Estimation of stature and determination of sex from radial and ulnar bone lengths in a Turkish corpse sample

Abstract

Determination of sex and estimation of stature are important aspects of forensic identification of an unknown individual. In the absence of pelvis the sex is assessed from long bones and cranium as they both provide high accuracy in sexing. The present study is an attempt to assess sex and stature from long bones of the forearm using recently deceased forensic cases in Istanbul, Turkey. The sample is composed of 80 males and 47 females with an average age of 36 and 30 years, respectively. Length measurements from the radius and ulna were obtained by exposing the epiphyseal ends of the long bones in a fashion similar to dry long bones. Discriminant function statistics showed a sex determination accuracy as high as 96%. Regression analysis was used in stature estimation from these two bones. Ideally osteological remains are necessary to make standards for osteological identification. These materials are not always easy to obtain and those available seem to be less ideal when they do not represent a current population. Forensic anthropologists therefore should develop techniques that utilize autopsy remains.
