Evaluation of Asymmetry between the Maximum Length of Right and Left Humerus of Bangladeshi Population.

The humerus is the typical long bone of the superior extremity. It consists of three parts- upper end, lower end and intervening shaft. The aim of this study was to evaluation of the asymmetry of maximum length between the right and left-sided humerus. For the study 100 human humerus, 43 on the right side and 57 on the left side were elaborated. Samples were selected through the purposive sampling technique for this cross-sectional descriptive study in the Department of Anatomy, Mymensingh Medical College, Mymensingh, Bangladesh from July 2021 to June 2022. Any damaged, unossified bones or fractured bones were excluded. Data were tabulated and statistically analyzed using Microsoft Excel and SPSS software. In this study, the mean±SD maximum length of the humerus was 304.139±17.652 mm and 300.42±20.779 mm on the right and left sides respectively. These studies confirmed that the right-sided humeral dimension was more prominent than the left side. So, the asymmetry between the maximum length of right and left humerus is established. We hope that this study of the maximum length of humerus among the Bangladeshi population may be very helpful for anatomists, police, forensic experts, anthropologists and radiologists.
