摘　　要：目的　评价C2 肥大征在平片中的诊断价值。方法　回顾分析经X线平片、CT检查及部分手术证实C2 骨折 3 7例 ,男2 9例 ,女 8例 ,平均年龄 3 8.6岁。外伤后全部摄取常规X线正侧位片 ,11例行CT平扫 ,2 7例手术探查。结果　C2 肥大征出现率为 5 3 .13 % ,表现为常规颈椎侧位片上C2 椎体前、后缘之间的距离与C3 椎体相比明显增加 ,最大相差宽度 11mm ,最小为 2 .3mm ,平均 4.3mm。有的伴有骨折线及椎前软组织肿胀。结论　C2 肥大征为C2 椎体骨折的主要放射学表现。Objective To evaluate the diagnostic value of the C 2 “hypertrophic sign” in the axis fracture.Methods 37 cases with C 2 fracture confirmed by radiography,CT and operation partly retrospectively analysed,there were 29 men and 8 woman.After trauma all cases were examined by X-ray and 11 cases by CT scan.27 cases underwent operation.Results The incidence rate of the C 2 “hypertrophic sign” was 53.13%.This sign characterized by the distance increased between the anterior and posterior of the axis on the lateral conventional radiography compared with that of C 3 vertebrae.The maximal increasing distance was 11 mm and minimal one was 2.3 mm with average 4.3 mm.Fracture line and swollen soft tissue in front of the vertebra were showed in some cases.Conclusion The C 2 “hypertrophic sign” is main radiographic sign of C2 fracture.
