The humerus is the longest and thickest bone of the upper extremity which connects the shoulder to the elbow. Anthropometry estimations are exceptionally valuable to appraise stature and bone length from the remaining skeletons. The age determination above 18 years were evaluated by proximal humerus epiphyses after closure of radius and ulna epiphysis. Humeral morphology is vital in prosthetic replacement of the upper end of the humerus and morphometric analysis of olecranon fossa is vital because olecranon fractures occur in 10% of all upper extremity lesions. The aim of this study is to work out the morphometric analysis of the distal end of humerus and is to compare our study with other populations. The study was performed using 40 dry humerus of left (18) and right sides (22). Morphometric measurements of five different segments of the distal end of humerus were analyzed. The Distance between medial epicondyle to lateral epicondyle (D1), Distance between medial margin of Trochlea and capitulum (D2), Maximum Transverse diameter of Trochlea (D3), Maximum Transverse diameter of olecranon fossa (D4) and Maximum Vertical diameter of olecranon fossa (D5) were measured with the help of vernier calipers. The values were noted separately for right and left sided humerus. Mean, standard deviations were calculated and comparative statistical analysis is employed. There have been significant differences in 40 humerus bones while measuring D1, D2, D3, D4 and D5. The value of D1 and D2 in Right sided humerus is slightly greater than Left sided humerus. The value of D3 in Right side is almost analogous to Left sided humerus. The value of D4 and D5 in the Right side is lesser than the Left sided humerus. Our study supplies the mean values of the distal end of humerus within the South Indian population. The morphometric knowledge is useful in prosthetic sizing and designing of the distal end of humerus. Also, the knowledge of the humerus segment is extremely useful for orthopaedic surgeons, anthropologists and forensic practice.
