Also, all mechanical tests correlated with bone mineral as determined by quantitative single-energy computed tomography. In general, bone mass measures correlated better with bone strength than did bone density measures. However, the cortical and cancellous bone mechanical properties were not interrelated, which suggests a separate regulation of the strength of these two types of bone. Bone mineral may not only have importance for the occurrence of fractures; it should be considered as an important factor in the fixation of fragile bone.
