“…In this range the measurement accuracy which is + 2 mm due to the resolution of the sonographic apparatus becomes noticeable as a larger coefficient of variation. This phenomenon has also been noted by other [5,6,7]. Thus the coefficient of variation for the femur at 28 weeks is 4% and at 12 weeks it is 15%.…”

“…The difference of his values with our P 50 is generally ± 1 mm. The values published by QUEENAN et al [5], HOHLER and QUETAL [3], HOBBINS [2], and TBRINDE et al [7] are generally 1 to 3 mm above those obtained by us. The data by JEANTY et al [4] at 18 weeks are 2-3 mm above our values but by the 34th week 2 mm below them.…”

“…The values for two standard deviations frequently found in the literature [5,6,7] are generally between 2 and 8 mm and increase with duration of pregnancy. We suggest that data with the following characteristics should be critically reviewed, namely, those where (1) the standard deviations fluctuate markedly from week to week; (2) the standard deviations are larger in earlier pregnancy than in later pregnancy and (3) radius and ulna are indicated as being equally long [6,7].…”

“…SCHLENSKER [6] proceeded as we did and obtained direct measurements on bone preparations from stillbirths. QUEENAN et al [5] validated their sonographic data by comparing them with radiographs on stillborn fetuses. These authors concur that the accuracy of sonographic measurements is ± 2 mm.…”

Technical note: Error in Olivier and Pineau's regression formulae for calculation of stature and lunar age from radial diaphyseal length in forensic fetal remains

Stewart ([1979] Essentials of Forensic Anthropology, pp. 128-131) cites five regression formulae presented by Olivier and Pineau ([1960] Ann. Méd. Lég. 40:141-144) for estimation of fetal stature from diaphyseal length. Of these formulae, one appears problematic: the formula for calculation of stature from the radius yields values which suggest the fetus has a much greater crown-heel (CH) length than do the remaining formulae for the diaphyses of other long bones. Moreover, when this stature estimate, so derived, is then inserted into these authors' earlier general formula for estimation of lunar age (Olivier and Pineau [1958] Arch. Anat. 6:21-28) the error is compounded. A fetus is now indicated to be nearly a trimester older than when the CH lengths obtained by the other long bone formulae are used. Accordingly, we believe this particular formula, unlike the others, is incorrect and should not be used to estimate lunar age from fetal remains.

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.
