Abstract:

目的评价多排螺旋CT(MDCT)对少见类型寰椎骨折分型诊断的价值。方法回顾性分析15例少见类型寰椎骨折患者的临床及MDCT检查资料,总结其临床特点及MDCT影像学表现。结果15例中,寰椎前弓骺离骨折4例,寰枕融合畸形并寰椎骨折6例,寰椎前结节骨折2例,寰椎前弓水平状骨折2例,寰椎前后弓不连并前弓骨折1例。15例中合并枕骨髁骨折Ⅲ型1例,齿状突骨折Ⅱ型2例,齿状突骨折Ⅲ型2例,枢椎多发骨折1例,下颈椎骨折3例,颌面部骨折1例。伴有寰枢椎脱位3例,颈2~3椎体融合畸形1例。结论应用MDCT对少见类型寰椎骨折进行检查并结合多种方法后重组,可以明确少见寰椎骨折类型及合并症的发生情况,为临床提供更多的影像信息,MDCT可做为少见类型寰椎骨折影像学评价的最优检查方法。
