“…A study using a geometric-morphometric approach demonstrated that size differences did not have a significant effect on craniofacial shape, although sex differences did [47]. Size differences between males and females have been reported on the Spanish population for cranial, dental and postcranial elements [48][49][50]. Our results using the two online methods demonstrated an overall higher accuracy rate for males than for females, perhaps accounting for the sexual dimorphic differences.…”

“…The first step in identifying individuals from bone remains is to estimate the sex, given the difference between sexes in the formulas employed to estimate age and stature. Various anthropological studies have been published on sex estimation in Spanish populations [ 9 , 26 , 27 ], and research has been conducted on the sexual dimorphism of the scapula in other populations ( Table 5 ) as Hamann-Todd collection, in a sample of american individuals of late 19th–early 20th century [ 4 ] or Italian population of 21 st Century [ 7 ]. Bone remains from a contemporary Granada population were investigated in 1998 by Alemán et al to explore the usefulness of different bones for sex estimation, including the scapula [ 22 ].…”

Anthropometric studies of the scapula have been rare in Spanish populations, nevertheless they are of current interest in forensic anthropology for estimation of sex. Although the estimation of sex is usually carried out on the pelvis and skull, other measurements related to the scapula can be helpful when the skeletal remains are incomplete. Glenohumeral osteoarthritis development is influenced, among others, by the morphology of the scapula, which is one of the less studied aspects. We carried out a descriptive study of anthropometric parameters in a series of 157 scapulae (82 individuals) on bone remains dated to the 20th century from a population of Granada (Southern Spain). Seventy seven (49%) were right-side and 80 (51%) left-side; 72 (45.9%) were from males and 85 (54.1%) from females, and the mean age at death was 70.76±11.7 years. The objective was to develop a discrimination function for sex estimation based on anthropometric parameters of the scapula other than those considered to date, and to analyze the prevalence of glenohumeral osteoarthritis in relation to selected anthropometric parameters. A logistic regression model based on parameters of the upper-external segment of the scapula was done. The obtained formula: 1/1+e^ (- (-57.911 + 0.350*B + 0283*C + 0.249*b + 0.166*a +-0.100*β) classifies male sex with 98.3% accuracy and female sex with 92.1%. Glenohumeral osteoarthritis was detected in 16.6% of individuals and was related to age (p<0.05), scapular length (p<0.05), glenoid width (p<0.05), glenopolar angle (p<0.05), and α angle (p<0.05) in bivariate analyses but showed no significant associations in multivariate analyses. This approach can be useful for anthropological-forensic identification when scapula remains are incomplete. Glenohumeral osteoarthritis is significantly associated with a smaller α angle.

“…The more bones available and in a better state of preservation, the greater probability to obtain reliable sexual evaluation results [6]. For these reasons is important to establish reliable methodologies and techniques that enable sex estimation using other skeletal structures when pelvis and skull are not available or damaged [1,[9][10][11]; in these cases, long bones have provided high allocation accuracies for sex diagnosis [12,13], followed by ribs [14,15], vertebrae [16,17], sternum [14,18], patella [19,20] and the bones of hands and feet [21,22].…”

In archaeological and medicolegal contexts, sex estimation is a crucial parameter to personal identification. However, it can be a complex task if the skeletal remains are damaged or fragmented. For this reason, is important to establish new reliable methodologies and techniques using alternative sexually dimorphic anatomical regions than pelvic and skull such as vertebrae. The purpose of the current study was to evaluate the level of sexual dimorphism of first, second and seventh cervical and twelfth thoracic vertebrae from the Coimbra Identified Skeletal Collection of the University of Coimbra (Portugal) and to develop logistic regression equations for sex estimation based on metric data from these vertebrae. The sample comprised 73 individuals (38 males and 35 females) with a mean age of 50.10±18.34 years. Eleven multivariate logistic regression equations were developed with accuracy rates between 80.0% and 92.5%. The first cervical vertebra demonstrated to be useful for sex diagnosis when more sexually dimorphic anatomical regions (i.e., pelvis and skull) are not available or suitable for analysis.
