Summary
This study reconstructs 3D osteon morphology in human trabecular bone. Osteons are broad, thin plates, necessitating surface-proportional sampling for accurate morphometric analysis.
Area of Science:
- Bone biology
- Histology
- Stereology
Background:
- Random histologic sections incompletely represent bone remodeling sites.
- Understanding osteon 3D morphology is crucial for accurate bone analysis.
Purpose of the Study:
- To reconstruct the three-dimensional (3D) morphology of osteons in human trabecular bone.
- To evaluate the suitability of 2D profiles for morphometric studies.
Main Methods:
- Reconstruction of osteons from serial sections of decalcified human trabecular bone.
- Analysis of osteon shape, dimensions, and bounding surfaces.
Main Results:
- Osteons were reconstructed as broad, thin plates with parallel lamellae.
- Plates were bounded by the marrow surface and an irregular cement plane.
- Osteon thickness was significantly less than other dimensions, suggesting a plate-like model.
Conclusions:
- The plate-like morphology of osteons is suitable for stereologic studies.
- 2D profiles are not appropriate sampling units for morphometric studies due to unequal surface extent.
- Sampling for thickness estimation must be proportional to profile surface area.
