Abstract / Description of output

Sex estimation is vital for biological profiling, thus qualitative and quantitative methods have been developed for every skeletal part in humans. However, somehow the radius has been neglected. This study aims to develop a sex estimation method on radiographs of the radius applicable in situations when classical osteometry cannot be applied. A total of 103 left radii were used in this study. Three classical measurements (maximum length, head diameter and distal breadth) were taken on the dry bones. Digital radiographs of the same radii were taken using a portable X-ray machine (Technix TCA 4R PLUS). Eight landmarks are selected on the radiograph of the proximal and six on the radiograph of the distal radius, generating in total 43 linear distances. ANOVA detected three osteometric and 24 radiometric variables that differed significantly between males and females (p<0.05). Classical osteometry resulted in up to 91% classification accuracy while the best multivariate formula of the radiometric method gave 88% correct classification. The study proposes a rapid and inexpensive alternative method for sex screening based on digital radiographs of the radius, a method that could be particularly advantageous in cases of mass disasters with numerous mutilated and/or burnt bodies where maceration is not an option.
