Acetabulum diameter, Acetabulopubic index, Sex determination, South Indian population


The capability of determination of gender from unknown human skeletal remains is indispensable and
the techniques to find out this from different bones of human skeletal remains have been researched
tremendously. Several investigators have asserted the necessity for population specific statistical data for
methods that are dependent on specific measurements as there exist ample variations in body size among
diverse ethnic populations. Most reliable bone exhibiting sexual dimorphism in human body is the pelvis and
we have chosen it for derivation of population and sex specific data with respect to diameter of acetabulum
and acetabulopubic index. 72 adult, dry innominate hip bones without any morphological deformities and
defects (38 of male and 34 of female sex) belonging to South Indian population were carefully studied with
respect to diameter of Right acetabulum and acetabulopubic index derived from the maximum distance
between pubis symphysis and the anterior rim of acetabulum i.e. cotylopubic length or acetabulum-pubis
symphysis length. All measurements were accurately taken with the aid of digital Vernier caliper and
results were analyzed by means of SPSS software version 26 and the results including the demarking point,
standard deviation, sectioning point etc. were found to be statistically significant and therefore acetabulum
diameter and acetabulopubic index can be authentically applied for sex determination from dry adult hip
bones belonging to the South Indian population. From the analysis of demarking point, AP index of >94.13
identified 73.84% of male sex and <87.15 identified 84.97% of females and therefore AP index can definitely
be considered as the positive and decisive indicator for sex determination from adult hip bones.
