Abstract

Background: Identification is the determination of the individuality of a person based on certain physical
characteristics. The clavicle is one of the bones which is less explored but has drawn considerable interest
in this field, particularly concerning sexual dimorphism. Aim& Objectives: The present study evaluates the
existence of sexual dimorphism based on various morphometric parameters of the clavicle in a dry sample
and identifies the best predictor amongst these. Materials & Methodology: The study was conducted in the
mortuary of the Department of Forensic Medicine, Gandhi Medical College, Bhopal on 100 random cases
(50 males;50 females) in which medico-legal post-mortem examination was done. After taking due consent,
clavicle bone of deceased between25 to 60 years age group were collected during the autopsy, dried and
then examined for the study. Measurements were carried out and statistically compared to evaluate sexual
dimorphism. The studied parameters include Maximum length of clavicle, Breadth of sternal end, Breadth
and Length of acromial end, Area of acromial surface and Mid clavicular circumference. Observations &
Results: Amongst all the parameters, Maximum length of clavicle and Mid clavicular circumference are
the most reliable parameters for sexual dimorphism with 81% accuracy rate when considered together. If
all the morphometric parameters are taken together then the sex can be determined with 87% accuracy.
Conclusion: Sexual dimorphism exists in clavicle and all the measured parameters contribute to different
sex individually and with 87% accuracy when taken together. The derived discriminant function equations
can be used to correctly assign the bones to the proper sex.
