title: [The physical resistance of secondary osteons in relation to the arrangement of collagen fibers].
abstract: In two dogs, 6 months and 4 years aged, the microhardness of secondary osteons was studied in its relationship to the arrangement of collagen fibers. The results obtained indicate that there are no differences when osteons with the same degree of mineralization but different arrangement of collagen fibers are tested. The possible role played by collagen bundles on the microhardness of bone are briefly discussed.
