Stature Estimation for Sichuan Han Female Based on Whole-spine X-ray Photo-graphy / 法医学杂志

ABSTRACT

Objective 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. Methods The frontal and lateral X-ray films of whole-spine were collected from 200 Sichuan Han fe-males 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. Results 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(P＜0.05), and the equa-tion established with lateral total vertebral column length showed the highest accuracy. Conclusion The stature estimation by the measurement of total vertebral column length has high accuracy.
