One difficulty that arises in an analysis of the cross‐sectional properties of bone is whether to include cancellous bone in the analysis. The purpose of this paper is to determine how different amounts of cancellous bone affect the measurement of structural properties of bone cross‐sections. Thirty‐two tibial and femoral cross‐sections were chosen at random from a series of cross‐sectioned nonhuman primate bones. Geometrical properties were calculated for the cross‐sections, and torsional and bending stress analyses were performed. The results suggest that the effect of including cancellous bone in the analysis is closely related to the amount of bone, where it lies within the cross‐section, and the type of analysis performed. Including cancellous bone in calculations of structural properties of bone cross‐sections may cause the strength and stiffness of the bone to be exaggerated.
