This study examined indicators of male-female differences in the os Coxa, specifically in
the shape of the ilium and iliac crest for the purpose of skeletal sex estimation. The iliac crest is a
curved, or “S” shaped, epiphysis which extends along the cranial margin of the ilium, posteriorly
from the anterior superior iliac spine to the posterior superior iliac spine of the os Coxae. Forty
two metric variables characterizing the shape of the os Coxa and iliac crest were derived from a
digital database of 150 adult White human os Coxae, including 75 males and 75 females, from
the Hamann-Todd osteological collection at the Cleveland Museum of Natural History. The os
Coxae were all digitized using a MicroScribe-3DX digitizer, and the data was stored in an excel
spreadsheet, which facilitated further mathematical analysis to define and calculate all variables.
A single point of origin defined as the most superior point in the midline of the pubic symphysis,
was common to each variable. This study hypothesized that these variables will better define
variation in form, and that they will better characterize sexual dimorphism in the iliac crest. Thus
serve as an aid in sex estimation. Additionally, the qualitative observation of the sciatic notch
was compared to the quantitative observations. Statistical analyses, including descriptive
statistics, univariate sectioning points, independent t-tests, and proportional analyses, were used
to test the potential application of the findings of this study to sex identification in osteological
investigation. The results of this research suggested that there were slight indications of sexual
dimorphism in several of the iliac blade dimensions along with the central chords of the iliac
crest and their associated angles. Despite indications of differences in the female and male form,
the measurements proved to be too variable, thus making accuracy and reliability unattainable.
Further investigations are required to better understand the presented findings. |
