Obstetric Dimensions of South Indian Females Analyzed Using Reconstructed Computed Tomography Images – a Pilot Study

The human pelvic dimorphism makes it significant for anatomical, anthropological and forensic investigations. The normal pelvic shape may vary considerably in different races and regions. Surprisingly, very few studies are reported from the Indian population on female pelvis measurements and almost nil in peninsular India. Thus, a study using state-of-art technology (CT) on live subjects (especially in this region) is warranted. The present study analyzed normal female pelves in and around Chennai, India, to determine the reproductive and obstetric challenges. Comparing the anatomical dimensions of women in age groups of 25-35 and 35-45. Analyses indicated that the age of the subjects at the time of measurement would be an important consideration before utilizing pelvic data for a particular application. This study forms a report on anthropometric measurements of adult female pelvis from the south Indian population through CT imaging as a tool for acquiring data from live samples. This study compared the anatomical dimensions of the pelvic bone in modern-day women with reference to two age groups, i.e., 25-35 and 35-45. The data indicate a change in pelvic measurements between these two age groups from the same geographical region, though it is not statistically significant. This indicates the possibility of slight degree of variability during ageing, which could be progressive.
