Summary
This study tested the Thompson technique for estimating age from adult bone histology. While generally accurate, some discrepancies and overestimations occurred, suggesting a need for further refinement.
Area of Science:
- Forensic Anthropology
- Paleopathology
- Bioarchaeology
Background:
- Assessing biological age from skeletal remains is crucial in forensic and archaeological contexts.
- Histological analysis of cortical bone offers a method for age estimation.
- The Thompson technique is a specific histological method for age determination.
Observation:
- Adult skeletal remains from 19th-century cemeteries were analyzed using the Thompson technique.
- Age estimates from anterior and peripheral microscopic fields showed general agreement, but 6/29 femora had marked differences.
- Unilateral trauma did not consistently affect age estimates.
- Among 16 individuals of known age, 8 were accurately estimated, 5 overestimated, and 3 underestimated.
Findings:
- The Thompson technique demonstrated relative robustness in age estimation from cortical bone.
- Discrepancies between sampling locations and overestimations suggest potential issues.
- Cortical erosion or diagenetic destruction may lead to overestimation by obscuring key bone regions.
Implications:
- The Thompson technique, despite limitations, shows promise for skeletal age assessment.
- Further development is warranted to improve accuracy and address sources of error.
- This histological method can contribute to more precise age profiles in historical populations.
