Introduction: The aim was to obtain the dimensions of the distal fragments of humerus bone, and the objective was to derive the formulae of regression, which will assist us to estimate the humeral length. Material and Methods: In this cadaveric research, 166 adult dried humeri from the department of anatomy were utilized. The measurements were performed by using the osteometric board and digital Vernier caliper. The seven distal humeral fragments were measured. Results: We were able to associate the dimensions of the distal humeral fragments with the humeral length (P = 0.00). The distances between the radial summit of the capitulum to the ulnar part of the medial epicondyle (right side Pearson's coefficient, 0.70 and left side, 0.78) and the radial side of the lateral condyle to the ulnar most side of the medial epicondyle (right side Pearson's coefficient, 0.69 and left side, 0.77) were the finest parameters, which can predict the length of humerus. Discussion and Conclusion: The regression calculations can be of help in estimating the humeral length. Such equations could be utilized during the examinations of forensic cases, where the estimation of height of an individual is required to be predicted, when only a few distal fragments of humerus are available. The figures of this investigation can also help in anthropology and archaeological research.
