Implication

Biomechanical study demonstrates strong correlations between mineral density and compressive strength in canine cancellous bone, suggesting non-destructive scans can assess bone strength.

Key Points

To evaluate how accurately photon absorptiometric bone mineral concentration measurements correlate with the compressive mechanical strength of cancellous bone.
Obtained cylindrical cancellous bone specimens from the proximal tibial epiphyses of skeletally mature mongrel dogs.
Performed 125I photon absorptiometric bone mineral assays alongside low strain-rate axial compression testing.
Evaluated assay reproducibility and applied linear and power regression models to correlate mineral content and elastic modulus with compressive mechanical metrics.
Bone mineral concentration correlated strongly with ultimate strength (r = 0.92) and yield strength (r = 0.89), and moderately with elastic modulus (r = 0.82), ultimate energy absorption (r = 0.79), and yield energy absorption (r = 0.73).
Correlations between mineral concentration and both ultimate strain (r = −0.14) and yield strain (r = −0.18) were statistically insignificant.
Linear regression coefficients predicting ultimate and yield strength from elastic modulus were statistically indistinguishable from values reported in human bone.
