ABSTRACT
The pelvis has shown to have diversed functions, thus this study is to assess the shape and dimension of the pelvis in a Nigerian populaion. 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. Pelvic Width is the measured breadth between the anterior superior iliac spine to posterior superior iliac spine on one side of the pelvis. Total Pelvic Width is the maximum distance between the outer lips of the iliac crests. Pelvic Height is the measured distance between the most superior part of the iliac crest and the tuberosity of ischium. Data was analyzed statistically (for Descriptive statistics) using SPSS software version 20.0 for windows. Z -Test was used and (p<0.05) was considered significant. The results showed that the mean values of pelvic width for males and females are 112.07±8.75 and 109.18±9.04 (p<0.05. The mean values of pelvic height for Nigerian males and females are 223.43 ± 11.85 and 215.68±12.70 (p<0.05). The mean value of total pelvic width for Nigerian males and females are 297.36±17.40 and 297.75±18.99. The mean values of pelvic index for males and females are 199.52±7.54 and 198.37±16.72. The mean values of total pelvic index for males and females are 75.17±0.74 and 72.70±5.14 (p<0.05). It is crystal clear, that the males have a higher pelvic width and height than the females. The females possess a higher total pelvic width than the males (p>0.05). Which is an indicator that the pelvis is a good estimator of sex for forensic settings with clear demarking points.
