A model for stature estimation and sex prediction using percutaneous ulnar and radial lengths in autopsied adult Egyptians

Abstract

Identification of unknown cadavers by constructing a biological profile from their skeletal remains is one of the main aims of any forensic pathologist. Many researches tend to focus on the formulation of sex estimation standards using measurements taken from long bones of the appendicular skeleton, rather than the traditionally favored skeletal remains namely; pelvis and cranium. But yet, there are no organized studies are yet available for gender and height estimation in adult Egyptians. Objective: To formulate a model for stature construction and sex prediction the Maximal Radial and ulnar lengths in adult Egyptians. Materials and methods: Maximal lengths of the radius and ulna bones, taken from adult Egyptian cadavers presented to Forensic medicine mortuary for pathological or medico-legal reasons during the period from the start of January 2014 till the end of December 2014 were recorded, studied and statistically analyzed. Ethical pre-study acceptance was ensured and guidelines were respected. No conflict of interest existed for all researchers. Results: Maximal Radial and ulnar lengths in 122 Egyptian cadavers (85 males and 37 females) in the age range between 18 and 65 years old were statistically analyzed. Mathematical regression formulae, were constructed to determine the stature in the studied subjects. The accuracy of both radial and ulnar lengths in sex determination was 98%, while it was 97.5%, and 92.3% consecutively, in case of using radial or ulnar lengths alone. Conclusion: Radius and ulna bones, can help in sex prediction as well as stature estimation with high accuracy in unknown cadavers or remains.
