Abstract

The aim of this study was to use the Ischiopubic index to explore the sex differences in the pelvis betweenthe male and female bones. The pelvis is characterized by sexually dimorphic features and thus it can beused for sex determination while establishing the biological profile in unknown skeletal remains. In thisstudy we have assessed the sex prediction potential of the Ischiopubic index using 72 dry innominate hipbones (38 male and 34 female) belonging to South Indian population. The lengths of the pubis and ischiumwere measured in these bones and the Ischiopubic index was calculated as per Washburn’s formula. TheIschiopubic index was calculated to be 85.46 ± 3.63 mm. in males (Range 74.15 - 95.28 mm.) and 97.75 ±4.10 mm. in females (Range 89.56 - 116.37 mm.). Application of the Student’s t test showed that there wasa statistically significant difference in the Ischiopubic index between the male and female pelvic bones witha p <0.001.

Abstract

Establishment of the identity of an individual from dismembered remains or skeletal remains is a commonproblem encountered by the Forensic Pathologist and can be a challenging task. In addition to age and sex,stature is an anthropological parameter that is indispensable in establishing the identity of an individual.In the present study, we have analyzed the relationship between stature and percutaneous Tibial lengths(PCTL) and derived a regression equation for a specific population. The parameters namely, the statureand percutaneous Tibial lengths (PCTL) of both lower limbs were measured in 115 females belonging toTamil population and recorded. The subjects were in the age group of 21-30 years. Analysis of the resultsinvolved the use of the Pearson’s correlation to derive the relationship between the parameters and establishthe dependence of the stature on the length of the left and right Tibia respectively in the study subjects. Theresults from this present study attest to the utility of the percutaneous Tibial lengths (PCTL) in determinationof the stature in females belonging to the Tamil population.

Abstract

The capability of determination of gender from unknown human skeletal remains is indispensable andthe techniques to find out this from different bones of human skeletal remains have been researchedtremendously. Several investigators have asserted the necessity for population specific statistical data formethods that are dependent on specific measurements as there exist ample variations in body size amongdiverse ethnic populations. Most reliable bone exhibiting sexual dimorphism in human body is the pelvis andwe have chosen it for derivation of population and sex specific data with respect to diameter of acetabulumand acetabulopubic index. 72 adult, dry innominate hip bones without any morphological deformities anddefects (38 of male and 34 of female sex) belonging to South Indian population were carefully studied withrespect to diameter of Right acetabulum and acetabulopubic index derived from the maximum distancebetween pubis symphysis and the anterior rim of acetabulum i.e. cotylopubic length or acetabulum-pubissymphysis length. All measurements were accurately taken with the aid of digital Vernier caliper andresults 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 acetabulumdiameter and acetabulopubic index can be authentically applied for sex determination from dry adult hipbones belonging to the South Indian population. From the analysis of demarking point, AP index of >94.13identified 73.84% of male sex and <87.15 identified 84.97% of females and therefore AP index can definitelybe considered as the positive and decisive indicator for sex determination from adult hip bones.
