Morphometry of Dry Ossified Left Human Clavicle

Abstract

Background: The clavicle is a modified long bone placed horizontally and subcutaneously at the root of the neck. This bone shows high variability in its shape and size; more frequently than other long bones of the human skeleton. It has its peculiarities with ossification; it is the first bone to start ossification. It is one of the bones of the shoulder girdle in humans and in those mammals, who use their hands for pretensions. It plays an important role in sex determination in humans; length, midclavicular circumference, and rhomboid fossa are principal indicators for sex determination. Objective: To provide osteometric data on clavicles in the Bangladeshi population. Materials and Methods: The present study was a cross-sectional analytical type of study, carried out in the Department of Anatomy, Dhaka Medical College, Dhaka, Bangladesh from January 2022 to December 2022. A total of 120 dry ossified left human clavicles were collected from Dhaka Medical College, Dhaka. Most of the variables were measured with the help of a digital Venire caliper. Results: Out of 120 clavicles 70 were males and 50 were females. The straight length of the clavicle, mid-shaft circumferences, and straight length of the rhomboid fossa were greater in males than females. Conclusion: The clavicle is crucial for determining sex, length, circumference, and rhomboid fossa size which differed significantly between males and females, with males having larger measurements.
