“…However, there was no statistically significant difference between the mean femoral length of Ghanaian males and the mean reported for Indians [9]. Unlike males, there was a statistically significant lower difference between the mean femoral length of Ghanaian females and means reported for South African Whites and Indians [8,9]. Again, these differences could result from the differences in ethnicity and race which have been shown to contribute immensely to interpopulation variation.…”

“…The mean femoral length of Ghanaian males differed significantly (p < 0.05) from that reported for South African Whites [8] and the mean femoral length of Ghanaian females also differed significantly from the means reported for South African Whites and Indians [8,9]. These differences could result from the differences in race, nutritional status and occupation which all have been shown to contribute significantly to inter-population variation [10].…”

Osteometric indices have a direct relationship with sex, height, age and race of an individual. These factors play a pivotal role in the identification of an individual. There are very few reports in Ghana on the use of bones for personal identification as compared to the developed world. Therefore the present study sought to use the ulna and femur as models for height and sex determination. One hundred undergraduate students of the Kwame Nkrumah University of Science and Technology, Kumasi made up of 55% males and 45% females between the ages of 18 -45 years were recruited for the study. The total standing height, ulnar and femoral lengths were measured. The data was analysed using excel and SPSS version 20.0. In the present study, males were taller than females (p < 0.05). Ulnar and femoral lengths were significantly higher in the male participants than in the females. Ulnar length was the better index for estimating height and the right femoral length was the better model for sex determination in the participants. Therefore the ulnar and right femoral lengths can serve as preliminary useful tools for height and sex determination. The results of this study serve as baseline data for future studies.

“…The most valuable variable was EB, but it was not determined that breadth-related variables were better discriminators than length-related variables. However, in studies of South African [3], German [13], and Indian [18] populations, breadth-related variables were better discriminators than length-related variables. Iscan and Shihai [7] supported the findings of earlier studies indicating that breadth and circumference measurements of long bones are often more sexually dimorphic than linear dimensions such as length.…”

“…However, many authors [2,4,6,7,12,13,[18][19][20][21] did not report uniform values for all races studied in different populations. Anthropometric dimensions vary among populations, even in subjects on the same continent, and these variations are attributed to genetic and environmental factors.…”

Objectives: Estimating the sex of decomposed corpses and skeletal remains of unknown individuals is one of the first steps in the identification process in forensic contexts.Although various studies have considered the femur for sex estimation, the focus has primarily been on a specific single or a handful of measurements rather than the entire shape of the bone. In this article, we use statistical shape modeling (SSM) for sex estimation. We hypothesize that the accuracy of sex estimation will be improved by using the entire shape. Materials and Methods:For this study, we acquired a total of 61 femora from routine postmortem CT scans at the Institute for Forensic Medicine of the University of Zurich. The femora were extracted using segmentation technique. After building a SSM, we used the linear regression and nonlinear support vector machine technique for classification.Results: Using linear logistic regression and only the first principal component of the SSM, 76% of the femora were correctly classified by sex. Using the first five principal components, this value could be increased to 80%. Using nonlinear support vector machines and the first 20 principal components increased the rate of correctly classified femora to 87%.Discussion: Despite some limitations, the results obtained by using SSM for sex estimation in femur were promising and confirm the findings of other studies. Sex estimation accuracy, however, is not significantly improved over single or multiple linear measurements. Further research might improve the sex determination process in forensic anthropology by using SSM.
