Abstract

Two NMR methods allow one to measure the internal porosity of the trabeculae in cancellous bone, which appears to be constant in the samples examined and independent of the total porosity or the bone volume fraction of the cancellous bone. The consistency of the results showed that η, the ratio of the amount of intratrabecular liquid ¹H to the amount of collagen ¹H, is of the order of 1. Thus, the results demonstrate that not only the density, but also the ratio between pore space and total volume is approximately the same in cortical bone as in the trabeculae of cancellous bone.
