Study of Morphometry of Clavicle in East Indian Population

Abstract

Introduction: The clavicle is a subcutaneous bone most frequently fractured at the junction of medial 2/3rd and lateral 1/3rd of its shaft. The knowledge about the morphometry of clavicle is important for surgeons as well as orthopaedic surgeons. Aim: The aim of this study is to measure the variation of length, medial and lateral angle in east Indian population. Materials and Methods: In this observational cross-sectional study, 54 dry adult clavicle (25 males, 29 females) were collected from the first year medical students of various colleges of West Bengal (east India). The length, medial and lateral angles were measured. The data obtained was tabulated in Microsoft Excel sheet and then transferred to IBM Statistical Package for the Social Sciences (SPSS) version 23. The data was analysed using Independent Sample t-test assuming unequal variances, taking p<0.05 as statistically significant. Results: The average mean length of left sided clavicle was slightly more in both male and female than the right side. But this difference was statistically nonsignificant as p-value was 0.768 (male) and 0.74 (female). In male, the average lateral angle of left side was more than the right side but not so in case of female where the right side was more than the left side. This difference was statistically significant in case of both male (p-value=0.0008), and female (p-value=0.0001). In case of medial angle, it was more in left side in both males and females. The difference was also significant in both males (p-value 0.0001) and females (p-value=0.00001). Conclusion: The present study revealed that the average length of clavicle in case of males are more in right and left side than females. The lateral angle is more for females on right side and more for males on the left side. The medial angle is more for females on both right and left side as compared to males.
