It presents a standardized technique for establishing anatomically meaningful landmarks for measuring vertical and horizontal diameters of the femoral head, based on weight transmission. The study was conducted at the Medicolegal Institute of Bhopal, India, on a sample comprising of 124 individuals (80 males and 44 females), the majority of them being medicolegal specimens. The mean age was 58.3 years for males and 52.4 years for females. To check the efficacy of the newly suggested method, the bones were also measured for maximum vertical and horizontal diameters following traditional anthropometric techniques. The method based on “non-conventional” measures was found to be more accurate (94.7% for vertical and 95.2% for horizontal diameter) as compared to the traditional techniques. Intra- and inter-observer statistics are also presented.

The present study investigates the potential candidature of external ear as a tool for identification even among genetically related persons. The study investigates its uniqueness, the degree of morphological similarity/dissimilarity of its features and identifies the most variant features of them. The knowledge of the ear features whose expressions are variable even in genetically related persons could be useful in establishing personal identity. The study sample included members of 90 general and 30 tribal families of Central India. A validation study was performed on members of 54 North Indian families. Adopting Somatoscopic method ten characters of the external ear were analyzed. To investigate the variability in ear features of the closest genetic relation 90 monozygotic twin pairs were also included in the study. Analysis of the data found that none of genetic relations except on...

The cause of its formation is a long debated issue. The present study is an attempt to identify by anthropometric means the sexually dimorphic features in the bones of the elbow joint which makes the ‘Carrying angle’ a sex indicator. The distal end of the humerus and the proximal end of ulna playing major role in the formation of ‘Carrying angle’ have been examined for sex difference. The two measurements of the humerus (Trochlear angle and Inclination angle of Olecranon fossa) and three measurements of the ulna (Olecranon - coronoid angle, length and width of inferior medial trochlear notch) were devised for the study. Though the humeral angles failed to show any sex difference, the angle and dimensions of ulna exhibited statistically significant result. Could these parameters be the cause of sex differences the ‘Carrying angle’ exhibits at the elbow joint?

The advent of sophisticated electronic gadgets though on one hand has multiplied the problem manifold, on the other, has introduced new techniques for surveillance and monitoring crime. Biometric is one such tool which uses human characteristics for personal identification. Ear biometrics, a relatively new class of biometric trait for personal identification has been discussed in this paper. A brief introduction to the field and review of leading works including those appearing in the research world lately are discussed. © Kamla-Raj Enterprises 2007 Anthropology Today: Trends, Scope and Applications Anthropologist Special Volume No. 3: 215-218 (2007) Veena Bhasin & M.K.

This paper attempts to study facial bilateral asymmetry and its changing pattern with age and sex among 200 Dangis and 177 Ahirwars of Khurai block in Madhya Pradesh. Seven facial measurements (five horizontal, two vertical) were taken on subjects categorized into three age groups (3–11 years, 12–20 years and above 20 years). The mean and absolute bilateral differences when compared between different age groups and sexes failed to show significant results for most of the measurements. Bilateral facial asymmetry assists in evaluating patients before cranio– facial surgery. Asymmetric measurements are also useful for orthodontics. It is also an important parameter in skull super imposition and photographic comparison.

There is no detailed somatoscopic study of the ear morphology concerning the entire Indian subcontinent. Hence, in the present study an attempt has been made to report the frequency of various somatoscopic features of various parts of the auricle of adult males and females who live in the central region of India. In both sexes oval-shaped ears and normally rolled helix were most common. The preauricular region was found to be clear with very few cases of the occurrence of pits and sinuses. Free lobules were more frequent among females than males but it was vice versa for Darwin's tubercle. The position of the ear's upper edge was most commonly located at the eyebrow tail while its lower edge was located at an upper lip level in both sexes. Hypoplastic lobules were noted in one-fifth of males but were very rare among females. Very few cases of lop ear, preauricular appendage and preauricular pit were observed. Some of these somatoscopic features act as soft biometric traits that improve the performance of the primary biometric system of personal identification. Somatoscopy of external ear acts as an aid to surgeons while reconstructing deformed ears and also helps physicians in detecting anomalies, for example, Edward's, cleft lip/cleft palate syndromes.

Anthropometric measurements on 12 inter-landmark linear distances have been carried out for both left and right ears of 700 male and female individuals. A 12-dimensional feature space has been framed to represent each ear pattern as a feature vector with the measured inter-landmark distances as its components. The Euclidean distances in such a feature space amongst all possible pairs of ear patterns of both male and female individuals have been computed. Very few pairs have distances which fell below the safe distinction limit. The undistinguished pairs were further examined by direct superimposition of their images. None of the ear patterns is found to be exactly the same in morphology to the other. Even the left and right ears of the same individual are not identical. Thus, the present study reconfirms the individuality of ear patterns. For establishment of identity, a questioned profile view facial image can be compared with a control one on the basis of the ear pattern visible in it.
