Abstract :
Background: Determination of sex from skeletal remains is of
paramount importance for Forensic Experts for identification
of the deceased. The task becomes more difficult when only a
single bone is available. Though most bones exhibit clear cut
sexual variation in morphology but to determine sex with
100% accuracy, one has to use metric measurements to study
various indices. These indices exhibit significant variation in
range according ethnicity & geographic location, hence is
suggested to arrive at Demarking Point (D.P.) for these
parameters which greatly help in sexing of a bone. Sacrum has
been considered amongst ideal bones to determine sex of
individual because of its functional morphological variation in
both sexes by virtue of its contribution to pelvis. Numerous
indices have been reported to determine sex of sacra but of it
none have proved to effectively & singularly differentiate sex.
Hence is advised to not rely on a single index but use
maximum possible indices to determine sex of sacrum. Also to
be taken in consideration is fact that values of these indices so
is their D.P. varies according to geographical location. Hence
studies such as this are carried out to calculate anthrometric
data regarding various measurements & indices for a particular
region.
Method: 150 sacra of known sex from Tamil Nadu of South
India were studied for metrical parameters for determination of
sex. Efforts were made to find Demarking point for each
parameter and then compared with similar studies.
Results: It was evident from present study that sacral index is
the most important parameter as far as the sex determination of
sacrum is concerned as it could singularly identify 56% male
and 78% female bones. Sacral index for population under
study was observed to be 99.21 for males and 119.94 for
females.
Conclusion: The present study highlight importance of certain
parameters like sacral index while also demonstrating
insignificance other parameters, but basic fact remains that as
far as the sex determination of sacrum is concerned no single
parameter could identify sex in 100% of the bones and hence,
it can be concluded that for sex determination of the sacrum
with 100% accuracy is possible only when maximum number
of parameters are taken into consideration.
