“…This result is in accordance with earlier observations among different populations in which males have consistently larger dimensions when compared to females [24–26]. Earlier studies among Sudanese showed that among lower limb dimensions, breadth dimensions are more sexually dimorphic than length dimensions [11].…”

The presence of an isolated limb or limb parts from different individuals presents a major challenge for medicolegal investigators in establishing identification in cases of wars, mass disasters, and criminal assaults because different populations have different sizes and proportions. The measurement of lower limb dimensions showed a high success rate in establishing individual identity in terms of sex and stature in various populations. However, there is a paucity of data concerning the correlation within the lower limb parts. This study aims to assess the existence of relationships within lower limb parts and to develop regression formulae to reconstruct limb parts from one another. The tibial length, bimalleolar breadth, foot length, and foot breadth of 376 right-handed Sudanese adults were measured. The results showed that all variables were significantly larger in males than in females. A significant positive correlation (P < 0.001) was found within the lower limb parts. Sex-specific linear equations and multiple regression equations were developed to reconstruct the lower limb parts in the presence of single dimension or multiple dimensions from the same limb. The use of multiple regression equations provided a better reconstruction than simple regression equations. These results are significant in forensics and orthopedic reconstructive surgery.

“…The percentages of classification accuracy obtained in our study are comparable with other studies using metric analysis on the tibia for other populations [34,35]. An anthropometric investigation comparing cranial and postcranial elements for sex estimation revealed that postcranial skeleton performs better than cranial when using multivariate analysis [36].…”

Sexual dimorphic variation between populations must be taken into consideration when applying existing methods on unrelated samples. Validation studies are extremely important to avoid misclassification and ensure high quality standards.This paper presents a test of a Southern European metric method on Greek-Cypriots (N=132) and Turkish (N=203). Three tibia measurements were taken, sex differences were explored using a Wilcoxon test and the parameters were applied to the original discriminant functions.The results showed accuracy rates ranging from 79 to 86% for Greek-Cypriots and from 80 to 88% for Turkish. Differences in the performance of the formulae applied were observed between the samples. Correct classification rates are very similar to the ones reported by the original method.This study demonstrates that the application of the Southern European method to estimate sex on these two Mediterranean populations is reliable. A larger and more diverse sample is required to verify our results.

“…Because of its robustness and post-depositional resistance, the human tibia is an important skeletal element for identifying sex in both archaeological and forensic contexts [26–29]. Sex-related differences in the proximal tibia have also been studied extensively by orthopaedic surgeons.…”

Sexual Dimorphism of the Human Tibia through Time: Insights into Shape Variation Using a Surface-Based Approach

et al. 2016

In this paper we present a three-dimensional (3D) morphometrical assessment of human tibia sexual dimorphism based on whole bone digital representation. To detect shape–size and shape differences between sexes, we used geometric morphometric tools and colour-coded surface deviation maps. The surface-based methodology enabled analysis of sexually dimorphic features throughout the shaft and articular ends of the tibia. The overall study dataset consisted of 183 3D models of adult tibiae from three Czech population subsets, dating to the early medieval (9–10th century) (N = 65), early 20th century (N = 61) and 21st-century (N = 57). The time gap between the chronologically most distant and contemporary datasets was more than 1200 years. The results showed that, in all three datasets, sexual dimorphism was pronounced. There were some sex-dimorphic characteristics common to all three samples, such as tuberosity protrusion, anteriorly bowed shaft and relatively larger articular ends in males. Diachronic comparisons also revealed substantial shape variation related to the most dimorphic area. Male/female distinctions showed a consistent temporal trend regarding the location of dimorphic areas (shifting distally with time), while the maximal deviation between male and female digitized surfaces fluctuated and reached the lowest level in the 21st-century sample. Sex determination on a whole-surface basis yielded the lowest return of correct sex assignment in the 20th-century group, which represented the lowest socioeconomic status. The temporal variation could be attributed to changes in living conditions, the decreasing lower limb loading/labour division in the last 12 centuries having the greatest effect. Overall, the results showed that a surface-based approach is successful for analysing complex long bone geometry.
