The purpose of this study was to determine the effect of Haversian remodeling on the tensile properties of human cortical bone by testing specimens containing, as far as possible, a single type of bone tissue.
Fifty-one specimens were prepared from sixteen fresh human tibias, removed at autopsy. Age range was 19–35. Regions were selected so that the specimens would consist almost exclusively of either primary bone or Haversian bone.
The ultimate tensile strength, ultimate strain and Young's modulus of elasticity were determined at a loading rate of 0.05 mm s−1. The primary bone specimens were found to have a significantly higher ultimate tensile strength and modulus of elasticity than those formed of Haversian bone.
