| 摘 要： | 目的探讨青少年特发性颈椎后凸畸形的影像学特征。方法2010年1月～2012年1月共有16例特发性颈椎后凸畸形患者在我院进行诊断治疗，分析其影像学资料，测量后切线角度和Cobb’s角度，并计算曲度指数和后凸指数。结果Cobb’s平均角度（52．6±16．3）。，后凸节段后切线平均角度（53．8±17．4）°，两种测量结果差异无统计学意义（P〉0．05），具有明显的相关性（r=0．82，P〈0．01）。C2-7Cobb’s角度平均为（34．1±15．5）°，后切线角度为（35．8±14．2）°。KI和CI与Cobb’s角度及后切线角度均呈正相关。结论青少年特发性颈椎后凸的影像学特点：后凸顶点位多于椎体后上缘，C4多见，CI和KI与Cobb’s角和后切线角正相关。

| Abstract: | Objective To discuss the imaging features of adolescent idiopathic cervical kyphosis.Methods Image data of 16 cases with adolescent idiopathic cervical kyphosis from Jan 2010 to Jan 2012 were analyzed.The posterior tangent angle and Cobb angle of kyphosis were measured;CI and KI were calculated.Results Cobb angle of kyphosis was(52.6±16.3)°,posterior tangent angle of kyphosis was(53.8±17.4)°.There was no significant difference between two methods(P > 0.05),and there were correlation between two methods(r = 0.82,P < 0.01).Cobb angle of C2-7 was(34.1±15.5)°,posterior tangent angle of C2-7 was(35.8±14.2)°.CI and KI showed significant positive correlation with posterior tangent angle and Cobb angle.Conclusion Imaging features of adolescent idiopathic cervical kyphosis: most of kyphosis apex locates at the posterosuperior edge of vertebrae,CI and KI show significant positive correlation with posterior tangent angle and Cobb angle. |
