Abstract
Our previous articles on the mechanical properties of single osteons (ASCENZI and BONUCCI, 1968, 1971, 1972) and that describing a method for isolating osteonic lamellae (ASCENZI et al., 1973), all serve to support the view that the compactness of. haversian systems is strengthened by the presence of lamellae whose fiber bundles have an Almost transversal spiral course. Accepting this as a premise, we have now developed a research method able to yield direct evidence on the tightening function of these same lamellae through measurement of the internal pressure which eventually leads to the fracture of cylindrical osteon samples.
