Bioarchaeology
Skeletal Biology

Background:

Accurate age estimation from adult skeletal remains is vital for biological profiling.
Current histological methods for aging exhibit limitations in accuracy, precision, and replicability.

Purpose of the Study:

To develop and validate a novel 3D volumetric method for quantifying histological remodeling events.
To enhance existing histological techniques for adult age-at-death estimation.

Main Methods:

A 3D volumetric approach using serial sections of human femur, circular polarizing microscopy, and geographic information systems (GIS).
Interpolation of osteon volume using ArcGIS and geometric functions.
Statistical comparison of osteon volume across different femoral octants using ANOVA.

Main Results:

Osteon volume exhibited uniformity on the medial femur but high variability on the lateral aspect.
Specific octants showed significant differences in mean osteon volume.
A minimum sample of 100 osteons was found to be statistically robust for analysis, while 30 was insufficient.

Conclusions:

Osteon volume can be reliably interpolated using spatial geometry and GIS applications.
This volumetric method shows potential as a tool to improve adult age-at-death estimation techniques.
The study highlights the importance of sample size and spatial distribution in histological aging analyses.
