Abstract
ABSTRACT
Background
Determining the sex of deceased is easy when a complete skeleton is available for
examination. On the whole, the bones are heavier, larger and markings of muscular
attachments are more pronounced in the male than in the female.
Objective
The purpose of this study was attempted to evolve an easily applied formula
to enable the assessment of sex in an unknown clavicles and to know about
comparative differences between the right and left clavicles, from certain metrical
parameters.
Methods
The study was an observational, cross-sectional and descriptive in nature. The
present study was conducted on 257 adult clavicles out of which, 135 were of the
right side and 122 of left side. The maximum length of the clavicle (in mm) was
taken.
Results
The length of the right clavicles varies from 108 mm to 178 mm with an average of
143.21 mm ±11.13 mm S.D. The length of the left clavicles varies from 111mm to
181 mm with an average 145.53 mm ±11.04 mm S.D. It has been observed that the
left clavicle was longer than the right clavicle by 2.32 mm. There was no such single
character which can determine the sex of all clavicles. Depending on the length
alone, the sex can be decided in 13.33% male and 4.44% female right clavicles and
16.39% male and 9.83% female bones if the left clavicle is considered.
Conclusion
The left clavicle was longer than the right clavicle. The determination of sex from
the clavicle has a great medico legal significance to the toxicologists. It also helps
the anthropologists in their study of evolution of mankind and migration of races.
