Hypothesis
The study aims to investigate the morphological factors that could have affected the prevalence of trauma-related vertebral fractures from medieval times to the present day.
Conclusion
The shape and size of the 4th lumbar vertebra have changed significantly from medieval times, affecting the biomechanical characteristics of the lumbar vertebral column.
Supporting Evidence
- The vertebral height has increased significantly from medieval to modern times.
- Vertebral width has decreased significantly in both male and female samples.
- Changes in vertebral dimensions are correlated with changes in stature over time.
Takeaway
This study found that the bones in our backs have changed over time, which might make them more likely to break today than in the past.
Methodology
The study measured the size and shape of the 4th lumbar vertebra using MRI and calipers from modern Finns and medieval archaeological samples.
Potential Biases
Potential bias may arise from the selection of samples and the methods used for measuring vertebral dimensions.
Limitations
The study is limited by the geographical variation in the samples and the historical context of the medieval populations.
Participant Demographics
The modern sample consisted of Caucasian males and females, while the medieval samples included individuals from Sweden and Britain.
