Abstract and keywords

Relations between mineralisation and mechanical properties have been investigated in human femoral compacta. Evidence of age-related changes in physical properties of bone, independent of mineral density, is provided by significant (P < 0.05) partial correlation between ultimate tensile stress and age. However, 75 per cent of variance in ultimate tensile stress, and 85 per cent of variance in ultimate compressive stress could be accounted for by variation in mineral density.

Keywords: bone; mineral density; mechanical properties
