Summary
Forensic anthropology can estimate stature using the second cervical vertebra. Measurements like the maximum height of the axis (AMA) strongly correlate with height in the Iranian adult population.
Area of Science:
- Forensic anthropology
- Osteology
- Medical imaging
Background:
- Cervical vertebrae are durable skeletal remains, often crucial in identifying individuals.
- Accurate stature estimation is vital in forensic investigations.
Purpose of the Study:
- To evaluate the utility of linear dimensions of the second cervical vertebra (axis) for estimating stature.
- To establish correlations between specific axis measurements and stature in an Iranian adult population.
Main Methods:
- A cross-sectional study involving 66 adult Iranian participants (33 males, 33 females).
- Three-Dimensional Computed Tomographic Scanning (3D CT Scan) was used to measure 15 linear indexes of the second cervical vertebra.
- Statistical analyses included Chi-square, T-student, and logistic regression tests.
Main Results:
- The maximum height of the axis (AMA), maximum length of the axis (CMA), and sagittal maximum body diameter (DSMC) showed a significant positive correlation with stature.
- AMA (r=0.470, P=0.0001), CMA (r=0.320, P=0.007), and DSMC (r=0.281, P=0.019) were identified as reliable indicators.
Conclusions:
- Linear dimensions of the second cervical vertebra, particularly AMA, CMA, and DSMC, are valuable for estimating stature in the Iranian adult population.
- 3D CT scanning provides accurate measurements for forensic anthropological applications.
