accessory bone,and permanent osteoepiphyte. Methods Fourteen cases of suspicious avulsion fractures of articular portion of tubular bones were reviewed. Direct/indirect signs and the injury mechanism of avulsion fractures were analyzed and compared with permanent osteoepiphyte,sesamoid and accessory bones for their morphological characteristics. Results There are two cases of permanent osteoepiphytes,three cases of sesamoids,and three cases of accessory bones. These cases were characterized by smooth edges,contiguous bony cortex,without swelling of the surrounding soft tissue or obvious image changes after consecutive radiography. Conclusion It is fundamental in image analysis to distinguish avulsion fracture from physiological small osteoepiphyte,sesamoid bone,and aberrant accessory bone.
