Prediction of Stature from Index Finger Length in South Karnataka Population: A First Radiographic Study

Abstract

Context: The “big four” components of biological profile are age, sex, race, and stature. Stature estimation is considered as one of the most important biological profiles for identification of an individual. Aims: We aimed to estimate stature from index finger length (IFL) clinically and also radiographically in South Indian population. Subjects and Methods: A cross-sectional sample of 100 patients was randomly selected from patients who visited the Department of Oral Medicine and Radiology in our institution. Stature of the participants was measured using a height chart ruler. IFL was measured clinically using digital calipers. Handwrist radiographs of the left hand were obtained using the KODAK 8000C Panoramic and Cephalometric System. Radiographic measurements were taken from the line joining the metacarpophalangeal joint to the distal point on the distal phalange of the index finger done using Windows Trophy DICOM software. Statistical Analysis Used: Data were subjected to logistic regression analysis. Results: Significant correlation was found between IFL and stature both clinically and radiographically. Conclusions: The use of IFL can be recommended to predict stature. Even if the soft tissues undergo putrefaction, the radiographs can help in assessing the stature of the individual and can provide an advantage of time in comparison to estimation of stature clinically.
