To establish regression models of stature estimation for Sichuan Han female by the measurement of total vertebral column length in the frontal and lateral X-ray films of whole-spine.
The frontal and lateral X-ray films of whole-spine were collected from 200 Sichuan Han females by large flat-panel multi-functional universal radiography and fluoroscopy system. The data and mean values of frontal and lateral total vertebral column length were measured and calculated in all the samples, respectively. The relationship of combined multi-markers and stature were analysed by linear regression analysis, and the mathematical models of stature estimation were established. The data of 30 new samples were selected and inputted for verifying the accuracy of the mathematical models.
The total vertebral column length showed a good correlation with stature, and the mean values of the frontal and lateral X-ray films of total vertebral column length had the highest correlation coefficients. Three established linear regression equation models were statistically significant （<0.05）, and the equation established with lateral total vertebral column length showed the highest accuracy.
The stature estimation by the measurement of total vertebral column length has high accuracy.
通过测量全脊柱正侧位X线片上的总脊柱长度，建立四川汉族女性身高估计的回归模型。
采用大型平板多功能通用X线摄影透视系统，收集200例四川汉族女性的全脊柱正侧位X线片。分别测量并计算所有样本的正侧位总脊柱长度数据及均值。采用线性回归分析方法分析多标记组合与身高的关系，建立身高估计的数学模型。选取30个新样本的数据输入，验证数学模型的准确性。
总脊柱长度与身高呈良好的相关性，正侧位总脊柱长度X线片均值的相关系数最高。建立的3个线性回归方程模型具有统计学意义（<0.05），其中以侧位总脊柱长度建立的方程准确性最高。
通过测量总脊柱长度进行身高估计具有较高的准确性。
