Introduction / Purpose:
The subchondral bone plate plays an important role in the load transfer across joints. The
subchondral bone density distribution is a reflection of the loading history of the joint,
and the heterogeneous density distribution expected to be reflected in the subchondral
bone material properties. The goal of this study was to evaluate the strength of the
subchondral bone plate of the canine talus and to correlate it to the subchondral bone
density.
Methods:
On twenty, paired, cadaver tali of different large breed dogs, test points were defined on
the subchondral bone plate. At these points the mechanical strength was determined by
indentation testing, registering the maximum penetration force, and the density was
measured by means of computer tomographic osteoabsorptiometry (CTOAM).
Results:
Neither the density nor the strength were distributed homogeneously over the surface of
the subchondral bone plate. In all specimens, a high correlation was found... between the
subchondral bone density and the mechanical strength. The coefficient of determination
(r
2
) ranged from 0.78 to 0.96 with a mean of 0.89 and was statistically significant (p <
0.01). The location of the density maxima matched the location of maximal mechanical
strength. There was no significant difference in the location of the density maxima and
the strength maxima (p-value = 0.512).
Discussion / Conclusion:
CTOAM provides a non-invasive opportunity to not only assess and visualize the density
of the subchondral bone plate on densitograms but also the mechanical strength, and to
perform longitudinal studies on subchondral bone density and strength in dogs.
