The canal system in the diaphysial compacta of the femur in some mammals.

The Haversian canal system in the diaphysial compacta of the femur in 4 mammalian species (dog, pig, bovine, horse) was studied on the decalcified bone using a method developed by the authors. In the microscopic studies we found that in all species the network aspects vary with the depth of the compacta layer. In all layers, there is a background of longitudinal canals with more or less regular trajectories describing large curves.

Comparative aspects of the density and diameter of Haversian canals in the diaphyseal compact bone of man and dog.

By using an original method, the authors injected the system of canals and then studied microscopically their network in the femoral diaphysis of man and dog. In the human bone, the density varies between 1.09 and 2.
