“…Regarding the two parameters mentioned above and also concerning the current study namely FHD and FND, prolific related literature alleged that the measurements of the proximal epiphysis performed greater accuracy over other features of the femur in a variety of populations studied worldwide: Central Indian [2], Egyptian [4], South African Whites [5], Greek [10], Croatian [11], Thai [12], Bosnian [13], German [14], North-eastern Chinese [15], Spanish [16][17][18], Northwest Indian ethnicities [19], as well as American Blacks and Whites [22]. On the contrary, Steyn et al considered the distal end of the femur to have better predictive ability compared to the proximal epiphysis among South African Whites [5].…”

The current study was undertaken to test the validity and reproducibility of the Purkait triangle method and some alternative proposals for sex prediction from the proximal femur in the adult population of Spain. To that end, sexual dimorphism of the maximum femoral head diameter and the minimum femoral neck diameter were also evaluated. The study was conducted on 186 femora (109 males and 77 females) taken from the San José collection of identified individuals (Southern Spain). Discriminant function analyses (DFA) employing the jackknife procedure for cross-validations were considered. Overall, more than 94% of individuals of both sexes were correctly classified. The most dimorphic single variable from the triangle method was the intertrochanteric apex distance (BC) that reached 85.5% accuracy, falling below those obtained for the femoral head and femoral neck diameter, respectively, (89.8 and 91.9%). Combining BC with the neck diameter, the predictive ability increased to 92.5%; when femoral head diameter was added to the latter two, the classification success rate improved further up to 94.6% (94.1% after cross-validation). We conclude that the classification success rates of the Purkait's method remained considerably below any of those obtained with the models proposed in the present study which proved to be a much better and more reliable choice both as single predictors and in combination with other variables.

“…The findings of the present study is consistent with the findings of a study by Soniet al who used discriminant function analysis to determine sex from femur. Seven parameters of the femur were measured and it was noted that maximum length of the femur was sexually dimorphic with an accuracy of 85% in males and 72.5% in females [24]. Steyn and Yasar used the femur and tibia to determine sex in South African whites and reported that, the maximum lengths of both femur and tibia were sexually dimorphic [8].…”

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.

“…There have been few studies on Indian samples in which sex is determined from femur. [24][25][26] The sexing potential of the epicondylar breadth is well known. The present study has confirmed that for sex determination, the measurements of the Epicondylar Breadth of femur display higher classification accuracy.…”

“…[8] Nakahashi and Nagai, [17] Tagaya, [18] Yoshino and Kato et al [19] and Sakaue, [20] studied sex determination from various bones in both recent and prehistoric Japanese populations. Little work on the subject has been reported from India except for the study by Singh (1972A and1972B), [21,22] on the head of femur, the study by Ruma Purkait on proximal femur, [23] the study by Rashmi Shrivastava(2012), [25] and Gargi Soni (2010), [26] on various ISSN (0): 2455-5274; ISSN (P): Vora & Patel; Determination of Sex from Epicondylar Breadth of Femur measurements of femur.

Introduction: Sex determination from skeletal remains allows one to narrow the search in individual identification. As the femur shows 75% Variation between individuals, it has been useful for sex determination. There are many possible femoral measurements, but the Epicondylar breadth is routinely considered to be useful for sexing individuals. To date, nothing has been published on other measurements of distal femur, which may be useful if the bone is fragmented, and only lower part of bone is available. This study is an attempt to evaluate sex determination from distal femora of Indian origin. Subjects and Methods: For this study total 208 normal dry human femur bones of known sex were studied, which were collected from various medical colleges of Gujarat. For measurement of Epicondylar breadth of femur, Digital sliding vernier caliper was used. Results: The discriminant function equation for sex determination from Epicondylar Breadth (EB) of femur is:-Y = 0.143 * EB + (-8.334) If Y is < 0 then the sex of the bone is Female and if Y is > 0 then the sex of the bone is Male. Conclusion: With the use of discriminant function score, 87% of femur samples are correctly predicted about sex. The results of this study is particularly useful in a case for sex determination in which the skeletal remains of an individual are incomplete or damaged and thus more accurate bones such as the pelvis or cranium are absent.
