颈椎外伤儿童中,第3颈椎楔形变是正常变异还是压缩骨折?针对此问题作者对481例病儿C_(3-7)椎体形态进行了研究。作者回顾性地分析了病例颈椎的侧位照片。将椎体形态分为四型:Ⅰ椎体呈卵圆形或发育不全;Ⅱ椎体前上角呈圆形;Ⅲ椎体前部逐渐变窄呈楔形;Ⅳ发育完全的矩形椎体。病例分为4个年龄组:0～3岁(160例);4～7岁 Among the children with cervical trauma, is the third cervical vertebrae wedge degeneration normal compression or compression fractures? The authors of this study investigated the morphology of C 3-7 vertebral bodies in 481 sick children. The authors retrospectively analyzed the lateral cervical spine photos. The vertebral body morphology was divided into four types: Ⅰ vertebral oval or hypoplasia; Ⅱ vertebral anterior horn was round; Ⅲ anterior vertebra gradually narrowed to wedge shape; Ⅳ fully developed rectangular vertebral body. Cases were divided into 4 age groups: 0 to 3 years old (160 cases); 4 to 7 years old
