ABSTRACT
The human pelvis has shown to hold varying degree of functions, thus this study is aimed at evaluating the role of pubic synphysis on sex estimation. Convenient sampling was done and a total of 1500 Anterior posterior pelvic radiographs were measured (703 males and 797 females between ages 25-45years). Samples were collected from Radiology Department of the University of Port Harcourt Teaching Hospital (UPTH), Braithwaite Memorial Hospital (BMH) Port Harcourt, Federal Medical Center (FMC) Yenagoa, Niger Delta University Teaching Hospital (NDUTH) Okolobiri Bayelsa State, University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu State, National Orthopedic Hospital Igbobi Lagos, University of Abuja Teaching Hospital (UATH) Gwagwalada, FCT, Nigeria. Two horizontal lines were drawn at each pubic rami and the measured distance between them is the width of pubic synphysis. Two vertical lines were drawn one at the superior part of the pubic rami while the other at the inferior parts the rami. The distance between the two lines is the height of pubic symphysis. The results showed that the pubic symphyseal width for males and females are 3.97±0.71 and 3.96±0.89. The pubic symphyseal height for males and females are 28.53±3.53 and 25.88±3.77 (p<0.05) thus sexual dimorphism exist. The demarking points were >37.19 male and <17.94 female. Sex could be ascertained of 2% male and 4% female.
Keywords: Sexual Dimorphism, Demarking Points.
