Hypothesis
The study investigates the effect of age on bone mineral density and microarchitecture in the radius and tibia of horses.
Conclusion
Age-related changes in the bones were observed, which may explain the higher incidence of fractures in older horses.
Supporting Evidence
- The number of trabeculae decreased significantly with increasing age.
- The distance between trabeculae increased significantly with age.
- Bone density and microarchitecture were not affected by breed or gender.
Takeaway
As horses get older, their bones change in structure, which might make them more likely to break.
Methodology
Xtreme computed tomography was used to evaluate the bone structure of 56 bones from 15 horses aged four to 21 years.
Potential Biases
Potential bias due to the limited number of horses and the specific conditions under which they were euthanized.
Limitations
The study was limited to a small sample size and specific breeds of horses.
Participant Demographics
15 horses (9 geldings and 6 mares) aged 4 to 21 years.
