ABSTRACT
Introduction: Height plays a vital role in establishing the identity of an individual. Anatomically, it is a linearcomposite of skull, vertebral column, pelvis and legs and is measured from vertex to foot. Many instances wheredirect measurement of height is impossible, necessitates an alternative methodology.Aim: As height is directly proportional to the length of long bones, my present study aims at deriving a regressionequation between height and percutaneous length of ulna in gender specific south Indian adolescent population.Materials and Methods: A total of 153 subjects (76 male and 77 female) with age span of 20 – 22 years wereincluded in this study. Length of ulna was measured using sliding Vernier caliper and height by standard heightmeasuring instrument for all subjects.Results:The findings of the study indicated significant differences of the ulna length between the genders. Apositive correlation between height and ulna length was observed in both sexes and it was statistically significant.Regression equations for stature estimation were formulated using the ulna lengths for both males and females.Conclusion: The ulna length provides an accurate and reliable means in estimating the height of an individual.The regression formulae proposed in this study will be useful for clinicians, anatomists, archeologists,anthropologists and forensic scientists when such evidence provides the investigator the only opportunity togauge that aspect of an individual’s physical description
ABSTRACT
Introduction: Stature is the natural height and built of a body or person. Stature has been one of the mostimportant factor in the description of the human body characteristics. Various types of parameters are usedwhile estimating stature of human body. Prediction of stature with the help of length of ulna appears to besignificant to forensic Science experts, anthropologists, archeologists and demographers.Aim: The aim of the study was to establish a relationship between the stature of an individual and the length ofulna.Materials and Methods: This study was conducted on 240 medical, paramedical students and staff in age groupof 20-50 of UP University of Medical Sciences, Saifai, Etawah, UP, India. Length of ulna of subjects was measuredby Vernier caliper in similar anatomical position and at fixed time to avoid diurnal variation. Correlation andRegression analysis were carried out to establish relationship of length of ulna with the height.Results: Statistical significant positive correlations between length of right ulna and the height for male (r=0.6784;p-value<0.00001) and for female (r=0.6617; p-value<0.00001), and between length of left ulna and the height formale (r=0.6828; p-value<0.00001) and for female (r=0.6275; p-value<0.00001) were observed respectively.Regression equations for stature were also derived.Conclusion: The finding of study suggest that length of both right and left ulna can be successfully used for staturereconstruction.
ABSTRACT
Background: Estimation of stature plays an important role in medico-legal cases in the identification of unknownbodies, parts of bodies or even skeletal remains. There exists a strong relationship between stature and dimensionsof different body parts, particularly bone lengths, which forms the basis for stature estimation. Ulna bone isused as it is subcutaneous and hence surface landmarks such as olecranon and styloid process are easilyidentifiable and can be used for measurements.Materials and Methods: The present study was carried out on 300 medical students of Marathwada region of Dr.Shankarrao Chavan Government Medical College, Nanded, Maharashtra. Height and percutaneous ulna lengthwere recorded for each subject.Result: Mean height of male subjects is 171.99 ± 6.04. Mean of length of right and left ulna in male subjects are26.92 ± 1.30 and 26.85 ± 1.32 respectively. The mean height of female subjects is 165.49 ± 3.18. Mean of lengthof right and left ulna in female subjects are 21.77 ± 0.93 and 21.69 ± 0.88 respectively. The correlation of staturewith ulnar length is 0.66 in males and 0.70 in females, which are positive and statistically highly significant (P< 0.01).Conclusion: In Marathwada region of Maharashtra mean height and length of ulna is more in males than infemales and it is statistically significant. Simple linear regression equation so far derived can be used if eitherof the measurement of length of ulna or total height is known, the other can be calculated. This fact will be ofpractical use in Medico Legal investigations and in Anthropometry.
