Stature estimation in Iranian population from x-ray measurements of femur and tibia bones

Introduction

Stature estimation of human skeletal remains is important in medico-legal and forensic anthropology to personal identification. Several investigations have been carried out to estimating the height using the long bones. This study aimed was prediction the height of Iranian people based on the maximum length of femur and tibia by application of X-Ray method.

Methods

This cross-sectional study was conducted in the radiology department of Baqiyatallah Hospital of Tehran, Iran between 2017 and 2018. The number of 166 adult women and men were investigated during the study period. Maximum lengths of the tibia and femur bones were measured on the X-Ray images. In the following, the data were analyzed by SPSS (ver. 22).

Results

The results showed that there was a correlation between the stature and both of the femur and tibia lengths in the men and women (P-value <0.001). However, the highest values of correlation coefficient (R) were detected between the stature and lengths of the men's tibia (R = 0.838) and femur (R = 0.815) and lowest values were identified in the tibia (R = 0.467) and femur(R = 0.431) lengths of the women, respectively. The lowest value for standard error of the estimation (SEE) and the highest value for the coefficient of determination (R²) were observed in multiple regression equation derived from the lengths of the men's femur and tibia (R²=0.736 and SEE=5.64).

Conclusion

Data confirmed that lengths of the tibia and femur of the men yield the best results in terms of the accuracy of the stature estimation in Iranian population.
