“…Among the 17 articles, 9 were performed among Indian populations, 3 among European populations, 2 among American populations, 2 among African populations and 1 in a Korean population. ITC was measured in Indian (NATH and PRABHA, 1999;PARMAR, SHAH, GODA et al, 2015;SINGH, NAIR, ANJANKAR et al, 2013;UMESH BABU, SADASHIV and KIRAN, 2013) and European populations (GIDNA and DOMÍNGUEZ-RODRIGO, 2013), and it was higher in Indian populations (0.21-0.67) compared to European populations (0.20). If compared between male and female individuals, the values of 'r' for ITC were approximately similar.…”

Introduction: In a forensic case with availability of femoral fragments, estimation of the total femoral length of the available segment is one of the steps used for estimating an inidividual's stature. This estimation will be more accurate if the segment has a high coefficient of correlation with the total length of the femur. This article reviews the coefficients of correlation of different segmental measurements with femur length. Materials and Methods: Seventeen articles were selected from PubMed, Google Scholar and other public research sharing sites. Articles with coefficients of correlation of segmental measurements with the total length of the femur were included in the study. Results and Discussion: Among the 17 articles, two were related to measurement of the proximal part of the femur only, one was concerned with femoral shaft measurement only, 7 focus on the distal part only, 3 concerned both proximal and distal parts, and 4 articles included all parts of the femur. Sample sizes varied from 50 to 2388 femur bones. The value of the coefficient of correlation ('r') was found to vary with respect to gender and nationality. The value of 'r' for several width measurements of the segments had a higher correlation among females compared to male individuals. Conclusion: Though segment 1 of the proximal part, segment 3 of the shaft, and the epicondylar and bicondylar breadths of the distal part of the femur are highly correlated with the total length of femur, an investigator should also consider of gender, race, ethnicity and environmental factors when choosing the femur segment that has the highest value of 'r'.

BACKGROUNDThe stature of an individual is used to establish the identity of a person medicolegally. The stature is calculated from the length of long bones. This study is an effort to derive regression equations for the reconstruction of length of femur from its fragments. MATERIALS AND METHODSThis is a descriptive study using hundred and twenty-one dry femurs from Department of Anatomy, Govt. Medical College, Thiruvananthapuram. Length of femur and the dimensions of its proximal segments were measured using osteometric board and Vernier callipers respectively. RESULTSAll the five parameters of the proximal segment show significant relation with length of femur (p value < 0.001) of which intertrochanteric distance (EF) shows maximum correlation. Regression equations for estimating femoral length from the length of proximal fragments were derived by linear regression analysis. CONCLUSIONRegression equations derived in this study are helpful to estimate the stature in medicolegal investigations and in anthropometry. BACKGROUNDThe stature of an individual is used to establish the identity of a person medicolegally. The stature is calculated from the length of long bones. Length of long bones of lower limb particularly of femur and tibia has a direct correlation to the height of an individual. Damage to long bones is common and in such cases reconstruction of height of the body is very difficult. For the identification of missing persons projection of stature from bones plays an important role. Fragments of long bones are usually the only medicolegal evidence available after post-mortem gnawing by wild animals, mutilation and injuries. The femoral length and stature of individuals are determined from fragments of the upper end of femur, shaft and distal end of the femur.

Introduction: The stature of an individual, one of the key elements of identification, can be calculated from the length of long bones in the body, of which the femur has the highest correlation with stature. Many a times, forensic anthropologists have to identify unknown dead bodies from fragments of bones that are available. Studies have proven that the total length of a bone can be estimated from fragments using population-specific regression equations. In the present study, the objective was to estimate the total length of the femur (TFL), in an Indian population, from measurements of its distal segment, using regression equations. Material and Methods: One hundred and twenty-one intact adult femurs were studied. The TFL and four variables from its distal segment were measured. Linear regression analysis was performed, and regression equations were derived to calculate the TFL from each of the variables. Results: The mean TFL was 41.9 ± 3.4 cm. All the four parameters of the distal segment showed a significant positive correlation with the total femoral length (P < 0.001), and of these, the width measured between the two epicondyles showed the maximum correlation. Multivariate and univariate regression equations were derived to estimate the TFL from these variables. Discussion and Conclusion: The TFL can be reliably calculated from the measurements of the distal fragments. These measurements can be used by forensic anthropologists for the estimation of the stature of an unknown individual.
