Background: The humerus is the largest bone of the upper limb. Morphometry of the humerus is important for the identification of unknown bodies,and the estimation of height, age, and gender in forensic science. Morphometry of the distal end of the humerus can assist in reconstructive surgeries through implants as orthopedic surgeons face difficulty in fixing complex fractures. Aim and objectives: The present study aims to provide morphometry of the distal end of the humerus and its length Methodology: Eight morphometric parameters were evaluated from 70 dry adult humeral bones using measuring tape and vernier caliper in units of mm. The length of the humerusis 306.55±16.45mm and 303.20±11.12mm on right and left side. The transverse distance between the medial and lateral epicondyle on the right side of the humerus was 59.47±2.53mmand 57.57±3.53mm on the right and left side. The average transverse distance between the capitulumand medial flange of trochlea was 42.27±1.99mm and 42.48±2.42mm on right and left side. Themaximum transverse distance from the medial epicondyle to the capitulumwas 56.60±2.71mm and 53.95±3.96mm on right and left side. The horizontal diameter of the trochlea was 23.27±1.79mm and 22.80±1.74mm on right and left side. The anteroposterior diameter of the trochlea at the middle was 16.57±1.55mm and 16.30±1.24mm on right and left side. The length of the medial flange of the trochlea was23.23±1.67mm and 22.67±1.70mm on right and left side. The length of the lateral flange of the trochlea18.17±1.72mm and 17.17±1.28mm on right and left side. Conclusion: When compared with the Turkish and Brazilian populations there wasa decrease in all parameters but when compared with the Indian population there was a little bit of difference or some measurements werethe same.
