Yield behavior of bovine cancellous bone.

Summary

Compressive yield strain in bovine cancellous bone is primarily influenced by bone density, not trabecular orientation. Bone solid volume fraction best predicts yield strain, suggesting buckling is the main yield mechanism.

Background:

Cancellous bone exhibits complex mechanical properties crucial for skeletal integrity.
Understanding the factors influencing yield strain is vital for predicting bone failure and designing orthopedic implants.

Purpose of the Study:

To investigate the relationship between compressive yield strain and microstructural properties of bovine cancellous bone.
To determine the influence of trabecular orientation and density on bone's yield behavior.

Main Methods:

Compressive yield strain was measured in 61 bovine cancellous bone specimens.
Statistical analyses (correlation, regression) were used to assess relationships between yield strain and structural density, bone density, and trabecular orientation.
Sensitivity analysis was performed using different definitions for yield point and zero strain.

Main Results:

Yield strain showed a significant positive correlation with structural density (R2=0.319) and a negative correlation with bone density (R2=0.145).
Bone solid volume fraction (Vv) was the best predictor of yield strain (R2=0.337).
No significant relationship was found between yield strain and trabecular orientation (R2=0.051), indicating isotropy.

Conclusions:

Compressive yield strain in cancellous bone is largely independent of textural anisotropy.
The findings suggest that buckling of trabeculae is the primary mode of failure in cancellous bone under compression.
Yield behavior can be characterized by a maximum strain yield criterion, with bone density and volume fraction being key determinants.
