“…Several visual scoring methods have been proposed (Meindl et al, 1985;Bruzek, Walker, 2005). These methods are less influenced by the landmarks of the notch at both ends; however, they tend to be more subjective and may require special osteological training.…”

Curvature of the greater sciatic notch in sexing the human pelvis

The maximum curvature of the greater sciatic notch and two standardized indices were calculated for use in the sexing of human hip bones. This was done by means of quadratic regression of the contour points of the greater sciatic notch. The new variables are not directly affected by the osteometric landmarks (e.g. ischial spine, tubercle of the piriformis, and posterior inferior iliac spine) which determine the greatest width of the notch. These landmarks are, however, known to be ill-defined on occasion, but nevertheless have been used to derive the conventional depth-to-width index and angles of the sciatic notch. The curvature parameter and its new indices were applied to the sciatic notch of 164 Japanese hip bones of known sex (104 males and 61 females). The accuracy of the new variables in the determination of sex was assessed and compared with that of the conventional indices and angles of the sciatic notch. The best discriminating variable was found to be the posterior angle with an accuracy of 91%. The new parameters of the present study that represent localized shape of the sharply curved edge of the notch diagnosed sex with an accuracy of 88%. In paleoanthropological or forensic cases, using the maximum curvature of the sciatic notch and its indices may be applicable to sexing the hip bones of specimens with postmortem damage.

“…La estimación sexual de los restos óseos humanos constituye uno de los primeros pasos necesarios para abordar problemas paleodemográficos, patológicos, de biodistancia, entre otros (Meindl et al 1985). El dimorfismo sexual es el resultado fundamentalmente de la acción conjunta de factores genéticos y fisiológicos, aunque también pueden intervenir factores ambientales ligados al crecimiento y desarrollo (Loth y Henneberg 2001;Oyhenart et al 1999;Pucciarelli et al 1993).…”

“…En los 9 individuos restantes no se pudo determinar el sexo debido a que no tienen dichas estructuras diagnósticas por encontrarse en mal estado de conservación o por estar ausentes por procesos de remoción antrópicos postdepositacionales (Chiavazza 2005). La edad al momento de la muerte se estimó de acuerdo con los cambios morfológicos de la sínfisis púbica (Brooks y Suchey 1990; Todd 1921) y de la superficie auricular (Lovejoy et al 1985).…”

Páginas 00-00 Chungara, Revista de Antropología Chilena Los esqueletos incompletos y huesos humanos aislados constituyen un volumen importante del material recuperado en templos coloniales americanos. Esta situación lleva a la necesidad de realizar procedimientos que permitan la asignación sexual de cada elemento con el fin de profundizar diversos tipos de estudios bioantropológicos. El objetivo de este trabajo es desarrollar funciones discriminantes para estimar el sexo a partir de huesos largos en una muestra recuperada en tres templos coloniales de Mendoza (Argentina) correspondiente al período entre los siglos XVII y XIX. La muestra comprende 61 individuos adultos (entierros primarios completos), con sexo determinado a partir de indicadores pélvicos y craneanos. En cada caso, se tomaron un conjunto de medidas del húmero, radio, ulna, clavícula, tibia y fémur que fueron empleadas para generar funciones discriminantes. Las funciones desarrolladas permitieron estimar el sexo con un elevado porcentaje de asignaciones correctas, siendo el fémur (92,1%) y el húmero (90%) los elementos con porcentajes promedio de estimaciones correctas más altos y con porcentajes más elevados en el sexo masculino que en el femenino. La ulna (79,3%), la clavícula (79,2%), la tibia (75,9%) y el radio (73,3%) obtuvieron un poder de clasificación más bajo. Los resultados son discutidos considerando factores genéticos, ambientales y tafonómicos de la muestra estudiada.Palabras claves: estimación sexual, esqueleto postcraneal, poblaciones históricas, norte de Mendoza. Incomplete skeletons and commingled human bones constitute a significant volume of recovered material in American colonial temples. This poses the need to perform procedures that allow the sexual assignment of each element in order to deepen various types of bioanthropological studies. The objective of this work is to develop discriminant functions to estimate sex from long bones in a sample

“…3,4 An example of such a method is that developed by Phenice,5 which is widely used and has been tested on various populations. The skull, after the pelvis, is the skeletal region most frequently used for sex determination.…”

“…One of the disadvantages however, is that discriminant function analysis is highly population-specific and can cause high error rates when used for cross-population observations. 3,8 Another limitation with using the cranium for sexing is that it is often fragmented, both in archaeological and modern contexts. In contrast, the mandible is generally more durable and thus N o n -c o m m e r c i a l u s e o n l y is usually better preserved.…”

An anthropometric method for sex determination from the mandible: test on British Medieval skeletal collections

et al. 2017

Sex determination is a vital part of the analysis of skeletal remains and the creation of biological profiles that aid in identification. The pelvis and skull are the regions usually employed by anthropologists and produce very good results. However, the mandible, being a very durable bone and frequently preserved has not received the attention that other skeletal elements have. There are some morphological methods for sexing the mandible, however metrics are considered to be more objective and easier to replicate. This study uses the measurements of the bimental breadth and the corpus thickness of the mandible. Univariate and multivariate analysis was carried out to create discriminant function equations. These equations can be used to sex a mandible with overall accuracy rates as high as 77.3%. The results of the present research are similar to those of other studies and indicate that mandibular metrics can be relied upon for sex determination, especially in cases where other elements are not preserved.
