“…Accurate identification of fetal age is important in clinical, forensic, and archaeologic contexts. Although age estimates of living fetuses are commonly made in utero through ultrasound measurements (1–7), many forensic and archaeologic situations present only limited material for examination (8). Clearly there is a need to maximize the number of potential gestational age estimators.…”

This study evaluates a new method of fetal age estimation based on orbital measurement and including the potential trisomy 21 of the fetus. Six orbital and one facial CT-scan measurements were taken on 71 fetuses ranging from 14 to 41 weeks of gestational age. Forty-eight fetuses were "normal" and 23 fetuses presented the Down syndrome (trisomy 21). The anatomy/imagery correspondence was evaluated comparing our results to those obtained by direct bone measurements on the same fetuses and revealed no significant differences between the two kinds of measurements. Moreover, a multiple linear stepwise regression was realized to estimate fetal age and showed that the "trisomy 21 parameter" is not conserved in the final determination model. Therefore, we conclude that the good radio-anatomical correspondence offers an interesting alternative to direct bone measurement (necessitating dissections) and allows a reliable fetal age determination, whatever is the trisomy 21 condition of the fetus.

Accurate identification of fetal age is important in a wide variety of circumstances. Seventeen anthropometric and radiographic measurements were taken on fetuses between 15 and 42 weeks of gestational age, both with and without pathologic conditions. A full evaluation including radiographic, karyotypic, gross anatomic, and histologic examination of the fetus and placenta identified 72 individuals as nondysmorphic with no signs of chronic uterovascular insufficiency. These specimens served as the control group. Based on least-squares regressions of this group, age-estimation equations were calculated for all variables. Six models were adequately described by linear equations; the remaining 11 required a quadratic term. Based on standard error of the estimate (S(y:x)), skeletal measures proved the most accurate age estimators. Pathologic conditions were shown to have an influence on age estimation indicated by high levels of inaccuracy and, in some instances, significant bias.

Forensic anthropology can be described as the analysis of human remains for the medicolegal purpose of establishing identity. It is a multidisciplinary endeavor that applies the knowledge of biological anthropology and human osteology to cases where human remains are skeletonized, or where a detailed understanding of the growth and development, morphology, or norms of the human body can assist other disciplines in positive identification. This is achieved through the use of osteobiographical markers, which aid in the determination of four primary characteristics: skeletal age, sex, ancestry, and living stature. These are supplemented by markers of personal identity, which are likely to be specific to an individual, or that may be determined so with varying degrees of statistical certainty. Such markers include both soft and hard tissue traits, some of which are biologically normal but specific to an individual, whereas others are pathological or abnormal, arising as the result of disease, trauma, surgical intervention, or cosmetic/aesthetic alteration.
