Metrical parameters for approximation of height from superior extremity long bones in humans

Abstract

This study entitled “Metrical parameters for approximation of height from superior extremity long bones in humans” was worked out in the Anatomy Department, GMC, Aurangabad. Students belonging to second year of M.B.B.S, B.D.S, and B.sc Nursing with other non-medico members of the department were included in the study. The age range of the study subjects was between 20 to 50 years including both males and females totaling 500 in number. The study focused on devising a linear regression equivalence to estimate height from the length of arm and forearm bones (viz. humerus, radius and ulna). The stature or height was measured with the help of an anthropometer from crown to heel, length of humerus from humeral head to the farthest point on trochlea, length of ulna from the tip of olecranon process to the distal point of its styloid process, length of radius from the most proximal margin of the head to the distal point of its styloid process. All these measurements were taken with the help of spreading calipers. Correlation coefficient (r) for length of long bones with stature was 0.565 for male humerus, 0.4699 for female humerus, 0.5434 for male radius, 0.4987 for female radius, 0.6398 for male ulna and 0.5637 for female ulna. ‘t’ test applied for testing the statistical significance of the obtained values was found to be significant. The regression equations for approximation of stature were formulated using length of humerus, radius and ulna. Keywords: Stature estimation, Humerus, Radius, Ulna.
