Stature estimation measuring per-cutaneous length of ulna in living subjects

Abstract

Background: Estimation of stature from bones play an important role in identifying unknown bodies, parts of bodies or skeletal remains. Multiple anthropometric techniques have been used to estimate stature from skeletal remains by anthropologists, anatomists & forensic experts. Since olecranon process and styloid process of ulna are easily felt through the skin, it becomes easy to measure the length of the bone. Objectives: This study was carried out to investigate the relationship between stature and ulna length and to derive a regression formula between the ulna length and height of an individual. Materials and Methods: 300 subjects (150 males & 150 females) aged between 21 and 25 years were included in this study. Measurements of ulna length were taken by using Dividing Calipers and the height was recorded using Stature meter. The data was subjected for statistical analysis using SPSS software. Results: A positive correlation between height and ulna length was observed in both sexes and it was statistically significant. Regression equation for stature estimation was formulated using the ulna length for both sexes. Conclusion: Since simple and easily applicable methods are involved in the determination of stature, it is widely used. The present study thus helps in establishing identity of an individual when only some remains of the body are found as in mass disasters, bomb explosions and accidents.
