Abstract

Until now, the mechanical properties of the microcalluses that form in human cancellous bone have been unexplained. We measured the micro‐hardnesses of microcalluses in cancellous bone, of the trabeculae within the microcalluses, of the trabeculae adjacent to microcalluses, and of trabeculae lacking microcalluses in a human tibia and femur. We observed no important differences between materials at the four different sites. Because the microhardness of bone is very closely related to its stiffness, this finding indicates that microcalluses are likely to stiffen the trabeculae in which they are formed, even though they may surround unhealed fractures of the cancellous trabeculae.

The thermal conductivity was about 7 × 10^−4^ cal/cm/sec/°C, that is about the same as for other tissues.
