摘　　要：[目的]研究胸椎后凸与性别、年龄、椎体和椎间盘形态的关系。[方法]回顾性研究、收集61例样本的性别、年龄资料和胸椎MRI片。在计算机上测量椎体、椎间盘前后缘的高度和Cobbs角,以椎体和椎间盘前后缘的高度比值代表椎体和椎间盘的形态,Cobbs角代表胸椎后凸。通过Pearsons相关分析和逐步回归分析研究他们之间的相关性。[结果]椎体形态与胸椎后凸的相关性比较大,相对来说椎间盘与胸椎后凸的相关性则比较小。女性81%的胸椎后凸与椎体和椎间盘的形态有关。男性72%的胸椎生理性后凸与椎体和椎间盘的形态有关。[结论]正常胸椎后凸是由椎体和椎间盘的形态共同决定的,特别是女性胸椎后凸与椎体和椎间盘形态的关系更加密切。[Objective] To examine the relationship of thoracic kyphosis with gender, age, shape of thoracic vertebral bodies and intervertebral discs. [Method] The gender, age data and MR films of Thoracic spines of 61 cases were collected in a retrospective study. The MR films were scanned into computer. Vertebral and disc morphology, as represented by antero-posterior height ratios, were quantified in computer. Kyphosis was indicated by the Cobb angle. Pearson＇s correlation analysis and stepwise regression were applied to examine relationship between them. [Result] Vertebral morphology was highly related with thoracic curvature, while a poorer association was noted to disc morphology. The combined infuence of both morphology of vertebral body and intervertebral disc accounted for the variability in kyphosis in 81% female, and 72% in male. [Conclusion] The normal kyphosis of the thoracic spine is determined by the morphological state of both the vertebral bodies and intervertebral discs, especially in female.
