Resumen
Biometrics and forensic osteology play a significant role in human identification, as the morphological uniqueness of every individual enables the differentiation and recognition of skeletal remains. Through meticulous analysis of human remains, it is possible to determine key demographic attributes such as stature, a significant parameter in the forensic identification process. This information is of practical relevance for the identification of individuals in contexts such as disasters, vehicular accidents, terrorist attacks, armed conflicts, and forensic investigations. The objective of this study was to determine the correlation between the hand's middle finger length and stature in a group of Chilean students. A total of 211 students of both sexes from La Araucanía region, Chile, participated in the study. After obtaining informed consent to participate voluntarily in the study, each individual underwent a general anthropometric examination, followed by a specific assessment of the length of the middle finger (MFL) of both hands. The results of the multiple linear regression analysis indicated a significant prediction of stature using the length of the right (R-MFL) and left (L-MFL) middle fingers, F (2, 207) = 79.80, p < 0.001. The equations for estimating stature based on the length of the middle fingers are as follows: for R-MFL, Stature = 91.265 + (8.092 × R-MFL), and for L-MFL, Stature = 83.967 + (8.889 × L-MF). Based on these results, it was found that the length of the middle finger of both hands is predictive of stature. © 2024, Universidad de la Frontera. All rights reserved.
